There are two many parameters. Tell me which are the main parameters of your interest. I can dig it out for you.
The CZ-2D is a two-stage, liquid-propellant launch vehicle designed mainly for Low Earth Orbit (LEO) missions, with an LEO payload of 3,700kg. A total of 10 launches were carried out between 1992 and 2008, all from the Jiuquan Satellite Launch Centre.The CZ-2D is generally carries UDMH/N2O4 for all stages. The first stage uses a YF-21B motor consisting of four 65,000kg-thrust YF-20 chambers motors with swinging nozzles. The second stage has a YF-24F rocket motor consisting of one 75,000kg-thrust YF-22B main motor with fixed nozzles, and a YF-23F swivelling venire motor with four chambers motors that produce a total thrust of 4,700kg. The launcher also features a McDonnell Douglas (now Boeing Aerospace) PAM-D upper stage providing 66,700 lb of thrust.The ChangZheng 2D is available in two versions: Type A with a 2.90m-diameter fairing and Type B with a 3.35m-diameter fairing.
2. Does anyone have any specific information on the CZ 4C's third stage? Like number of chambers, thrust, burn time & lsp? And what are the main differences with the CZ 4B's third stage?
About the CZ 2D, CGWIC says it has a YF-21C engine on the first stage and YF-24C on the second stage, Sinodefence says YF-21B on the first stage and YF-24F on the second stage. Which one is right?
I'm looking for CZ-2E images, mainly any images related to the January 25, 1995 Apstar-2 launch failure.Thanks!
Is it possible to identify when this two CZ-2C were launched?
Finally an image from the August 1988 launch.
