Basic performance calculator for gliders -- Michael van Jaarsveld

I am Michael van Jaarsveld, an avid model aircraft designer of gliders. I have created an XL spreadsheet that calculates the basic performance for gliders. I used the book Model Aircraft Aerodynamics Fourth edition by Martin Simons (published by Nexus special interests) as reference. It also includes some wing profile wind tunnel test results.

Download the spreadsheet here.

More on using the spreadsheets  here.
