Patent number: 8764396Abstract: A lead-lag damper for a rotor assembly has a body mounted to either an inboard portion of a blade assembly or a fixed portion of the rotor assembly. A piston carried within the body is configured to allow for relative motion between the body and the piston. The piston defines opposing chambers within the body, the chambers being in fluid communication through a fluid passage. A link connects the piston to the other of the inboard portion of the blade assembly and the fixed portion of the rotor assembly, and the link engages a central portion of the piston. The piston acts on fluid in the chambers during relative motion between the piston and the body and causes fluid flow between the chambers through the fluid passage. Flow through the passage acts to damp lead-lag motion of the blade assembly relative to the fixed portion of the rotor assembly.Type: GrantFiled: February 12, 2008Date of Patent: July 1, 2014Assignee: Textron Innovations Inc.Inventors: Frank B. Stamps, James L. Braswell, David A. Haynie, Mithat Yuce

Patent number: 8602400Abstract: A vibration isolator is disclosed having a housing which defines a fluid chamber. A piston, which is movable to and from a down position, is disposed within the housing. A vibration isolation fluid is disposed within the fluid chamber. A passage having a predetermined diameter extends through the piston to permit the vibration isolation fluid to flow from one fluid chamber to the other. An elastic element is provided for reducing transmission of vibrations from the piston to the housing when the piston is at the down position.Type: GrantFiled: September 27, 2007Date of Patent: December 10, 2013Assignee: Textron Innovations Inc.Inventors: Emery N. Ward, Michael R. Smith, Frank B. Stamps, David Haynie, Terry K. Thompson, David P. Shipman, James A. Wilson

Patent number: 8480065Abstract: An elastomeric spring-damper has a one-piece tubular body having an integral cap. A tension stop flange is formed in the body near the cap portion, and a compression stop flange opposing the tension stop flange is formed on the cap portion. An inner member located within the body is coupled to the body with an annular elastomeric member, such that longitudinal motion of the inner member relative to the body is allowed through elastic deformation of the elastomeric member. An inner member stop flange is positioned between the compression stop flange and the tension stop flange to limit longitudinal motion of the inner member relative to the body.Type: GrantFiled: April 20, 2006Date of Patent: July 9, 2013Assignee: Textron Innovations Inc.Inventors: Lancer D. Halcom, Brian Bouquillon, David A. Haynie

Patent number: 7867096Abstract: A joint is configured for use with a rotary-wing aircraft having at least one engine. A driver is coupled to an output shaft of the engine, the driver being rotatable about an axis. A yoke is at least partially rotatable relative to the driver about a first center of rotation, the center of rotation being located on the axis. A plurality of upright links couple the yoke to the driver, each link being translatable relative to the yoke, the driver, or both. Each link is also rotatable relative to the yoke, the driver, or both, about a second center of rotation.Type: GrantFiled: June 7, 2005Date of Patent: January 11, 2011Assignee: Textron Innovations Inc.Inventors: Frank B.

Patent number: 7665969Abstract: An assembly for providing flexure to a blade of a rotary blade system, the assembly including an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween. At least one of the upper and lower yoke surfaces having a layer of cushioning material positioned thereon and secured thereto. The layer of cushioning material extending along and following the general contour of yoke surface, and the layer of cushioning material directly contacting a support plate. Another embodiment is an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween and directly contacting the support plates wherein one of the curved surfaces is a non-circular arc that does not form part of the circumference of a circle.Type: GrantFiled: January 24, 2005Date of Patent: February 23, 2010Assignee: Bell Helicopter Textron Inc.Inventors: Frank B.

Publication number: 20060229034Abstract: A handheld controller is for remotely controlling a mobile gaming unit, such as a remote-controlled car. The controller includes a housing having a longitudinal axis, a first controlling mechanism, such as a trigger, for controlling speed and direction of the mobile gaming unit and, a second controlling mechanism including a wheel member for controlling the steering of the mobile gaming unit. In order to provide an ergonomic gripping position, the wheel member is disposed at an angle between about 20 degrees and about 70 degrees, and preferably about 45 degrees, with respect to the longitudinal axis of the housing. The second control mechanism may be set-up in either of a right-handed or left-handed configuration, without requiring a separate intermediate extension member between the second controlling mechanism and the housing. An adjustable display which is pivotal with respect to the housing in order to provide a variable viewing orientation thereof, is also disclosed.Type: ApplicationFiled: March 29, 2005Publication date: October 12, 2006Inventors: Alexander Gizis, David Haynie, Chris Yatsko, Andrew Vellrath
