SkyR K347B

Engineered by Sky Ripper Systems, the K347B is a 54mm solid rocket motor designed for high-power rocketry (HPR). As an official K-class motor, it delivers a total impulse of 1529.0 Ns over a 3.57 second burn window.

With an average thrust of 388.0 N and a peak of 1901.0 N, it features a regressive thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the ABS/B, 1130cc nitrous propellant formulation, dictating its specific impulse and exhaust signature.
