Thrust Profile (N)

0.86s Burn Window

Engineered by Estes Industries, the B6 is a 18mm solid rocket motor designed for model rocketry. As an official B-class motor, it delivers a total impulse of 4.3 Ns over a 0.86 second burn window.

With an average thrust of 5.0 N and a peak of 12.1 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.
