Rule-based fuselage and spine and cross-section methods for computer aided design of aircraft components
(Virginia Tech, 1993-05-04)
<p>In recent years, the use of computer-aided design (CAD) systems for conceptual aircraft design has greatly increased. As a result, new and better methods for creating surface models of aircraft geometry using dimensional ...
Intersection and filleting of non-uniform B-spline surfaces
(Virginia Tech, 1991-01-29)
<p>Preliminary aircraft design codes requIre a more complete and integrated geometry definition than that used by conceptual design codes. This thesis documents the design and creation of an interactive CAD system which ...
Reverse parameterization of B-spline surfaces for data transfer
(Virginia Tech, 1993)
This thesis presents the algorithms and methods for transferring B-spline surface data from a final design CAD tool to a parameter based conceptual design CAD tool. Both codes store data in different ways, requiring a ...
The characterization of the flowfield of a dump combustor
(Virginia Tech, 1990-09-05)
<p>To provide quality benchmark data (that can be used in numerical simulation comparisons) and to examine the effects of combustion on a typical ramjet engine flowfield, a water-cooled, stainless steel dump combustor model ...
