Flat offset type head load reduction and stability augmentation device for missile entering water at high speed

The invention discloses a missile high-speed water entry flat offset type head load reduction and stability augmentation device, and belongs to the field of missile water entry stability augmentation. The upward offset degree of the lower side of the missile head is weakened by adopting the flat offset appearance. The interior of the flat offset shell is mainly composed of a sealing layer, a foam layer, a buffer layer and an attaching layer in a stacked filling mode, the impact load is further reduced through the compressibility of materials, the internal structure is protected, and the load reduction effect is enhanced. The device is in a downward offset shape and is mounted at the head of the missile, the resultant force of fluid force borne by the missile after the missile completely enters water is downward and is opposite to the direction of the fluid force borne by the missile when the head of the missile just hits water, and then the trend that the head of the missile deflects upwards when the missile
