3. RESULTS

All the experimental conditions and results of 145 shots are summarized in Table 1 . Although the impact velocity range of the experiments is 80 to 200 m/s which are lower than the predicted impact velocity of the LUNAR-A penetrator, the deceleration (and deceleration load) in the present experiments are approximately in the same range as that encountered in the real LUNAR-A penetrator. In the following, we focus our discussion on the effects of the nose shape of the penetrator and the attack angle on penetration characteristics. We believe that those experimental data can be used to assess the penetration dynamics of the LUNAR-A penetrator, if a proper care is taken for a scaling law.
