PURPOSE:To make a flight possible to go beyond Mach Three in a stable way, by installing a suction port in position between a turbojet engine and a pipe, while insetting a check valve of the turbojet engine inside a nozzle. CONSTITUTION:A suction port 1 is installed in position between a turbojet engine 10 and a pipe 16 whereby suction efficiency in time of a takeoff is improves in a great measure. At above Mach Three, the turbojet engine is stopped, closing a check valve 4 and opening each of suction ports 1, 3 and a check valve 5 instead, and air intake takes place from a suction port 8. And, suction air in a ram jet engine 11 at a rearmost part is taken in from a suction port 9 with a suction port 7 and a check valve 8 both opened. In addition, in time of a landing, since a restart of the turbojet engine becomes necessitated, a restarting exhaust port 14 is therefore installed. With this constitution, a flight of more than Mach Three is thus attainable in a stable way and, what is more, excellent in economical efficiency. |
