Document Type and Number:
WIPO Patent Application WO/2005/058696
Kind Code:
A1
Abstract:
The invention provides an aircraft capable of taking-off vertically, in particular a device of taking-off vertically without rotors. Besides an engine, a gearbox, a fan, the device also includes two boards set in the left and right sides for wind blocking, which form a kind of structure like a half wind tunnel. The fan is contained therein. The multiple flaps group is set along the direction of flow. Each flap is rotatablely mounted on the wind-blocking boards and is arranged from higher to lower along the direction of airflow. The flaps group is equipped with the attack angle adjustment mechanism. The special feature of the arrangement of flaps could attain CL/CD≉20±5 and higher. Accordingly the device according to the invention is a novel combination of the lift and the drag, and is able to perform landing and taking-off vertically under zero cruising speed and attains the cruising distance R≥1600km.
