Patent number: 9539772Abstract: The present application relates to a method and system that can be utilized to manufacturing composite structures in a closed cavity mold. The tool system includes a closed cavity tool with spring members that when in compression apply pressure to a preform located within the closed cavity mold. During a curing cycle, the spring members provide substantially constant pressure to the preform, thereby preventing voids and porosity in the cured composite structure. Further, the substantially constant pressure, provided by the spring members, acts to more effectively conform the preform to the geometry defined by a void in the closed cavity mold during the curing cycle.Type: GrantFiled: June 29, 2016Date of Patent: January 10, 2017Assignee: Textron Innovations Inc.Inventors: Stephen K. Bishop, Robert J. Greenberg, Forrest W. Henry

Patent number: 9213009Abstract: The present application relates to a method and system for optimizing a composite system by electrically monitoring the reactive and physiological behavior of the resin binder in a composite system, so as to develop the desired properties of the resin during the cure process. A method of manufacturing a composite part can include assembling a composite preform with a resinous material and an open circuit. Further, the method can include subjecting the composite preform to a curing cycle so that a resin in the resinous material melts and closes the open circuit. Further, the method can include electrically monitoring a current through the resin during the curing cycle. Further, the method can include selectively controlling a manufacturing variable in response to the step of electrically monitoring the current through the resin.Type: GrantFiled: December 15, 2011Date of Patent: December 15, 2015Assignee: Textron Innovations Inc.Inventors: Stephen K. Bishop, Jacob J. Hart

Patent number: 9162276Abstract: The system and method of the present application can include machining complex part features in a flat metal sheet, and subsequently forming the machined flat metal sheet to have the desired shape and contours. Prior to the step of machining the complex part features, the method can include calculating a scaled location of the complex part features so that the subsequent forming step acts to translate and deform the complex part features into a desired location.Type: GrantFiled: August 28, 2012Date of Patent: October 20, 2015Assignee: Bell Helicopter Textron Inc.Inventors: Stephen K. Bishop, Stephen S. Swenson, Crystal L. Wilson, Paulette D. Lemond

Publication number: 20120096714Abstract: A process for applying a plurality of coats of abrasion resistant material to a substrate such as a rotor for an air-craft. The abrasion resistant material is composed of a first and a second material. The coats gradually transition from an abrasion resistant composition having a larger percentage part per volume of the first material to a larger percentage part per volume of the second material as additional coats are applied.Type: ApplicationFiled: July 16, 2009Publication date: April 26, 2012Applicant: BELL HELICOPTER TEXTRON INC.Inventors: Stephen K.

Patent number: 5979798Abstract: Many industries such as construction and aerospace industries use high build coatings for various purposes. Spray system for applying high build coatings allow thick coating to be applied relatively quickly as opposed to manual methods. The present application provides for a spray system including a spray apparatus having a conveyance device which provides a motive force created by a vacuum for delivering a dry material to the nozzle of the apparatus, the conveyance device including an array of bores for separating the dry material to provide substantially uniform wetting of the dry material when the dry material enters the nozzle. The conveyance device is particularly useful in applying plaster and stucco. The present apparatus eliminates concerns of pot-life, waste and product uniformity by wetting the dry material close to the nozzle outlet.Type: GrantFiled: May 18, 1998Date of Patent: November 9, 1999Assignee: United Technologies CorporationInventors: Terry L.
