Thrust Profile (N)

2.45s Burn Window

Engineered by AeroTech, the H55W is a 29mm solid rocket motor designed for high-power rocketry (HPR). As an official H-class motor, it delivers a total impulse of 162.3 Ns over a 2.45 second burn window.

With an average thrust of 55.0 N and a peak of 113.3 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.
