    • Wake behavior downstream of a transonic compressor rotor 

      Stephens, Harry Elias (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1974, 1974)
      Measurements of the static pressure resolved in radial and axial directions downstream of a transonic compressor rotor have been harmonically analyzed. The investigation is part of a program addressing the behavior of ...

    • Wake induced blade forces in turbo-machines 

      Lefcort, Malcolm D. (Malcolm David) (Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1962], 1962)
      The wake interaction problem in a turbo-machine has been simulated in a water table. The pressure distribution over a compressor blade during the passage of a wake shed by an upstream wake generator has been determined ...

    • Wall-shear-stress and laminarisation in accelerated turbulent compressible boundary-layers 

      Nash-Weber, James Ludlow (Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine Laboratory, [1968], 1968)
      Turbulent-laminar transition in compressible, steeply-accelerated, adiabatic, turbulent boundary layers on a smooth wall was investigated experimentally in the ranges of Mach and Reynold's numbers typical of nozzles used ...

    • Wave drag in transonic axial compressors 

      Okurounmu, Olufemi (Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine Laboratory, [1967], 1967)
      Profiles of fluid properties, including flow angle, static and total pressures have been obtained behind a free wheeling 8" diameter transonic rotor. The latter consists of 40 blades with double circular arc profiles, a ...

    • Wavefront control in space with MEMS deformable mirrors for exoplanet direct imaging 

      Cahoy, K. L.; Marinan, A. D.; Novak, B.; Kerr, C.; Nguyen, T.; e.a. (SPIE-SOC Photo-Optical Instrumentation Engineers, 2013-10)
      To meet the high contrast requirement of 1 x 10(-10) to image an Earth-like planet around a sun-like star, space telescopes equipped with coronagraphs require wavefront control systems. Deformable mirrors (DMs) are a key ...

    • Weather conditions affecting VTOL airbus operations in the Northeast Corridor 

      Simpson, R. W. ([Cambridge, Mass.] : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1966], 1966)
      A detailed study of hourly weather observations in the Northeast Corridor during the periods 0600-2400 for a ten year period 1944-1958 was made to study the implications of weather affecting the operations of a VSTOL Airbus ...

    • Wide-body aircraft demand potential at metropolitan Washington airports 

      Ausrotas, Raymond A.; Taylor, Morais Anthony. (Cambridge, Mass. : Flight Transportation Laboratory, Massachusetts Institute of Technology, [1976], 1976)
      Introduction: At present there is concern regarding the feasibility and future impact of allowing service by wide-body aircraft into National Airport in Washington. Some of the important issues are: (i) To what extent would ...
