Today Aerotech announced the certifcation of some cool stuff by Tripoli Motor Testing.
The first is the 38mm spacer system. No surprises there.
The next is the N3300R-P. It's a huge Redline with 14041 Ns total impulse for the 98/15360 hardware. The reload alone costs $798.99 !!! Thrust Curve
The next two are Karl E. Baumann signature motors. They use a version of Blue Thunder propellant that's got an Isp (specific impulse) of 224 seconds, one of the highest ever tested. There's the M1780NT for the 75/5120 casing (3.1s, 5783 Ns) and the M1845NT for the 98/7680 (4.4s, 8308 Ns). The NT indicates the modified Blue Thunder propellant. Prices are $239.99 for the M1780NT and $428.99 for the M1845NT. M1780NT thrust curve; M1845NT thrust curve
Next is the J99N, which I blogged about last month as being an in-testing motor. It's for the 54/852 case, not the 1280 Ns case as previously reported. It's got 945 Ns total impulse over a burn time of 10.3 seconds. It requires the use of a new 54mm aft closure that accomodates 29mm and 38mm nozzles ($39.99) and a forward bulkhead plug ($19.99). The new closure will be used soon on more new and redesigned 54mm reloads. Suggested price is $79.99; thrust curve here and assembly drawing here.
Finally comes a completely new motor case: the 38/1320 case. It's 23" long and designed to hold 11 grains; it'll retail for $89.99. There's also a new reload for it - the J510W. It's got 1162 Ns impulse and a burn time of 2.2 seconds; it strangely uses 6 long fuel grains in the 11 grain case. Suggested retail price is $79.99. thrust curve
I like these. 5 new HPR reloads, including a huge Redline, three high-impulse-blend motors, and a completely new motor case, closure, and spacer system, all released in one day. Props to Gary Rosenfield and the rest of the Aerotech team.
