Cubesat Tether Deploy

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.
