Lc. Chhabildas et al., AN IMPACT TECHNIQUE TO ACCELERATE FLIER PLATES TO VELOCITIES OVER 12 KM S/, International journal of impact engineering, 14(1-4), 1993, pp. 121-132
Very high pressure and acceleration is necessary to launch flier plate
s to hypervelocities. In addition, the high pressure loading must be u
niform, structured, and shockless, i.e., time-dependent to prevent the
flier plate from either fracturing or melting. In this paper, a novel
technique is described which allows the use of 100 GPa megabar loadin
g pressures and 10(9)-g acceleration to launch intact flier plates to
velocities of 12.2 km/s. The technique has been used to launch nominal
ly 1-mm thick aluminum, magnesium, and titanium alloy plates to veloci
ties over 10 km/s, and 0.5-nun thick aluminum and titanium alloy plate
s to velocities of 12.2 km/s.
