民用飞机RAT发电机自然结冰环境飞行试验研究

为了检验某型飞机RAT发电机在自然结冰环境下能否正常释放和供电,对该RAT发电机自然结冰试飞进行研究。首先,阐述RAT发电机进行自然结冰试飞的原因、目的以及民用航空标准对自然结冰环境的要求;其次,介绍RAT发电机自然结冰的试飞方法;最后,对试飞结果进行分析。结果表明:RAT发电机自然结冰环境条件满足适航规章要求,能够在可预期的自然结冰环境下实现手动释放功能且供电功能正常。

Research of Flight Test in Natural Icing Environment for The Civil Aircraft RAT Generator

This paper analyzes and researches the RAT generator natural icing flight test of a type of domestic aircraft in its development process. Firstly, this paper introduces the reason and purpose of the RAT generator natural icing flight test, and the civil aviation standards for natural icing environment. Secondly, the paper introduces the flight test method for RAT generator natural icing flight test. Finally, the test results are analyzed. The results show that RAT generator flight test of natural icing environmental condition meet airworthiness regulatory requirements, RAT generator manual release function can be realized in the foreseeable natural icing environmental condition, and the power supply function is normal.
