Advanced Subsonic Engine High Efficiency Combustor

Abstract:

Overall engine efficiency can be dramatically improved with a high 
inlet velocity, low pressure drop, high heat release rate combustor 
which reduces diffuser losses and combustor pressure drop losses, 
improves turbine nozzle performance, and minimizes size and weight. 
For natural gas fuel, PCI has demonstrated a novel catalytic 
combustor design with very low pressure drop, high inlet duct 
velocity, high turndown and stability, and low NOx at pressure. 
With appropriate design modifications for liquid jet fuel 
operation, this combustor design should be suitable for integration 
into the advanced subsonic gas turbine engine program. In the Phase 
I, the important design issues for conversion to liquid jet fuel 
will be addressed for proof-of-concept testing leading to high 
pressure combustor testing in a Phase II.

This proposal offers a high efficiency, low emissions subsonic 
combustor technology which has substantial attractiveness for 
NASA's advanced subsonic gas turbine engine program.
