ABSTRACT:
Turboramjet engine having a variable air intake, a ram air duct annularly enveloping the basic turbojet engine, and shutoff devices with which the ram air duct is energized with air when the basic turbojet engine is shut off and with which the basic turbojet engine is energized with air when the ram air duct is shut off. An air tract communicates with the air intake on a tubular duct carried axially on the basic turbojet engine and expands to an annular inlet section to the ram air duct. The shutoff devices are associated at least on the inlet side with quadrilateral sections of the tubular duct. As shutoff means for the inlet flow, use is made of an axially adjustable and internally swept sleeve valve and at least one flap that can be pivoted against a partial inlet area of the inlet section, which flap seals off the sleeve valve in lid-fashion when the inlet section is in a jointly exposed position.
