The authors experimentally study the dynamics of the accumulation of a bunch of shock compressed gas, formed when a plate is propelled at a substrate by a sliding detonation wave, propagating with a velocity of U/sub 0/ greater than 6 km/sec. The detonation velocity was chosen to exceed the velocity of sound in the plate and substrate materials, which ensured that particles and cumulative jets from the region of the point of contact would not be generated. A diagram of the experiments is shown. The study shows the existence of three states of gasdynamic flow (with stable accumulation of plasma, the stall state, and with no accumulation); the velocity of the direct shock wave formed exceeds the adiabatic velocity and increases as the gap size decreases; and, the strong solution is realized behind the front of the oblique shock wave -- the parameters of the bunch of shock-compressed gas formed are independent of the angle of flight of the propelled plate.
