吸气式超声速巡航导弹进气道现状及发展趋势

ir-breathing supersonic cruise missile is one importance part of missile in the future. The inlet types and layout on missile is reviewed in this paper. Combined with air-breathing supersonic cruise missile development, designed Ramjet inlet will be incorporated in missile, at the same time, meet with long-rang, stealth, wide flight range, maneuverability and all-purpose missile. Designed high performance inlet with fixed-geometry, designed conventional inlet based on unconventional shape, selfstarted/restarted technology of inlet with fixed-geometry, designed variable geometry inlet and coupled poly-inlets etc. are the key issues of ramjet inlet. Based on current position of our country, the advice of inlet foundation research are bring forward which include establishing database of the inlet performance, investigating realizable flow control, designing variable geometry inlet and unconventional inlet.
