Wind-tunnel tested of a jet-engine nacelle on a semi span wing having the leading edge swept back 37.25° were made to determine the effects of the nacelle on the aerodynamic characteristics of the wing. The wing had an aspect ratio of 6.04 and the tip chord was half the root chord. The nacelle was mounted in three positions: centrally and low on the wing at the 31-percent—semispan station and centrally at the wing tip,nIn comparison with the force characteristics of the wing alone the addition of the nacelle to the wing in each position resulted in favorable interference on the maximum lift and pitching-moment characteristics and in a small increase in drag.
