Considering the interaction between the flow around underwater vehicles and the supersonic gas jets, supersonic gas jets submerged in ambient liquid environment from a vertically moving vehicle were experimentally studied. In the experiments, a high-speed camera system was used to observe the evolution of the gas jet bubbles, and a dynamic pressure measurement system was used to measure the pressure fluctuation at underwater vehicle bottom. The results showed that the main shape of the cavity formed by the supersonic gas jets in still water gradually changed into quasi-ellipsoid ones. Due to the influence of Rayleigh-Taylor instability, the bulge phenomenon occurred in some domains close to the nozzle outlet. The jet penetration distance decreased with the increase of nozzle expansion ratios. For the tail jets characteristics of an underwater vertically moving vehicle, asymmetric cavity walls may be formed at the start-up stage of ventilation. The interaction between the flow around underwater vehicles and supersonic gas jets led to the cavity oscillations, which gradually disappeared in the working stage. The supersonic gas jets continuously disturbed the near-field flow, and the vehicle bottom pressure successively presented the characteristics of transient impact pressure peak, wide fluctuation in the initial stage, high frequency fluctuation in the working stage, and stable atmospheric pressure after water exit. The shear flow generated by the high-speed motion of the vehicle can suppress the high frequency oscillation of the tail jets, and the pressure oscillation in the 200—
