Abstract

In an engine (10) driving a pair of aft located, contra-rotating prop-fan propellors (28, 30) through a reduction gear-box (32), the engine exhaust gases are taken out through a duct (36) located in a strut (14), and a nozzle (38) adjacent a surface of an aircraft (12). The exhaust gas are fully expanded and are arranged to improve the flow over the aircraft fuselage. The strut wake can be reduced by a bleed of compressor air or exhaust gases through outlets (40). <IMAGE>
