A variable arm torque feedback adjustment device for a trainer

Abstract

The invention proposes a variable arm torque feedback adjustment device for a trainer, which includes a mechanical system and a control system of a driving rod and its connecting rod, a variable arm mechanism, a spring, a computer and a driving rod potentiometer. There are two sets of variable arm mechanisms, including motors, transmission wheels, gears, lead screws, lead screw brackets, sliders, position feedback multi-turn potentiometers and their mounting brackets. The motor drives the lead screw to rotate, changing the combined spring force arm, so that the spring force acting on the control stick matches the aircraft dynamic pressure data, thereby obtaining the corresponding longitudinal control force during flight, and simulating the relationship between the longitudinal control force and the rudder surface angle and aerodynamic relationship. With zero-moment point adjustment, the control stick can be controlled to stay at any longitudinal position, and the moment of the pilot's manipulation of the control stick is zero, and the control stick can be released to maintain the current state, reducing and eliminating driving fatigue. Realized high fidelity and stable smoothness of driving stick force simulation. The structure is simple, the reliability is high, and the training efficiency is improved.

Description

technical field [0001] 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 [0002] 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 provide a co...

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
