Transport aircraft take-off and landing facilitating method, involves deploying retractable auxiliary air blowers, and modifying shapes of blowers between working and storage positions to retract blowers in limited volume such as wing

摘要

#CMT# #/CMT# The method involves deploying retractable auxiliary air blowers that are actuated by a main jet engine (11) having a high by-pass ratio, where the engine is placed below a wing (4). Shapes of the blowers are modified between working position and storage position of the blowers in order to retract the blowers in a limited volume such as wing. A rotor of the blowers is actuated by a turbine that receives a compressed air from a compressor of the main engine, where the air is heated by an auxiliary combustion chamber. #CMT#USE : #/CMT# Method for facilitating take-off and landing of a transport aircraft (claimed). #CMT#ADVANTAGE : #/CMT# The shapes of the retractable auxiliary air blowers are modified between the working position and the storage position of the blowers in order to retract the blowers in the limited volume such as wing, thus reducing the fuel consumption of the aircraft, and the noise level during take-off and landing of the aircraft, while improving the yield of the aircraft in an economical manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial front view of a transport aircraft illustrating a main jet engine fixed below a wing, and an auxiliary air blower that is retracted in three parts and not folded in the wing. 1 : Cylindrical fuselage 4 : Wing 11 : Main jet engine 21 : Upstream air inlet duct 41 : Downstream air inlet duct.
