Expansion tube

An expansion tube is a type of impulse facility that is conceptually similar to a shock tube with a secondary diaphragm, an expansion section, a test section, and a dump tank where the endwall would be located in a shock tube.[1] It is typically used to produce high enthalpy flows for high speed aerodynamic flow and aerodynamic heating and atmospheric reentry testing.
