Long-time space elevator fan Maurice Franklin has created a very interesting document, the Space Elevator Analysis Spreadsheet. He explains it as follows:
The Space Elevator Analysis Spreadsheet provides you with the ability to calculate the characteristics of a Space Elevator and vary the inputs to those calculations. Thus the spreadsheet allows you to see the impact upon the mass, capacity, time to build and other important aspects of a Space Elevator when different strength of ribbon, type of deployment spacecraft, efficiency of climber power array or other critical choices are made. As provided, this spreadsheet follows closely the choices and calculations made by Dr. Bradley Edwards in his NASA Institute for Advanced Concepts proposal, though the author has attempted to validate the calculations independently of his work.
The author has three goals for this spreadsheet. First, that Space Elevator enthusiasts wishing to dig into the physics (and thus the math) behind the dynamics of a Space Elevator will find this spreadsheet a useful tool for that purpose. Second, that individuals who have critiques of the physics of a Space Elevator as laid out by Dr. Edwards, and interpreted here by the author, will have a reference against which to make a case for different calculations. Third, that anyone proposing alternative Space Elevator configurations will have be able to use this spreadsheet to work through the impacts of their configuration across the many aspects of the Space Elevator system in a consistent and complete manner.
The author looks forward to getting feedback from users of the spreadsheet, whether it be improvements in usability, alternative configuration scenarios, corrections to the physics and math, or anything else. Contact information for the author can be found on the first tab of the spreadsheet.
You can access the Spreadsheet here.
