Abstract
A novel multi-lobe flame holder design concept was designed, fabricated, and tested under high vitiated air flow temperature conditions for Light-Off (LO)and Lean Blow Out (LBO) performance. The new novel flame holder concept clearly demonstrated an improved LO/LBO performance pver the conventional V-Gutter flame holder. A three-flame test rig which consisted of a gas-generator, spray bars, and test section was also designed and fabricated. The Phase-II efforts will focus on further development and demonstration of the multi-lobe flame holder concept and preparation of full size augmentor system for follow-up system testing and trnasitioning ii into turbine engine hardware. BENEFIT: The novel multi-lobe flame holder concept has already demonstrated a better LO and LBO performance than the conventional V-gutter flame holder. Such an LBO improvement will increase the static stability margin and allow the engine to operate at lower perssure with stable flame. This will enable widen the flight envelop and/or increase thrust for the same stability limit as that of the V-Gutter flame holders by reducing dry pressure losses. The novel concept is already being considered by an OEM of military turbine engines for transitioning it into one of their engines. This novel concept will also be of greate interest to Other OEMs to which it will be marketed at the end of Phase-II. b
