Patent number: 8060232Abstract: Methods and computer storage media provide for the installation of potted inserts and installation validation. According to embodiments described herein, an insert is placed within an insert aperture of a panel or other structure. Potting compound is injected into a potting cavity surrounding the insert through a fill hole in the insert until potting compound overflows from another fill hole. The installation is validated by applying a force to the installed insert at a determined frequency using a mechanical impedance instrument and measuring a response frequency. The response frequency is compared to an acceptable frequency range to determine whether the insert is properly installed.Type: GrantFiled: June 13, 2008Date of Patent: November 15, 2011Assignee: The Boeing CompanyInventors: Michael P. Kuntz, Mark L. Younie, Gary E. Georgeson

Patent number: 6996913Abstract: An apparatus and method are provided for circumferentially measuring cross-sectional characteristics of a tubular member. The apparatus includes first and second template members that cooperably define an aperture for receiving the tubular member. At least one of the template members is adjustable so that the aperture can be adjusted between open and closed positions. A measurement device can be configured to detect the relative position of the first and second template members, thereby measuring the relative adjustment of the members between the open and closed positions. This measurement is indicative of the cross-sectional size of the tubular member, e.g., for determining the diameter of the tubular member. Alternatively, multiple measurement devices can respond to a contact force between the measurement devices and the tubular member, e.g., to determine a variation in wall thickness of the tubular member.Type: GrantFiled: January 29, 2004Date of Patent: February 14, 2006Assignee: The Boeing CompanyInventors: Matthew K.

Patent number: 6217000Abstract: A method and tooling concept for fabricating complex composite parts is provided. The method and tooling concept use various tooling configurations in order to produce varying magnitudes of thermal expansion at different areas within the tooling concept. The varying magnitudes of thermal expansion allow the tool concept to account for varying magnitudes of tool movement needed to debulk and consolidate varying thickness areas of the composite workpiece being cured. The tooling concept is formed of different materials having different thicknesses that allow the tooling concept to produce varying magnitudes of thermal expansion. The exterior surface of the tooling concept is covered by a compliant covering. The compliant covering helps to equalize the consolidation pressures produced by the tooling concept during curing. A composite wing box structure fabricated using the method and tooling concept is also disclosed.Type: GrantFiled: September 30, 1998Date of Patent: April 17, 2001Assignee: The Boeing CompanyInventors: Mark L.

Patent number: 5833786Abstract: A method for fabricating composite parts having improved pulloff strengths between portions of the composite part. In one embodiment, a sine wave spar is formed from two U-shaped channels having opposing flanges and a central web. The U-shaped channels are joined along the webs. The triangular gaps between the edges of the joined U-shaped channels are filled using a titanium radius filler that is configured to fit within the gaps. After the titanium radius filler is placed within the gaps, additional layers of composite material are placed over the titanium radius filler and the flanges of the U-shaped channels to form the caps of the I-beam. The resulting composite workpiece is then placed within appropriate tooling and cured within an autoclave. In other embodiments, the method of the invention is used to form spars, ribs, stringers, or bulkheads from composite materials.Type: GrantFiled: May 16, 1996Date of Patent: November 10, 1998Assignee: The Boeing CompanyInventors: Douglas A. McCarville, John S. Howitt, Jr., Mark L. Younie
