Calculation of Higher Approximations for Two-Dimensional Compressible Flow by a Simplified Iteration Process
Abstract
The iteration equations for a simplified solution of the nonlinear compressible-flow equation are developed and applied to two profiles, the ellipse and the Kaplan section. Limitations imposed on the solutions by simplifications in the differential equation and the boundary conditions are discussed. The velocities near the midchord, the critical and potential limit free-stream Mach numbers, and the extent of isentropic supersonic regions are calculated to four approximations for the Kaplan section and to six approximations for the ellipse. The development of the iteration equations and the presentation of the results are made in conformity with the Karman transonic similarity law and comparisons are made with other solutions.
