Abstract

Sonic flow past a non-lifting, slender body of revolution is investigated by the use of small disturbance theory. An approximation for the local Mach number distribution is used to linearize the transonic potential equation. Solutions for the velocity components, pressure distribution, and drag are obtained in terms of simple integrals involving the body geometry. An extension to other Mach numbers in the transonic range is given. The theoretical pressure distribution and drag are found to give good agreement with experimental data.
