New Motor Certifications (October 26, 2012)

Postby Thomas Raithby » Fri Nov 16, 2012 11:56 am

A motor testing session was held at the Cesaroni Technology Incorporated facility in Gormley, Ontario on October 26th, 2012. Thanks to Angelo Castellano for supervising the testing!

Three motors were tested and certified:
• Pro38-5G 567-I125-WH/LB-10
• Pro98-4G 8634-M6400-VM-P
• Pro98-6GXL 21062-O3400-IM-P


In addition, an extended retaining ring (called an adapter ring, Cesaroni Technology part # P98-AR) and matching boat-tail (Cesaroni Technology part # P98-BT) were test fired. The adapter ring can be used in place of the standard Pro98 retaining ring where desired (functionally equivalent for the motor). This new boat-tail was designed for the larger XL-style nozzles only.

Note: From a motor testing / safety perspective, the boat-tail can be used with smaller nozzles, however users should consider it ‘single-use’ :shock: for that purpose. Use of the boat-tail with smaller nozzles is expected to cause damage to the boat-tail (exposure of the aluminum boat-tail to the rocket exhaust).

This session included eight motor firings, consumed 31.55 Kg (69.41 lbs.) of propellant, and imparted 61,659.8 N-Sec of impulse.

While these motors were certified in Canada, a reciprocal agreement between the Canadian Association of Rocketry, the Tripoli Rocketry Association and the National Association of Rocketry means they may be flown in many jurisdictions.

I am very pleased to announce the certification of these new reloads from Cesaroni Technology, Inc. A simulation file will be prepared, and the official certification letter and the accompanying thrust curve will be available on the official CAR-ACF website soon.

Respectfully submitted,


Thomas Raithby
Chair of CAR Motor Certification
