Abstract
DRDC Suffield has been studying the feasibility of hypersonic propulsion based on a standing detonation wave in the throat of a hollow projectile. Past numerical simulations have shown that a stable detonation wave can be established with the appropriate selection of throat diameter, inlet angle and combustible mixture. A 155-mm howitzer gun facility has been built to fire hollow projectiles into long plastic bags containing a pre-mixed acetylene-air mixtures. The muzzle velocity of the projectiles is approximately 2000 m/s. During the first round of firings, the aluminium projectiles failed to survive the loads during launch. This report details a new titanium projectile design that is sufficiently strong to survive the gun launch. In this contract, a number of powder charges of the ‘spaced charge array’ design were manufactured and titanium bar stock was procured in preparation for manufacturing hollow titanium projectiles.
