Abstract : A simple relation is derived between the specific impulse and the flow rate of a gas under the reactor operating conditions allowing molecular dissociation of the gas. Utilizing this relation, an optimum variable thrust program to maximize velocity is obtained for a vertically ascending vehicle under the assumptions of constant gravity and zero aerodynamic drag. The advantage of this program is demonstrated by comparison with the usual constant thrust program. (Author)
