Abstract
A turbine ramjet engine is provided which has a ram pressure air duct shrouding the basic turbo-engine in an annular manner. When the ramjet operation is disconnected, this ram pressure air duct, while at the same time intake air is released into the basic engine, is blocked off with respect to the supply of ram pressure air. It is provided to unblock or block an intake-side air inflow cross-section of the basic engine by the axial adjustment of a drop-shaped body with respect to a flow divider. A ring slide is provided which is axially adjustable to always be opposite this body which blocks the ram pressure air duct when the inflow cross-section of the basic engine is unblocked and unblocks it when the inflow cross-section is blocked. In addition, the ram pressure air duct is to be widened in a multicornered manner in the upstream direction at the level of a blocking zone caused by a local overtravelling of countersurface of the mentioned body and the ring slide.
