Cross-flow fan, lift generator with it and aircraft with it

摘要

PROBLEM TO BE SOLVED: To provide a cross flow fan capable of increasing wind pressure and air volume without increasing the diameter. SOLUTION: A cross flow fan 3 has a plurality of vanes 15 arranged around a rotation axis C1 at predetermined intervals in the circumferential direction, tongue portions 17 arranged on the outer peripheral side of the vanes 15, and vanes 15. A cylinder 23, which is provided on the inner peripheral side and on the tongue 17 side of the rotation axis C1 and rotates around the central axis C2 parallel to the rotation axis C1, and the cylinder 23 are made into a flow flowing on the rotation axis C1 side. It is equipped with a cylindrical drive motor that rotates in the direction along the line. [Selection diagram] Fig. 2
