航空燃气涡轮发动机喘振分析

Surge Analysis of Aviation Gas Turbine Engine

航空燃气涡轮发动机是常用的现代武器装备动力装置,其具有机械结构复杂的特点。在实际应用中,由于外部工作环境极其恶劣,航空燃气涡轮发动机内部气路部件、旋转部件极易发生各种风险故障。而喘振则是航空燃气涡轮发动机在运行过程中出现频率较高的故障之一,其对整体航空燃气涡轮发动机安全运行造成了极大的威胁。文章根据航空燃气涡轮发动机喘振表现,对其发生原因进行了简单的分析,并提出了几点消除措施。

The aeronautical gas turbine engine is a common power device of modern weapon equipment, which has the characteristics of complex mechanical structure. In practical applications, due to the extremely harsh external working environment, aviation gasturbine engine internal gas path components, rotating parts are prone to a variety of risk failures. Surge is one of the most frequentfaults in the process of aeronautical gas turbine engine operation, which poses a great threat to the safe operation of the whole aeronautical gas turbine engine. Based on the surge performance of aeronautical gas turbine engine, this paper simply analyzes the causesof the surge and puts forward some eliminating measures.
