Abstract
A jet engine includes a gas turbine, peripheral ramjet channels located oide the gas turbine and including burners wherein a gas circulation stream in the engine is subdivided over part of its length into a central turbojet stream which flows through the gas turbine, the peripheral ramjet channels and peripheral discharge channels terminating by flowing into a part of the gas circulation stream downstream of the turbine. A plurality of flaps are provided for opening and closing the central stream. A ring surrounds the central stream and extends in front of part of the peripheral discharge channels and ramjet channels. A motor is also provided for rotating the ring wherein the ring has a plurality of slots formed therein, the channels being arranged such that the slots successfully pass, during rotation of the ring in a continuous direction, in front of the discharge channels only, then in front of none of the channels and then in front of the ramjet channels only.
