Scramjet Systems Integration for a Dual Mode Scramjet Flight Test
The Hy-V project will conduct the first-ever mode-transition flight-test for a dual-mode hypersonic scramjet, which will occur at approximately 90,000 feet onboard a sounding rocket. At altitude, atmospheric conditions and inlet flow speed will match the flow conditions simulated in the UVA Aerospace Research Laboratory (ARL) hypersonic wind tunnel. Geometric similarity between the wind tunnel ...
متن کاملBackground rejection in schlieren visualization
Schlieren visualization is one of the simplest ways of determining the geometric parameters of an ultrasonic beam generated by diagnostic transducers, and is recommended for evaluating the potential and the limitations of ultrasonic equipment used in diagnostic applications.’ Apart from some special cases, for example, dynamically focused and/or scanned receiving arrays, the shape of the transm...
متن کاملCharacterization of a Dual-Mode Scramjet Combustor via Stereoscopic Particle Image Velocimetry
The following research paper presents an up-to-date status of the testing of a Dual-Mode Scramjet (DMSJ) model which is experimentally operated at UVa’s Aerospace Research Laboratory. The optical technique Stereoscopic Particle Image Velocimetry (SPIV) is applied to the combustor of the DMSJ with a ramp fuel injector configuration. SPIV is utilized to measure the three-dimensional, combusting, ...
متن کاملDesign and Testing of a Dual-mode Scramjet for Optical Measurement Techniques
The following research paper presents an up to date status of the design and testing of a Dual-Mode Scramjet model which is experimentally operated at UVa’s Aerospace Research Laboratory. The demand for application of advanced optical measurement techniques has facilitated the complete re-design of all test sections. The details of the design, analysis, and capabilities of the DMSJ are the focu...
متن کاملApplication of bacteriorhodopsin films in an adaptive-focusing schlieren system.
The photochromic property of bacteriorhodopsin films is exploited in the application of a focusing schlieren optical system for the visualization of optical phase information. By encoding an image on the film with light of one wavelength and reading out with a different wavelength, the readout beam can effectively see the photographic negative of the original image. The potential advantage of t...
