Abstract
An aircraft having two aft mounted prop engines on opposite sides of the fuselage. The side surfaces of the fuselage adjacent to the propellers are contoured so that each has an inwardly and rearwarding slanting forward region, a substantially longitudinally aligned intermediate region which is adjacent to the propellers, and a rear region which slants inwardly and rearwardly to an end closure location. This configuration results in a more uniform flow pattern into the propellers.
