Expressions for the velocity potential and the lift and moment are derived for thin, oscillating, arrowhead type wings with supersonic edges moving at a constant supersonic speed. The triangular wing and any of the series of wings obtained from it by cutting its rearward part so that the flow normal to the resulting trailing edges remains supersonic are included in the term arrowhead type. Explicit results for the lift and moment are given for the wings undergoing harmonic pitching and vertical oscillations.
