Embodiment Construction

[0031] According to the invention and shown schematically in FIGS. Two vertical empennages 6 constitute. Wing 4 does not carry any engine, and vertical stabilizer 6 is arranged at the end of horizontal stabilizer 5 .

[0032] At the rear of the aircraft 1 are mounted two engines 7 with propellers arranged on the back of said aircraft, the axes L-L of the engines 7 being parallel to the longitudinal axis X-X. The engines 7 are supported by brackets 8 (see also FIGS. 4 and 5 ) and are placed side by side. From the rear side, each engine 7 comprises two counter-rotating thrust propellers 9, 10 of diameter D in a bluff shape. Two propellers 9 on the one hand, and two propellers 10 on the other hand, are arranged opposite each other with a spacing between them at least equal to 60 cm. Furthermore, a minimum distance d between the ends of the propellers 9 , 10 and said body 2 is at least equal to 10% of said diameter D .

[0033] With respect to the rear part 2R of the airframe ...

Abstract

Disclosed is an aircraft having a reduced environmental impact. According to the invention, this aircraft comprises at least one engine (7) having at least one propeller (9, 10) supported, at the rear, on the back of the aircraft with the propeller(s) that is / are arranged in line with the rear portion (2R) of the airframe forming a noise-deflecting barrier.

Description

technical field [0001] The invention relates to an aircraft with reduced environmental impact. Background technique [0002] Propulsion systems with propellers, such as turboprops with a single propeller or pusher propellers with contra-rotating propellers, are known to have better energy efficiency than turbine engines. [0003] However, at present most aircraft are driven by turbine engines which, on the one hand, consume a lot of fuel and, on the other hand, are a source of environmental pollution since they discharge into the atmosphere. [0004] Therefore, with regard to saving energy and environmental pollution, it would be more advantageous to equip an aircraft with a propulsion system with propellers instead of turbine engines. [0005] However, in operation, propulsion systems with propellers are even noisier than turbine engines, thus advantages in terms of energy savings and environmental pollution due to blowdown - which benefit from replacing turbine engines wi...
