Abstract: A jet-propelled water-entry composite buffer device for multi-channel gas recycling includes a head fairing, an underwater vehicle, a buffer, a cavitator and a side fairing. The side fairing is internally provided with a fairing body and a sealing choke plate, and a high-pressure gas cavity, a transition cavity and a sub-high-pressure gas cavity are formed by the fairing body and the sealing choke plate from front to back; a quota air pressure valve is disposed on the sealing choke plate; the fairing body is provided with pressure reducing holes; the high-pressure gas cavity, the transition cavity and the sub-high-pressure gas cavity form an gas cushion buffer. Gas acceleration holes communicated with the high-pressure gas cavity are further provided in the outer wall of the side fairing, so that a supercavity can be more favorably formed after the underwater vehicle enters water.
