Abstract
A twin-engined VTOL/STOL aircraft comprising a rearwardly bifurcated fuselage 10 is proposed which in the event of failure of one engine 20 will allow the other engine 20 to produce a thrust which is not assymetric relative to the longitudinal axis of the aircraft. The fuselage 10 comprises a central front nose portion 11 and two side mounted engine nacelles 13, 14 which extend rearwardly to define spaced tail booms 15, 16. The engines 20 are preferably by-pass gas turbine engines in which the turbine exhaust gases are discharged through one or more nozzles 28 to the rear of the nose portion 11 between the tail booms 15, 16 on the center-line of the aircraft. The by-pass air is discharged through one or more nozzles 27 adjacent the longitudinal center-line of the aircraft. The nozzles 27, 28 are either swivellable, or other devices 34, are provided to vary the direction of thrust from the nozzles.
