Aircraft Wheel Design and Manufacturing

The landing gear is one of the most critical systems in any aircraft, ensuring takeoffs and landings are stable and safe. Here at NMG Aerospace, we have been designing and manufacturing aircraft wheels and landing gear components since 1967. We have supplied countless clients in a diverse range of industries with the landing gear parts they need to keep their aircraft at peak performance.

NMG Aerospace is a leading manufacturer of nose and main aircraft wheels, brake systems, steering kits, and linear actuation components. With our experience in aircraft wheels and tire construction, we can readily fulfill the strict quality standards of the aerospace industry. In fact, we have designed aircraft wheels and landing gear components for commercial airlines, business jets, and even military aircraft. So, you can depend on NMG to deliver high-quality parts that meet your performance and safety requirements.

NMG Aerospace has maintained its leadership among aircraft wheel manufacturers for more than 40 years. Our main wheels, tail wheels, and nose wheels offer the durable construction necessary for handling even the intense applications.

Furthermore, our manufacturing capabilities allow us to create wheels from 6” to 30” in diameter with unparalleled precision and efficiency for high-volume production. As a result, we can more readily manufacture the parts you need while working within your time restraints. Additionally, we offer full-service assembly for bearings, tires, and inflation to streamline the installation process. If you are looking for a reputable manufacturer of critical landing gear components, you can depend on NMG Aerospace.

Exceptional Design, Superior Construction

Aircraft wheels are subjected to extreme pressures during takeoffs and landings that occur numerous times per day. In fact, wheels and tires endure some of the most intense conditions of any landing gear component.

For example, temperatures go as low as -40°F at maximum altitude and as high as 392°F during touchdown. Rejected takeoffs are also a possibility, forcing the aircraft’s wheels and tires to withstand the full weight of the aircraft at high speeds in addition to high temperatures. So, aircraft wheels and tire construction require precision manufacturing and quality materials to ensure functional performance in these conditions.

Here at NMG, we construct our two-piece aircraft wheels with high-grade magnesium and aluminum alloys. We bolt these two pieces together while leaving a groove near the mating surface, which creates room for an o-ring. The large majority of modern aircraft utilize tubeless rubber tires, so they require an o-ring to seal the rim.

Our aircraft wheels also feature a bead seat area where the tire makes direct contact with the wheel. This is a crucial aspect of aircraft wheel construction, as it will provide support for the tires during the heavy pressure of a touchdown. Therefore, we prestress the bead seat with extreme stress loads during the manufacturing process. As a result, we can directly improve the strength of the area and ensure superior performance.

The following video highlights the extreme conditions aircraft landing gear components, wheels and tires experience both in flight, during takeoff, and landing.

Inboard Half Aircraft Wheel Design

Our aircraft wheel design features an inboard half and an outboard half. However, these parts do not function identically. Both halves offer unique contributions to the performance of the overall wheel assembly.

The inboard wheel half function is to accept and drive the rotors of aircraft brakes mounted on both main wheels. There are several ways to bolt the inner half to the brakes. This is also the most distinguishable feature between the inboard and outboard halves.

When designing the inboard half for high-performance aircraft, we will include one or more thermal plugs. The number of thermal plugs depends on the specific model of aircraft. In situations with intense braking such as rejected takeoff, the tires are exposed to extreme temperatures and pressures, potentially resulting in an exploding of the entire wheel and tire assembly. So, we design the thermal plug cores with alloys with low melting points. As a result, they will melt and cause the tire to deflate before an explosion can occur.

If a tire deflation ever occurs due to the thermal plug failsafe, the deflated tire will require removal and inspection. Nearby wheel assemblies should also be inspected for damages to ensure no other assemblies have been compromised.

Outboard Half Aircraft Wheel Design

The outboard half of the wheel bolts to the inboard half to finish mounting the wheel onto the tire. This half is slightly less complex but no less important. Our outboard wheel half design features a center boss that accepts a bearing cup and assembly. The outer bearing and end of the axle to prevent contaminants from entering the aircraft wheel and tire construction process.

The outboard wheel half also has a valve stem for quick and easy and inflation and deflation of tubeless tires. As a result, tire maintenance and setup is much simpler and quicker with NMG aircraft wheels.
