The simulation training system disclosed by the invention can vividly simulate the experiment scene of the model for a six-degree of freedom unconstrained flight in the low-speed wind tunnel experiment section, and the problem of cooperative control training simultaneously by multiple pilots can be solved.

Description

technical field [0001] The invention belongs to the field of flight simulation, in particular to a ground simulation training system for low-speed wind tunnel model flight experiments. Background technique [0002] In the large-scale low-speed wind tunnel model flight experiment, the control and response of the model aircraft have the following characteristics: (1) Due to the use of a dynamic similar scale model, compared with the full-scale real aircraft flight, the dynamic response speed of the model is the same as that of the full-scale real aircraft. Compared with the real machine, it is much faster; (2) In the wind tunnel experiment section, six degrees of freedom are flying, and the extremely limited movement space requires the pilot to quickly control the position of the model; (3) Since the pilot is located in the measurement and control room and controls the movement of the model remotely , the lack of perception of the acceleration of the aircraft motion, which to ...

AI Technical Summary

Problems solved by technology

For the training of such flight operators, the aircraft model is generally used to carry out flight control training in the air. This method not only has high risk, high cost, and long preparation time, but also the control environment and control feeling are not consistent with the wind tunnel model flight experiment scene. The control and response characteristics of the aircraft model are not consistent with the response of the model to be used in the experiment, and realistic training cannot be realized; while the current general flight simulators are all simulators driven by a single pilot, and it is impossible to realize the coordinated control training of three pilots. Moreover, the visual display is also a single viewing angle, which cannot simulate the different viewing angles seen by different pilots during the wind tunnel model flight test
