某型燃气涡轮起动机空中起动调整试验

Adjustment Test on a Gas Turbine Starter in Altitude Starting

利用某型燃气涡轮起动机进行空中辅助起动发动机试验,以期突破其仅用于地面起动发动机的限制,扩展起动机及发动机的起动包线。试验中通过对起动机供油规律的不同方式调整,获得了一定的起动机空中起动调整规律,并保证了该型起动机在5 km及以下高度成功起动。本文的研究工作对于起动机设计、试验及发动机空中起动研究具有一定的工程实用价值。

Assisted altitude starting test with a gas turbine starter was carried out to overcome the limit to ground startup only, and to extend the starting envelope of the starter. The adjustment rule of the starter was obtained by adjusting the different fuel supply rules during the test, which ensure successful starting by the starter at and below 5 kilometers. The investigation in this paper is with engineering application value in starter design, test and altitude assisted starting of engine.
