Evaluation of aircraft performance algorithms in Federal Aviation Administration's Integrated Noise Model
(Massachusetts Institute of Technology, 1999)
The Integrated Noise Model (INM) has been the Federal Aviation Administration's (FAA) standard tool since 1978 for determining the predicted noise impact in the vicinity of airports. A review of the aircraft performance ...
Analysis of mixing and thrust diagnostics for shock tunnel hot nozzle testing
(Massachusetts Institute of Technology, 1999)
Transient testing of hot engine exhaust nozzle flows is being pursued to enable cost and time savings of one to two orders of magnitude over steady-state hot-flow testing. This thesis presents the design and assessment of ...
Performance study of flight deck interface systems for air traffic control-pilot data link communications (CPDLC)
(Massachusetts Institute of Technology, 1999)
In an effort to reduce saturation in voice radio channels and to take advantage of space-based communication technologies in a cost-effective basis, data link communication between the flight deck and air traffic control ...
Analysis of nonlinear electroelastic continua with electric conduction
(Massachusetts Institute of Technology, 1999)
This thesis presents the nonlinear theory for large deformation electroelastic continua with electric conduction. This theory is suitable for modeling actuator and sensor devices composed of deformable, electromechanically ...
Micrometeroid, orbital debris, and shielding analysis for the Soft X-ray Camera (SXC) of the High Energy Transient Explorer (HETE-2) spacecraft
(Massachusetts Institute of Technology, 1999)
The High Energy Transient Explorer (HETE-2) is a scientific spacecraft that will carry out a multi-wavelength study to determine the origin and nature of cosmic gamma-ray bursts (GRBs). The Soft X-ray Camera (SXC) is the ...
Microfabricated refractory ceramic structures for micro turbomachinery
(Massachusetts Institute of Technology, 1999)
The MIT Microengine Project was initiated in 1995 as a joint effort between the Gas Turbine Laboratory (GTL) and Microsystems Technology Laboratory (MTL) to develop a MEMS-based micro-gas turbine engine. The thermodynamic ...
Air traffic management and conflict analysis for reusable launch vehicles
(Massachusetts Institute of Technology, 1998)
Increasing demand for commercial utilization of space is accelerating the development of technologies that have the potential of providing safer and more economical access to space. Reusable Launch Vehicles (RLVs) are ...
Aerodynamic response of turbomachinery blade rows to convecting density wakes
(Massachusetts Institute of Technology, 1998)
Density wakes have been recently identified as a possible new source for high cycle fatigue failure in the compressor blades of modern turbomachinery. In order to characterize the density wake induced force and moment ...
Actuator and sensor design and modeling for structural acoustic control
(Massachusetts Institute of Technology, 1999)
The use of a high-fidelity finite element model is investigated for the design and closed loop performance prediction of shaped and distributed sensors and actuators for structural acoustic control. Sensor and actuator ...
Identifying the impact of modeling and simulation in the generation of system level requirements
(Massachusetts Institute of Technology, 1999)
Requirements generation is an influential time in the evolution of the program. It allocates 70% of the life-cycle cost of a program and is responsible for a large percentage of the system errors and cost overruns. This ...
