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’
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
