Laser-Induced Diaphragm Rupture for Improved Sequencing and Repeatability in a Hypersonic Facility

Abstract

For a Ludwieg tube facility where the flow is initiated using the rupture of a single diaphragm, the sequencing of free flight model release or other events related to flow onset can be difficult.The challenge of experiment sequencing that arises due to rupture pressure variability is addressed by introducing a laser-induced diaphragm rupture method.
