The underwater bubbly curtain vertical launching experimental device is used for underwater launching experiments.

Description

technical field [0001] The invention relates to an underwater air curtain vertical launch experiment device, which belongs to the technical field of research on underwater launch of a vehicle. Background technique [0002] Classified according to the state of the multiphase flow field in the barrel of the vehicle and near the mouth of the barrel, the conventional vertical launch methods of the underwater vehicle can include wet launch and sealed launch. The air curtain launch method is a new type of vertical launch method for underwater vehicles. The underwater air curtain launch refers to the launch method in which a gas channel is formed above the mouth of the launch tube by using a gas jet, and the vehicle moves in the gas channel. The launching device is composed of two concentric cylinders, and the outer cylinder of the concentric cylinders emits a gas jet to form a gas channel in the direction of the flying body exiting the cylinder. [0003] The underwater vertical l...
