BLACK ROCK DESERT, Gerlach, Nevada USA — Tripoli Motor Testing announced yesterday the official certification of the Cesaroni Technology/Black Sky Pro38 rocket motors. These will be added to the TMT Certified Motor List and to the TMT web pages as soon as possible. These motors are certified for three years and are not due for recertification until July 1st, 2003.
137G60-12A
265H110-13A
402I170-15A
540I240-15A
670J300-15A
800J360-15A
These are 38mm reloadable motors with 1, 2, 3, 4, 5 or 6 propellant grains. The "-12A, -13A, -15A" suffixes designate the delay module used with that motor. The motor comes with the correct delay module already in the packaging. The delay module may be adjusted to one of five different delays per the manufacturer's instructions and the included delay chart. The motors may also be used with electronic ejection per the manufacturer's instructions.
Each motor comes complete with a 1.3 grams black powder ejection charge and an electric match. Absolutely no augmentation of the electric match is needed. According to TMT chairperson, Sue McMurray, "These motors light immediately with just the included bare match."
