The valve means is adapted to be opened or closed so as to permit or prevent flow of air from the main air intake and through the conduit or conduits to the auxiliary engine. In the embodiment shown two gas turbine jet engines 12 are mounted side by side in the fuselage 11 of an aircraft each engine having an air intake 13 and a jet pipe 18. Two auxiliary gas turbine jet engines 14, 15 are associated with each main engine 12 as shown in Fig. 3 and each of the auxiliary engines is connected to the main air intake 13 by a duct 20 which is controlled by a valve 21, see Fig. 2. The exhaust duct of each of the auxiliary engines is connected to the exhaust duct of the associated main engine by a duct 17. At high supersonic speeds of the aircraft the valves 12 are maintained in the closed position so that the auxiliary engines are not operative, all the air in the intakes 13 passing to the main engines 12. At lower speeds the valves 21 are opened and the auxiliary engines are brought into operation. The auxiliary engine 15 may be replaced by an auxiliary engine 16 as indicated in broken lines, each engine 16 being arranged to move between a horizontal or a vertical position, the engine in the latter position serving to provide vertical lift forces. The main engines may be arranged to operate either as gas turbine jet engines or as ram jet engines; for example, they may be engines as disclosed in Specifications 971,222 and 971,223.
