Commercial aircraft, has fairing articulated with respect to propeller drive such that air stream blown by counter-rotative propellers is oriented with respect to axis of drive for controlling direction and depth of aircraft

摘要

#CMT# #/CMT# The aircraft has a propeller drive mounted on back of the aircraft and with an axis parallel to a longitudinal axis of a vertical median plane. The drive has counter-rotative propellers (8, 9) surrounded by a fairing (10). The fairing is articulated with respect to the drive such that an air stream blown by the propellers is oriented with respect to the former axis for controlling direction and depth of the aircraft. #CMT#USE : #/CMT# Commercial aircraft. #CMT#ADVANTAGE : #/CMT# The fairing permits to mask noise generated by the propellers in order to reduce the noise emitted by the drive toward the ground during take-off and landing of the aircraft. The fairing is articulated with respect to the drive such that the air stream blown by the propellers is oriented for controlling the aircraft in direction and depth, thus eliminating the need for rear tail empennages in order to reduce resistance to movement of the aircraft, and hence reducing fuel consumption in the aircraft and improving performances of the drive and the aircraft. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a rear schematic view of a rear part of an aircraft. 2R : Fuselage`s rear part 6 : Mast 7 : Extension 8, 9 : Counter-rotative propellers 10 : Fairing.
