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.
