Flight environment simulation system

Abstract

The invention provides a flight environment simulation system. The system comprises a core calculating module, a signal acquisition module and an input / output module, wherein the core calculating module is used to calculate simulation data; the signal acquisition module is used to provide the data signals of an external device to the core calculating module; the signal acquisition module containsan avionics system test-bed signal acquisition device and an engine control test-bed signal acquisition device and / or an iron-bird test-bed signal acquisition device; and the input / output module is used to input instructions in the core calculating module or output the simulation data calculated by the core calculating module. By adopting the system of the invention, the system can be combined with the real device or high-accuracy simulation device of the aircraft selectively according to the test requirement, thus real data signals or data signals which are very close to the real data signals can be utilized to simulate a special flight environment and the accuracy of the flight environment simulation system can be effectively increased.

Description

Technical field [0001] The invention relates to the field of computer simulation, in particular to an improved flight environment simulation system. Background technique [0002] In the process of research and development of aircraft, it is often necessary to perform performance tests on various systems of the aircraft to verify whether it can meet the design requirements, and whether it has reliability and stability. For safety reasons, these tests must be completed on the ground before the aircraft test flight, rather than in the air after the aircraft is assembled. Therefore, during these tests, it is necessary to use a flight environment simulation system to simulate the flight environment of the aircraft, and provide various simulation data to the system to be tested, so that even in the test room, the aircraft can be Test the performance in various environments. [0003] The traditional flight simulation system adopts pure software simulation mode, that is, all simulation d...

AI Technical Summary

Problems solved by technology

[0005] However, the shortcomings of the above-mentioned flight simulation system are still very obvious

Since various flight environment sub-models of the built-in general-purpose aircraft are used as the source of simulation data, there is a large gap between the data obtained by these simulations and the real data of the specific aircraft for which the simulation effect is greatly reduced. The effectiveness and reliability of system testing has buried security risks

In the subsequent test flight or actual use, the real data generated by the aircraft may far exceed the tested safety range, resulting in equipment failure
