Abstract: A propulsion system for an aircraft 10 comprises a plurality of main propulsion engines 14 which are mounted on the wings 16 of the aircraft 10 and which in operation provide a thrust to propel the aircraft 10 forward. An at least one further power plant, 18 (or 24), facilitates braking of the aircraft 10 and is mounted on the aircraft fuselage 12 remote from the main propulsion engines 14 in such a way as to cause insignificant drag during cruise. Use of additional power plants 18 (24), remote from the main propulsion engines 14, to provide the thrust necessary to effect braking of the aircraft 10 eliminates the need to provide thrust reversers on the main propulsion engines 14. This eliminates constraints imposed on the design of the engine and cowling of the main propulsion engines 14. The additional power plants may be rocket motors or gas turbine engines. The additional power plants 18 may be mounted on the inner face of rear fuselage doors 20 which, when extended to allow operation of the power plants, themselves form air brakes. Power plants (24) may serve as auxiliary power units and may selectively provide forward thrust for propulsion or reverse thrust for braking. <IMAGE>
