ABSTRACT:
A ramjet powered missile having means for controlling the air inlet geometry for best efficiency at a given end-of-boost-take-over Mach number and for changing the inlet geometry for best efficiency at a higher Mach number for fuel economy and extended flight range comprising a first jetisonable air inlet formed of a plurality of removable lip sections held in place by connecting struts and pyrotechnic thrusters. The explosive charge of the thrusters when activated eject the lip sections and struts outward and clear of the missile thus providing a second inlet of a different geometry.
