A Legendre Pseudospectral Method for rapid optimization of launch vehicle trajectories
(Massachusetts Institute of Technology, 2001)
A Legendre Pseudospectral Method for launch vehicle trajectory optimization, pro posed by Mike Ross and Fariba Fahroo of the Naval Postgraduate School, is presented and applied successfully to several launch problems. The ...
Experimental investigation of an aspirated fan stage
(Massachusetts Institute of Technology, 2001)
This thesis focuses on the use of aspiration on compressor blade design. The pressure ratio can be significantly increased by controlling the development of the blade and endwall boundary layers. This concept is validated ...
Measuring the causes of airline customer dissatisfaction
(Massachusetts Institute of Technology, 2001)
Reengineering metrics systems for aircraft sustainment teams : a metrics thermostat for use in strategic priority management
(Massachusetts Institute of Technology, 2001)
We explore the selection of metrics for the United States Air Force weapon system sustainment team empirically with emphasis placed on the incentive, structural and predictive implications of metrics. We define the term ...
Design of a silicon microfabricated rocket engine turbopump
(Massachusetts Institute of Technology, 2001)
The advances in silicon microfabrication technology suggest the feasibility of high-precision mechanical devices for power conversion. This thesis describes the design of a silicon demonstration turbopump for a micro-rocket ...
Developing a space shuttle experiment for Hall and pulsed plasma thrusters
(Massachusetts Institute of Technology, 2001)
Very little data on Hall and Pulsed Plasma Thrusters has been taken in the hard vacuum of space. The Environment Effects Verifatication experiment is designed to take archival-quality data in space in the plume and far-field ...
Development and analysis of a high fidelity linearized J₂ model for satellite formation flying
(Massachusetts Institute of Technology, 2001)
A systems study on how to dispose of fleets of small satellites
(Massachusetts Institute of Technology, 2001)
Control allocation for the next generation of entry vehicles
(Massachusetts Institute of Technology, 2001)
Control allocation is the process of assigning control responsibility amongst redundant actuators. A control allocation algorithm for an entry vehicle is presented that uses a linear program to optimally specify bounded ...
Design of a silicon carbide micro-hotplate geometry for high temperature chemical sensing
(Massachusetts Institute of Technology, 2001)
Silicon carbide, high temperature, chemical sensors are the next step in chemical detection technology; allowing for the development of low cost, robust, lower power, and widely applicable chemical sensors. SiC offers the ...
