Abstract

The present invention provides a vehicle based on a pneumatic pop-up cavitation device. The pop-up cavitation device can make the underwater vehicle have a shorter length when it is retracted, and reducing the aspect ratio is beneficial to improving the space utilization rate during storage; at the same time, the vehicle in the retracted state during transportation has a smaller turning radius, reducing its requirement for the spatial turning angle during transportation; the present invention adopts the pneumatic pop-up principle, and compared with complex mechanical structures, pneumatic pop-up is more direct and efficient; at the same time, the gas generated by the combustion of the vehicle fuel is used to provide driving force, avoiding the increase in the complexity of the electronic system by adding electronic components such as external servo mechanisms. After the vehicle reaches the extended state, the forward airflow will be ejected at the rear of the cavitator through the ventilation channel and the jet hole to supplement gas for supercavitation navigation and support supercavitation navigation. Compared with the cavitation of a single cavitator, the supercavitation navigation state can be achieved at a lower speed.
