Aircraft based on pneumatic pop-up cavitation device
According to the aircraft based on the pneumatic pop-up cavitation device, the pop-up cavitation device enables the underwater aircraft to have a shorter length during contraction, and the reduction of the length-diameter ratio facilitates the improvement of the space utilization rate during storage; meanwhile, the aircraft in a contracted state has a smaller turning radius during transfer, and the requirement of the aircraft on a space turning angle in the transfer process is reduced; the pneumatic ejection principle is adopted, and compared with a complex mechanical structure, pneumatic ejection is more direct and efficient; meanwhile, gas generated by fuel combustion of the aircraft is used for providing driving force, the situation that electronic components such as a servo mechanism are additionally arranged, and the complexity of an electronic system is increased is avoided, and after the aircraft reaches the stretching state, forward jet airflow is jetted out of the rear portion of the cavitator through a ventilation hole channel and an air jet hole, gas is supplemented for supercavitation navigation, and supercavitation navigation is supported; and compared with cavitation of a single cavitator, a supercavitation sailing state can be achieved at a lower sailing speed.
本发明的一种基于气动弹出式空化装置的航行器，弹出式空化装置可使得水下航行器在收缩时拥有更短的长度，减小长径比有利于提高贮存时的空间利用率；同时，在转运时收缩状态的航行器拥有更小的回转半径，减小其对转运过程中的空间转角的要求；本发明采用的是气动弹出原理，与复杂的机械结构相比，气动弹出更加直接高效；同时，利用航行器燃料燃烧产生的气体提供驱动力，避免了外加伺服机构等电子元器件增加电子系统复杂度，航行器达到伸展状态后，前射气流将经由通气孔道和喷气孔在空化器后部喷出，为超空泡航行补充气体，支持超空泡航行，与单一空化器空化相比，能够以更小的航速达到超空泡航行状态。
