 CEDAR CITY, Utah USA — The Tripoli Motor Testing (TMT) committee of the Tripoli Rocketry Association has certified two new high-power RMS™ reload kits using AeroTech's "Warp-9" propellant, the 38mm I1299N-P and the 75mm K1499N-P.
The I1299N-P generates the highest thrust ever produced by an 'I'-class hobby rocket motor, exceeding 330 pounds. The K1499N-P is perfect for use as a short, high-performance booster in a multi-stage rocket, developing nearly 430 pounds of thrust. Delivered specific impulse (propellant performance efficiency) was measured at 224.6 seconds for the I1299N-P and 223.1 sec for the K1499N-P.
| Reload kit designation | I1299N-P | K1499N-P | | Part No. | 09129P | 11149P | | RMS hardware designation | 38/480 | 75/1280 | | TMT total impulse (N-sec) | 423 | 1,322 | | TMT burn time (sec) | 0.32 | 0.88 | | Propellant weight (g) | 192 | 604 | | Loaded motor weight (g) | 422 | 1,741 | | Retail price | $49.99 | $129.99 |
Warp-9 reloads are currently sold in a plugged configuration because of the tendency of Warp-9 propellant to occasionally "snuff out" a delay charge, due to the extremely fast chamber pressure decay rate. Rockets using Warp-9 motors must employ a timer, altimeter or radio-actuated recovery system. AeroTech is now accepting orders for the new Warp-9 reloads and anticipates shipments to dealers to begin in January. Rouse-Tech has the new 75/1280 hardware needed for the K1499N-P in stock and available for immediate delivery. TMT certification documents, assembly drawings and motor instructions for the I1299N-P and the K1499N-P may be downloaded in PDF format from the Resource Library on the AeroTech website at http://www.aerotech-rocketry.com/.
