Well, you never know where you got new info for Chinese spaceflight things..... Someone got a presentation that CASC made while trying to find sponsorship for the first flight of the Long March 8, which according to this will fly from Wenchang in Late December 2020.pic.twitter.com/MptuaAixNm
For those who are confused by all those new Chinese rockets, the LM-8 uses the current LM-7 1st stage (2 x YF-100 RP-1 engines), 2 of the current LM-7 boosters (1 x YF-100 RP-1 engine each), and the current LM-3 series 3rd stage as its 2nd stage (2 x YF-75 LH2 engines).pic.twitter.com/8yabKoy3Of
Updated data for LM-8 is as follows: * Length 50.34 m, TOW ~356 tonnes, liftoff thrust ~480 tonnes * Payload capability to LEO/700 km SSO/GTO (t): 8.1/5.0/2.8 (for comparison: Soyuz/Fregat at Kourou 7.6/4.5/3.25, Antares 23X 7.8/3.4/2.5, Falcon 9 in RTLS mode ~13/~8.0/~3.5)
(Soyuz and Antares figures via user manuals from Arianspace and Northrop Grumman, Falcon 9 is from NASA LSP's performance calculator with some extrapolations since the figure given for F9/FH there is incomplete)
The indent settings of the text drive me crazy.
Is that a variant with no side boosters pictured in the bottom slide?
I thought this was supposed to use SRBs as well as the RP-1/LOX second stage of the CZ-7 (powered by YF-115s)?
What you mention is the competitor to the LM-8, the Long March 6A (performance is a bit vague at this point but it's around 4 tonnes to SSO). It and LM-8 will be the main "Antares-Soyuz-Delta II class" Chinese rockets of the future. First flight is by early next year apaprently.
Is it reusable as planned?
Planned I suppose.
i am interested to know if re-usable too
Some say it *will* be but not now?
