ROL NEWS--AeroTech Announces Certification of Three New Reload Kits

AeroTech Announces Certification of Three New Reload Kits June 22, 2004 Web posted at: 5:40 PM EDT

(ROL Newswire) -- The AeroTech division of RCS Rocket Motor Components (RCS), Inc. is pleased to announce the certification of three new Reloadable Motor System (RMS) reload kits by the Tripoli Motor Testing (TMT) committee. These reloads are the 29mm G79W, 38mm G61W and the 38mm I600R.

Technical specifications may be found on the AeroTech website at

The G79W uses two standard grains from the 29mm high power RMS line, and the G61W uses a single standard 38mm RMS grain. The I600R uses standard length 38mm Redline grains that have been modified to reduce the motor output to just under 640 N-sec. The I600R was specifically designed for use in this year's LDRS 'I-Lite' Bowling Ball loft competition and produces an initial thrust of over 180 pounds with a duration of just under 1.1 seconds.

The two 'G' reloads fit new RMS casings that are being introduced simultaneously by AeroTech and Dr. Rocket/Reloadable Systems. These cases are compatible with existing 29 & 38mm high power closures. The G79W is NOT compatible with the 29/40-120 model rocket RMS hardware. The I600R fits existing 38/720 motor hardware.

The three new reloads are being released in conjunction with LDRS-23, the annual high power rocket launch sponsored by the Tripoli Rocketry Association. Limited quantities of G61W and G79W reloads and 29/120 and

38/120 RMS cases will be available from AeroTech dealers attending the launch. Initial sale of the I600R reloads will be restricted to participants in the I-Lite Bowling Ball Loft competition.

The G79W and G61W reloads qualify as "model rocket motors" and no user certification is required, though purchasers must be 18 years of age or older in compliance with Consumer Product Safety Commission (CPSC) regulations. A Level 1 Tripoli or NAR certification is required for purchase of the I600R reload.

Way to go Gary! So glad to see you back in action! Can't wait to go to LDRS 23.... Barry

Do they go into "outer space" too?

I600R also sounds like a good 'pre-L2 shakedown' motor for L1 flyers IMO.

*Lots* of thrust, but still an I.

Yep - and a step in the right direction IMHO. We have too many motors that are a "baby J" or "baby M" or whatever... it's good to see some that are near the top of the impulse range for their "letter" class.

Yeah, but I'm thinking that my L1 rocket should, all being well, be able to take the 5G Pro38 motor, which is just a 'J', for L2 cert. Seems a bit like cheating, but if you can cert L1 with a saucer...!

Unfortunately it doesnt look like we'll be seeing any AT over here in a hurry though. The Pro38 smoky 5G is just over 600 Ns IIRC.

Yep. But I do not believe any motors are CE approved yet.

Yet you do not like USR (think it should be certified). Ironic, eh?

Hey, I'd love to see you get your motors certified. Just don't expect everyone to set aside the rules just for you. You want 'em certified, you gotta meet the same standards as every other manufacturer. If you are unable do that, I'm sympathetic. If you're unwilling to do that, well, that's your choice.

You mean the same standards that keep very nearly every manufacturer of solid rocket motors in this country _uninterested_ in offering "certified consumer" motors?

It's a shame these two aren't NAR certified. While reciprocity applies to use, it means they are not usable in NAR contest flying. The F21 has the same problem.

Name ONE motor manufacturer besides Frank and Jerry who has specifically cited the motor cert requirements as a reason not to produce consumer motors.

BTW, "well, there was this guy who used to make a few motors for his buddies" doesn't count. You said "motor manufacturers", not small time wannabes.

Sorry Jerry, unsubstantiated claims and wild speculation are not allowed in the FAQ.

Why not start with those two, and their related customers and contractors (totaling over 5 "manufacturers").

Just out of curiosity, why do contest motors have special cert requirements?

Reply to
RayDunakin

What, two isn't enough?

Ray, your attitude sucks AP fumes.

Hobby rocketry is enough of a niche market that we have no freakin' business making a distinction between "small time wannabes" and "manufacturers"... we should be _encouraging_ "small-time" suppliers to come forward with new products - motors as well as books, electronics, rail buttons, or molded plastic hardware for parallel-staged boosters - instead of setting policies intended to keep out those who aren't "legitimate" (i.e., "established" and "corporate") enough.

And don't go bleating about "government requirements" - that's one of the areas in which the orgs could offer help: Imagine if NAR/TRA had an outreach program to assist new manufacturers through the DOT testing process to establish their propellants as "suitable to be shipped safely", instead of simply laying back, arms folded, and saying "go make your own arrangements with DOT and then we'll consider talking to you".

Ray: The only special cert requirement for contest cert is that they will more generally available....

4.9 Contest Approval

NAR Contest Approval shall be granted only to model rocket motors that are currently and readily available commercially,

and that also meet the requirements of Rule 4.1 through Rule 4.8.

requirements?

bob: where does it say that for a model rocket engine to be NAR contest certified it has to be certified as such by only the NAR. The only requirement that I can find for contest cert is this:

4.9 Contest Approval

NAR Contest Approval shall be granted only to model rocket motors that are currently and readily available commercially,

and that also meet the requirements of Rule 4.1 through Rule 4.8.

4.4 Certification

All motors used in a model rocket in NAR sanctioned competition, or for the purpose of establishing a United States Model

Rocket Performance Record, shall be of a type currently holding NAR Contest Approval. No model rocket motor shall be

flown at any NAR Sanctioned activity unless that motor holds current NAR Certification.

It seem by this language that All the NAR has to do is say they are Contest Approved....

I think the idea is to prevent someone from gaining an advantage by using motors that others in the event wouldn't be able to procure. (For example, suppose someone had a stash of the Apogee "mini" motors left over from when they were available...)
