机载TAWS设备测试考核系统的设计与实现

Design and Implementation of Airborne TAWS Test and Assessment System

地形提示和告警系统能有效避免飞机可控撞地事故,对于保障飞行安全具有重要意义,为保证TAWS的实际装机使用,研制过程需要对其功能和性能进行完整的测试考核。在梳理适航规章和某型TAWS系统研制要求基础上,首先分析了系统测试考核需求,由此给出了测试考核系统总体框架;在设计测试考核系统所需的激励器基础上,搭建了测试考核环境,以实现对TAWS的功能和性能测试。通过测试考核系统与被测TAWS的对接和试验,验证了测试考核系统的有效性。

The Terrain Awareness and Warning System(TAWS)can effectively avoid the occurrence of Controlled Flight Into Terrain(CFIT)and greatly increase the safety of aircraft flight.During the development of TAWS,it has a very important meaning to test and assess TAWS.According to the airworthiness requirements and the development requirements of the target system,the requirements analysis for system test and assessment was completed,the overall framework of the test and evaluation system was given,the modules required for the test and evaluation system were designed,and the test and assessment environment for function and performance testing of TAWS was built.Through the connection and testing with the TAWS simulation platform,the effectiveness of the test and assessment system is verified.
