Patent number: 10272987Abstract: A slat cove filler is utilized to reduce airframe noise resulting from deployment of a leading edge slat of an aircraft wing. The slat cove filler is preferably made of a super elastic shape memory alloy, and the slat cove filler shifts between stowed and deployed shapes as the slat is deployed. The slat cove filler may be configured such that a separate powered actuator is not required to change the shape of the slat cove filler from its deployed shape to its stowed shape and vice-versa. The outer contour of the slat cove filler preferably follows a profile designed to maintain accelerating flow in the gap between the slat cove filler and wing leading edge to provide for noise reduction.Type: GrantFiled: January 25, 2016Date of Patent: April 30, 2019Assignee: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE ADMINISTRATOR OF NASAInventors: Travis L. Turner, Reggie T. Kidd, David P Lockard, Mehdi R. Khorrami, Craig L. Streett, Douglas Leo Weber

Publication number: 20150056453Abstract: A composite article, including a metal alloy haying a first surface and a shape memory polymer (“SMP”) adjoining the first surface, with a coupling agent condensed on the first surface between the metal alloy and the SMP. The coupling agent includes at least one metal alloy bonding group which chemically bonds to the metal alloy member and at least one SMP bounding group which chemically bonds to the SMP member. A method for forming the article includes resurfacing a first surface of the metal alloy and applying a coupling agent to the first surface, and then positioning the SMP thereon. The article is then treated to condense the coupling agent on the first surface. A toughening agent is optionally added to the SMP prior to coupling the SW and the metal alloy.Type: ApplicationFiled: August 19, 2014Publication date: February 26, 2015Inventors: Jin Ho Kang, Emilie J.

Patent number: 8763958Abstract: A multi-element airfoil system includes an airfoil element having a leading edge region and a skin element coupled to the airfoil element. A slat deployment system is coupled to the slat and the skin element, and is capable of deploying and retracting the slat and the skin element. The skin element substantially fills the lateral gap formed between the slat and the airfoil element when the slat is deployed. The system further includes an uncoupling device and a sensor to remove the skin element from the gap based on a critical angle-of-attack of the airfoil element. The system can alternatively comprise a trailing edge flap, where a skin element substantially fills the lateral gap between the flap and the trailing edge region of the airfoil element. In each case, the skin element fills a gap between the airfoil element and the deployed flap or slat to reduce airframe noise.Type: GrantFiled: April 18, 2012Date of Patent: July 1, 2014Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Travis L.
