| 内容記述 | The Scramaccelerator, a novel type of supersonic-combustion, tube-based launcher has been developed that can accelerate almost any mass to velocities of 3 to over 7 km/sec. This paper describes the technology demonstration of the concept by firing 120-g projectiles into a 38 mm barrel at 2.8 to 3.2 km/sec. The results from the technology demonstration are presented along with calculated performance of the demonstration tests. Critical test issues discussed include sabot separation, venting requirements, and test performance. The results, obtained during testing indicate projectile accelerations were achieved of approximately 5000 g. Hence, these tests demonstrate successful Scramaccelerator operation and acceleration at approximately 1.95 times the Chapman Jouguet detonation velocity, far greater than the 1.15 to 1.3 times previously demonstrated. In addition, the tests demonstrate hypersonic propulsion at Mach numbers above 8, acceleration at greater than 3 km/s, and system integration technology sufficient to accomplish this success. |
