The method of matching the joint work of the auxiliary power unit and turbostarter and determining the start time of the gas turbine engine

摘要

The paper describes the methodology developed by the authors for matching the working process of the auxiliary power unit and the air turbine used when starting the engine. This technique is used to determine the possibility of starting a gas turbine engine, as well as to calculate its time and main parameters under all operating conditions (including in flight) and to select new auxiliary power units or an air turbine for an existing system. The developed technique considers structural, strength, operational and other limitations. The results were implemented as a computer program.
