INTERNAL ENVIRONMENT OF SOLID ROCKET NOZZLES.
Abstract
A study was conducted of solid propellant rocket motor nozzle environment to implement nozzle design methods. Cold flow studies with models plus hot firing tests for particle impingement and particle cloud radiation are to be used to characterize heat flux rates throughout the nozzle. This report describes the hardware buildup and schedule of heat flux tests on a molybdenum nozzle with hydrogen, oxygen, water, and varying amounts of alumina. Cold flow technique development has shown interesting particle impingement effects as a function of modeling system design and nozzle shape. The implied full scale particle impingement rates are listed for the first two cases studied. A complete report is given on a program studying radiation of a hydrogen-oxygen-alumina plume from a one-inch diameter throatless engine. High emissivity values are indicated for all but the smallest engines. (Author)
