The invention discloses a variable-configuration multi-rotor water-air cross-medium aircraft which comprises a buoyancy shell, an air sealing cabin, a water sealing cabin and a deformable coaxial propeller device. The air-sealed cabin and the water-sealed cabin are arranged inside the buoyancy shell, and the deformable coaxial rotor device is arranged outside the buoyancy shell; wherein the air-tight cabin is located at the stern of the aircraft, and the water-tight cabin is located at the bow of the aircraft; a variable-volume buoyancy adjusting device is arranged in the air-tight cabin and used for controlling the buoyancy of the aircraft, and floating, diving and hovering movement of the aircraft are achieved. The resistance during sailing along the axis of the aircraft body is greatly reduced; the underwater navigation mode is switched through folding of the vehicle arms, the coaxial dual-power output is achieved, the neutral buoyancy state of underwater navigation is maintained through the variable-volume buoyancy adjusting device, the power output of the underwater power device is reduced, meanwhile, the propelling efficiency can be improved, and meanwhile posture adjustment is more flexible.

    本发明公开了一种变构型的多旋翼水空跨介质航行器,包括浮力外壳、气密封舱、水密封舱以及可变形共轴螺旋桨装置;所述气密封舱、水密封舱安置于浮力外壳内部,可变形共轴旋翼装置设置于浮力外壳外部;其中,气密封舱位于所述航行器艉部,水密封舱位于所述航行器艏部;所述气密封舱内设置变体积浮力调节装置,变体积浮力调节装置用于对航行器的浮力进行控制,实现航行器的上浮下潜以及悬停运动。本发明极大减小了沿机体轴线航行时阻力;通过机臂的收折切换水中航行模式,在具备共轴双动力输出外,通过变体积浮力调节装置维持水下航行的中性浮力状态,在减小水中动力装置功率输出的同时,可提高推进效率,同时使姿态调整更加灵活。
