The stabilizing device () comprises auxiliary stabilizers () which are mounted on the horizontal tailplane () of the aircraft and which generate a lateral stabilizing effect when brought into a deployed position.

Method and device for the lateral stabilization of an aircraft

An aircraft with reduced environmental impact includes two turboprop engines mounted on the back of the aircraft at the rear thereof, and one acoustic masking device per turboprop engine. The acoustic masking device includes a masking element, such as a flap, which can move between a position in which it is retracted into the wing, and a position in which it is extended toward the rear of the wing. In the extended position, the flap intercepts the noise area generated toward the front by the turboprop engine, so as to reduce the perception of noise on the ground.

Aircraft with reduced environmental impact

An aircraft having a propeller engine mounted at the rear of the aircraft, on the back thereof, such that the axis of the engine is parallel to the longitudinal axis of the aircraft. The aircraft has a cell, the rear part of which comprises a horizontal empennage and two vertical empennages, positioned one at each end of said horizontal empennage. The propeller is positioned vertically in line with the rear part of the cell, and the rear part of the cell forms a lateral and downward barrier, on each side of a plane of the propeller, that screens an acoustic intensity equal to approximately&#x2212;5 dB with respect to a maximum acoustic intensity emitted by the engine.

Aircraft having a reduced environmental impact

An aircraft having reduced environmental impact includes at least one engine with at least one propeller carried, at the rear, on the top of the aircraft with the propeller(s) located in vertical alignment with the rear part of a noise barrier cell and the rear face of a burst zone situated forward of the central part of an empennage box.

Aircraft having reduced environmental impact

An aircraft with reduced environmental impact includes a turboprop, having two contra-rotating propellers, disposed on the rear portion on the back of the aircraft's fuselage so that the interaction noise of the propellers is masked, in the forward direction, by the wings and, in the rearward direction, by the aircraft's horizontal stabilizer.
