Method for stably entering navigation body into water at small angle

According to the method, a bubble cavity is formed through near-sea-surface underwater explosion, after explosion bubbles expand to 60% or above of the maximum radius, the navigation body and the liquid level are in a small-angle state, the bubbles are pricked into the navigation body, the pricked position is located above the water surface of the bubbles, and the navigation body begins to enter water after penetrating through the bubbles. According to the invention, the slamming load when the navigation body enters the water can be greatly reduced, and the unstable phenomena such as bouncing and sudden flapping when the navigation body enters the water at a small angle are weakened. Inducing bubbles generated by explosion can further reduce bubble wrapping when the navigation body enters water, so that the tail beat phenomenon is weakened, and the stability of the navigation body entering the water trajectory is further improved. The stability of the underwater attitude of the navigation body can be effectiv
