  • Kliment, Linda K.; Rokhsaz, Kamran; Menon, Alok; Nelson, John; Terning, Brett; Weinstein, Edward M. (American Institute for Aeronautics and Astronautics, Inc., 2014-01-17)
    The USFS has collected flight data on Beechcraft King Airs which are being used as Aerial Supervision Modules. Data from seven aircraft is presented. The missions are separated into four flight phases: climb, cruise, ...
  • Rokhsaz, Kamran; Kliment, Linda K.; Weinstein, Edward M. (American Institute for Aeronautics and Astronautics, Inc., 2014-01-17)
    Operational flight loads have been analyzed from two business jets, a Global 5000 and a Global Express XRS. It is shown that due to the differing nature of their missions, both airframes were subjected to nearly the same ...
  • Denning, Shawn Patrick (Wichita State University, 2013-05)
    Over the past few decades both the demand for knowledge as well an increase in the application of composite materials has boomed. This has led to an intensive focus by the research community to gather information and ...
  • Chakravarthy, Animesh; Ghose, Debasish (Springer, 2012-02)
    Avoidance of collision between moving objects in a 3-D environment is fundamental to the problem of planning safe trajectories in dynamic environments. This problem appears in several diverse fields including robotics, air ...
  • Khurshid, Hassan (Wichita State University, 2012-07)
    A high-order finite difference solver was written to solve the incompressible Navier-Stokes (NS) equations and was applied to analyze the blood flow. First, a computer code was written to solve incompressible Navier- Stokes ...
  • Mahmoudnejad, Niloufar; Hoffmann, Klaus A. (Taylor & Francis, 2011)
    To address accuracy issues for direct numerical simulation, a hybrid scheme based on the weighted compact scheme (WCS) and weighted essentially non-oscillatory (WENO) scheme is developed. The new hybrid method incorporates ...
  • Suares, Ian Greg (Wichita State University, 2005-12)
    Large ice particles shed from an airframe can cause damage to downstream aerodynamic surfaces and aft mounted engines. A simulation tool was developed to compute the trajectories of shed ice particles and determine the ...
  • Nandakumar, Pratap Nuggehalli; Keshavanarayana, Suresh R. (Wichita State University. Graduate School, 2009-05-01)
    The energy dissipation due to the failure of composites is of particular interest for crash applications involving dynamic loading. Separation of layers or delamination which can occur in opening (mode-I) is one of the key ...
  • Tan, Kian Yip; Fazal Elyas, Sana (Wichita State University. Graduate School, 2010-04-23)
    This experimental study addresses the progressive crushing responses of laminated corrugated beams fabricated using Newport NB321/7781 E-glass prepreg material. Stacking sequences of [0]n and [45]n where n=4,8 and 12 have ...
  • Ghimire, Mohan (Wichita State University. Graduate School., 2007-04-27)
    A repair technique involving the containment of local bending of sandwich facesheet by strategically filling honeycomb core cells has been explored to improve the damage tolerance of impact damaged sandwich panels. The ...
  • Ghimire, Mohan (Wichita State University, 2008-05)
    The compressive residual strength and behavior of impact damaged sandwich panels are governed by the amount of non-visible core damage underneath the facesheets. The failure modes under in-plane compressive loading are ...
  • Arshed, Ghulam Murshed; Hoffmann, Klaus A. (Elsevier, 2013-03-29)
    Improvements in the numerical algorithm for the dynamics of flows that involve discontinuities and broadband fluctuations simultaneously are proposed. These two flow features suggest numerical strategies of a paradoxical ...
  • Bruner, Hugh S. (2007-05)
    The theory for an adaptive inverse flight controller, suitable for use on General Aviation aircraft, is developed in this research. The objectives of this controller are to separate the normally coupled modes of the basic ...
  • Nizampatnam, Lakshmi S. (Wichita State University, 2007-12)
    Typical bird shapes used in numerical bird strike analyses include a number of primitive geometries, such as the right circular cylinder, hemi-spherical cylinder, sphere and ellipsoid. There are also some simplifying ...
  • Pappu, Venkatasubramani S. R.; Steck, James E.; Rajagopal, Karthikeyan; Balakrishnan, S. N. (American Institute for Aeronautics and Astronautics, 2014-01)
    This paper presents some issues encountered while flight testing a Model Reference Adaptive dynamic inverse controller (MRAC), on a General Aviation (GA) fly-by-wire test bed. Adaptation was replaced with a Modified ...
  • Behrman, Elizabeth C.; Steck, James E. (Rinton Press, Inc., 2013-01)
    Measurement of entanglement remains an important problem for quantum information. We present the design and simulation of an experimental method for an entanglement indicator for a general multiqubit state. The system can ...
  • Aponso, Gayanath Tharaka Goniyamalimige (Wichita State University, 2013-12)
    This thesis investigates the feasibility of using Dynamic Inversion to develop control laws for time varying systems, specifically Miniature Morphing Air Vehicles. Two Linear Time Varying systems are investigated namely a ...
  • Kuenn, Aaron Douglas (Wichita State University, 2013-08)
    In this thesis, the lifting-line approximation of a flat, unswept wing, originally attributed to Prandtl, is investigated. The original formulation for a flat wing is examined in detail. The governing integro-differential ...
  • Malipeddi, Anil Kumar; Mahmoudnejad, Niloufar; Hoffmann, Klaus A. (American Institute of Aeronautics and Astronautics, 2012-09)
    The effects of biologically inspired leading-edge protuberances on aircraft wings were investigated by using a numerical scheme. Simulations were performed at a Reynolds number of 5.7 x 10(5) on wings with leading-edge ...
  • Malipeddi, Anil Kumar (Wichita State University, 2011-07)
    This thesis investigates the effects of biologically inspired leading-edge protuberances on aircraft wings. The study of humpback whales and their flipper performance was the impetus to modifying the leading edge of an ...
