Patent Searching and Data


Title:
TRANSLATIONAL VANE MACHINE
Document Type and Number:
Japanese Patent JP2006249999
Kind Code:
A
Abstract:

To provide a method for rotating and returning without using external power even if a pitch angle of a blade of a translational vane windmill becomes 0 degree once, a method for increasing quantity of air flowing into a rotor without changing a windmill rotor part of an existing windmill, and a method for making gyroscopic moment of the windmill substantially zero.

The method for rotating and returning from the pitch angle of 0 degree by utilizing restoring force of an elastic body such as a spring is provided. The method for increasing quantity of air flowing into the rotor by reducing pressure on a rear flow side of the rotor and increasing pressure gradient in the front and the rear of the rotor is provided. The method for canceling gyroscopic moment and making gyroscopic moment on the whole zero by installing a pair of windmills side by side and reversing the direction of rotation of rotors for each other is provided. A method for changing wind receiving area by an expansible blade is adopted.
