THE CHARACTERISTICS OF DAMAGE CAUSED BY HIGH-VELOCITY IMPACT ON THE WHIPPLE SHIELD OF LAVA SIMULATING METEOROID

 Numerical hypervelocity impact experiments were carried out for spacecraft typical Whipple shield with lava simulated
meteoroids. It is shown that during the hypervelocity impact, the damage on the back plate is manifested by the concentration of energy, and it  becomes more and more severe with the increase of impact velocity. The debris of the front plate also is an important damage element of the back plate, and the pits made by the debris are deep and big.
