Shock/Ludwieg-tube driven HF laser
Abstract
A laboratory facility has been constructed for study of the highly-coupled CW HF/DF chemical laser. F2/diluent oxidizer gases are heated at the end wall of a rectangular shock tube and expanded through a screen nozzle to the test section. Unheated H2 fuel is simultaneously supplied to the screen nozzle from a Ludwieg tube. The supersonic streams mix and react downstream, and multimode power is extracted by a simple cavity. The power is repeatable and shows some agreement with a quasi 1-D model under development. Operating features and capabilities of the facility are discussed, and its usefulness for systematic study is indicated.
