Description

technical field [0001] The invention belongs to the technical field of aircraft testing equipment, and in particular relates to a vertical tail deflection torque testing device for aircraft processing. Background technique [0002] The aircraft tail includes a horizontal tail and a vertical tail. The vertical tail includes a fixed vertical stabilizer and a movable rudder. The vertical stabilizer is the fixed wing surface part of the vertical tail. However, when the aircraft is disturbed by the air flow and the nose is deflected to the left or right, the aerodynamic force acting on the vertical stabilizer will generate a torque opposite to the deflection direction, making the aircraft Return to the original flight attitude, the rudder is the controllable wing surface part of the vertical tail, and its function is to control the yaw of the aircraft. [0003] At present, the rudder in the vertical tail of the aircraft needs to have a certain deflection torque when it is used. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the rudder in the vertical tail of the aircraft needs to have a certain deflection torque when it is used. If the deflection torque is small, it will be difficult to deflect the rudder due to the effect of air resistance when used in the air, which will affect the flight of the aircraft. Therefore, the aircraft When the vertical tail is processed and produced, it is necessary to test the deflection torque of its rudder, but at this stage there is a lack of a high-precision deflection torque test device specifically for the rudder in the vertical tail
