Aero-engine ground starting performance at non-standard atmosphere

  • In order to gain the influences of the atmosphere condition on aero-engine starting characteristics, the output power of air turbine starter and ideal starting process at standard atmosphere were analyzed, and the diversities of ground starting performance at non-standard atmosphere were described, e.g.: differences of ignition time, start time and exhaust gas temperature. Besides, with use of constant acceleration method, the starting process was simulated. Based on grounding test conditions, test data was summarized. The ignition and breaking-up time was prolonged with the temperature drop or rise. Comparing the start time below or above 293.15K,it is 3s shorter in hot days than in cold days, so the results meet the theory analysis well.
