The designation CZ-2F/H is no longer used and is now the CZ-7. This kerosene liquid oxygen series of boosters in all cases are to do the building block technology demonstration path finding hard development work for the benefit of the Long March-5 medium heavy lift booster series.
LM-2F/H Manned & Unmanned SLV
The LM-2F/H ["H" stands for Huàn or "change" of fuel from N2OH/UDMH to LOX/kerosene] launch vehicle will be used primarily for manned launch of the full Shenzhou spacecraft with its emergency launch escape tower. This will give the booster a payload capacity on the order of between 11.2 -12.5 metric tones to low earth orbit with a launch mass on or about 582 metric tons. Carrying the launch escape tower renders a serious payload capacity penalty for this booster utilized for manned flight. The unmanned version of the booster will have a payload capacity of 13 metric tones. This booster series has had its entire inertial guidance and flight avionics control systems totally redesigned for greater accuracy and safety. The two stage core will remain the same 3.35 meters in diameter utilizing two YF-100, 120 ton thrust engines in the first stage while the second stage is perhaps utilizing a single altitude version of the YF-100 kerosene liquid oxygen engine on the second stage or alternatively a liquid hydrogen, liquid oxygen stage utilizing one or two 50 ton thrust YF-77 engine. The four strap-on boosters will be 2.25 meters in diameter utilize a single 120 tons thrust YF-100 kerosene liquid oxygen propellants engine. That gives it a total liftoff thrust on the order of 720 metric tons. The overall length is planned to be 57 meters. Its first flight test was initially expected in the 2009-2011 time period.
