Identification of leading indicators for producibility risk in early-stage aerospace product development
(Massachusetts Institute of Technology, 2015)
Producibility is an emergent property of product development and manufacturing systems that encapsulates quality, product compliance, cost, and schedule. Detailed product definition and process variation have traditionally ...
Development of an autoland system for general aviation aircraft
(Massachusetts Institute of Technology, 2012)
Accidents due to engine failure, pilot disorientation or pilot incapacitation occur far more frequently in general aviation than in commercial aviation, yet general aviation aircraft are equipped with less safety-enhancing ...
Boost through reentry trajectory planning for maneuvering reentry vehicles
(Massachusetts Institute of Technology, 2008)
New trajectory planning concepts are explored for rapidly planning a long range, boost-through- reentry mission, using a lightweight, highly maneuverable reentry vehicle. An Aimpoint Map, a set of all possible piercepoints ...
Water waves over a muddy seabed
(Massachusetts Institute of Technology, 2008)
A generalized viscoelastic model is used to describe the rheological properties of mud and is fitted to the available experimental data, so that its constitutive coefficients are just material properties independent of the ...
Computation of upper and lower bounds in limit analysis using second-order cone programming and mesh adaptivity
(Massachusetts Institute of Technology, 2004)
Limit analysis is relevant in many practical engineering areas such as the design of mechanical structures or the analysis of soil mechanics. Assuming a rigid, perfectly-plastic solid subject to a static load distribution, ...
The propagation of errors in the numerical solution of Markov models
(Massachusetts Institute of Technology, 1989)
Asymptotic solution of the Botzmann-Krook equation for a reacting mixture of gases
(Massachusetts Institute of Technology, 1989)
Image collection optimization in the design and operation of lightweight, low areal-density space telescopes
(Massachusetts Institute of Technology, 2008)
Demand for space imagery has increased dramatically over the past several decades. Scientific and government agencies rely on Earth-observing space assets for a variety of functions, including mapping, agriculture, and ...
Assuring safety in high-speed magnetically levitated (maglev) systems : the need for a system safety approach
(Massachusetts Institute of Technology, 2008)
Magnetic levitation is a railway technology that enables vehicles to be magnetically suspended above their tracks. Although this technology is still under development, magnetically levitated (maglev) systems have great ...
System architecting of a campaign of earth observing satellites
(Massachusetts Institute of Technology, 2008)
Given the current level of concern over anthropogenic climate change, and the ongoing debate worldwide regarding what action should be taken to reduce and reverse future warming, the ability to collect data on Earth system ...
