Motor Actuator Valves and Their Uses

by NMG Aerospace | Jan 14, 2025 | Uncategorized

What is a Motor Actuator Valve?

A motor actuator valve, or motorized valve with an actuator, is a valve that opens and closes without human intervention thanks to a motorized power source. Motor actuator valves direct the flow of fluids and air in a wide range of applications, including aircraft and aerospace systems. This includes landing gear, engine control, fluid transfer, landing gear, and others.

A motorized valve with an actuator is considered an automated system, since the valve can be controlled by an input signal rather than a human operator.

Components of Motor Actuator Valves

There are three primary components of a motor actuator valve: the valve body, the actuator, and the actuator motor.

Valve Body

The valve body is the main component of a motor actuator valve. The valve body directs the flow of media within an aircraft system or aerospace fluid transfer assembly. The media differs depending on the application, but common media in aerospace contexts include water, hydraulic fluid, air, and combustible fuels. Motorized valve bodies are usually metal or plastic, depending on fluid exposures and other variables of the motor actuator valve’s service environment.

Actuator

The actuator converts power from the motor into mechanical motion, controlling the motorized valve.

Motor

The actuator motor powers the actuator. Usually, the motor and the actuator are connected by a gear or belt for power transfer.

Types & Applications of Actuator Valves Used in Aerospace

Motor actuators and motor actuator valves are among the most important components of any aircraft platform. Actuators trigger a wide range of essential aerospace functions, from simple valves to autopilot and landing gear operations. Motorized valves with actuators are extremely versatile, with multiple varieties found throughout many aircraft platforms.

Pneumatic Actuator Valve

A pneumatic actuator valve uses compressed air as a power source. Common applications for pneumatic actuator valves include high-cycle and rapid-cycle functions. Pneumatic actuation is an excellent choice for hazardous or explosive environments since there is no sparking. Pneumatic actuator valves are also well suited to high-temperature environments when paired with high-temperature seals.

Many pneumatic actuators use spring-return technology to move the valve into a “fail-safe” position if power or pneumatic pressure is lost for any reason, a desirable safety benefit for the aerospace industry.

Electric Actuator Valve

Electric actuator valves offer high flow precision for virtually any media used in aerospace applications, including nitrous oxide and combustible fuels. Electric actuators ensure extremely accurate positioning of valves and dampers, resulting in tight control of media flow. In addition to being highly dependable, electric actuator valves are smooth and quiet, which can be valuable in certain applications.

Many electric actuator valves offer a fail-in-place or “lock-up” feature. This means the valve freezes in place if the system loses power. Additionally, some electric actuator valves are fail-safe, like pneumatic actuator valves, though it should be noted that these are more expensive. Some companies may decide between fail-in-place and fail-safe electric actuators based on their budget and the application in question.

Hydraulic Actuator Valve

Hydraulic actuator valves are used to control the flow of water, air, fuel, hydraulic fluid, and other media that may be used in aerospace applications. Hydraulic actuator valves tend to be durable and powerful, making them a desirable option for high-force applications. Hydraulic actuator valves are also highly customizable, offering a wide range of configurations for different aerospace applications and aircraft systems.

Thermal Actuator Valve

Thermal actuator valves are controlled by a thermal actuator, which triggers mechanical motion, such as piston extension, in response to changes in temperature. Thermal actuator valves are highly precise and extremely accurate, a valuable asset in aerospace, where precision is often mission-critical. Thermal actuator valves provide constant modulation thanks to instant reactions to even minor changes in temperature, making them an excellent option for systems that require strict temperature control, such as fuel and oil temperature management and cabin environmental systems.

This team should consist of key stakeholders, including suppliers and customers, as well as relevant job functions that influence the corrective action process. Their collaboration ensures a thorough examination of the issue. Effective root cause analysis training prepares each team member by clarifying their roles and responsibilities. 

The process of root cause problem-solving typically involves a series of structured steps, as outlined below:

Define the Problem

After the RCA team is selected, the next step is defining the problem. This involves understanding the problem’s significance, impact, and size and identifying which product, process, or defect is at fault in the safety or reliability incident. It’s important to differentiate between the effect (outcome of a problem) and the cause (the origin of a problem). A clear and agreed-upon definition ensures everyone is aligned from the start.

Causal Factor Identification

Once the problem is defined, the next step is identifying the causal factors that contribute to the issue. Understanding all factors that contributed to the undesirable condition, situation, nonconformity, or failure enables a comprehensive review of the circumstances that led to the problem. These causal factors could include design flaws, procedural errors, human factors, or even environmental influences. 

Root Cause Identification

In this step of root cause problem-solving, root cause identification tools are employed. The goal is to identify both common and special cause variations. 7 different root cause analysis techniques include:

• Process Mapping
• Fishbone Analysis (Ishikawa)
• Cause and effect
• FMEA (Failure Mode and Effect Analysis)
• 5 Whys
• Failure Tree Analysis (FTA)
• Root Cause Chain 

By analyzing each variation, teams can stabilize processes to eliminate special causes and enforce control measures to reduce common cause variations. This ensures that all critical factors contributing to the problem are addressed.

Define Corrective Actions

After root causes are identified, the RCA team is responsible for defining corrective actions that will address the root causes and permanently prevent the undesirable condition, situation, nonconformity or failure from recurring. Root cause and corrective action training gives teams the tools to prioritize solutions that stabilize and improve processes.

Understanding Solenoid Valves and Their Purpose

by NMG Aerospace | Sep 12, 2024 | Uncategorized

Solenoid valves are crucial components for precision and reliability in aerospace. But how does a solenoid valve work to maintain reliable aircraft performance? The purpose of these valves is to precisely regulate fluid and gas flow across various critical aerospace systems, from braking mechanisms to deicing equipment. Aerospace systems commonly use hydraulic solenoid valves, pneumatic solenoid valves, electric solenoid valves, gas solenoid valves, and other types to serve essential functions within an aircraft.

What Is a Hydraulic Solenoid Valve?

A hydraulic solenoid valve controls hydraulic fluid flow in high-pressure applications. These valves manage hydraulic power in aerospace systems like landing systems, brakes, and flight controls. These valves use an electric current to actuate the valve, ensuring precise control of hydraulic fluid flow. This precision is vital for optimal performance and safety of aerospace systems. For example, in landing systems, hydraulic solenoid valves ensure smooth and reliable deployment and retraction of gear during extreme environmental conditions.

Components of Solenoid Valves

In aerospace systems, solenoid valves consist of three critical components: the coil, plunger, and body. These parts work together to ensure precise fluid and gas control and system reliability.

The Coil

The wire coil is the core of the solenoid valve. When electrical current flows through it, the coil generates a magnetic field that moves the plunger within the valve. The responsiveness and efficiency of a solenoid valve are determined by the coil’s material, voltage rating, and power consumption.

The Plunger

The plunger is a movable metal component within the solenoid valve. When the coil is energized, the magnetic field pulls the plunger, causing it to open or close the valve to control fluid or gas flow. High-quality materials and exact dimensions are crucial for accurate and reliable valve operation, particularly in high-stress aerospace environments.

The Body

The body of a solenoid valve houses all of the internal components. It also features inlet and outlet ports through which fluids or gases flow. The body is designed to withstand high pressures and harsh environmental conditions. This durability and structural integrity are vital for ensuring long-term reliability and performance of the solenoid valve.

Types & Applications of Solenoid Valves Used in Aerospace

Different types of solenoid valves are used in aerospace, each suited to specific applications:

Pilot-Operated Valve

Pilot-operated solenoid valves use a small pilot valve to control a larger valve. This type is ideal for high-pressure applications where direct control would require excessive force. By employing a pilot valve, these solenoids can manage large flows efficiently and with lower power consumption. They are commonly used in fuel and hydraulic systems in aircraft where precise control is critical.

Direct-Acting Valve

Direct-acting solenoid valves operate without a pilot valve. Instead, the electromagnetic force directly moves the plunger to open or close the valve. This makes direct-acting valves simpler and faster in operation and well-suited for high-stress aerospace environments. These valves are ideal for critical safety systems, such as emergency shut-off valves in fuel and hydraulic systems.

2-Way, 3-Way, and 4-Way Valves

2-way valves have two ports and are used to allow block fluid flow. They are commonly found in simple on/off applications. With three ports, 3-way valves can direct fluid between two different paths. This makes them suitable for more complex control scenarios, such as switching between landing systems. Lastly, 4-way valves have four ports that control double-acting actuators. They are essential in systems that require reversing the direction of fluid flow, such as flight control surfaces.

Worn-out parts, such as engine components, filters, electronics, and brake parts, can cause serious problems if they fail to meet expectations while the aircraft is in use. Upgrading and replacing components on the recommended schedule, or when signs of wear begin to appear, is key to ensuring safe operation of the aircraft.

Maximize Aircraft Performance

Some aircraft components can continue to function past their recommended service life, but they are unlikely to perform as well as a new part. The fading efficacy of a worn-out part can have a ripple effect throughout the aircraft. Upgrading aircraft components regularly contributes to the superior performance of the aircraft as a whole.

Extend Component Lifespan

Upgrading smaller components within a larger system can meaningfully extend the life of the larger system. Replacing belts and valves on a regular basis, for example, is vital for maximizing the lifespan of the engine.

Comply with Regulatory Standards

While upgrading some aerospace components is a judgment call, other aircraft upgrades are mandated by regulatory bodies. Keeping up with the required schedule is critical to maintaining compliance.

Save on Maintenance Expenses

Regularly upgrading aircraft parts can help prevent more significant expenses down the road. Keeping up with routine maintenance minimizes the risk of larger malfunctions or expensive repairs, which are often far more costly and time-consuming to resolve.

Commonly Replaced Aircraft Components

Some aircraft components can last for years or even decades, while others must be replaced or upgraded on a schedule. This largely depends on the function of the component and its rate of wear while in service. Commonly replaced aircraft components include:

Wheels and Brakes

Aircraft wheels and brakes are designed to perform under incredible duress, absorbing the full weight and momentum of the aircraft while performing critical functions. Even those designed for maximum longevity must be upgraded or replaced on a regular basis to ensure optimum function. Routine maintenance for aircraft wheels and brakes should include close inspection and regular replacement of wheels, brake pads, and other components as needed.

Avionics Systems

Many aircraft are engineered and built to last for decades, but the lifecycle of avionics is much shorter. This is partially due to the speed of advancements in electronics, as well as the shorter lifespan of delicate avionics components. In order to avoid obsolescence, avionics systems should be upgraded according to a regular schedule.

Engine Components

Aircraft engines are high-performance machines that convert tremendous amounts of power into motion, often in intense conditions. Replacing and upgrading aircraft engine components, such as belts, filters, and fan blades, is critical to extending the life and improving the performance of the engine.

Exploring the Multifaceted World of Aircraft Brake Technologies

by NMG Aerospace | Jun 19, 2024 | Uncategorized

A Brief Primer on Aircraft Braking Systems

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.
