Design and Calibration of a Novel High Temperature Heat Flux Sensor
(Virginia Tech, 2005-02-16)
Heat flux gages are important in applications where measurement of the transfer of energy is more important than measurement of the temperature itself. There is a need for a heat flux sensor that can perform reliably for ...
Adaptive Control Methods for Non-Linear Self-Excited Systems
(Virginia Tech, 2001-08-28)
Self-excited systems are open loop unstable plants having a nonlinearity that prevents an exponentially increasing time response. The resulting limit cycle is induced by any slight disturbance that causes the response of ...
Dynamics and Control of Membrane Mirrors for Adaptive Optic Applications
(Virginia Tech, 2008-09-02)
Current and future space exploration operations rely heavily on space-borne telescopes, of which mirrors are an integral component. However, traditional solid mirrors are heavy and require a big storage space. Deploying ...
Optimization of multiple chiller systems
(Virginia Polytechnic Institute and State University, 1984)
Design, Test, and Evaluation of a High Powered 4 DOF Prosthetic Leg for Transfemoral Amputees
(Virginia Tech, 2019-07-01)
A high powered 4 DOF prosthesis for transfemoral amputees is presented in this paper. The prosthesis utilizes series elastic actuators with high powered hobby grade helicopter motors capable of providing 2880~W of power ...
Shock wave end wall boundary layer interaction in a transonic compressor rotor
(Virginia Polytechnic Institute and State University, 1987)
The passage shock wave end wall boundary layer interaction in a transonic compressor was investigated with a laser transit anemometer. A two stage transonic compressor designed without inlet guide vanes was used in this ...
A Process for Manufacturing Metal-Ceramic Cellular Materials with Designed Mesostructure
(Virginia Tech, 2015-03-09)
The goal of this work is to develop and characterize a manufacturing process that is able to create metal matrix composites with complex cellular geometries. The novel manufacturing method uses two distinct additive ...
Performance tests and cooling effect distribution of the V.P.I. forced draft cooling tower
(Virginia Tech, 1939-05-15)
<p>Test data of forced draft cooling towers is all too meager, and that available is, in many instances, incomplete. It is the opinion of the authors that putting cooling tower design on a rational basis can be brought ...
Development and Improvement of Active Vehicle Safety Systems by Means of Smart Tire Technology
(Virginia Tech, 2013-09-20)
The dynamic behavior of a vehicle is predominantly controlled by the forces and moments generated at the contact patch between the tire and the road surface. As a result, tire characteristics can dramatically change vehicle ...
An experimental study of the wall characteristics of a local fluid constriction plasma generator
(Virginia Polytechnic Institute and State University, 1973)
