The Tripoli Motor Testing (TMT) Committee of the Tripoli Rocketry Association (TRA) has certified two new AeroTech 54mm and one new 75mm Reloadable Motor System™ (RMS™) ‘K’-class rocket motor reload kits.
The new reloads include the K375NW-P and the K480W-P which are both designed for AeroTech, Dr. Rocket™ or Rouse-Tech™ RMS-54/2560 motor hardware, and the K1000T which fits RMS-75/2560 hardware.
The K375NW is AeroTech’s first 54mm Boost-Sustain™ motor and the latest one to be certified since the 38mm I59WN Boost-Sustain reload was submitted for National Association of Rocketry (NAR) certification in September, 2007. It uses a coreburning Warp-9™ grain placed at the aft (nozzle) end of the motor followed by four coreburning grains using a slower-burning version of AeroTech’s White Lightning™ propellant. Upon ignition, all five grains burn together and produce a boost thrust phase of 300 pounds for slightly over 0.5 seconds until burnout of the Warp-9 grain, which is immediately followed by a sustain burn from the remainder of the White Lightning grains of approximately 80 pounds, for a total burn time of nearly 6 seconds. The effect is remarkable and the transition from boost to sustain can be clearly seen on the test stand and in flight.
The K480T is in the identical form factor as the popular AeroTech K700W reload but uses the slower White Lightning formulation as in the K375NW Boost-Sustain motor. As a result, the K480W burns significantly longer that the K700W, delivering a nearly 4.5 second total burn time with a peak (initial) thrust of 210 pounds and a regressive thrust trace.
The K1000T is AeroTech’s first Blue Thunder™ propellant reload for the 75mm RMS motor line. The motor delivers a reasonably flat thrust profile with a peak thrust of nearly 260 pounds and a burn time of 2.5 seconds. More 75mm Blue Thunder reloads are under development and are planned for release later this year.
Manufacturer suggested retail prices (MSRPs) for the new motors are $159.99 for the K375NW-P (P/N 11375P) $149.99 for the K480W-P (P/N 11480P) and $164.99 for the K1000T (P/N 11100P).
Motor instructions (including thrust curves and other motor data) and assembly drawings for the new reloads are now available for download in PDF format from the AeroTech Resource Library.
