Thrust Profile (N)

0.33s Burn Window

Engineered by Estes Industries, the 1/2A6 is a 18mm solid rocket motor designed for model rocketry. As an official A-class motor, it delivers a total impulse of 1.1 Ns over a 0.33 second burn window.

With an average thrust of 3.4 N and a peak of 7.9 N, it features a neutral thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the black powder propellant formulation, dictating its specific impulse and exhaust signature.
