solarx - 23/1/2007 2:05 PMany scientists & engineers there..... (^o^)i have 2 more questions:1) Is it possible by launching that 10,000 tonnes rocket, a spacecraft could reach over 108,000 km/h ? (without other planets gravity assistance)2) If yes, we need 7 stages or only 4 stages to reach this goal ?.....thank you.....
JIS - 25/1/2007 5:30 AMSorry, but the cost would be huge. 3rd stage would need engine with higher thrust than RS-68 (Delta IV) and second stage would need engine about thrust of SRB. LOX/LHX 1st stage engine with thrust of 125 MN is simply imposible.........

vda - 25/1/2007 6:00 AM"I am not a rocket science guy. I think that the question is wrong. It's irrelevant whether it is possible, because it's stupid."Fascinating comment...I believe you missed the entire point of the man's question. Could you build this device? Google "multi-engined dragsters" and "Mesabi range locomotives". Land speed attempts have utilized mulitiple engines for decades. I believe that the only obstacle would be the sheer weight of the completed device, and maintaining structural rigidity under the stresses of launch would be a formidable task. The other concern would be how strong and how far the shock wave would travel if it exploded on liftoff. It's been said that the Shuttle contains the same energy that was released by the first atomic weapons. Flattening everything between Jupiter Inlet and Daytona Beach would not be good for public relations, you know!
solarx - 26/1/2007 12:26 AMwe could make 1 huge engine with few combustion chambers & nozzles , it's still possible.
