Aviation Universal Drive Shaft Helicopter Fan Drive Shaft Lightweight Alloy Steel

1.Product Description:
The helicopter fan drive shaft is a critical component in the helicopter power transmission system, primarily responsible for transferring engine power to the main rotor or tail rotor to achieve lift, propulsion, and directional control. The product is made of high-strength alloy steel, titanium alloy, or composite materials (such as carbon fiber), combining lightweight properties with fatigue resistance.

2. Product Features:

(1)Lightweight: High-strength alloy steel (e.g., 4340 steel), titanium alloy (e.g., Ti-6Al-4V), or composite materials (carbon fiber) ensure reduced weight while maintaining fatigue life.

(2)Large Angular Deflection: Through structural and process optimization, the product can achieve a maximum operating angle of 51°.

(3)Extreme Temperature Resistance: Withstands engine high temperatures (locally exceeding 200°C) and high-altitude low temperatures (-60°C). Anti-corrosion coatings (e.g., cadmium plating, nickel-based alloys) protect against salt spray and humid environments; sealed designs prevent sand and dust ingress.

(4)High Torque Capacity: Transmits high torque output from the engine (especially turboshaft engines). As the gearbox reduces engine speed from tens of thousands of RPM to a few hundred RPM for the main rotor, the resulting torque increase must be borne by the drive shaft.

4. Product Application

(1)Transport Helicopters: Responsible for personnel and cargo transport, the reliable operation of the fan drive shaft ensures flight performance in various complex environments.

(2)Tourism and Sightseeing: In scenic areas such as Zhangjiajie and Guilin, the high reliability of the fan drive shaft in helicopter sightseeing projects ensures smooth flights, providing passengers with a safe and comfortable aerial experience.

(3)Medical Rescue: In emergency medical rescues, such as patient transfers in mountainous or maritime environments, medical rescue helicopters like the EC135 rely on the dependable operation of the fan drive shaft to quickly reach the scene and return safely.

(4)Inaccessible Areas: In remote regions such as mountainous areas or islands, civilian helicopters transport goods, with high-quality fan drive shafts ensuring reliable power transmission to complete cargo missions.
