发明摘要本发明提供一种孔内管式喷射器,它被改进得既可作为一个进入气流的平滑器/回流区的稳定器,又可作为一个简单的孔盖。这个管子可以这样的平移,以致在助推阶段,使它处在堵塞冲压发动机进气口的位置。在燃烧室和进气口之间,用O形环适当地密封。当助推用的固体推进剂产生的压力减弱时,进气口的空气压力迫使管子向喷射孔内移动,打开进气口。发明背景本发明涉及的是固体燃料冲压发动机,特别是复合式的孔内管式喷射器和孔盖。
Summary of the Invention The present invention provides an in-hole tube injector that has been modified to act both as a stabilizer for the smoother / recirculation zone into the airflow and as a simple hole cover. This tube can be translated in such a way that it is in the boost phase so that it blocks the ramjet inlet. Between the combustion chamber and the air inlet, seal properly with O-rings. As the pressure generated by the propellant propellant weakens, the air pressure at the air inlet forces the tube to move into the jet opening, opening the air inlet. BACKGROUND OF THE INVENTION The present invention relates to solid fuel ramjet engines, and in particular to composite borehole tube injectors and portholes.
