Combustion in Solid Fuel Ramjets
Abstract
A comprehensive experimental/modeling effort is proposed to enhance understanding of solid fuel ramjet combustion. The experimental facility will be complimentary in scale to existing rigs operated at Naval Air Warfare Center at China Lake and will incorporate high capacity heated air system for mimicking flight enthalpies without vitiation. The test article will also include provisions for bypass of some of the airflow around the main solid fuel grain. The facility will also be capable of running in coldflow mode to rapidly assess unsteady flow reattachment downstream of flameholding features. Advanced diagnostics such as high speed particle image velocimetry and real time ultrasonic measurement of fuel regression will be employed. Both conventional and non-conventional flameholder configurations will be considered. Companion modeling efforts will be conducted to provide enhanced understanding of experimental data and to guide future testing efforts. High resolutions computations with detailed chemistry and surface regression will be conducted. Lower order models suitable for incorporation into ballistics tools will also be provided. The team conducting the work will involve two faculty, two graduate students and a fraction of a research scientist who will aid development of the computational model.
