2.00s Burn Window

Engineered by AeroTech, the H70W is a 29mm solid rocket motor designed for high-power rocketry (HPR). As an official H-class motor, it delivers a total impulse of 215.0 Ns over a 2.00 second burn window.

With an average thrust of 70.0 N and a peak of 174.0 N, it features a regressive thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the White Lightning propellant formulation, dictating its specific impulse and exhaust signature.
