Abstract
The chemical oxygen iodine laser (COIL) is the most efficient and the shortest wavelength high-energy chemical laser. In this paper, a comparative study of the lasing power for transonic and supersonic injection schemes was performed. It shows that for supersonic mixing the output power and chemical efficiency are about 20% higher than for transonic mixing scheme. The maximum power for the supersonic mixing scheme is obtained for operation conditions of the ejector COIL when the secondary gas flow rate is about two times larger than the primary gas flow rate.
