The invention belongs to the technical field of high-speed water inlet of moving objects, in particular to a reverse air jetting air bubble assisting high-speed water inlet reducing impact load mechanism. The load mechanism comprises a high-pressure gas cylinder, a gas channel, a fairing, an engine, a spray pipe, a tail wing, air holes, a high-speed gas jet hole, a moving body, an air cavity, an electronic pressure regulating valve, an electronic flowmeter, a computer control device and a threaded connection device; the fairing is connected to the head of the moving body through threads, a plurality of air holes are uniformly distributed in the head of the moving body in the circumferential direction, the air holes are in communication with the annular air cavity in the shell, the engine is used for supplying air to the air cavity through the air channel, the air cavity is connected with the high-speed gas jet hole, the high-pressure gas cylinder is connected with the high-speed gas jet hole through an air channel arranged with the electronic pressure regulating valve and the electronic flowmeter, and the spray pipe is located at the tail part of the device. The high-energy gas jetis used for tearing a notch in front of the moving body to make contact with the water, the moving body does not need to be decelerated, most of the load resistance of the front surface is avoided, and the problem of contradiction between speed and water inlet resistance is solved.
