The invention discloses a self-sustaining type unmanned underwater vehicle with low power consumption and long endurance. According to the technical scheme, the underwater vehicle advances by means of underwater gliding, the effective attack angle is small and the resistance is low in the underwater gliding process, a low-energy-consumption propelling mode is adopted, and a large propelling distance can be achieved through a small height difference. And the underwater vehicle does not exchange mass with the outside, and the gravity of the underwater vehicle is basically unchanged, so that the possibility of water leakage of the underwater vehicle is reduced. And the expansion joint has elasticity, so that the compression energy of external fluid can be stored, and the energy consumption of the expansion joint is reduced. The underwater vehicle utilizes different positions and attack angles of the flapping wings to realize forward and backward maneuvering in the sinking and floating process, and has higher flexibility. The underwater vehicle consumes electric energy of the power supply only when the motor works and does not consume energy in most of the time in the gliding process, the electric energy of the power supply can come from fluid energy of environmental water flow, and the underwater vehicle achieves ultra-long endurance through the fluid energy of the water flow.
本申请公开了一种自持式低功耗长续航的无人潜航器。本技术方案中,潜航器利用水下滑翔前进,水下滑翔过程中有效攻角小、阻力低,是一种低能耗推进方式,较小的高度差即可实现较大的推进距离。潜航器与外界不存在质量的交换,自身重力基本不变,降低了潜航器漏水的可能性。并且膨胀节本身具有弹性,可以储存外界流体的压缩能,减小自身的能量消耗。潜航器利用扑翼不同的位置和攻角实现了沉浮过程中的前后机动,具有更大的灵活性。潜航器仅仅在电动机工作时消耗电源的电能,在滑翔过程中大部分时间不消耗能量,而电源的电能可来自于环境水流的流体能,潜航器通过利用水流的流体能实现超长续航。
