 * internal dimensions minus posts and wall thickness
 *  1U  = 100 × 100 ×  99.50 mm, 1.33 kg mass
 * 1.5U = 100 x 100 x 156.25 mm, 2.00 kg mass
 *  2U  = 100 x 100 x 213.00 mm, 2.66 kg mass
 *  3U  = 100 x 100 x 326.50 mm, 4.00 kg mass

 * corner posts are 8.5 x 8.5 mm, and extend 7 mm above and below ends.  Assume 1 mm walls.  The largest rectangular cavity within a 2U is 83x x 98y x 211z . 

Can we roll a 160 mm thinsat to fit a 2U ?  Better to assume stiff.   

Assume double thickess thinsats - 0.04 g/cm², or 2 g/cm² per 50 thinsats.  Assume thinsats, plus center pivot, are 0.4 mm thick.  50 thinsats are 20 mm thick.   We could make a stack of thinsats 116 mm on one side - a bit more with curvature - and fit:

Assume 50 thinsats are spaced 1 meter apart on the kevlar cable, and it must support 10 gees during deployment.  Assume 500 KYuri design strength.  100 m/s² x 50 m x M(kg) is the force, divided by 500 KYuri, is the scaling factor of thinsat to kevlar: 0.01.  Trivial!

Instead, assume we are launching from a tether on a spinning rocket body.
