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. A new titanium projectile has been designed that is sufficiently strong to survive the gun launch. In this contract, four complete titanium projectile assemblies have been manufactured. Custom mandrels and specialized tooling were required in order to machine these thin-walled titanium items.
