Abstract:

The measurement of the specific impulse delivered by small quantities of propellant in rocket motors of conventional but miniature design by means of a pendulum system was examined. The rocket motors were assumed to contain on the order of 10 g of propellant. Emphasis was placed on short pendulums for which the propellant burning time could not be neglected with respect to the pendulum period. A mathematical model of the pendulum was used for a design study. An error analysis was made which indicated that the total impulse delivered to the pendulum could be measured to within at least 1 s.d. Analysis of a prototype pendulum design indicated that performance should be satisfactory. A cost estimate of the system was made. Author
