Redesign of the Particle-Impact Shock Tube and Preliminary Data Analysis
Abstract
The particle-impact shock tube (PST) located at The Aerospace Corporation provides a test environment to investigate the ignition resistance of metals in high-pressure, oxygen-rich conditions. It is important to characterize candidate alloys intended for use in rocket engines for their ignition resistance. The PST has recently undergone rebuilding and modifications, namely with a new expansion region and test section made entirely of hardened Monel K500, and the addition of a copper liner in the test section. This redesign provides improvements to both the safety of the experiment, as well as allowing its operation with higher oxygen fill pressures than previously permitted (fill pressures above 2000 psi are now accessible). This report discusses the circumstances that led to the rebuild, the details of the redesign, and a preliminary look at the performance of the PST with the new expansion region and test section.
