Abstract

Successful operation of future supersonic transport aircraft systems will require significant advances in combustion technology. The conditions of supersonic flight and high altitude impose severe strains on ignition reliability, stability, and overall combustion efficiency. Of particular interest is the attainment of combustion enhancement and relight at flight envelopes with low ambient temperature and pressure. This research program examines the feasibility of obtaining reliable relight of Jet A and other fuels by laser energy sources. Excimer laser pulses (193 and 248 nm) are used to photochemically dissociate fuel, oxidizer, or sensitizer molecules to produce chain-branching radicals, which initiate combustion.
