Abstract

The invention relates to an aircraft deceleration method and device based on an air rudder, and relates to the technical field of aerospace. Multiple air rudders are symmetrically arranged at the tailof an aircraft. The method comprises the following steps: when the actual flight speed of the aircraft exceeds the preset flight speed, generating preset rudder deflection angles corresponding to theair rudders according to the deviation between the actual flight speed and the preset flight speed; generating a real rudder deflection angle of each air rudder according to the current attitude angle of the aircraft and the installation orientation of each air rudder; generating a final physical rudder deflection angle instruction of each air rudder according to the preset rudder deflection angle and the physical rudder deflection angle of each air rudder; and each air rudder deflects according to the corresponding final real rudder deflection angle instruction. According to the method, no extra speed reducer needs to be added, the flight speed of the aircraft can be controlled by using the aerial rudder of the aircraft, and the flight attitude stability of the aircraft in the speed reduction process can be ensured.

Description

technical field [0001] The invention relates to the technical field of aerospace, in particular to a deceleration method and device for an aircraft based on an air rudder. Background technique [0002] Traditional aircraft deceleration methods mainly include rigid aerodynamic decelerators, parachute deceleration, etc., while traditional aircraft deceleration methods require additional deceleration and anti-rotation devices on the aircraft, which will increase the negative mass of the aircraft, and bring about the structural design and control system of the aircraft. come with greater difficulty. [0003] With the rapid development of aircraft technology, at this stage, new deceleration technologies such as flexible aerodynamic reducers, thrust reversers, and combined deceleration devices have been developed. However, due to the lack of maturity of the above technologies, these new deceleration technologies still exist in the field of aircraft applications. certain limitatio...
