Abstract
Although the APU combustors were developed successfully, it could face many unexpected hardships in an engine or a system operating under the severe environments. But, it is not easy to change the combustion field or combustor structure at the engine/system development stage. So we must suggest practical ways to optimize the value quantitatively by engine test and flow analysis, and verify those by the cyclic test. This paper describes reverse-annular type combustor troubleshooting processes for verifying and settling of the problems and issues occurred in various engine and system operation tests by experiment and analysis.
