Ricochet Characteristics of AUVs during Small-Angle Water Entry Process

Figure 9

Statistical graphs of whether ricocheting phenomena occur under different water entry conditions. , , and represent no ricochet, ricochet, and no water entry, respectively. (a) The statistics of angle of attack, velocity, and ricochet when the water entry angle is 20 degrees. (b) The statistics of angle of attack, angle of water entry, and ricochet when the water entry velocity is 100 m/s.
