| Abstract: | Expressions based on linearized supersonic potential theory are given for the total lift and moment coefficients of thin arrowhead wings as treated herein includes all pointed-tip wings; the delta plan form with an uswept trailing edge is a special case. A restriction is that the component of flow normal to the trailing edge must be supersonic or sonic. The total coefficients have been obtained by integration of the section coefficients given in NACA Report 1099 for the subsonic-leading-edge wing (to the fifth power of the frequency) and in NACA Technical Note 2494 for the supersonic-leading-edge wing (to the third power of the frequency). The accuracy of these expressions extends to sufficiently high frequencies to make them potentially useful in flutter applications. |
