The arm changing type moment feedback control device comprises a mechanical system and a control system, wherein the mechanical system and the control system comprise a driving rod, a connection rod of the driving rod, two sets of arm changing mechanisms, a spring, a computer and a driving rod potentiometer, each of the arm changing mechanisms comprises a motor, a drive wheel, a gear, a screw rod, a screw rod bracket, a sliding block, a position feedback multiturn potentiometer and an installation bracket of the position feedback multiturn potentiometer, the motor drives the screw rod to rotate to change and combine spring force arms, and spring forces acted on the driving rod are matched with plane dynamic pressure data so as to obtain corresponding longitudinal operation forces during a flight process and stimulate a relationship between the longitudinal operation forces and control surface rotation angles and aerodynamic force. According to the arm changing type moment feedback control device of the training plane, zero moment point regulation is achieved, the driving rod can be controlled to stay at any longitudinal position, the moment of operation of the driving rod by the flight personnel is zero, the driving rod can be released to maintain current states, and driving fatigue can be relieved and eliminated, and high fidelity, stability and smoothness of force simulation of the driving rod are achieved; the arm changing type moment feedback control device is simple in structure, high in reliability and capable of improving training efficiency.

Description

[0001] technical field [0002] The invention relates to the technical field of trainer flight simulation, in particular to an arm-variable torque feedback adjustment device for a trainer. Background technique [0003] In primary and intermediate trainer aircraft, the cockpit is connected with the elevator of the aircraft through a mechanical mechanism, and as the speed and altitude of the aircraft change during flight, the force acting on the elevator will be transmitted to the pilot through the mechanism. on the pole. With the opening of my country's low airspace, the number of people applying for a pilot's license continues to increase, and the role of simulation training in flight training is particularly prominent. However, most of the control stick longitudinal mechanisms of existing trainer flight simulators are simulated by dampers, which cannot provide a realistic force feedback process. Its disadvantages are: the range of torque change is small, and it cannot pro...

AI Technical Summary

Problems solved by technology

However, most of the longitudinal mechanisms of the control stick of the existing trainer flight simulators are simulated by dampers, which cannot provide a realistic force feedback process.

Its disadvantages are: the range of torque change is small, and it cannot provide a complete control process; the change of torque is discontinuous, so that the pilots have to correct the control habits on the real aircraft, resulting in a decline in training efficiency; Excessive, affecting flight safety; lack of analog elevator trim (zero moment point adjustment) process, can not reduce and eliminate pilot fatigue
