摘要: Introduction S OME qualifications to the pretentious nature of title this Paper are in order. Research context is applied, i.e., it directed toward design and development devices. The devices air breathing propulsion systems, wherein supersonic combustion inherent or provides an adjunct benefit. Principal applications former manned hypersonic aircraft, transatmospheric accelerators, missiles. Typical examples latter external burning systems that sustain thrust reduce drag when used tandem with primary accelerator engines. This not at all representative complete body research on combustion. Instead, what presented primarily based material which writer has had either direct involvement a first-hand knowledge. It does do justice exemplary works many other investigators. Hopefully, somewhat rectified by extensive list references. reader encouraged consult these manuscripts obtain more balanced perspective. applied must be viewed from perspective engineer who charged expediting need tools. Exact physics have frequently been abandoned produce functional models. Much experimental verification upon models obtained facilities known imperfections respect duplication flight conditions. Moreover, compromises made analysis interpretation data, part due imperfect incomplete diagnostic instrumentation, limited understanding underlying physics. An example embodies deficiencies would model use integral techniques describe flow experiments conducted arc-heated tunnel.
