  • Chadegani, Alireza; Yang, Chihdar; Smeltzer, Stanley S., III (AMER INST AERONAUT ASTRONAUT, 2012-03)
    This paper presents an analytical model to determine the strain energy release rate due to an interlaminar crack of the surface ply in adhesively bonded composite joints subjected to axial tension. Single-lap shear-joint ...
  • Chakravarthy, Animesh; Ghose, Debasish (IEEE, 2011-12)
    The problem of collision prediction in dynamic environments appears in several diverse fields, which include robotics, air vehicles, underwater vehicles, and computer animation. In this paper, collision prediction of objects ...
  • Dorfling, Johann; Rokhsaz, Kamran (American Institute for Aeronautics and Astronautics, Inc., 2014-01-17)
    Propeller optimization by means of calculus of variations is addressed in this paper. A procedure for deriving the Euler-Lagrange equations for both unconstrained and constrained propeller blade twist optimization is ...
  • Kral, Zachary Tyler; Horn, Walter J.; Steck, James E. (Hindawi Publishing Corporation, 2013)
    Aerospace systems are expected to remain in service well beyond their designed life. Consequently, maintenance is an important issue. A novel method of implementing artificial neural networks and acoustic emission sensors ...
  • Syed, Shoeb Ahmed; Hoffmann, Klaus A. (AMER INST AERONAUTICS ASTRONAUTICS, 2013-05)
    Aerodynamic noise generation due to the presence of surface discontinuity has been a topic of research for more than five decades. Most investigations carried out are on cavities ranging from small gaps to large cavities ...
  • Paranjape, Aditya A.; Chung, Soon-Jo; Hilton, Harry H.; Chakravarthy, Animesh (The American Institute of Aeronautics and Astronautics, 2012-05-05)
    The purpose of this paper is to analyze and discuss the performance and stability of a tailless micro aerial vehicle with flexible articulated wings. The dihedral angles can be varied symmetrically on both wings to control ...
  • Vizzini, Anthony (SAMPE Publishers, 2014-07)
    A message from SAMPE'S global president: The last time I wrote this note, I was ending my tenure as the International President of SAMPE. I am now writing as the Global President of SAMPE. So much has occurred in the world ...
  • Vizzini, Anthony (SAMPE Publishers, 2014-09)
    SAMPE was born among nine individuals working in the aerospace industry in Southern California, a likely place in 1944 for rising concerns on the lack of focus on materials and processing within their industry. It was ...
  • Vizzini, Anthony (SAMPE Publishers, 2014-11)
    I have been a member of SAMPE for 27 years. During that time, my professional network and my participation in the society has grown. I began by going to local chapter meetings, then I went to conferences in the United ...
  • Smith, Bert; Shivally, Praveen; Kumar, Brijesh (AMER INST AERONAUT ASTRONAUT, 2012-03)
    The purpose of this study was to determine the effect of dents on the stable crack growth in 0.04-in.-thick 2024-T3 bare aluminum sheet. The test specimens were either pristine, dented, or reworked. The edge-cracked ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Mahmoudnejad, Niloufar; Hoffmann, Klaus A. (AMER INST AERONAUT ASTRONAUT, 2012)
    In this investigation, wall-pressure fluctuations due to a turbulent boundary layer are estimated by various numerical methods. Four different turbulence models, including one- and two-equation models and a recently developed ...
  • Shaik, Eleyas; Hoffmann, Klaus A.; Dietiker, JF. (Tech Science Press, 2007-03)
    A potential interaction between the local hemodynamics and the artery wall response has been suggested for vascular graft failure by intimal hyperplasia (IH). Among the various hemodynamic factors, wall shear stress has ...
