Description
The rocket motor is a standard 3 inch proof motor reduced in length to 31 inches by elimination of a cardboard spacer sleeve. The motor consists of a cylindrical steel body, fitted at the head end with a shell ring, which is held in place by eight spring-locked pins. A head obturator is located behind the shell ring. The propellant consists of seven tubular grains of flashless cordite, each grain measuring 1 inches in diameter by 18 inches in length. The igniter leads pass from the igniter along the outside of the grains and end in a two pronged niphon plug. A tail obturator is located aft of the propellant grains, and a venturi is located in the base of the motor. A small bag of silica gel is placed in the venturi as a moisture proofing measure.
