Thrust Profile (N)

0.77s Burn Window

Engineered by Quest Aerospace, the A3 is a 18mm solid rocket motor designed for model rocketry. As an official A-class motor, it delivers a total impulse of 2.5 Ns over a 0.77 second burn window.

With an average thrust of 3.2 N and a peak of 8.4 N, it features a regressive thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the Black Max propellant formulation, dictating its specific impulse and exhaust signature.
