Problems solved by technology
From the perspective of flight quality, software limitations cannot give the pilot an intuitive hint in some complex situations: the aircraft has reached the limit state
In the case of high speed pressure, too fast and too much longitudinal rod control will quickly increase the normal overload of the aircraft, and in severe cases it will exceed the strength limit of the aircraft, resulting in a stall of the aircraft

The invention belongs to an aircraft control design technology, and relates to an aircraft longitudinal maneuvering limit limiting method and a device thereof. The limit limiting device comprises a steering engine (101), a spring pull rod (102) and a sealing outlet (103). According to the aircraft longitudinal maneuvering limit limiting method and the device thereof provided by the invention, an obvious hint can be given to the body of an aviator when an aircraft achieves a limiting condition; the fact that the aircraft achieves a limit state is hinted, so that the aviator needs to take care maneuvering motion; simultaneously, a part of super-control capability is also given to the aviator; the aircraft longitudinal maneuvering limit limiting method and the device thereof are used for emergent maneuvering under emergent conditions; and in addition, compared with simple use of software limit, the aircraft longitudinal maneuvering limit limiting method and device thereof are more intuitionistic and effective.
Description
technical field [0001] The invention belongs to the design technology of flight control, and relates to a method and a device for limiting the longitudinal control limit of an aircraft. Background technique [0002] The limit angle of attack and limit G for conventional fly-by-wire aircraft are usually limited by software. From the perspective of flight quality, the software limitation cannot give the pilot an intuitive hint in some complex situations: the aircraft has reached the limit state. In the case of high speed pressure, too fast and too much longitudinal rod control will quickly increase the normal overload of the aircraft, and in severe cases it will exceed the strength limit of the aircraft, resulting in a stall of the aircraft. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for limiting the longitudinal control limit of the aircraft that clearly prompts the pilot physically when the angle o...
