Abstract: If the aircraft engine dies out during flight a reliable restarting ability must be provided.This is one of important function of engine to ensure flight safety. In this paper, the experimental techniques of restarting of turbojet engine in flight are described.Based on the experimental results and measurement data under the condition of windmill, the transient curves of the dynamic parameters and temperature at the restarting process are presented. The experimental results are of practical use in increasing ignition altitude and solving restarting testing problem in flight.
