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.

An aircraft comprising: (a) a fuselage having a longitudinal center axis, a forward portion, an intermediate main portion, and a rear portion, said rear portion comprising a forward section, a rear section with an end closure location, and an intermediate section, (b) first and second engines mounted adjacent to an exterior surface of said rear section, said engines having first and second enclosed propeller means at first and second propeller locations, said propeller means being arranged to rotate about first and second propeller axes, respectively, with each propeller axis having a substantial alignment component parallel to said longitudinal axis, (c) the rear portion of the fuselage having first and second exterior, longitudinally extending surface portions, said first surface portion having a first forward surface region extending longitudinally along said forward section, a first intermediate surface region extending along said intermediate section adjacent to said first propeller means, and a first rear surface region extending along said rear section, said second surface portion having a second forward surface region extending longitudinally along said forward section, a second intermediate surface region extending along said intermediate section adjacent to said second propeller means, and a second rear surface region extending along said rear section, (d) said rear fuselage portion being characterized in that the forward region of each surface portion slants rearwardly and inwardly toward said longitudinal center axis at a relatively greater inward and rearward slant relative to said longitudinal axis and curves concavely to join to its related intermediate region which has less inward and rearward slant with respect to said longitudinal center axis relative to its related forward surface region, each intermediate region joining to its related rear region in a convex curve with each rear region slanting rearwardly and inwardly to said closure location.
