The invention discloses a belt updraught type airplane which comprises a rotating shaft (1), a rotating piece (2) and a pressing head (3), the rotating piece (2) comprises a blade (2-1) and an edge (2-2), and the edge (2-2) is connected with the blade (2-1) in a welded mode below the back face of the blade (2-1); when the blades (2-1) rotate at a high speed, negative pressure is generated on the back surfaces of the blades, and meanwhile, negative pressure is also generated on the upper surfaces of the edges; the direction of the pulling force generated by the negative pressure is upward and is opposite to the direction of the gravity of the airplane, at the moment, a part of the gravity of the airplane can be resisted by a lifting force, and under the condition that the power of the airplane is not changed, the speed of the airplane is increased, and the working efficiency is improved; certainly, a certain amount of load can be increased, and the speed is the same as the original speed; the navigational speed of the aircraft is increased under the condition that the cost of the aircraft is not increased much; the load can be increased under the condition that the speed is the same as that of the prior art; certainly, the working efficiency is improved.
本发明公开了一种包括转轴(1)、转片(2)和压头(3)的带上吸式飞机,转片(2)包括叶片(2‑1)和沿边(2‑2),沿边(2‑2)在叶片(2‑1)背面的下方与叶片(2‑1)焊接相联;当叶片(2‑1)当叶片高速转动时,叶片背面会产生负压,同时,加上沿边的上面也会产生负压;而这样负压产生的拉力方向是向上的,是与飞机重力方向相反的,这时,飞机的重力会有一个提升力抵去一部分,飞机动力不变的情况下,飞机的速度会增加,工作效率增加;当然,也可以增加一定量的载荷,而速度跟原来相同;飞机在增加成本不多的情况下,航速得到提升;也可以速度与现有一样情况下,载荷可以增加;当然,工作效率增加。
