An experimental study of the wall characteristics of a local fluid constriction plasma generator
(Virginia Polytechnic Institute and State University, 1973)
A local energy conversion efficiency for a confined-discharge plasma generator is defined as the fraction of local power input which is transferred to the gas. The local efficiency is a maximum near the gas inlet and ...
Testing of the suspended vehicle system scale model
(Virginia Polytechnic Institute and State University, 1973)
A 1/24th scale model of the SVS (Suspended Vehicle System) guideway was constructed, instrumented, and tested. The model simulated five 250-ft-spans of the cable-stayed guideway for high-speed mass transportation type ...
Flight test of a supersonic decelerator on Earth to simulate a Mars entry
(Virginia Polytechnic Institute and State University, 1973)
A systems analysis is presented for simulation of the descent of a decelerator (parachute) and spacecraft for entry through the atmosphere of the planet Mars by a flight test in the Earth's atmosphere. Engineering atmosphere ...
Effect of relative humidity on fatigue of anodized 2024-T351 aluminum in completely reversed torsion
(Virginia Polytechnic Institute and State University, 1973)
A corrosion fatigue investigation was conducted on anodized 2024-T35l aluminum alloy in reversed torsion. The corrosive environment was provided by varying the relative humidity of air around the specimens during fatigue. ...
