Tungsten alloy counterweights are commonly used to optimize the control performance of aircraft in the field of aerospace, such as elevator, rudder, inertial systems, aileron and so on. The properties of high density and environmentally friendly of tungsten alloy also make its counterweights have more advantages than other counterweights that made of traditional materials (steel, iron or lead), which are widely used in aerospace.

 

For an high-speed aircraft which is flying in the sky, a good stability and balance is the primary condition to ensure the flight safety. In the actual flight, the aircraft is required to achieve the heading shift by controlling the rudder, it can be called direction control. The direction control and lateral control are inextricably linked and coordinated with each other. The aircraft lateral control (the aircraft pinwheeling around the longitudinal axis of the body) is to achieve by the ailerons of airplane. So what is the aircraft's ailerons? Ailerons are an important part of the aircraft flight control surfaces, which enabled the aircraft to produce the rolling torque, in order to ensure the lateral control of aircraft. The effect of lateral control is to control the aircraft to pinwheel around the longitudinal axis, in order to achieve a turn in the horizontal direction. Aileron is located outside of the aircraft wing, it is a relatively narrow and long moveable airfoil.
