SkyR K257G

Engineered by Sky Ripper Systems, the K257G is a 54mm solid rocket motor designed for high-power rocketry (HPR). As an official K-class motor, it delivers a total impulse of 1733.0 Ns over a 6.10 second burn window.

With an average thrust of 282.0 N and a peak of 2461.0 N, it features a regressive thrust curve optimal for heavy rockets requiring high off-the-pad acceleration. It utilizes the ABS/G, 1130cc nitrous propellant formulation, dictating its specific impulse and exhaust signature.
