民用飞机主导式结冰探测系统设计

飞机结冰会造成全机气动性能下降、飞行品质降级等一系列问题,对飞行安全造成极大的威胁。现代民用飞机普遍装备结冰探测器以应对飞行中的结冰问题。主导式结冰探测系统是一种新型的自动判断飞机是否进入结冰条件的飞机结冰探测系统,能够有效减少机组操作负担。首先对主导式结冰探测系统进行了详细的介绍,包括主导式结冰探测系统和传统咨询式结冰探测系统的区别、主导式结冰探测系统优势以及主导式结冰探测系统主要设计难点。然后阐述了基于磁致伸缩式结冰探测器的主导式结冰探测系统的设计方法,主要在于识别出结冰探测器无法探测的结冰条件,通过将结冰条件预设在防冰系统控制器中,来确保能够在所有结冰气象条件下及时开启防冰系统。

Primary ice detection system design of civil aircraft

Aircraft icing can cause a series of problems such as aerodynamic performance degradation and flight quality degradation of the whole aircraft, which will pose a great threat to flight safety. Modern civil aircraft are generally equipped with ice detectors to deal with the icing problem in flight. The primary ice detection system is a new type of aircraft detection system that can automatically judge whether the aircraft has entered the icing conditions, which can effectively reduce the operating burden of the crew. This paper first introduces the primary ice detection system in detail, including the differences between the primary ice detection system and the traditional advisory ice detection system, the advantages of the primary ice detection system and the main design difficulties of the primary ice detection system. Then the design method of the primary ice detection system based on the magnetostrictive ice detector was described. The main purpose is to identify the ice conditions that can not be detected by the ice detector. By presetting the ice conditions in the controller of the anti-ice system, the anti-ice system can be opened timely under all the ice conditions.
