The invention provides a cylinder shaft coaxial propeller reversing ducted aircraft. A cylinder shaft and a duct outer cylinder are each of a cylindrical structure, the duct outer cylinder is arrangedon the peripheral side of the cylinder shaft in a sleeving mode, an annular cavity is formed between the inner side wall of the duct outer cylinder and the outer side wall of the cylinder shaft, anda first gear ring is rotatably connected to the outer side wall of the cylinder shaft through a first bearing; a second gear ring is rotatably connected to the outer side wall of the cylinder shaft through a second bearing, a commutator is connected to an output shaft of a driving motor, a first gear and a second gear are fixed to two output shafts of the commutator separately, the first gear is in meshing transmission with the first gear ring, and the second gear is in meshing transmission with the second gear ring; and the rotating direction of the first gear ring is opposite to that of thesecond gear ring, a plurality of upper propellers are fixed to the outer ring of the first bearing, and a plurality of lower propellers are fixed to the outer ring of the second bearing. The aircrafthas the effects that the problems of high price, safety, take-off and landing field, balance, storage and carrying, which cause a conventional aircraft not to be popularized, are solved by combining the cylinder shaft with a duct and coaxial propeller reversing.

    本发明公开一种筒轴共轴反桨涵道飞行器,筒轴和涵道外筒均为圆筒状结构,涵道外筒套设在筒轴外周侧,涵道外筒内侧壁与筒轴外侧壁之间形成有环形空腔,第一齿圈通过第一轴承转动连接在筒轴外侧壁,第二齿圈通过第二轴承转动连接在筒轴外侧壁,驱动电机输出轴连接有换向器,换向器两个输出轴分别固定有第一齿轮和第二齿轮,第一齿轮与第一齿圈啮合传动,第二齿轮与第二齿圈啮合传动,第一齿圈的转动方向与第二齿圈的转动方向相反,第一轴承的外圈固定有多个上螺旋桨,第二轴承的外圈固定有多个下螺旋桨。效果:通过采用筒轴结合涵道和同轴反桨,解决以往飞行器不能普及的问题:价格贵、安全问题、起降场地问题、平衡问题、存放和搬运问题。
