Large transport airplane control loading simulator

Abstract

The invention provides a large transport airplane control loading simulator. The large transport airplane control loading simulator comprises a mechanical system and a control system. A high-precision absolute value encoder is used for acquiring the control quantity of a joystick; the force exerted by a control surface on the joystick is calculated by a computer, and the acting force on the joystick is controlled by controlling a high-precision control loading simulator. The force on the joystick is enabled to change along with the change of the flight height and the velocity of the airplane; the working condition of the control system during automatic pilot is simulated; emergency disposal training of the airplane control system in case of special situations is realized; the trim, namely a zero moment point adjustment process, of the elevator is simulated, and the driving fatigue of the flight crew is reduced and eliminated. The high-precision large transport airplane control loading simulator is beneficial for improving the flight training benefit and the fidelity of the flight simulator.

Description

technical field [0001] The invention relates to the technical field of flight simulators, in particular to a control load simulation device for a large transport aircraft. Background technique [0002] In the actual flight process, the control stick is connected to each rudder surface of the aircraft through the transmission mechanism, and the aerodynamic force acting on the rudder surface acts on the control stick through the transmission mechanism, and the control force changes with the flight altitude and speed of the aircraft. In the process of using the flight simulator to realize the flight simulation training, the realistic joystick force makes the pilot have an immersive feeling and can achieve satisfactory training results. The traditional spring control load simulation system can realistically provide aerodynamic feedback, but its disadvantages are: it is impossible to realize that the force on the control stick changes with the flight altitude and speed of the ai...
