In my previous post in this thread I said a beryllium heatsink would need to be like 5% for a 5km/sec reentry and 15% for full reentry, but I should have said like 25% for full reentry. These are samples 51 and 52 with "Beryllium heatsink" in the name in my simulator at http://spacetethers.com/spacetethers.html For transpiration it could be about 1/4th of this maybe. -- Vince
