Paper Abstract

The DLR successfully operates a supersonic chemical oxygen iodine laser (COIL) at power levels of up to 8 kW. We address substantial discrepancies between the measured oxygen yield and its theoretically deduced value. This major issue cannot be resolved by using the well-known heuristic model for COIL performance evaluation. Therefore, a new approach derived from a comprehensive enthalpy flow model is presented and validated. We conclude that the experimental yield value is consistent with the new model whereas the theoretical yield is largely overestimated.
