Need help with regards to reading the thread in the sticky https://forum.nasaspaceflight.com/index.php?topic=30673.0There is a list of orbital launches there. Figured out most of the fields (please correct me if wrong) except the two fields coloured red. What does those two fields represent? I guess the second one is the launch timing, but what is the format...can't figure it out. <sequence> <(99-99)> - <launch vehicle> <(factory serial no.)> - <launch date> <(9999:99.999)> - <launch site>, <launch pad> - <payload>Btw, the (factory serial no.) is something i just made up. Another thread describe this as a factory number/serial number. What would be the correct descriptor for this number?..2015205 (07-63) - CZ-3C/YZ-1 (Y11/Y1) - March 30 (1352:30.598) - XSLC, LC2 - Beidou-3 I1 (BDS I1-S)206 (05-46) - CZ-4C (Y30) - June 26 (0622:043.731) - TSLC, LC9 - GF-8207 (07-64) - CZ-3B/YZ-1 (Y26/Y2) - July 25 (1229:04.411) - XSLC, LC2 - Beidou-3 M1-S (Beidou-18); Beidou-3 M2-S (Beidou-19)208 (07-66) - CZ-3B/G2 (Y32) - September 12 (1542:04.418) - XSLC, LC2 - Tongxin Jishu Shiyan Weixing-1209 - CZ-2D (Y21) - September 14 (0442) - JSLC, LC43/603 - Gaofen-9
My browser alarms me that the 9ifly.cn forum is now regarded as a Reported Attack Page. Is there a real threat?
Someone has posted a Chinese paper that resolves all configuration discrepancies between the different rockets of the CZ-3A series. :)Basically:CZ-3A - just the one sub-variantCZ-3B:standard version - the original CZ-3B as flown in 1996, with standard length first stage and boosters, uses the 4.0 m diameter 4000F fairingCZ-3B/G1 - standard version CZ-3B with the 3.7 m diameter 3700Z dual-payload fairing, only used for the dual COMPASS MEO launches in 2012CZ-3B/G2 - the original enhanced CZ-3B, with lengthened first stage and boosters, uses the 4.0 m diameter 4000F fairing, first flown in 2007CZ-3B/G3 - enhanced CZ-3B with the 4.2 diameter 4200F fairingCZ-3B/G2 and G3 corresponds to what we call the "CZ-3B/E".CZ-3C - currently just the one sub-variant, with standard length first stage and boosters, uses the 4.0 m diameter 4000F fairing (contradictory to what I said earlier, the CZ-3C as flown today do not use the lengthened first stage and boosters , but see below)The problems with the different stage configurations (e.g. the pad at Xichang requires mating/de-mating of electric cables and gas ducts on the umbilical arms every time between launches of a CZ-3B/E and a CZ-3C) means that there's a need to standardize the launcher configurations. The "standard length" boosters will be phased out in the near future, leaving these mainstay sub-variants:CZ-3B/G2 (GTO capability 5.5 tonnes)CZ-3B/G3 (GTO capability 5.4 tonnes)CZ-3C/G2 ("CZ-3C/E", or CZ-3B/G2 minus two boosters) (GTO capability 3.9 tonnes)plus these special variants:CZ-3B/G3Z - enhanced CZ-3B with the 4.2 m diameter 4200Z fairing and extra RCS tanks and thrusters on the 3rd stage, probably for extra-long coast missions. May debut on the Chang'e 3 launch later this year. GTO capability 5.2 tonnes.CZ-3C/G3Z - CZ-3B/G2 minus two boosters. GTO capability 3.7 tonnes.CZ-3B/YZ-1 - enhanced CZ-3B with the 4.2 m diameter 4200Z fairing and the planned GEO direct insertion upper stage (probably the one using RP-1/H2O2 fuel as exhibited in various aerospace exhibits over the past several years), will be used for future COMPASS system launchesCZ-3C/YZ-1 - CZ-3B/YZ-1 minus two boosters, will be used for future COMPASS system launchesMaybe someone can help to check which launch uses the sub-variants as described above? ;)
