Silicon micromachined sensors and sensor arrays for shear-stress measurements in aerodynamic flows
(Aerospace Computational Design Laboratory, Dept. of Aeronautics & Astronautics, Massachusetts Institute of Technology, 1997-02)
In this thesis we report on a new micromachined floating-element shear-stress sensor for turbulent boundary layer research. Applications in low shear-stress environments such as turbulent boundary layers require extremely ...
Airline O-D control using network displacement concepts
([Cambridge, Mass. : Massachusetts Institute of Technology], Flight Transportation Laboratory, [1996], 1996)
In the airline industry, it is customary for carriers to offer a wide range of fares for any given seat in the same cabin on the same flight. In order to maximize the total network revenue, the airline practices so-called ...
The Airline Operation Control Centre : an overview of Garuda's Operation Control (EM) at Cengkereng Jakarta, Indonesia : final report to PT Garuda Indonesia
([Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, 1995], 1995)
Introduction: Airline operations are generally handled in two phases, strategic and tactical. Strategic operations are concerned with schedule planning. Given the desired schedule of services to be offered to passengers ...
Competition between traditional and low-cost airlines for local hub traffic
([Cambridge, Mass. : Massachusetts Institute of Technology], Flight Transportation Laboratory, [1996], 1996)
It is conventional wisdom among informed observers of the U.S. airline industry that the passengers who fly full-service, hub-and-spoke-style, "traditional" airlines like American, United and Delta are significantly different ...
Blade scale effects of tip leakage
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1990], 1990)
The effects of blade-tip leakage in a turbine are investigated by modeling the stage as an incomplete actuator disk. It is found that the spanwise flow redistribution due to the gap is such as to produce a uniform unloading ...
Analysis and design of transonic cascades with splitter vanes
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1991, 1991)
A new computational method, MISES, is developed for turbomachinery design and analysis applications. The method is based on the fully coupled viscous /inviscid method, ISES, and is applicable to blade-to-blade analysis of ...
Dynamic control of rotating stall in axial flow compressors using aeromechanical feedback
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1993], 1993)
Dynamic control of rotating stall in an axial flow compressor has been implemented using aeromechanical feedback. The control strategy developed used an array of wall jets upstream of a single stage compressor which were ...
Blade passage flow structure effects on axial compressor rotating stall inception
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1996], 1996)
A new computational approach has been developed to study the inception of rotating stall in axial compressors. Using this approach the flow structures within the compressor blade passages have been examined in order to ...
Investigation of competitive impacts of origin-destination control using PODS
([Cambridge, Mass. : Massachusetts Institute of Technology], Flight Transportation Laboratory, [1998], 1998)
The Passenger Origin / Destination Simulator (PODS) was used to investigate the competitive impacts of Origin-Destination control airline Revenue Management (RM) methods. Experiments performed included revenue performance ...
Network value concept in airline revenue management
([Cambridge, Mass. : Massachusetts Institute of Technology], Flight Transportation Laboratory, [1998], 1998)
A connecting passenger occupies a seat on each of the flight leg of his itinerary. Moreover, for a given fare class, the fare of a connecting passenger is lower than the sum of the fares of the local passengers on the ...
