Results of Tests of determine the Effect of a Conical Windshield on the Drag of a Bluff Body at Supersonic Speeds

Abstract

Tests were conducted on bluff body using three different nose shapes: sharp, blunt, and conical windshield. rocket-propelled test bodies consisted of identical wooden after bodies and fins with various nose shapes attached. Experimental data were obtained by launching body at angle 75 degrees to horizontal and determining its velocity along flight path using CW doppler radar. At March number of 1.37, conical windshield and sharp nose bodies had respective drag coefficients 6 and 27% lower than blunt nose body.
