Problems solved by technology

The size of the driving force should be appropriate. If it is too large, the aircraft will be too sensitive and difficult to control, and it is easy to stall or damage the structure due to excessive reaction. If it is too small, the aircraft will be too slow
[0004] At present, the main control system of my country's aircraft cannot collect driving force, and there is a lack of pilot control record data when it is necessary to confirm the flight control status and flight fault judgment

Abstract

The invention discloses an aircraft pilot steering force sensor signal conditioning circuit, system and method, and the circuit comprises three groups of signal processing circuits, and the input endsof the three groups of signal processing circuits are respectively connected with the output ends of a steering column force sensor, a steering wheel force sensor and a pedal force sensor. The outputends of the three groups of signal processing circuits are connected with the input end of the flight parameter and audio recording system; the signal processing circuit comprises an input filter circuit, a first-stage amplification circuit, a second-stage amplification circuit and a second-order filter circuit which are connected in sequence. The driving force of a driver can be collected and recorded in real time, and a basis is provided for flight control state and flight fault judgment. Output signal processing circuits of the steering column force sensor, the pedal force sensor and the steering wheel force sensor are independent of one another and do not interfere with one another.

Description

technical field [0001] The invention belongs to the field of aircraft manipulation, and relates to a signal conditioning circuit, system and method of an aircraft pilot's driving force sensor. Background technique [0002] During the flight of an aircraft, the pilot mainly controls the rudder, elevator and aileron by manipulating the joystick, steering wheel and pedals to change the aircraft from one flight state to another to complete takeoff, climb, cruise, and descent. , landing and other flight maneuvers. Maneuverability is one of the important flight qualities of an aircraft, and it is also an important content of flight mechanics research. [0003] Pilots need appropriate driving force to precisely control the aircraft by applying the driving force, and there are certain requirements for the magnitude, direction and change of the flying state (speed, overload) of the aircraft in various situations . The size of the driving force should be appropriate. If it is too l...
