New Motors certified by Tripoli

Original Source from Rocketry Online

Tripoli Motor Testing certified no less than 13 new motors yesterday, all but one (the L1276) have Sparky effects, and all are reloads.

RR= Red Rhino (red)
SK, SM = Skidmark (Smokey)
SF = Spitfire
WC = Bates Grain White

From Cesaroni for their ProX line:

L1276RR-P
AMW 54-2250 case
1581Ns (6% L) total
2.126s burn time

J520SK-15A
Pro38-6GXL
848.4 Ns (32% J)
1.63s

J250SK-15A
Pro54-2G
628.8Ns (7% J)
2.73s

J395SM
Pro54-3G
1015.9Ns (58% J)
2.78s

Gorilla Motor Works:

J485WC
54-1050 case
1059.7Ns (65% J)
2.19s

K630WC
54-1400
1414.8Ns (10% K)
2.24s

K805WC
54-1750
1765Ns (38% K)
2.19s

Loki Research:

L780SF
75-3500
3006Ns (17% L)
3.83s

K830SF-PS
54-2800
2287Ns (78% K)
2.73s

K690SF-PS
54-2000
1616Ns (26% K)
2.35s

J350SF-PS
54-1200
931Ns (45% J)
2.67s

J650SF-PS (mistakenly listed on above linked post as J750SP)
38-1200
942 Ns (45% J)
1.45s

M1200SF-PS
75-6000
4.485s

The above M1200 has a total impulse of 5122.6 Ns - 2.6 Ns above the M cutoff line and a 0.05% M. It'll be classified as an M until March 21, 2010 ( 1 year from first testing date), then classified again to ensure that it doesn't lose potency - and become a 100% L - after a year on the shelf. If it really is an M, then it's a perfect motor for getting an L3 cert with the smallest / lightest built rocket possible. If not, then it's prefect for setting an L altitude record.

They'll do more testing with new loads in the above casings on the 25th. Stay tuned.

I think it's pretty amazing that they can certify 13 new HPR reloads at once. We low-power folks are lucky to get a handful a year - both the new G80T and F32T together is amazing - and such a new selection is pretty cool. i think this puts the total certified list up to 564. 550 as of the list in Sport Rocketry, plus the F32T and these 13.
