Theoretical Analysis of the Flow Field Over a Family of Ogive Bodies.

Abstract

Several analytical methods were employed to calculate the flow fields about spherically blunted ogives from Mach numbers of zero to 4.5. The methods used were the Dougles Herman (a panel method) with compressibility correction, the South potential flow program (RAXBOD) and the three dimensional method of characteristics. Bluntnesses varied from zero (sharp nosed) to one (hemispherical nose) and the finess ratio varied from 0.5 to 4.0. Where the computer codes being used permitted, the flow fields were calculated for 2 deg and 0 deg angle of attack; in all other cases only 0 deg angle of attack was considered. Data are presented for body surface distributions of pressure and Mach number and for wave drag. (Author)
