The objective of the kinetically designed nozzle in-house program was to determine whether an increase in performance could be obtained over present conventional isentropic nozzle design techniques by considering nonequilibrium chemistry effects in the design process. It was structured as a three phase program. Phase I included a parametric study to analytically determine if there was a significant increase in nozzle performance to be gained using the kinetically designed nozzle analytical model for a general multi-component reacting gas. The results of this study would then be used to decide whether to proceed to the next two phases that would entail the fabrication and testing of several nozzles. Unfortunately, the KDN computer program could not be made to work right with the NTOMMH propellant combination and this entire effort had to be terminated short of its original goal.
