This paper presents a wireless leak detection and localization system, based on airborne ultrasonic acoustics and a fast-Bayesian inference technique. Leaks caused by micrometeoroid and orbital debris are major concerns for mission safety on the ISS and other pressurized space structures. A sensor system was designed and constructed to observe these ultrasonic signals and localize the leak. A novel...
Pressurized space vehicles of all types are at risk of depressurization due to leaking air. This project addresses the issue of leak detection by analyzing airborne noise through Fourier Decomposition and Singular Spectrum Analysis (SSA). Based on the leaking material, size of the leak, and pressure gradient, different sounds will be produced. Once a large amount of these sounds have been recorded,...
