Rocketry Planet

A short motor testing session was held at the Cesaroni Technology Incorporated facility in Gormley, Ontario on June 26th, 2009. Thanks to Angelo Castellano for supervising the testing session.

Twenty-seven (27) motors were fired in hardware ranging from the new 29mm diameter Pro29-6GXL, up to the 75mm diameter Pro75. Impulses ranged from G to L and reloads were certified for use in hardware from CTI. Four propellants were fired, adding new products with Classic (CL), Smoky Sam (SS), Skidmark (SK) and Imax (IM).

This session included an “I” variant of the Pro38 5G Classic reload which is a 99% I at 636.1 N-sec.

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. With that in mind, one of these motors includes a note that indicate it is considered high power under NFPA 1125.

I am very pleased to announce the certification of eight (8) new reloads from Cesaroni Technology, Inc. Individual certification letters follow for each motor.

Motors certified:

• CTI 168-H87-IM-12A (CTI Pro29-3G)
• CTI 305-H226-SK-14A (CTI Pro29-6GXL)
• CTI 287-H340-SS-14A (CTI Pro29-6GXL)
• CTI 150-G50-IM-15A (CTI Pro38-1G)
• CTI 286-H100-IM-15A (CTI Pro38-2G)
• CTI 636-I216-CL(I)-14A (CTI Pro38-5G)
• CTI 2772-L640-DT-P (CTI Pro54-6GXL)
• CTI 4828-L1410-SK-P (CTI Pro75-5G)

These letters and the accompanying thrust curves will be available on the official CAR website soon.

I'm looking forward to trying out the full I. Given its longer burn duration, I think it's the most capable motor out there now for the I altitude record.

In the certifications PDF, I made a typo - the Total Impulse for the 636-I216-CL(I)-14A is listed as 63.1N-sec but it should be 636.1N-sec.

Tom, do you have the docs for these posted now? If so, I will in the next couple of days go and get them, and enter them into the Thrustcurve database so we can populate it with motor files.

Hi Mark,

Not trying to answer for Tom but I just had a look and they have been posted on the CAR site. Hopefully this makes it easy to find them. Shane, the CAR Webmaster is VERY organized. Links below. In each case, the PDF is highlighted in the upper right corner of the page just below the name of the motor. Len

I still have a bit of work to do to generate the ENG files, but I'm hoping to start that soon, perhaps this weekend.

WOOHOO more motors, With TMT, CAR MC2,and S&T running overtime how is one going to find the time to fly them all. Looks like the Clubs are going to have to go to 2 weekends a month

I am going to need a second or third job the rate they are certifying new motors and reloads.

What we need to do, is figure out a way to turn flying these motors into the job...

The most recent batch of 8 CTI motors is up on Thrustcurve.org in .rse and .eng formats.
Some great motors on the list for sure.

I agree. But as with a lot of things I do if I had to do it every day it might not be near as much fun.
