The value of revenue management innovation in a competitive airline industry
(Cambridge, MA : [Massachusetts Institute of Technology], Flight Transportation Laboratory, [1995], 1995)The value of revenue management to the airlines has been amply demonstrated, both by industry experience and in simulation studies of the reservation process. However, there have been no attempts to determine if the benefits ... -
Vehicle routing and scheduling for the ultra short haul transportation system
(Cambridge, Mass. : Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, Flight Transportation Laboratory, 1979, 1979)A method of vehicle routing and scheduling for an air based intraurban transportation system is developed. The maximization of level of service to passengers in a system operating under time varying demand is considered ... -
Visualization of Three Dimensional CFD Results
(Computational Fluid Dynamics Laboratory, 1989-05-01)We have developed an interactive graphics system for the display of three dimensional CFD solutions on unstructured hexahedral grids. This system is implemented on a high-performance graphics supercomputer. Visualization ... -
Vortex decay in a conical diffuser
(Cambridge, Mass. : b Gas Turbine Laboratory, Massachusetts Institute of Technology, [1964], 1964)The behavior of vortex flow in a conical diffuser has been studied in this report. The flow considered here is a steady, incompressible, axially symmetric one. The present experimental investigation has resulted in the ... -
Wake behavior downstream of a transonic compressor rotor
(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
(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
(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
(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
(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
([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
(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 ...
