Thrust Profile (N)

2.10s Burn Window

Engineered by Raketenmodellbau Klima, the D9 is a 18mm solid rocket motor designed for model rocketry. As an official D-class motor, it delivers a total impulse of 20.0 Ns over a 2.10 second burn window.

With an average thrust of 9.0 N and a peak of 25.0 N, it features a regressive thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the composite propellant formulation, dictating its specific impulse and exhaust signature.
