A pressure recovery system for chemical oxygen-iodine laser based on an active diffuser. Malkov, V., Kiselev, I., Orlov, A., & Shatalov, I. Thermophysics and Aeromechanics, 18(3):381-395, 2011. cited By 1
Paper doi abstract bibtex An open-type pressure recovery system (PRS) for chemical oxygen-iodine laser was designed and fabricated. As a first stage, an active diffuser was used in which the ejecting gas supply was organized through nozzles disposed around the channel periphery. The second stage was a supersonic ejector. Numerical simulation data for the viscous turbulent flow with heat release through the diffuser gas-dynamic channel, and also data obtained by testing the active diffuser in operation on a model facility equipped with a vacuum chamber, are reported. The obtained data were used to develop a full-scale setup with exhaust of laser gas into the atmosphere; this has allowed us to optimize the performance characteristics of the setup and substantially improve its mass-dimensional characteristics. Special attention was paid to parameter matching and synchronization of laser start with the operation of PRS components. © 2011 Pleiades Publishing, Ltd.
