Abstract
An assessment of future aero engine technology has been made, both for the near term (1995) and the long term (2005), covering a wide spectrum of applications. The technology available in the 1995 time frame can be estimated fairly easily, and engines in service at that time are beginning their development cycle now or in the near future. Up to 1995 development will be evolutionary, with the biggest change being the development of Ultra High Bypass systems for long haul transports. By the year 2005 compound cycles and ceramics may be a reality for small engines, but the most significant change to be seen from the present will be a major reduction in the number of stages while maintaining pressure ratios at the present level or somewhat higher. It is likely that pressure ratios will not rise too much in the future, especially for fighter aircraft, but there will be some increase in turbine inlet temperature, achieved with a reduction in cooling air requirements.
