Thinsat Area


Triangular Thinsat area

Assume rounded corners for circular electrochromic thrusters.

Start with two dimensions - thruster diameter D , and thruster-to-thruster spacing S defining the sides of an equilateral triangle within the body of the thinsat. We can decompose the thinsat into three kinds of area:

thruster to thruster spacing S

17.32
