朱雀-2E Block 2 | 2 x SatNet DTC test satellites

描述

Zhuque-2E (E stands for “enhanced”) is a medium-sized rocket powered by liquid oxygen and methane capable of lifting 6,000 kg of payload into a 200 km low Earth orbit, or 4,000 kg of payload into a 500 km Sun-synchronous orbit. It differs from the baseline Zhuque-2 in using enhanced TQ-12A engines on the 1st stage with higher thrust and specific impulse than the original TQ-12, and a new TQ-15A engine on the 2nd stage that has a moveable nozzle. The Block 2 variant lengthens the 1st stage with more propellant load and a lighter structure, plus engines with still more increased thrust to reach the capabilities listed above.

朱雀二号增强型（Zhuque-2E，E 意为“enhanced”，增强）是一型中型火箭，以液氧与甲烷为推进剂，近地轨道（200 公里）运载能力 6,000 公斤，太阳同步轨道（500 公里）运载能力 4,000 公斤。它与基线型朱雀二号的不同在于：一子级采用增强型 TQ-12A 发动机，推力与比冲均高于原 TQ-12；二子级采用新型 TQ-15A 发动机，配备可动喷管。 Block 2 型通过加长一子级、增加推进剂装载并减重结构，再加上推力进一步提升的发动机，达到上述能力。
