Abstract
A gas turbine engine power unit (10) comprising a gas turbine engine hot gas generator (10a), the exhaust efflux of which drives a turbine (20) having a power output shaft (22). The exhaust efflux from the turbine (20) is directed into a chamber (23) having two outlets (24,25) to atmosphere. The outlets (24,25) are provided with valves (26,28) which are operable to ensure that only one outlet (24,25) is open at a given time. The first outlet (24) contains a heat exchanger (15) whereas the second outlet (25) contains a further turbine (30). The further turbine (30) drives an air compressor (32) the output of which is directed to an air inlet (36) of the gas turbine engine (10a) in order to facilitate a boost in its output power.
