A vector study of linearized supersonic flow applications to nonplanar problems
Year: 1953
Abstract: A vector study of the partial-differential equation of steady linearized supersonic flow is presented. General expressions, which relate the velocity potential in the stream to the conditions on the disturbing surfaces, are derived. In connection with these general expressions the concept of the finite part of an integral is discussed.
A discussion of problems with planar bodies is given and the conditions for the solutions to be unique are investigated.
Problems concerning nonplanar systems are investigated, and methods are derived for the solution of some simple nonplanar bodies. The surfaces pressure distribution and the damping in roll are found for rolling tails consisting of four, six, and eight rectangular fins for the Mach number range where the region of interference between adjacent fins does not affect the fin tips.
