The variation of the rolling moment with sideslip and the variation of the derivative with aspect ratio and Mach number were investigated.

The variation of the yawing moment with sideslip and the variation of the stability derivative with aspect ratio and Mach number were investigated.

A method is presented for determining the rolling and yawing moments of swept-back wings in steady sideslip at supersonic speeds. The case treated in particular is that of a swept tapered wing with all edges subsonic.

An analysis of combined heat and mass transfer from a flat plate has been made in terms of Prandtl's simpified physical concept of the turbulent boundary layer. The results of the analysis show that tor conditioins of reasonably small heat and mass transfer, the ratio of the mass- and heat-transfer coefficients is dependent on the Reynolds number of the boundary layer, the Prandtl number of the medium of diffusion, and the Schmidt number of the diffusing fluid in the medium of diffusion. For the particular case of water evaporating into air, the ratio of mass-transfer coefficient to heat-transfer coefficient is found to be slightly greater than unity.

The variations of lift and pitching moment with sideslip in supersonic flow have been calculated for a representative gorup of plan forms. The variations of lift and pitching moment with aspect ratio and Mach number at zero sideslip were also investigated. The analysis was based on linearized potential theory and was applied to triangular, trapezoidal, rectangular, and swept-back plan forms without dihedral.
