Development of A Novel Fast-Actuating Valve For Improved Ludwieg Tube Activation Efficiency

Abstract

This report was developed under a SBIR contract for topic AF161-077. Mainstream has successfully developed a new valve technology for the rapid initiation of flow in hypersonic wind tunnels. The multi-use valve, designed to replace single-use rupture disks, opens to full bore on the timescale of milliseconds. Mainstream has improved the Phase I prototype of the 10-inch fast valve for AFRL's 600 psi, 450F, Mach 6 Ludwieg Tube. We have also developed new sealing technology, which we implemented into the Phase II prototype of a 24-inch fast valve for UTSI's 150 psig, room-temperature, Mach 4 Ludwieg Tube. This report summarizes the development and results of Mainstream's fast-valve technology during Phase II.
