Made some Apollo-8 style Missions and all together 10 Aerobraking tests back at Kerbin with my new ship (Aagaeon 239), yesterday and today.
Here are the results
Orbit was every time 27.300 AP
Aerobrakings starting with 3.209m/s at 70.000m
With PE 60km resulting AP was 22.560km (-17% AP)
With PE 55km AP resulting into 22.878km (?)
With PE 48km AP resulting into 14.826km (-45% AP)
With PE 45km AP resulting into 9.995km (-63% AP)
With PE 42km AP resulting into 6.314km (-76% AP)
With PE 40km AP resulting into 4.030km (-85% AP)
With PE 38km AP resulting into 2.530km (-90% AP)
With PE 36km AP resulting into 1.385km (-95%AP)
With PE 35km AP resulting into 1.028km (-96% AP)
Was a bit surprised at the first try, that cutting 10km into Kerbins atmosphere had so little effect.
For the moment we do not have som heat effects at reentry - probably it will not be possible after such an upgrade to brake that hard.
I will do another set of tests when i have a ship that is able for Kerbol star and back, but i am not sure if i can aim that exact to be able to make such entrys interplanetary...(?)
Therefore i started to look at the atmospheric density - and made some tables:
Preassure scale (roundings) starts at
sea level: 1,2
