A summary and analysis has been made of results obtained in a systematic research program concerned with the effects of wing sweep, aspect ratio, taper ratio, and dihedral on the rolling moment due to sideslip characteristics of wing-fuselage configurations up to Mach numbers of about 0.95. Other test results are presented to show trends of rolling moment due to sideslip with Mach number for a few wings in the transonic and supersonic speed range.

A method which has previously been presented for the estimation of the low-speed stability derivatives of swept wings is modified to yield approximate corrections for the first-order three-dimensional effects of compressible flow in the subsonic region. Corrections are presented in chart for for several aspect ratios and angles of sweep. Lift-curve slopes and values of damping roll are compared with those obtained by use of a generally accepted method and are discussed in relation to unpublished data.
