Default Tripoli Motor Testing Committee Certifies AeroTech Metalstorm “Sparky" Motors

AeroTech Information Release

Tripoli Motor Testing Committee Certifies AeroTech Metalstorm “Sparky" Motors


The Tripoli Motor Testing Committee (TMT) of the Tripoli Rocketry Association (TRA) has certified one new single-use high-power motor and three new high-power reload kits using AeroTech’s unique and exciting new "sparky” propellant, dubbed Metalstorm™.



The new motors include the 29 X 124mm single-use HP-G75M, which will be sold in 4, 7 and 10 second delay times, and three RMS™ reload kits, the 38/360 H170M-14A, the 38/720 J340M-14A and the 54/1706 K540M-14A. The reload kits fit AeroTech, Rouse-Tech™ and Dr. Rocket™ RMS hardware, and the single-use HP-G75M will power most popular 29mm-capable kits and all of AeroTech's mid-power kits. The G75M designation includes the "HP-" prefix in anticipation of proposed National Fire Protection Association (NFPA) code language which will classify all sparky motors, including 'G' class and smaller, as "high-power", requiring NAR or Tripoli user certification for purchase and use.

Metalstorm is AeroTech’s latest propellant designed for its single-use and RMS reloadable motors. It has completely different visual, audible and performance characteristics than the other sparky propellants currently on the market. Metalstorm ignites easily and produces a large, brilliant white exhaust plume, a much longer yellow-orange dense spark tail, plentiful white sparks that fan out in flight and an ample volume of white smoke.



Metalstorm’s high density and relatively high specific impulse results in a higher delivered total impulse for a given volume than some other sparky propellants. This characteristic makes Metalstorm "the performance sparky". Motor burn times using Metalstorm propellant are slightly longer than those produced by White Lightning™, but the total impulse is only slightly lower.

Metalstorm motors assemble in an identical fashion to other AeroTech reloads fitting the same hardware. Cleanup is easy with none of the problems plaguing earlier sparky motors.

As with all rocket motors using spark-generating propellants, special precautions must be taken to avoid fires around the launch pad by clearing the immediate area of all combustible materials in accordance with applicable fire and safety codes.

Performance data, specifications and manufacturer suggested retail prices (MSRP) for the new motors and reload kits are as follows:

The HP-G75M motor and H170M reload kit may only be sold to NAR or Tripoli Level 1 or higher certified consumers. The J340M and K540M reloads require Level 2 user certification for purchase.

Additional Metalstorm reload kits in other popular case sizes are under development and are planned for release later in the 2010 flying season.

AeroTech is now taking orders for the new Metalstorm motors and reloads and deliveries to dealers are expected to begin in about two weeks.

Representative thrust curves, certification documents, applicable assembly drawings and instructions will soon be available for download in PDF format from the Resource Library on the AeroTech website at http://www.aerotech-rocketry.com.

Thanks Gary . . . both for the news and the new motors!

"Sparky" motors on overcast days or at dusk are just plain wonderful.

"The HP-G75M motor and H170M reload kit may only be sold to NAR or Tripoli Level 1 or higher certified consumers. "

Well . . . I was planning on re-certifying this summer, to celebrate my 40th year in the hobby. Now I have another reason!
