Mach 7 Ludwieg Tube

A Mach 7 Ludwieg tube is currently being constructed at TALon, with a design similar to the Mach 4 Ludwieg tube. The driver tube air will be heated to a temperature of 550 °F and pressurized to an initial pressure of 150 psi. The tunnel will have a fast-valve installed in order to operate without the use of expensive metallic burst discs. The test section will be 18” x 18”, providing a relatively large scale facility compared to most academic tunnels. The close proximity of this tunnel to the Mach 4 tunnel will allow for diagnostics to be easily shared between the two. The facility will be operation in early 2021.
