Launcher calculator

[UpForce]

An open source, online launcher calculator provided by a small rocket space launch startup, Launcher. Provides an "approximation" of performance for conventional rockets but seemingly a pretty comprehensive at that. The author is Igor Nikishchenko who previously worked at the Yutzhnoye Liquid Propulsion Department, Ukraine, as a Deputy Chief Designer. Comes with good documentation also.

It shows 318,000lbs to LEO for Saturn V. That's quite a bit more than I've seen quoted anywhere else. All that I looked at looked pretty high.

A lot more, should be something like, 250 000 pounds ?
