8' X 6' TRANSONIC WIND TUNNEL TESTS ON A 0.7 SCALE MODEL OF A 6-1/2' ' UNGUIDED ROCKET

Abstract

Measurements of normal force and pitching moment were made on a 0.7 scale model of a 6-1/2 in. unguided rocket at Mach numbers from 0.4 to 1.24 in the 8 x 6 ft. transonic tunnel at Farnborough. The results are analyzed to show the movement of centre of pressure on the rocket and the effect of modifications to the nose and tail, designed to improve the stability. The results show that none of the modifications was successful in preventing a sudden forward movement of the centre of pressure at a Mach number of 0.95, although the movement was reduced by a bourrelet fitted to the tail.
