R74 New Motor Certifications 9 Jul 2001

The following motors have been certified by NAR Standards & Testing for general use as model rocket motors effective March 4, 2001. They are certified for NAR contest use effective August 17, 2001. The delay in this announcement and the contest-use date was to allow labeling modifications to percolate through the distribution chain. They are not certified for contest use at NARAM-43 because NARAM-43 occurs before this date.

The following are Aerotech reloadable motors, certified only with the indicated size casing and manufacturer supplied nozzle, end closures, delays, and propellant slugs.

    Aerotech:
        18mm x 70mm (RMS-18/20 casing):
            D24-4,7 (18.5 Newton-seconds total impulse, 8.8 grams propellant mass)
