Flight simulator system with persistent overload simulation capability

Abstract

The invention discloses a flight stimulator system with persistent overload simulation capability. The flight stimulator system comprises a flight stimulator and an overload component model, wherein the overload component model is stored in a PC (Personal Computer); the flight stimulator comprises a nacelle, a rolling frame, a spiral arm, a weight balancing block, a base assembly, a first drive assembly, a second drive assembly, a third drive assembly and a fourth drive assembly, wherein the spiral arm, the nacelle and the rolling frame form a moving manned centrifugal platform; the moving manned centrifugal platform is driven by a motor in the base assembly and is also driven by the first drive assembly, the second drive assembly, the third drive assembly and the fourth drive assembly torealize persistent and non-instantaneous overload. A control method of the flight stimulator system comprises the following steps of: operating the flight parameters output by each device in the cockpit by a trainee; then, processing the flight parameters through the overload component model to as to obtain control parameters required by three-axial overload; and finally, accurately simulating three-axial persistent overload on the trainee by controlling the angular velocity of the spiral arm and the roll angle and the pitch angle of the nacelle.

Description

technical field [0001] The present invention relates to a ground flight simulation system, more particularly, refers to a ground flight simulation system capable of simulating three axial continuous overloads generated during actual flight. Background technique [0002] Modern high-performance aircraft will generate very large overloads during maneuvers, which have a very large impact on human physiology. The characteristic of this overload is that the peak value is relatively large, and the maximum overload can reach 9g (g is the acceleration constant of gravity, 9.81m / s 2 ); overload loading is fast, and the growth rate can reach 6g / s; the duration of overload is also longer, which can last for several seconds and may appear repeatedly. This long-lasting and large overload seriously affects the pilot's sense of space and ability to judge the situation during air combat maneuvers. The pilot may experience short-term black vision, spatial positioning illusion and even loss ...

Problems solved by technology

[0005] The fixed base flight simulator has less restrictions on the volume and weight of the simulator because of its fixed platform, and its visual simulation and cockpit simulation (cockpit layout, sound effects, etc.) Low, but it does not have the ability to simulate overload, the trained pilot (trainee) has no motion input, and the reality of flight simulation is poor

[0006] At present, the motion base flight simulator generally adopts the Stewart six-degree-of-freedom mechanism (see: Stewart D. Aplatform with six degree-of-freedom. Proceedings of the Institute for Mechanical Engineering. 1965, 180: 371-386) as its motion platform, both It has visual simulation and limited instantaneous overload simulation capability (about 0.1g ~ 1.9g, g is the constant of gravity acceleration, 9.81m / s 2 ), has been widely used in the flight training of low-mobility aircraft such as civil aviation airliners, but when it is applied to the flight training of high-mobility aircraft, it is limited by the working range of its motion platform, and can only simulate the limited displacement changes and small angular acceleration changes of the aircraft. , and there is no continuous load simulation function, the fidelity of the simulator is not high, and the flight training effect is poor
