<P>PROBLEM TO BE SOLVED: To provide a technique of controlling an angle of attack, capable of stably controlling an angle of attack of a blade of a translational blade. <P>SOLUTION: A fluid flow control apparatus in which translational blade vanes 1 go around an elliptic track in parallel is referred to as a translational blade. In the translational blade, connection part-equipped power transmission wheels 4 are connected to both blade ends of the translational blade vane 1 to establish the elliptic track. A flow of a fluid is controlled by wheeling the connection part-equipped power transmission wheels 4 in an interlocked manner while periodically controlling angles of attack of the translational blade vanes 1. The translational blade vane 1 comprises a blade part 2 and blade end connection parts 3 connected to both blade ends thereof. The blade end connection part 3 is provided with angle-of-attack support portions 3c for stabilizing the angle of attack at three or more positions not on the same straight line. <P>COPYRIGHT: (C)2013,JPO&INPIT |
