#CMT# #/CMT# The method involves adjusting fixed supersonic turbojet engines (21, 22) with a low dilution rate, left and right retractable or fixed subsonic turbojet engines (11, 12) with a low dilution rate, a deployed left scoop (41), a deployed right scoop and additional left and right retractable air blowers (31, 32), based on different flight phases such as supersonic and subsonic phases. The left and right air blowers are actuated by drawing of energy on the engines (11, 12). #CMT#USE : #/CMT# Method for reducing noise and fuel consumption of a cargo aircraft e.g. silent supersonic and subsonic cargo aircrafts, during take-off and landing of the aircraft (all claimed), in industrial field. #CMT#ADVANTAGE : #/CMT# The method permits to displace and store heavy turbojet engines, in a simple manner, and to reduce noise and fuel consumption of a supersonic cargo aircraft during take-off and landing of the aircraft, in an efficient manner, while improving efficiency of the engines of the aircraft. The method permits to make flying of the aircraft in a subsonic flight phase, in an inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional front view of an aircraft with subsonic and supersonic turbojet engines having scoops and retracted additional air blowers, at left and right, respectively. 1 : Fuselage 11 : Left retractable or fixed subsonic turbojet engine 12 : Right retractable or fixed subsonic turbojet engine 21, 22 : Fixed supersonic turbojet engines 31 : Additional left retractable air blower 32 : Additional right retractable air blower 41 : Deployed left scoop. |
