#how to aerobrake at eve without exploding?

I have build this. At Pe 82km it does survive but not loosing enough speed for orbit. At 80km it explodes. The first thing that explodes is the fairing .. does not matter if closed or opened.

no? so what's the point of aerobrake signs at the dV maps 😄

The atmo is too dense

gentle dagger
#

can't accept that 😄

What is your atmosphere impact speed?

6100m/s

That is even for kerbin fast

now trying to go as low as possible + retrograde burn

Where is your engine?

I have two theories, but I can't be sure without having the craft file

  1. Your heat shield is too small and doesn't occlude the fairing entirely
  2. Your heat shield is big enough, but if you're coming in from a non-zero inclination, then there is a small difference in the angle between your orbital velocity and your airspeed velocity. If this is the case, then setting the navball to "surface" mode would help.

Another possibility is that your heatshield just fluxes too much heat to the other parts, in which case you can't do a whole lot, but in my experience a heat shield should be able to protect the parts behind them, even on Eve

it's a 2,5m heatshield at at 2,5m fairing, and the fairing does not go outward, just straight up. I think the main problem is, the glowing heatshield heats the fairing a lot, and heat does not get dissipated fast enough. There should be other parts which dissipate heat better

#

retrograde to surface doesnt help

both relays have 2500dV each, so I'm able to orbit them, but there are other ships on their way too
