• Final Report - Studies of Improved Saturn V Vehicles and Intermediate Payload Vehicles (P-115)

Hey, what's the plan for conveying the J-mission upgraded Saturn's capabilities? On talk:Saturn V? Ping me with a msg on my talk page, to let me know you replied. Boundarylayer (talk) 01:27, 31 August 2015 (UTC)Reply

Thanks for the reply!

I personally prefer your option 2) have actual data about Saturn V LEO lift/payload capabilities". Perhaps I am simplifying this a bit too much, but once armed with that statistic for Apollo 15-17 for a eastward lift-off with as near to zero inclination as possible(so as you know, to get the maximum boost from the earth's angular momentum, which is typically done and not "cheating" from launch sites near the equator.)

Will we not then have, the real-world figure? I know the S-IVB stage is considered part of the mass lifted to LEO, but that's no problem, to me anyway.

Which has me wondering, is there some sort of Fédération Aéronautique Internationale methodology to determining a launch vehicle's LEO lift capability, for comparison purposes with other vehicles? Do they define exactly what orbital altitude is required?

I'll look into that side of things. Hmm, doesn't appear to exist unfortunately.

As a point of comparison to the SLS, on pg 4, the Ares V conceptual vehicle, in ARES V: SHIFTING THE PAYLOAD DESIGN PARADIGM It was estimated to eventually be capable of a payload+ plus or minus ~ 143 tons to a 200 km altitude with 20 degrees of inclination launched from what appears to be pad 39B. It also includes a graph of lift capability for inclination orbits between 20 to 51.6 degrees the latter being the shoddy compromise (ISS inclination).

+[no mention of total payload & stage, just "payload" unfortunately]
