The invention relates to the technical field of aircrafts, in particular to an aircraft with double-layer rotors rotating in the same direction and at the same speed. The device comprises a rack, wherein a power device is arranged in the rack, and a flight device is arranged at the top of the rack and comprises a first flight unit and a second flight unit; the first flight unit comprises a sleeve,a second rotating bearing and lower-layer rotor wings symmetrically fixed to the two sides of the second rotating bearing, the second rotating bearing is fixed to the sleeve, the sleeve is fixed to the rack, the second flight unit comprises a transmission rod, a first rotating bearing and upper-layer rotor wings symmetrically fixed to the two sides of the first rotating bearing, and the first rotating bearing is fixed to one end of the transmission rod; the other end of the transmission rod penetrates through the sleeve and is connected with a power device in the rack, the transmission rod isconnected with the sleeve through a linear bearing, and the power device drives the transmission rod to vertically reciprocate up and down in the sleeve, so relative opening and closing movement is generated between the upper-layer rotor wing and the lower-layer rotor wing; and a linear bearing I and a linear bearing II are respectively arranged on the lower-layer rotor wing on two sides of the rotating bearing II.
本发明涉及飞行器技术领域,特指一种双层旋翼同向同速转动的飞行器,包括机架,机架内设有动力装置,机架顶部设有飞行装置,飞行装置包括第一飞行单元与第二飞行单元,第一飞行单元包括套筒、转动轴承二以及对称固定于转动轴承二两侧的下层旋翼,转动轴承二固定于套筒,套筒固定于机架,第二飞行单元包括传动杆、转动轴承一以及对称固定于转动轴承一两侧的上层旋翼,转动轴承一固定于传动杆一端,传动杆另一端穿过套筒,并与机架内的动力装置连接,传动杆与套筒之间通过直线轴承连接,动力装置驱动传动杆在套筒内垂直上下往复动作,使上层旋翼与下层旋翼之间产生相对的张合运动,转动轴承二两侧的下层旋翼上分别设有直线轴承一与直线轴承二。
