  • Passive venting technique for shallow cavities
    Patent number: 5018688
    Abstract: A device for reducing drag and store separation difficulties caused by shallow cavities on aircraft in supersonic flight consisting of a slab of porous material cut to fit precisely inside the cavity. This slab is mounted inside the cavity such that a plenum chamber is formed between the slab and the floor of the cavity. This device allows air to flow through the chamber opposite to the direction of flow outside the chamber. This results in reduced drag and improved store separation characteristics.
    Type: Grant
    Filed: September 28, 1988
    Date of Patent: May 28, 1991
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics
    Inventors: Robert L. Stallings, Jr., Floyd J. Wilcox, Jr.
  • Passive venting technique for shallow cavities
    Patent number: 4863118
    Abstract: A device for reducing drag and store separation difficulties caused by shallow cavities on aircraft in supersonic flight consisting of a group of hollow pipes the same length as the cavity. The pipes are attached to the cavity floor so as to allow air to flow through the pipes. This device allows air to flow through the pipes opposite to the direction of flow outside the pipes. This results in reduced drag and improved store separation characteristics.
