FIELD: transport.
SUBSTANCE: invention relates to aircraft with reduced environmental effects. Aircraft has lengthwise axis and comprises at least one engine furnished with at least one propeller arranged behind the engine. Engine lengthwise axis is primarily parallel to that of aircraft. Airframe tail part comprises tail unit torsion box supporting horizontal tail, and two vertical tails, each arranged on horizontal tail end. Propeller is arranged vertically on one straight line with airframe tail part for the latter to make anti-noise barrier with respect to at least engine noise directed downward. Engine is arranged in airframe tail part on its top to have rear boundary of destruction area in front of tail unit torsion box central part. Horizontal tail has sweep forward.
EFFECT: reduced environmental effects.
