A quick follow-up to Re-entry Heat Shield Alternative
Instead of looking for an alternative to heat-shield, I'd like to draw from analogous naval tactics I heard about; Back in the 1950's to 1960's, or thereabouts, in heavy weather, ships stream (or used to stream) oil over the waters for ease of passage.
Would it be possible for a re-entry capsule to use something similar to reduce it's re-entry velocity to relatively manageable levels? Say, nylon/silk threads/sheet after them - sort of like deploying a drogue, or even the chute in thin atmosphere. Pack multiple chutes, and discard each in stages as a function of air-speed, and atmosphere density.
What is the maximum re-entry velocity (I know this will vary depending upon the mass & form of the capsule - but say we're talking about Soyuz TMA-M) that would allow heat generated by passage of air to be dissipated without special shielding?
