基于VxWorks的飞行器模飞测试方法研究

在传统飞行器综合测试中，特别是模飞测试中，通常侧重于电气系统的接口匹配性测试，但对飞行控制软件、飞行时序和控制参数的正确性考核不够充分，往往需要依赖半实物仿真试验来进行验证。为解决飞行器传统模飞测试中测试覆盖性不足、测试效率较低的问题，在某型飞行器的测试过程中，采用闭环实时仿真的设计思路，设计了一套基于VxWorks的飞行器模飞综合测试系统。结合某飞行器电气系统综合试验开展了设计验证工作，试验过程模拟了多种工况下的飞行轨迹，能够验证和覆盖所有飞行时序动作，所有硬件系统均能按照设计流程工作，各项技术指标能够满足设计要求。试验表明该方法能够有效提高对飞行控制软件和时序动作的测试覆盖性并能提高整个飞行器的测试效率。

Research on Flight Simulated Flight Method of Aircraft Based on VxWorks

In the traditional integrated test for aircraft, especially in the simulated flight test, engineers focus on the compatibility of interface in the electrical system. It''s not sufficient to test the contol software, flight time sequence and control parameter, all of verification heavily depend on hardware-in-loop test. In order to solve the insufficient test coverage and low test efficiency in traditional silulated flight test, Depending on the design concept of closed-loop and real time simulated flight, a new methos of integrated test based on VxWorks is introduced in an aircraft test. iVarious working conditions are simulated n a real vehicle flight test, the test veriry and cover all the time sequence, all the hardware system work perfect as designed and all the technical indicators meet the design requirements. It shows that the system is completely effective to improve the test covergage and test efficiency.
