R&D Progress Report and Financial Progress Report for the period 28 March 1987 through 1 May 1987

Abstract

During April WJSA interacted with NRL on the previously developed approach for examining the effect of autozoom on DF Pulsed Chemical Laser (PCL) performance as it applied towards investigating the Boeing RPDF configuration, including the illumination profile that Boeing measured in RPDF. The key questions addressed were: To what extent is autozoom a problem in a 40 cm initiation height device? Would the F2 profile Boeing selected serve to achieve the goal of a uniform D2+ F2 burn throughout the cavity? Are there other performance robbing process associated with non-uniform initiation? To answer those questions an approach had been developed to model the three dimensional illumination intensity distribution within the gain medium, first without, and then with fluorine present; both in an untailored uniform 16 percent concentration, and in a tailored profile with a 16 percent average fluorine concentration.
