A systematic investigation of the effect of interior ballistic parameters on solid rocket propellant exhaust smoke was initiated in a controlled environment smoke measurement facility. Conventional plastisol nitrocellulose composite propellants were used in this investigation. Highly significant effects on exhaust smoke were found for varying interior ballistic parameters such as chamber pressure, mass discharge rate, and expansion ratio. These results are interpreted in terms of aerosol particle size and concentration as functions of time. Motors were prepared and fired outdoors to demonstrate the results of these studies under field conditions.
