Patent number: 8651816Abstract: A fan blade connection system and method for connecting at least one composite blade (110) to a rotor hub (120), more particularly, for fans used in industrial ventilation and cooling applications. The invention aims to provide a better connection, mainly in regard to the stresses distribution. The preferred embodiments are directed to a system and method for connecting a composite blade (110) to a rotor hub (120) comprising a fastener element (130) arranged in the blade root (111) and extending transversally to the longitudinal axis of the blade (110), said fastener element (130) being adapted for receiving one of the ends of a tensioning member (140) in a longitudinal position in relation to said blade (110). The tensioning member (140) may have an intermediary interface (160) between the blade (110) and the rotor hub (120), fixed by the end of the tensioning member, or fixed by at least one fastener component, which passes through holes in the rotor hub and in the intermediary interface.Type: GrantFiled: March 6, 2007Date of Patent: February 18, 2014Assignee: Fantech Tecnologia em Sistemas de Ventilacao LtdaInventor: Bento Massahiko Koike

Patent number: 8647063Abstract: Provided is a multi-element rotor blade, including a primary element and at least one complimentary element, each having an aerodynamic profile. The primary element is joined by fastening elements to the at least one complimentary element such that the at least one complimentary element is adjacent to the primary element in a chordwise direction perpendicular to an axis of rotation of the blade and perpendicular to a longitudinal length of the blade. The at least one complimentary element is disposed closer to a blade root end of the primary element than to an opposite end of the primary element.Type: GrantFiled: March 13, 2007Date of Patent: February 11, 2014Assignee: Tecsis Tecnologia Sistemas Avançados S.A.Inventor: Bento Massahiko Koike

Patent number: 8313272Abstract: The present invention consists of a packing device for logistics of groups of wind turbine rotor blades, preferably of pairs of blades, including at least two structures, each one having a peripheral frame. For guaranteeing the proper conditions for the logistics, said blades are supported and fastened to the structures by flexible belts stressed by ratchets, being said blade profile partially or entirely enveloped by said flexible belts. And alternatively, the device for logistics of groups of wind turbine rotor blades may include tip protection cover, blades fastening device, such as belts, ropes or chains, and protecting devices on areas of contact between the blades to prevent the friction.Type: GrantFiled: December 9, 2005Date of Patent: November 20, 2012Assignee: TECSIS Technologia E Sistemas Avançados LtdaInventor: Bento Massahiko Koike
