ABSTRACT:
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.
