Wind Tunnel Tests on a Nonaxisymmetric Projectile Shape at Mach Numbers 2.5 to 6.0.
Abstract
Wing tunnel tests on spinning nonaxisymmetric projectile configurations at Mach numbers of 2.5 to 6.0 are reported. The projectile shapes are ogive- cylinder bodies which have been modified by machining three forward facing surfaces and three rearward facing surfaces on the projectile. The machined surfaces are twisted at a rate corresponding to a typical rifling twist. The forward facing surfaces produce a helical or corkscrew type effect and the rearward surfaces form a nonconical boattail and a triangular base. The objective of the test program was to study shapes which have improved stability characteristics which require less gyroscopic stabilization. A more slender, longer L/d projectile can then be flown which has lower drag and shorter time of flight to a moving target.
