An Analysis Of The Potential For Using Over-The-Horizon Radar Systems For Space Surveillance, Matthew J. Colbert

Theses and Dissertations

The Australian Defence Force is investigating the development of a space surveillance system. While several dedicated facilities for space surveillance are in operation around the world, Australia s Over-The-Horizon Radar (OTHR) network has some potential for this role. The OTHR operates in the HF band and is constrained by the propagation effects of the ionosphere. A spherically stratified ionospheric model and a model for a nominal OTHR antenna are developed that allow calculation of path propagation, power distribution, and clutter returns. A software-based radar receiver processing system is modeled to determine detection probabilities and the minimum detectable radar cross-section of …

The Cool Flames Experiment: Recent Results At Reduced And Partial Gravity, Michael R. Foster

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Cool flames at Earth (1g), Martian (0.38g), Lunar (0.18g) and reduced-gravity (10–2g) have been studied experimentally in a closed, unstirred, static reactor to better understand the role of natural convection and diffusive transport on the induction period(s), flame shape, flame propagation speed, pressure history and temperature profile. Natural convection is known to play an important role in all terrestrial, unstirred, static reactor cool flame and auto-ignition experiments when the Rayleigh number exceeds 600 [2,3,6]. At 1g, typical values of the Ra are 10^4-10^6.

In this paper, experimental results from static, unstirred reactor studies conducted at four different gravitational acceleration levels …

Rocket Plume Particulate Characterization By Multiple Wavelength Opacity And Mie Scattering, Andrew P. Chouinard

Theses and Dissertations

In the presented work, experiments were conducted to assess the utility of plume opacity monitoring for hybrid rocket diagnostics. The first phase of the work involved measuring plume opacity at a single wavelength and then at two wavelengths simultaneously. Results showed excellent correlation between plume opacity and rocket motor firing cycle and correlation between plume opacity and oxidizer flow rate, thereby validating the utility of the technique. Additionally, a spectral dependence of plume opacity was demonstrated that indicated the possible presence of transparent particulates in the plume. Further phase 1 experiments investigated the performance requirements of a laser-based instrument to …
