John, can we have approximate figures for the planned X Prize flight of the Armadillo vehicle?
The numbers I currently have are the following: tank volume - 850 gallons tank weight - 1 lb per gallon thrust - 4 engines, 1000 lbf each acceleration time - 95 seconds confirmed Isp - 140 s >From above, the take-off fuel weight should be about 2700 lbs, tank weight - about 850 lbs. And the total thrust of 4000 lbs... the mass budget doesn't seem to be right. What am I missing? Thank you very much, Alexander __________________________________ Do you Yahoo!? New Yahoo!
