Challenge: maximum aerodynamic deceleration on reentry

Recommended Posts

I got 857.4G upon decelerating from over 15km/s to 300m/s in about 3 seconds. I admit I did not use only stock parts, but the only mods I used were Aerospike engine, Solar Collector and Radial-mount Parachute (total of 4 chutes for the deceleration).

I can only assume the ridiculous G was from the deceleration rather than the 300m/s impact with the water a moment later.

Also, here\'s a screenie:

How about this video I made with non-stock parts, and the old atmosphere model showing rockets getting torn apart by re-entry forces:

I get 130,000 g\'s or thereabouts on the last attempt.

Well, my try at non-stock parts got around 106,000,000G 8)

Yes, 800+G is about what is expected at an 15Km/s re-entry, did that one at a first try with non-stock parts to see how many Gs I could do with twice as much V as I had before... With the solar collector, you could go as far and as fast as you want, especially now with time compression
