The invention discloses an amphibious cross-medium aircraft and a cross-medium control method thereof. The whole aircraft is of a multi-rotor structure, wherein the number N of rotors is an even number greater than 4; a power system comprises n * N power units, each rotor is provided with n power units, and each power unit comprises a propeller and a motor used for driving the propeller, the total power P of each motor in the power system is not less than three times of hovering power of the whole machine, and the total thrust is not less than 1.5 times of dead weight of the whole machine; the horizontal size t of the cross-medium aircraft is far larger than or far smaller than the wavelength of waves to enter and exit the water area, and the overall density is larger than the density of water to enter the water area. According to the amphibious cross-medium aircraft, a multi-rotor structure is adopted, the compatibility to two working environments is effectively improved, the amphibious cross-medium aircraft can rapidly enter water, the serious influence of water surface fluctuation on stable water outlet is jointly solved through size design and power design of a power system, the water outlet speed can be shortened to be within 1 s, and the water outlet reliability can reach 99.8% or above.

    本发明公开了一种两栖式跨介质飞行器及其跨介质控制方法,整机采用多旋翼结构,旋翼的数量N为4以上的偶数,动力系统包括n*N个动力单元,各旋翼上均安装n个动力单元,动力单元包括螺旋桨和用于驱动螺旋桨的电机,动力系统中各电机的总功率P不小于三倍整机悬停功率,总推力不小于1.5倍整机自重;跨介质飞行器的水平尺寸t远大于或远小于待进出水域波浪的波长,整机密度大于待进入水域的水密度。本发明提供的两栖式跨介质飞行器,采用多旋翼结构,有效提高对两种工作环境的兼容性,能够快速入水,通过尺寸设计和动力系统功率设计,共同解决水面波动对稳定出水造成的严重影响,出水速度可缩短至1s内,出水可靠性可达99.8%以上。
