EPKM
Fourth Academy solid rocket engine. Chinese kick stage for use on CZ-2E for launch of Asiasat-2 and Echostar-1. Diameter increased to 1.7 m in comparison to basic 1.4 m diameter motor. Spin stabilized. First flight 1990. Solid propellant rocket stage. Perigee kick motor for putting CZ-2E payloads into geosynchronous transfer orbit. Thrust, burn time estimated. Specific impulse calculated based on motor payload/delta v performance and masses.
