Abstract

The invention discloses a flight quality semi-physical simulation test method, and belongs to the technical field of flight control. The flight quality semi-physical simulation test method comprises the steps that one, a simulation management system accepts an attitude response signal from a flight control system, performs dynamic mathematic model calculation and sends a calculation result to a bus signal simulation system, the bus signal simulation system converts the calculation result into a bus simulation signal and transmits the bus simulation signal to the flight control system, and theflight control system performs a corresponding attitude response according to the collected bus simulation signal and transmits the attitude response to the simulation management system; two, flight quality semi-physical simulation test units are formulated; three, a flight quality semi-physical simulation test is performed in allusion to the established simulation test units, and signal parameters of each test unit are observed and recorded at the same time; and four, a data analysis and quality assessment system performs grade assessment on each test unit according to the signal parameters of each test unit. The flight quality semi-physical simulation test method shortens the argumentation process of model development, reduces uncertain factors in the development process and acceleratesthe development progress.

Description

technical field [0001] The invention belongs to the technical field of flight control, and in particular relates to a flight quality semi-physical simulation test method. Background technique [0002] The function and performance of the flight control system directly affect the overall performance index and flight safety of the helicopter, so the flight control system needs to be fully and fully tested and verified on the ground, and the semi-physical simulation of the flight quality of the flight control system is the core of it component. At present, there is no relevant flight quality semi-physical simulation test technology in the field of helicopters in China, so a flight control system flight quality semi-physical simulation technology is needed to ensure that the performance indicators of the helicopter meet the technical requirements. Contents of the invention [0003] Purpose of the present invention: in order to solve the above problems, the present invention pr...
