IHI has developed the domestic engines for the Ministry of Defense since the generation of the J3 in the 1960s as a coordinating manufacturer, and continued making an effort on the F3, XF5, and F7 engines, as well as the recent successful XF9-1 demonstrator engine for a next generation fighter. Our group has been responsible for the development of combustors for these various engines. Combustors for fighter engines, which necessitate high maneuverability, are required to have high combustion stability, while the need for better fuel consumption and lower environmental impact is increasing in response to the growing demand for commercial aircraft in recent years. In order to meet recent engines' needs, we have developed the innovative “cross jet swirler” type combustor, which can achieve both higher operational stability and environmental performance than the conventional RQL type combustor. By combining the swirler with various types of fuel nozzle the requirements of each engine system can be fulfilled. This paper describes the status of our development efforts for combustors for aircraft engines and the outlook for future research and development.
