Method for establishing halt instruction curve of host computer of centrifugal dynamic flight simulator

Abstract

The invention discloses a method for establishing a halt instruction curve of a host computer of a centrifugal dynamic flight simulator. The method comprises the following steps of: establishing an initial curve, wherein a rotating speed of the hose computer before the starting of the halting moment is indicated by a first segment, a target halting rotating speed after the ending of the halting moment is indicated by a third segment and an oblique line segment connected between the first segment and the third segment is arranged as a second segment; redefining the three segments and adding or reducing two segments at corners; and correcting the initial curve, thereby acquiring an optimized halt instruction curve. The method disclosed by the invention is suitable for the centrifugal dynamic flight simulator, can be utilized to stably and quickly halt at any moment and under any states and can be used for effectively solving the problems of vibration and shocking of the host computer in the halting process of the centrifugal dynamic flight simulator so as to guarantee the safety of the pilot.

Description

technical field [0001] The invention relates to a shutdown method of a centrifugal dynamic flight simulator, in particular to a method for making a shutdown instruction curve of a centrifugal dynamic flight simulator main engine. Background technique [0002] With the development of high-performance fighters, the abnormal speed, acceleration and angular motion stimulation produced by their high-speed and large maneuvering characteristics will seriously affect the physiological and psychological state of the pilots, and easily cause loss of consciousness (G-LOC), spatial orientation disorder (SD ), etc., threatening flight safety. The field of aviation medicine believes that carrying out manned centrifuge training is an indispensable and important measure to improve the pilot's physical adaptability in the air and ensure flight safety, and it should be regarded as an indispensable, safe and economical training item for pilot training.

AI Technical Summary

Problems solved by technology

As an important function of the centrifugal dynamic flight simulator, the shutdown function is also the result of the joint action of the main engine speed command, pitch angle command and roll angle command. Direct shutdown (directly give the command as a shutdown command to force the manned centrifuge to stop quickly), lacks control over the shutdown process, and the command has a sudden change point, which will inevitably cause vibration and shock of the main engine, and may cause the load change rate to exceed the pilot's ability. The maximum rate of change of load sustained, causing injury to the pilot

[0005] The traditional centrifugal dynamic flight simulator main engine shutdown command generally adopts a curve method, which avoids the problems of direct shutdown, but the formation of the curve is generally a preset form, and there is no real-time correction mechanism, so its stability is still insufficient and cannot be realized. The purpose of stable, smooth and fast shutdown at any time and in any state
