NARAM 52 HPR Contest

[Rocketjoe13]

Intrigued by the possibilities. NAR HPR Sporting Code events including a single flight predicted altitude - closest to one mile. Only one flight permitted. I like the Pike's Peak or Bust idea - two or more flights, any impulse, same rocket closest to 14,110 ft accumulative altitude. And the "I" Altitude contest borrowed from UROC's "I in the Sky" idea from a Hellfire launch a few years back. Should be a lot of fun on the Sport range this year.

For the I altitude, the OOP Aerotech I65 would seem like the motor of choice if you are lucky enough to have one in your stash.

Unfortunately, the I65 isn't actually an I motor, as it has 665N*s TMT rated impulse, or a 4%J, so for competition purposes, it is a J motor.

Yeah, I've seen the TRA designation as a J66 for this motor, but the NAR has it certified as 630 N-sec. I figured the NAR designation would apply to NAR contests. :confused2:

I looked it up on the combined NAR-TRA-CAR list (this is what would be used for HPR Contests, because you can use any motor that is certified by any of the three orgs.) and it is listed as 630.5N*s. Moot point anyways since it's OOP.

I've got 2 of them left over from 1987, now what to use them in?

Those are as old as the I132 I have stashed away
Actually, I expect the I132 would be a better altitude motor as it's 38mm instead of the I65's 54mm.

Normally yes, but the contest requirs a section of 4 inch diameter body, so the motor diameter does not really come in to play.

Pike's Peak. Climbed it once from the south side - nice long hike. Disappointed when we reached the peak especially since there's a parking lot and restaurant and too many other ways to reach the summit. Still a pretty majestic view. Trying to decide the best bang for the buck to acheive the required altitude 14,110' without going over or breaking the bank.
