Concurrent Research on High Gravity (g) Combustion with Enabling Materials

Abstract

A gas turbine combustor concept that uses high g-loading in the circumferential cavity is being tested at AFRL to provide the foundation for development of a low-emissions, ultra-compact, high performance combustion system for future military and commercial aircraft. This work comprises experimental testing and modeling and simulation of different high g-loaded combustion cavities. Initial tests indicate that, by using highly swirling flows, the combustor performance can be enhanced in the form of improved combustor efficiencies at reduced combustor length. Understanding the impact of high g-loading on the pollutant emissions, operability limits, and combustor durability are three major areas where the AFOSR program will progress the scientific understanding of the physical processes involved in this novel combustion system.
