The invention discloses a high-speed contra-rotating ducted fan, and relates to the technical field of aircrafts, in particular to a high-speed contra-rotating ducted fan which comprises a cylindrical casing, a fan inner shaft, a fan outer shaft, a first motor, a second motor, a first fan and a second fan, and the first motor and the second motor which are opposite in rotating direction are arranged in the cylindrical casing; the first motor rotor is connected with a fan inner shaft, and the fan inner shaft penetrates through the second motor rotor and the fan outer shaft to be connected with a first fan. The second motor and the first motor are coaxially arranged, the second motor is connected with a second fan through a fan outer shaft, and the fan outer shaft sleeves the transmission shaft and is coaxial with the fan inner shaft; the contra-rotating fan system has the advantages that the contra-rotating fan system is safe, reliable and high in transmission efficiency, the appearance of an originally-designed casing is not affected, the limited space in the casing is utilized to the maximum extent, the optimal contra-rotating fan system effect is achieved, the propulsion efficiency of an aircraft is improved, and carbon emission and energy loss are reduced.

    本发明公开了一种高速对转涵道风扇,涉及飞行器技术领域,具体涉及一种高速对转涵道风扇,包括筒状机匣、风扇内轴、风扇外轴、第一电机、第二电机、第一风扇和第二风扇,筒状机匣内设置有转动方向相反的第一电机和第二电机;第一电机转子连接有风扇内轴,风扇内轴穿过第二电机转子和风扇外轴连接有第一风扇;第二电机与第一电机同轴布置,第二电机通过风扇外轴连接有第二风扇,风扇外轴套设于传动轴外,且与风扇内轴同轴;其好处在于:此方案安全可靠,传动效率高,并且不影响原本设计的机匣外观,最大限度的利用机匣内有限的空间,达到最佳的对转风扇系统效果,提高飞行器的推进效率,减少碳排放和能量损耗。
