The invention discloses a separable bow structure of a supercavitation underwater vehicle. The separable bow structure comprises a split type flow guide cover unit, a power-losing type electromagnet unit, a connecting rib ring and an underwater vehicle hull. The split type flow guide cover unit is composed of a flow guide cover upper portion, a flow guide cover lower portion and buoyancy foam, andthe buoyancy foam is fixed to an inner surface of the flow guide cover upper portion in a bonding mode. The power-losing electromagnet unit is composed of a ferromagnetic disc and a power-losing electromagnet. The ferromagnetic disc is fixed on an internal rib ring of the split type flow guide cover unit; the four ferromagnetic discs are evenly distributed in a circumferential direction, an included angle between the center of each ferromagnetic disc and a boundary between the upper portion of the flow guide cover and the lower portion of the flow guide cover is kept to be 45 degrees, circular grooves are evenly formed in the connecting rib ring in the circumferential direction, and power-losing type electromagnets are installed in the circular grooves; a connecting rib ring is in threaded connection with the underwater vehicle hull; and a power line channel is further formed in the circular grooves and used for connecting the power-losing type electromagnets with a power supply unitin the underwater vehicle hull through a power line.
