Starting of jet engine is required to ensure the engine to be rotated up to idle reliably and satisfactorily. The starting performance is modified based on the test to a flight evalution schedule of a sample engine. The measurement and the data acquisition for a small single spool engine are conducted on a sea-level test bench firstly.It is shown that as main fuel is ignited flame with temperature above 1250℃ occurs at blade tips, while the average exhaust gas temperature is 400-500℃. The mechanism and the criteria for overheating of turbine blade and hot hung during starting are presented in this paper .By using heat releasing ratio DTP as the criteria to measure the overheating, the effects of FAR,fuel droplet size, fuel evaporation constant and air density on it are also discussed.
