  • continued airworthiness of composite repairs to primary structures for Military Aircraft
    Composite Structures, 1995
    Co-Authors: Rhys Jones, W R Smith
    Abstract:

    The paper discusses policy and procedures for the use of damage tolerance methods for ensuring the continued airworthiness of (composite) structural repairs to Military Aircraft. In this work the focus is on repairs to principal structural elements (PSE) and structurally significant items (SSI). A modified form of the current FAA two stage evaluation and approval process is proposed. In this process the first stage is based on static structural strength considerations to keep the Aircraft down time to a minimum and the second stage requires a full damage tolerance evaluation to be performed. The proposed approval process also includes a requirement to prepare a suitable in-service inspection programme.

  • transonic free to roll analysis of abrupt wing stall on Military Aircraft
    Journal of Aircraft, 2004
    Co-Authors: D B Owens, Francis J Capone, Robert M Hall, Jay M Brandon, Joseph R Chambers
    Abstract:

    Transonic free-to-roll and static wind-tunnel tests for four Military Aircraft-the AV-8B, the F/A-18C, the preproduction F/A-18E, and the F-16C-have been analyzed. These tests were conducted in the NASA Langley 16-Foot Transonic Tunnel as a part of the NASA/Navy/Air Force Abrupt Wing Stall Program. The objectives were to evaluate the utility of the free-to-roll test technique as a tool for predicting areas of significant uncommanded lateral motions and for gaining insight into the wing-drop and wing-rock behavior of Military Aircraft at transonic conditions. The analysis indicated that the free-to-roll results agreed well with flight data on all four models. A wide range of motions-limit-cycle wing rock, occasional and frequent damped wing drop/rock and wing-rock divergence-were observed

  • free to roll analysis of abrupt wing stall on Military Aircraft at transonic speeds
    41st Aerospace Sciences Meeting and Exhibit, 2003
    Co-Authors: Bruce D Owens, Francis J Capone, Jay M Brandon, Kevin Cunningham, Joseph R Chambers
    Abstract:

    Transonic free-to-roll and static wind tunnel tests for four Military Aircraft - the AV-8B, the F/A-18C, the preproduction F/A-18E, and the F-16C - have been analyzed. These tests were conducted in the NASA Langley 16-Foot Transonic Tunnel as a part of the NASA/Navy/Air Force Abrupt Wing Stall Program. The objectives were to evaluate the utility of the free-to-roll test technique as a tool for predicting areas of significant uncommanded lateral motions and for gaining insight into the wing-drop and wing-rock behavior of Military Aircraft at transonic conditions. The analysis indicated that the free-to-roll results had good agreement with flight data on all four models. A wide range of motions - limit cycle wing rock, occasional and frequent damped wing drop/rock and wing rock divergence - were observed. The analysis shows the effects that the static and dynamic lateral stability can have on the wing drop/rock behavior. In addition, a free-to-roll figure of merit was developed to assist in the interpretation of results and assessment of the severity of the motions.

  • CNS/ATM for tactical Military Aircraft
    Digital Avionics Systems Conference 2003. DASC '03. The 22nd, 2003
    Co-Authors: S. Frain, G. Van Sickle
    Abstract:

    Military aircrews are beginning to experience the benefits of having quality global positioning system (GPS) navigation information available in the cockpit to support their tactical missions. However, another big improvement in situational awareness is the new capabilities known as communications, navigation, surveillance/ air traffic management (CNS/ATM). If tactical Military are to operate within this new performance based airspace, they require operational RNP RNAV, Mode S, and 1090ES ADS-B functionality. To achieve these functionalities, dual use avionics and integrations must be found to capture civil functionality with Military equipment. The bottom line is that tactical Military achieves the required functionality or they can expect delays, rerouting, and some airspace exclusions. This paper describes one way to get RNP RNAV, Mode S, and 1090ES ADS-B capability in tactical Military Aircraft.
