Abstract

The invention relates to a real-time fixed wing aircraft simulation system and a simulation method. The real-time fixed wing aircraft simulation system comprises a lower computer, a host computer, a ground station unit, an instrument unit, a vision unit and a parameter interface unit, wherein the lower computer is used for operating an aircraft model in a real-time embedded system, the host computer is used for compiling an aircraft model application program into the real-time embedded operation system and sending the compiled real-time embedded operation system to the lower computer, PID control parameters of the aircraft model are modified in real time, an operation state of the aircraft model is monitored, and the parameter interface unit is used for sending designated aircraft model parameters to the lower computer to realize real-time simulation of a designated fixed wing aircraft. Through the system and the method, a flight scene is simulated in real time, versatility of the aircraft simulation system is improved, complex programming and debugging are avoided, and simulation cost is reduced.

Description

technical field [0001] The invention relates to the field of fixed-wing aircraft simulation, in particular to a real-time simulation system and simulation method for a fixed-wing aircraft. Background technique [0002] Traditional aircraft design, production, flight test verification is a complicated and lengthy process, and the existing aircraft flight test technology risks and test costs are very high. [0003] The most basic method now is to carry out all-digital simulation to the designed aircraft model. The existing full-digital simulation has poor real-time performance and poor versatility. First of all, MATLAB / Simulink simulation technology is under-real-time or super-real-time. Because the aircraft model is too complex, digital simulation is generally under-real-time simulation, and the simulation time is extremely slow; secondly, traditional aircraft simulation technology is only applicable to a single type of aircraft. If the C language code of the aircraft model ...
