Abstract

The invention discloses a backup power test system for fly-by-wire control system test. A helicopter semi-physical simulation test system comprises a simulation management computer, a three-axis turntable connected with the simulation management computer, an avionics simulator connected with the simulation management computer, a flight control test bench connected with the avionics simulator, the three-axis turntable and a test bench frame, and a displacement sensor arranged on the test bench frame and connected with the simulation management computer. The helicopter semi-physical simulation test system of the application reflects the flight attitude more truly because of physical simulation added in flight attitude simulation.

Description

technical field [0001] The invention relates to the technical field of fly-by-wire flight control systems, in particular to a helicopter semi-physical object simulation test system. Background technique [0002] In the field of helicopters, hardware-in-the-loop simulation tests have been widely used. Various parameters in the flight process of the helicopter can be simulated through the hardware-in-the-loop simulation test, especially the parameters of the flight attitude are the most important. [0003] In the prior art, semi-physical physical simulation tests are used for simulation, so as to obtain various flight attitudes, angular velocities, and accelerations of the helicopter. Mathematics method is used for simulation, this method mainly adopts linear simulation method, but in actual flight, the flight attitude is usually nonlinear, therefore, the results of simulation using semi-physical simulation test in the past are distorted. [0004] Therefore, it is desirable ...
