The safety of a rocket-assisted torpedo entering water becomes more sensitive to the water-entry angle as the water-entry speed of the torpedo increases. Conical pendulum motion is likely to occur during the descent of the torpedo-parachute system. The pendulum movement causes the torpedo to have an excessively large angle of attack when it enters the water. resulting in a large impac... https://www.nacrack.com/hot-savings-HiBoost-Home-15K-Smart-Link-F20G-5S-IoT-limited-super/
