Performance Tests with the WES 4-ft Diameter Vertical Gas Gun

摘要

Twenty-two tests have been conducted with the WES 4-ft Diameter Vertical Gas Gun.These tests were conducted over the entire operating range of the gun (0 to 2,070 kPa). The projectile velocity on these tests varied from 5.4 to 71 m/sec. The measured velocities were on average, about 90 percent of the values predicted by the mathematical model of the gun's performance. The accuracy of the velocity
