Abstract:

Plenum Chamber burning PCB continues as one of the most viable options for vertical take-off and landing aircraft with a supersonic capability. Assessments of the future thrust requirements for such aircraft show that higher levels of temperature rise than previously demonstrated will be required, coupled with the ability to operate efficiently over a wide range of fuel air ratios in an expanded flight envelope. This paper describes the research and development programmes that were carried out on model and full size rigs to design and evaluate advanced concepts to meet the anticipated requirements. The system characteristics which were evaluated include pressure loss, ignition, efficiency, thermal integrity and velocity profiles at nozzle exit under non-combusting dry and combusting conditions. The successful achievement of the target levels of performance on the rig will now be followed by further demonstrations on the full engine.
