A 422 bus flight control test system for solid-liquid powered aircraft

Abstract

The invention discloses a 422 bus solid-liquid power aircraft flying control testing system. The 422 bus solid-liquid power aircraft flying control testing system comprises a main control testing platform, a portable measurement and control box, a flying control computer, an emulation computer and an interface machine; the main control testing platform provides a human-computer interaction interface and sends a testing command to a flying control computer; the portable measurement and control box outputs the testing command to the flying control computer after performing isolation transferring on the testing command signal to achieve flying control computer power supply, analog acquisition output and switching value signal input and output channel functions; the flying control computer performs sub-system testing and control to perform flying control algorithm resolving and generate into rudder deflection control quantity; the emulation computer simulates the aircraft to perform model real-time resolving; the interface machine perform data fusion and sending. The 422 bus solid-liquid power aircraft flying control testing system can achieve full-system semi-real-object testing, comprehensive monitoring of bus information, real-time storage and display of data, obtains possible conditions during flying to examine in advance and lays foundation for smooth execution of flight tests.

Description

technical field [0001] The invention belongs to the technical field of ground semi-physical simulation testing, and in particular relates to a 422-bus solid-liquid power aircraft flight control testing system. Background technique [0002] The solid-liquid power aircraft is a new type of aircraft that uses a solid-liquid power engine as a power device and has the characteristics of adjustable thrust and multiple starts. Compared with solid-powered engines, it can realize thrust adjustment, work for a long time, and start multiple times, and the combustion products do not pollute the environment. Compared with liquid-powered engines, it has simple structure, convenient operation, and low cost. Therefore, in the development of a new generation of aircraft power systems, solid-liquid power engines have greater advantages. Before the flight test of the solid-liquid powered aircraft, the performance and safety of each system of the aircraft must be tested, especially the semi-ph...

Problems solved by technology

[0003] The flight control computer program is developed by the underlying function and C language, and lacks a friendly interface. There is a black box effect in the interaction between it and the integrated navigation system, rudder system and electrical system. The operator cannot intuitively obtain real-time feedback results, and the feedback results unable to record
