Pro54® rocket motor hardware is lightweight and robust, consisting of two components; the motor casing and the rear retaining ring.
Manufactured from thin-wall 6061-T6 aluminum tubing with a clear anodized coating for corrosion protection, Pro54® motor cases are lightweight but strong, capable of holding nearly 2500 psi of internal pressure. The forward closure is retained by a formed rim at the head end of the casing. The rear of the casing has precision-machined external threads, and uses a separate threaded ring to retain the reload. The retaining ring can be interchanged between Pro54® cases.
Pro54® motor casings are available in six sizes to fit reloads from J through L class. Please refer to the motor specifications page to see which Pro54® casing is required for each reload. On this page you can download a handy drawing in Adobe Acrobat (pdf) format showing the key dimensions of each Pro54® motor.
Don't forget that you'll need a delay adjustment tool for your Pro54® reloads, unless you use electronic ejection exclusively. The ProDAT-54 tool allows you to reduce the delay time of your Pro54® reload by any amount up to 10 seconds.
