Described duct comprises fixed mount, be enclosed within slurry protective case on the fixed mount, be sleeved on outer the falling the resistance cover, be installed in the swinging strut on the fixed mount of slurry protective case; Described vane sheet is mounted on the described swinging strut.
Be provided with the lifting support frame of belt wheel in bottom, described operator's saddle storehouse.
Described each layer blade construction comprises two vane sheets.
Described each layer blade construction comprises three vane sheets.
The present invention is owing to adopted said structure, by adopting and the different brand new combination of prior art, be staggeredly arranged by adopting each layer blade rotational structure to comprise that the vane sheet of the vane sheet of two to three vane sheets and above-mentioned upper strata blade rotational structure and lower leave rotational structure is, and the rotating speed of the vane sheet of described lower leave rotational structure is higher than the rotating speed of the vane sheet of described upper strata blade rotational structure, so two-layer rotating speed difference and lower floor's vane sheet wanted revving up to improve lift than upper layer vane sheet about the present invention divided by the vane sheet, thereby the present invention can greatly be lowered the rotative speed of each layer vane sheet and be reduced driving engine, the high load capacity action of drive mechanisms such as rotating speed case, it has greatly prolonged the service life of vane sheet; Be staggeredly arranged and the vane sheet divides two-layer rotating speed difference up and down by the vane sheet, and lower floor's vane sheet wants revving up to improve lift than upper layer vane sheet, so in the vane sheet work of two-layer blade rotational structure, air-flow can not interfere with each other, can be convenient to gas communication, increase raising force of the present invention.The present invention can realize handled easily by joystick, and its operation is very easy to.The present invention designs ingenious, compares with the conventional airplane high price, and the present invention is owing to having adopted less parts etc., so its cost is very low.
After the detailed description of reading embodiments of the present invention in conjunction with the accompanying drawings, it is clearer that characteristics of the present invention and advantage will become.
