The application of high density tungsten alloy in aerospace

The additional weight often need to keep in the limited space in the aerospace industry. Tungsten alloy counterweight can increase the sensitivity of the aircraft control mechanisms and keep the operational control of the aircraft in the acceptable range.
 
It is very dangerous vibration in aircraft engine and propeller propulsion system in dynamic element. So you need to use a lot of balance weight to reduce or even eliminate the vibration caused by imbalance quality of the external rotating parts. Tungsten alloy counterweight comes in at many of the propeller design control system as a fault protection mechanism. Tungsten alloy is better than and higher than the traditional balance of materials, such as lead or steel: the first is the high density tungsten alloy, so that we can use smaller components to reduce the weight of the whole system. Traditional balance lead materials will have elastic deformation in the normal temperature, but tungsten alloy is very stable.
 
The applications of Tungsten alloy in aerospace, including the following aspects:
 
1. The gyroscope rotor material. Gyroscope is the navigation and control system of the brain in aircraft, satellites, all kinds of missile and spacecraft nuclear submarine: the alloy density inhomogeneity leads to the gyroscope rotor material failure, the stability of a gyroscope improved as the revolving body weight increased, using high-density tungsten alloy as a gyroscope rotor can make its stability and control precision increased greatly.
 
2. Telex flight control system introduced a small batch of tungsten alloy into flight control joystick to increase inertia, and thus to find the "feeling" of relating the elevator and aileron under the traditional control.
 
In addition, high density tungsten alloy is also widely used in aileron, static and dynamic balance weight on both sides of the rudder and the balance weight of helicopter rotor blades.
