Rocketry Planet

GORMLEY, Ontario CAN — Thomas Raithby, chair of Canadian Association of Rocketry Motor Certification Committee, announced today the certification of 52 new motor reload kits for Cesaroni Technology, Incorporated and AMW Pro-X, including the much anticipated new Pro29 line of motors in one through six grain variants, six new AMW Pro-X 54mm reloads, a new Imax propellant, the new Pro54 I445 Vmax one grain motor, and two newly cross-certified Pro75 M motors that also fits the AeroTech 75-6400 RMS™ hardware:

I am very pleased to announce the certification of 52 new reloads from Cesaroni Technology, Inc.

A motor testing session was held at the Cesaroni Technology Incorporated facility in Gormley, Ontario during the dates of April 30th to May 1st, 2009. A total of 208 motors were fired in hardware ranging from the new 29mm diameter Pro29, up to the 162mm diameter Pro150. Impulses ranged from F to O and reloads were certified for use in hardware from CTI, AMW/ProX and Aerotech.

Ten propellants were fired, including Classic (CL), Smoky Sam (SS), Vmax (VM), White Thunder (WT), Blue Streak (BS), Skidmark (SK), Red Lightning (RL), Blue Baboon (BB), Wild Wolf (WW), and a new release – Imax (IM).

An interesting development during this round of testing was submission of two very similar reloads. Two versions of the Pro29-3G Blue Streak reloads were certified. The first was certified as an H133 (see p12) and the second as a G118 (see p21). The H- and G variants of this motor use different nozzles, but are otherwise the same components.

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, several of these motors include notes that indicate they are considered high power under NFPA 1125.

Attached are the certification letters for these new motors. These letters and the accompanying thrust curves will be available on the official CAR website soon.

I wish the best of success to Cesaroni Technology as they continue to expand their selection of rocket motors.

Respectfully submitted,

Thomas Raithby
Chair of CAR Motor Certification

26 motor certs a day??? Wow! How many motor firings does this represent??? (EDIT - 208 motors were fired per the article)

Article states 208 motors were fired. That's a lot of motor!

Mea culpa - I have edited my original reply and taken the fall upon the sword.

If we assume that testing only happened during daylight hours and there are 16 hours of daylight(may be a wee bit high for Canada this time of year) then we have 13 motors per hour or one motor every 4 1/2 minutes. That is a truely staggering number.

I would be very interested in watching the next round of certification testing. With CTI having the ability to broadcast/webcast the testing sessions that are held at the CTI site, would it be possible to setup a video chat session here on RP with the video feed from the testing session? I'd understand if the data feed was not included but the ability to see a well run testing session might shed some light on all the efforts our testing groups go through for us.

Yes, that would be possible, providing it is a true video feed from an encoder. Be a long chat session.

With people assisting in motor prep and given the number of casings involved I think you could maintain this rate with any motor system currently available. The question is how many people took place and how were the shots organized. Someone did a great job managing this event.

I myself have largely moved to using Pro38/AMW-Pro-X's at my home field because of the ease of use. Being a club officer it's hard to get much time to assemble reloads - what little time I get is often interrupted so concentrating on putting a motor together is difficult. I still fly plenty of other motors but mostly when I am attending a launch where I have little to no responsibility for operations.

If CTI/AMW Pro-X motors got any easier to use, Anthony would show up and prep the recovery system for you. Paul already shows up and presses the button.

Amen. I have made converts out of people in the field.

Quote:

How long will it take to prep that motor?

Quote:

About 30 seconds...

Quote:

No way!

Quote:

I'm done. Wanna see me do it again?

Followed by successful flight and recovery - then the inevitable question:

Quote:

How long will it take to CLEAN that motor?

Quote:

About 10 seconds...

Quote:

No way!

Quote:

Edit - I do not time myself in the field this is what it seems like. The times do not include removing the motor from the rocket, or attaching any type of motor retention.

We tested for 5 days. Around 90 motors first day (which was 3/4's of a day). Then about 45, then 20, then 10 and then the balance. Larger motors take progressively more time. We worked from about 8:30 to 6 each day. Everything was well prepared and all the data templates/spreadsheets ready to go.

We used a minimal amount of hardware. For the 29's we used two casings. One in the hand, one on the thrust-stand.

The longest holdup? Waiting for the ejection delay timings. On some motors, like -17A, that is 17 seconds of doing nothing.
