    • Gwinn, Norman (1984)
      A steady state transonic airfoil analysis code has been modified to include the presence of a vortex near the airfoil. The objective was to provide quasi-steady analysis of blade/vortex interaction for studying or predicting ...
    • Peraza Hernandez, Edwin (2012-04-20)
      Size dependent properties of Shape Memory Alloys (SMAs) in micro and nano scales have gained an increasing attention due to the existing and potential applications of SMAs in microelectromechanical systems (MEMS) and small ...
    • Mashio, Tomoka (1997)
      In the area of underwater vehicle design, the development of highly maneuverable vehicles is presently of interest with their design being based on the swimming techniques and anatomic structures of fish; primarily the ...
    • Ferguson, Samuel Wyatt III (1976)
      The purpose of this project has been to evaluate and compare methods for predicting rotor performance. This evaluation suggests that rotor performance prediction can be accomplished using simple closed form algebraic ...
    • Wagner, Elaine Ann (1980)
      As relatively large models are often used in wind tunnel testing, the effects of the confining walls must be determined for effective test data correction. Corrections and predictions for flow about a flat plate normal to ...
    • White, Gary P. (1976)
      A classical two-dimensional, bending-torsion flutter analysis of a reference airfoil in a cascade of infinite blades is performed. The unsteady airloads on the reference airfoil are predicted using a numerical lifting ...
    • Vassberg, John Charles (1980)
      A high altitude scientific balloon is a flexible structure where the shape and stress are dependent on the pressure differential across the envelope. When a balloon is floating at a constant altitude, the pressure distribution ...
    • Cogan, Thomas Joseph (1977)
      A recent development of the NASA Airfoil Research Program is a family of new high lift, low drag airfoils for application on general aviation aircraft. This study analyzes one of these airfoils, the 13% thick GA(W)-2, as ...
    • Bishop, Robert H. (1979)
      This paper describes the results of the initial phase of a program being conducted to develop systems and procedures to maximize ballast and lifting gas usage on board an atmospheric research balloon. Computer programs, ...
    • Ebersohn, Frans Hendrik (2010-07-14)
      Magnetic nozzles must convert thermal or gyro energy of the plasma to thrust while also inducing plasma detachment in order to be effective. Plasma detachment and methods to induce plasma detachment are examined. In ...
    • Budiman, Benny Susanto (1991)
      Single gimbal control moment gyroscopes are attractive actuators for spacecraft attitude control systems. However, intrinsic kinematic singularities preclude torque generation along certain directions and lead to loss of ...
    • Devolites, Jennifer (1993)
      A 4.05% model of the NASA Space Shuttle Orbiter was tested (Test 9238) at the Texas A&M University Low Speed Wind Tunnel (TAMU-LSWT) at various heights above the wind tunnel floor, in order to simulate the ground effect ...
    • Wilkins, Matthew (1997)
      A theoretical and experimental study of high current density transient thermoelectric cooling is undertaken in this paper. Both three region and five region thermodynamic heat transfer models are implemented in the theoretical ...
    • Wittig, Laurrie Ann (1991)
      This experiment should be sufficiently general in nature and to be applicable to a variety of specific experiments intended to study implementation issues associated with robust control theories/methodologies for systems ...
    • Proft, Eddy (1979)
      A review of the state of the art of wind design procedures for offshore structures indicated that wind/wave interactions were not taken into account. In hurricane conditions, large amplitude waves may cause cyclic loading ...
    • Keese, David L. (1977)
      In atmospheric balloon research it is very important to accurately describe the delicate balance of forces applied to a film and to use this analytical description to produce a suitable manufactured balloon shape. This ...
