SURFACE PRESSURE DATA ON A SERIES OF ANALYTIC FOREBODIES AT MACH NUMBERS FROM 1.70 TO 4.50 AND COMBINED ANGLES OF ATTACK AND SIDESLIP

摘要

Tabulated surface pressure data for a series of four forebodies which have analytically defined cross sections and which are based on a parabolic-arc profile having a 20° half-angle at the nose are presented without analysis. The first forebody has a circular cross section, and the second has a cross section which is an ellipse with an axis ratio of 2/1. The third has a cross section defined by a lobed analytic curve. The fourth forebody has cross sections which develop smoothly from circular at the pointed nose through the lobed analytic curve and back to circular at the aft end. The data generally cover angles of attack from -5° to 20° at angles of sideslip from 0° to 5° for Mach numbers of 1.70, 2.50, 3.95, and 4.50 at a constant Reynolds number.
