摘要:

本文介绍DDK-1自动点火起动装置在某高空台模拟高空情况下,起动与S进气道匹配的某涡喷发动机的试验情况.DDK-1自动点火起动装置使该发动机在空中模拟状态下从点火起动到加速完全实现自动化.这是在国内涡喷发动机高空模拟试验中首次应用.该系统具有实际应用价值.

Abstract:

In this paper, an application of automatic ignitor DDK-1 in tests of turbojet with a s-shape air inlet under simulated altitude condition are intro-ducted. Automatic ignitor DDK-1 is useful for turbojet test in simulated altitude condition. Due to the use of automatic ignitor DDK-1, the process of engine test under high altitude simulation condition from igniting and starting to speeding up is completely automazited. It is the first application of this ignitor to turbojet test under simulated altitude condition in China,and available in pratical applications.
