Safety is important in many industries, but in the realm of aerospace manufacturing, there is a tremendous price to pay when safety is not prioritized. And safety goes far beyond evacuation slides, life rafts, and emergency brakes. Every single component of an aircraft, from a single screw to a massive fuselage, contributes to its safe operation, both in the air and on the ground. When safety is a priority, everyone—from the people aboard the plane to the bystanders on the ground—benefits.
A robust safety strategy is the product of many different factors, but at its core, safety starts with quality.

Different types of aircraft rely on a variety of braking systems for safe operation. From wheel brakes on commercial planes to rotor brakes on helicopters, braking systems are critical for safety and performance.
Each type of aircraft braking system has unique features and functions based on its position and purpose.
Aircraft Wheel Brakes
Aircraft wheel brakes are incorporated into the aircraft’s landing gear. Aircraft wheel brakes must apply tremendous force to fast-moving wheels to slow or halt their rotation and bring the aircraft to a stop on the tarmac or runway. All components of an aircraft’s braking system must withstand the friction and heat generated by the braking process.
Different types of aircraft must perform braking maneuvers in different environments. Commercial aircraft wheel brakes are operated almost exclusively on well-maintained airport runways. These runways tend to be long, allowing ample time for braking. Military aircraft, on the other hand, often must land on fields, rough surfaces, or aircraft carriers with extremely short runways. These strenuous and often unpredictable situations put considerable stress on the aircraft’s braking system, which must be taken into account during the design process.
The tremendous forces of aircraft wheel braking systems are operated entirely via a foot pedal, controlled by a human pilot.
Helicopter Rotor Brakes
The purpose of helicopter rotor brakes is to stop the rotation of the helicopter’s blades. Helicopter pilots do not deploy the rotor brakes until after the helicopter has landed and the engine has been shut down. Only after the spinning rotors have come to a complete stop is it safe for the pilot and passengers to exit the helicopter.
Helicopter rotor brakes are very different from aircraft wheel brakes. While wheel brakes, which are integrated into the aircraft’s landing gear, have virtually no impact in the air, it is incredibly dangerous to activate helicopter rotor brakes while in flight, even for a moment. For this reason, helicopter rotor brakes are activated with a manual lever, instead of a foot pedal that could be tapped by accident.
Brakes for Homebuilt Aircraft
Many homebuilt aircraft are entered into short takeoff and landing (STOL) competitions. Pilots of homebuilt aircraft strive to execute a complete stop as quickly as possible after landing, often less than fifteen feet from the touchdown site.
Needless to say, fast-acting brakes must be able to apply and withstand tremendous pressure. And because these aircraft are homebuilt, the landing gear and braking system installation process must be simple enough for the average STOL competitor to do it safely. Performance and ease of use must both be considered during the design process.
Aircraft Brake Materials
Material choice for aircraft brakes can be a balancing act. Aircraft brake materials must be durable enough to withstand heat, pressure, vibration, and other forces. However, aerospace manufacturers must also be mindful of weight, since heavy materials affect the fuel economy and aerodynamics of the aircraft.
Some common materials used for aircraft brakes and landing gear include:
Metals
Disc brake rotors are often made from iron or steel. Brake linings also frequently contain metals and may be semi-metallic or sintered.
Rubber
Braking system hydraulics are operated with rubber components.
Carbon Fiber
Some aerospace manufacturers have started using carbon fiber as an alternative to traditional metals in aircraft braking systems. Carbon fiber is light, strong, durable, heat resistant, and can last a long time. As carbon fiber becomes less expensive, its popularity is expected to grow.
The Right Braking System for Your Aircraft
Designing and building the right braking system and landing gear for a given platform requires understanding both the aircraft and its anticipated service environment. The experts at NMG have years of experience in aircraft brake manufacturing and deep knowledge of the many variables to consider during the design process. From the early stages of ideation and design to material selection, manufacturing, and quality testing, NMG can support every step of the aircraft brake production process.
NMG is proud to offer a robust portfolio of aerospace testing capabilities to validate the environmental, structural, and functional performance of aircraft parts, products, and components. We’ve aligned our capabilities at our state-of-the-art aircraft testing and qualification facilities with RTCA DO-160 and other critical aerospace testing standards to ensure that we can help our customers remain competitive and current in the aerospace industry. In addition to standard tests, we can also design custom aerospace testing protocols for R&D and predicting outcomes of unique situations and environments. Whether we’re running an industry-standard test, such as RTCA DO-160, or designing a custom aircraft testing protocol, we emphasize accuracy, reliability, and repeatability to ensure quality data.
NMG’s Qualification Testing Capabilities
Temperature Testing
From the heat of launch to the extreme chill of altitude, aerospace components are often exposed to a wide range of extreme temperatures while in service. The purpose of temperature testing is to predict how a given material or component will perform under these circumstances. NMG’s thermal shock and environmental test chambers can recreate these dramatic temperature swings or prolonged periods of extreme exposure in a controlled aerospace testing laboratory environment.
Altitude Testing
Changes in altitude are often accompanied by drastic changes in both temperature and pressure. Aircraft parts and materials must be able to withstand these changes while continuing to fulfill their intended purpose. Laboratory altitude testing allows manufacturers to demonstrate how an aircraft component will handle altitude changes without ever leaving the ground.
Humidity Testing
Many aircraft components are exposed to humid environments while in service. While excess humidity can cause a number of issues, the greatest is corrosion, which can lead to mechanical failure and electrical shortages. Understanding the effects of humidity is vital to designing a system that can maintain performance when exposed to humid conditions. NMG leverages RTCA DO-160 humidity testing methods to allow manufacturers to qualify the effects of humidity on aerospace components in a controlled environment so they can validate performance.
Shock and Crash Safety Testing
Even in normal operations, an aircraft—and its many components and assemblies—can experience a variety of shocks. Landing, taxiing, strong winds during flight, and other standard events can transmit shock throughout the aircraft. RTCA DO-160 operation shock and crash safety testing is designed to demonstrate how aircraft parts respond to these forces by recreating shocks in an aircraft testing laboratory setting.
Vibration Testing
Propellers, fans, turbojets, and other aerospace mechanisms generate a lot of vibration while in service. The intensity and duration of vibration can vary depending on the aircraft and the flight. Aircraft components can be subjected to standardized vibration profiles in an aerospace testing lab based on what they may encounter in service to ensure compliance with performance standards. NMG has deep knowledge of the vibration testing methods for each aircraft outlined in RTCA DO-160.
Waterproofness or Fluid Susceptibility Testing
From puddles on the runway to precipitation in the skies, aircraft are exposed to moisture. Fluid susceptibility testing assesses a component’s vulnerability to fluid ingress and fluid contamination. NMG can recreate a wide range of fluid exposure scenarios in a controlled laboratory setting based on the unique environment of each component. RTCA DO-160 test methods range from full immersion or soak testing to minimal contact or dripping.
Icing Testing
Changes in altitude, humidity, and temperature can lead to ice buildup on aircraft. Icing test protocols can recreate several icing scenarios, based on the location of a component within an aircraft, and determine whether performance is compromised by icing. This type of aerospace testing is conducted in a specialized environmental test chamber.
Other Tests: RTCA DO-160 and Custom Protocols
NMG’s aerospace and aircraft testing facilities are equipped for a wide range of additional validation, performance, and conditioning tests. In addition to RTCA DO-160 testing, we can design custom protocols and combine multiple variables to recreate unique service environments based on our customers’ needs.
What Is RTCA DO-160 Testing?
RTCA stands for Radio Technical Commission for Aeronautics. RTCA DO-160 is an aerospace testing standard that describes laboratory testing methods for assessing the performance of aircraft parts in different environmental conditions. RTCA DO-160 includes 23 different aerospace testing procedures, such as temperature, humidity, and vibration testing. Each RTCA DO-160 test procedure includes options for tailoring the method based on the type of aircraft or component undergoing testing.
The RTCA is not a government entity, but many RTCA DO-160 test procedures have been adopted by federal agencies, such as the United States Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA).
Continuous Improvement
NMG’s robust in-house aerospace testing capabilities are an important pillar of our commitment to continuous improvement. While aircraft testing is vital to demonstrating compliance, it also reveals data and insight that can pave the way for the next generation of exceptional aerospace components and platforms.

Aircraft wheels and brakes must perform critical functions under extreme duress. The aircraft braking process generates tremendous pressure and heat, which puts considerable strain on landing gear components.
Understanding these stressors during the landing gear design process is key to manufacturing airplane wheels and brakes that function as intended.
The Landing Gear Design Process
Effective landing gear design starts with a comprehensive understanding of the landing gear’s performance requirements and service environment. Manufacturers may ask a few questions to guide the landing gear design process, including:
How large and heavy is the aircraft?
Will the aircraft perform take-offs and landings primarily on well-maintained runways or unpredictable field sites?
How much heat will be generated by braking forces?
In some cases, a totally new landing gear assembly or component concept will call for a clean-sheet approach to the design process. However many manufacturers can use an existing landing gear design as a jumping-off point.
After the design stage, manufacturing will look slightly different for each component of the landing gear assembly.
Aircraft Wheels: The Manufacturing Process
Most aircraft wheels are two-part assemblies, called a split-wheel construction. The inboard and outboard wheel halves are designed differently, since the inboard wheel half drives the brake rotor. The two halves are bolted together, with a high-performance O-ring creating a tight seal.
Airplane wheels must be manufactured to withstand tremendous pressure and high heat from heavy braking. For this reason, the most common manufacturing methods for airplane wheels are casting and forging, since both result in incredibly strong wheels. Many aircraft wheels are made from aluminum alloy, but magnesium alloy is also a fairly common material choice. Once the wheel halves have been cast or forged, additional steps may be taken, such as:
Machining grooves or holes into the assembly
Heat treating
Finishing treatments, such as shot peening or anodizing
Brake Rotor: The Manufacturing Process
Manufacturing brake rotors for aircraft landing gear starts with designing and creating a mold, usually with a CNC mill or other machine. The aircraft brake rotor mold is filled with hot liquid iron and compacted to ensure durability. Once the rotor has been cast, a machinist may use precision milling techniques to create level surfaces and meet tight tolerances, and CNC drilling to make precise holes for heat to escape. The final steps of the aircraft brake rotor manufacturing process are polishing and finishing.
Brake Discs: The Manufacturing Process
Aircraft brake disc manufacturing begins with a steel, iron, or composite material plate. The basic shape of the brake disc, called a blank, is punched from the sheet. At this stage, two types of holes may be punched from the aircraft brake disc blank:
Process holes, for mounting the disc
Heat dissipation holes
The size and placement of these holes will differ depending on the design.
Further shaping of the blank may be achieved through heating, flattening, and extrusion. Edges and holes may also be chamfered.

In simple terms, a FAA Repair Station Certification is granted to businesses providing aircraft repair services that comply with U.S. Federal Aviation Administration (FAA) regulations. But there is some nuance that should be understood.
There are plenty of non-FAA aircraft repair facilities that may be capable of repairing an aircraft, aerospace component, or assembly. They may understand aircraft repair and maintenance very well. However, only FAA repair stations can perform maintenance or repairs andapprove that aircraft or system for return to service afterward. Non-FAA repair facilities do not have the credentials to grant such approvals.
Furthermore, FAA repair stations are certified to perform maintenance and repairs only for certain categories of aircraft and aerospace components. For example, the FAA specifies four classes of instrument repairs. An FAA repair station must demonstrate that they have the facilities, equipment, materials, and other resources required for each class. They may only be rated for Class 2 Instruments, or they may be rated for all four classes. A repair station may also receive a limited rating, which means they can only provide repairs for a specific make and model of a given aerospace system or component.
Why contract with an FAA repair station?
There are many reasons to contract with an FAA repair station. Two of the primary reasons are quality and approvals.
From a quality perspective, FAA repair stations are unparalleled. FAA repair stations must demonstrate compliance with the incredibly stringent requirements of the Federal Aviation Administration. This includes:
Intensive personnel training.
Robust quality control and management systems.
Detailed manuals regarding personnel responsibilities and operating procedures.
FAA repair stations also have the authority to approve an aircraft, component, or assembly for return to service once maintenance and repairs are completed. A mechanic or repair facility without FAA certification does not have the same authority. Legally, you cannot put a part on an aircraft unless it comes from an FAA repair station.
How do I know what kind of work an FAA repair station can do?
FAA repair stations display their operating specifications certificate at their facilities and on their websites. If you are seeking to determine the ratings of an FAA repair station while doing online research, search the website for sections titled “Certificates,” “Approvals,” or “About Us.” You are likely to find FAA certifications in one of these areas.
Each certificate will list exactly which classes of repairs the FAA repair station is rated for. There are six categories of repairs, each of which is broken into classes:
Airframe – four classes
Powerplant – three classes
Propeller – two classes
Radio – three classes
Instrument – four classes
Accessory – three classes
The FAA repair station’s certificate will also specify whether the approval is limited to a specific make or model of aircraft or component.

Every element of an aircraft’s brake system has a distinct and essential role. The brakes generate friction to bring a speeding aircraft to a halt, relying on strong materials and precise mechanics to perform reliably. Join our experts as we dive deeply into how aircraft wheel brakes are manufactured!
Steps Involved
Each step involved in engineering brakes for aerospace landing gear is crucial. Aircraft wheel brakes must be designed correctly, manufactured with appropriate materials, and contain all the essential components.
The key to ensuring your aerospace brakes are engineered correctly is to work with a company that values quality above all else. NMG has built extensive quality control checks and processes into our aerospace manufacturing operations, ensuring that every component meets our customers’ requirements!
Design of Aircraft Brakes
Aircraft brakes must be designed to operate reliably in all conditions. To ensure an aircraft can land safely, you should use the proper brake system based on the aircraft’s size, weight, and speed. Four types of modern brakes are designed for aircraft landing gear: single disc, dual disc, multiple disc, and segmented rotor.
Single Disc
Single disc brakes are designed for smaller aircraft. They are set between two pads and connected to each main landing gear leg. The disc is set on the wheel, allowing the disc and the wheel to rotate in unison. As brakes are applied, the caliper presses the pads against the disc braking the aircraft.
Dual Disc
A dual disc system is used for aerospace brakes when single disc systems would not create enough braking friction to land safely. In this design, two discs are attached to the wheel and a center carrier is set between them. When the pilot applies the brakes, the center carrier linings make contact with the two discs and the wheel decreases in speed.
Multiple Disc
Multiple disc systems are designed for large, heavy aircraft. They are built on an extended bearing carrier that holds alternating steel stators and discs plated in copper or bronze. The stators are covered in brake lining which is designed to press against the rotors. Hydraulic pressure on the piston compresses this mechanism, which creates friction, slowing the aircraft wheels.
Segmented Rotor
This brake system is a variation of a multiple disc system, but contains modifications and upgrades. In a segmented rotor brake system, the brake rotors are designed with fixed high friction brake linings which make contact with rotors to slow the wheel. The rotors have slots cut into them, allowing any heat to escape. Segmented rotor brake systems are the standard on high-performance aircraft.
Materials
The rotors of disc brakes have historically been made with either iron or steel. However, this presents a problem for heavy aircraft because of the heat produced from high levels of kinetic energy. This causes steel or iron brakes to lose efficiency – something you can’t afford with aircraft brakes. Instead, many designers have begun using carbon fiber on disc brakes. This decreases the weight of the brake system and improves high-heat performance.
Components
There are various components involved when engineering aircraft brakes. Commercial, business, and military aircraft require high-quality, high-functioning brake sleeves, torque tubes, back plates, and discs that are equally reliable in both low-stress and high-intensity situations.
Common Problems With Aircraft Brakes
Understanding how aircraft brakes are engineered is important, as is knowing how to spot and fix a potential problem. Even the highest quality brakes will face wear and tear, needing maintenance occasionally. Below are three common problems that can be quickly handled when caught early.
Overheating
Aircraft brakes face a common issue: overheating. This could be caused by the design of the brakes or by high-braking maneuvers. To solve this problem, you can utilize a segmented rotor brake system and practice braking in a way that generates less heat whenever possible.
Dragging
If you feel a dragging sensation when letting off of the brake pedal, there could be a problem with the return mechanism, a weak return spring, a warped disc, or air in the brake fluid line. A trusted technician can fix any of those problems.
Chattering
Aerospace brakes can get loud, making a chattering or squeaking noise. This happens if the brake lining is not pressed evenly against the disc. A realignment or replacement of parts may be necessary to fix this problem.

Five Aerospace Manufacturing Industry Trends For 2024
Trends come, and trends go – even in the aerospace manufacturing industry! But how do we know which ones are here to stay? By staying on top of aerospace news and growth, our team of experts has compiled a list of the top 5 trends you will see making a difference in aerospace manufacturing this year. From a focus on sustainability to the use of drones (unmanned aerial vehicles), we can’t wait to see how these advancements benefit our customers in 2024!
1. Increasing Aerospace Sustainability
One of the largest trends is a movement toward global sustainability efforts. This can even be seen in mainstream news as more and more people are discussing the problem of carbon emissions from the excessive use of private jets. With more than 100 countries agreeing to reduce carbon emissions by 5% in 2030, now is the time to focus on sustainability in aerospace manufacturing.
A major focus of the sustainability movement is on using alternative energy sources such as electric flight technology or sustainable air fuels (SAF) – whose emissions have a shorter life cycle. At NMG, we are monitoring further research to ensure our operations advance to be as sustainable as possible.
2. Innovated Propulsion Systems
In a continued desire to reduce the aerospace industry’s environmental footprint, 2024 is bringing innovation to propulsion systems. Manufacturers of these systems face challenges such as the thermal management of engines, noise pollution, and fuel efficiency. However, we see these dilemmas being addressed as our industry takes advantage of improved cooling technologies and sound-reducing devices and introduces sustainable fuel solutions.
3. Artificial Intelligence and Machine Learning
Another trend is artificial intelligence (AI) and machine learning (ML) in aerospace manufacturing and how they can improve operations, reduce costs, and create a safer working environment for employees. This technology can be used for predictive maintenance, autonomous systems, and advanced manufacturing techniques. As more and more people become comfortable with artificial intelligence, we expect aerospace manufacturers to depend on it more than ever before.
NMG drives innovation by utilizing the latest technologies – but a computer could never replace a valuable team member. Our responsive team is dedicated to your product – from concept to ongoing technical support. That is one thing that AI could never do.
4. Utilizing 3D Printing
Production lines in the aerospace manufacturing industry are often waiting on components that are lightweight, intricate, and difficult to produce. The traditional way of manufacturing these parts is slow and costly. However, as 3D printing becomes more advanced, our industry has begun taking advantage of it as a production method. Fused deposition modeling (FDM) and electron beam melting (EBM) allow for faster development of essential aircraft components. The growing use of 3D printing is cost-effective and minimizes waste!
5. Unmanned Aerial Vehicles Production
With the costs of traditional aircraft growing due to component size and quality control – the need for unmanned aerial vehicles (UAVs) has never been higher. UAVs offer a cheaper option for transportation of goods, surveillance, and combat uses. They are also a safer option for industries such as infrastructure inspection and maintenance, eliminating the need for humans to perform risky tasks. As UAVs offer advanced capabilities, we foresee more aerospace manufacturers adding them to their production lines.

Aviation has become synonymous with speed thanks to depictions in movies, video games, and other stories. There is no denying that speed is imperative for most forms of air travel. However, as important as speed is, there is something even more important: the ability to slow down. All the speed in the world is not worth anything if you can’t stop at the end of your flight. That is where the unsung heroes of flight come into play: the aerospace brakes.
What Engineering Considerations Need Made for Making Aerospace Brakes
Functional aerospace brakes are crucial when it comes to the building of a plane or spacecraft. However, even though they exist across the vehicle production spectrum, that does not mean all aerospace brakes are alike. Various considerations need to be made depending on certain factors.
Type of Aircraft
The make and model of the aircraft will determine the type of aerospace brakes necessary for a successful landing. A large cargo plane will need heavy-duty aerospace brakes to halt a massive aircraft traveling quickly. However, a fighter jet with a significantly smaller and nimble body will have different aerospace brake needs. The same can be true for all variations of aircraft, ranging from spacecraft to single-engine planes.
Consumer Needs
Even though all aircraft fly, the individual plane can provide service for various specific tasks. For example, small passenger aircraft can double as postal planes in certain areas. The plane’s determined use will make a difference in its outfitted equipment and, in some instances, the necessary braking apparatuses.
Materials Used
Different materials may be required when manufacturing brakes for any aerospace project. From R&D to manufacturing, the materials used will vary based on the type of component or aircraft being manufactured. Aircraft disc brakes require rubber or latex components to operate the hydraulic aspects, while speed brakes located on wings will be manufactured from the same composites as the wings, spoilers, or flaps.
How Do the Brakes Interact with Other Parts of the Aircraft
Landing Gear
The landing gear is one of the most pivotal aspects of any aerospace design. It is a complex piece of machinery that requires the integration and synchronization of various components; any failure of these components could result in a crash. The landing gear is deployed during the descent of an aircraft to allow the wheels to come into contact with the ground. Once the wheels have begun spinning on the ground, the aerospace brakes are then activated to slow the vehicle. They apply friction and pressure to the apparatus to reduce the high speed of the wheels to the point where the plane can stop safely.
Wings
Speed brakes are an important part when altering the speed of a plane or other aircraft. Panels, spolers and flaps can be built into the wing to slow down the plane while in the air or to lower overall speed for any required maneuvers. Speed brakes catch the wind and produce a negative force proportional to the speed of the plane going in the opposite direction. This will work to slow down the plane, effectively acting as another brake.
Cockpit
The cockpit is instrumental for most of the plane’s functions. It serves as a control center for all the operations required for flight. From here, the speed brakes can be deployed, the landing gear lowered, the brakes against the wheels, and, in some cases, drag chutes released. The pilot orchestrates everything from the cockpit.
