Abstract : The second phase of an experiment to evaluate an extrusion-coating process for inhibiting rocketpropellant grains with ethylcellulose is described. The objectives of this phase of the experiment are to apply a set of chosen operating conditions in the 2 1/2-inch extruder and to consider the effect of eight additional process factors on the quality and dimensions of the inhibited propellant grains. Data resulting from these applications are presented in tabular and graphical form, and an interpretation of the data is included in the text. (Author)
