Inflatable heatshield, attacthing to

[Majorjim!]

HI all,

 I just watched a 1.1 teaser video and it looks like the inflatable heatshield is conical when stowed. This makes me thing you will not be able to attach anything to the top of it..  It would be a major creative limitation if true as no real or proposed spacecraft have the heatshield as the top of the rocket or payload when launched.

Has anyone heard anything on this? Perhaps @RoverDude can enlighten us.

You can attach things to the pointy end of it just fine - that was demonstrated during the various live streams; it gets a shroud just like engines. Unfortunately it looks like it can't be deflated once inflated though .

OOH ok thanks for letting me know man. I didn't see that in the part I watched.

I think it was near the end of MatoroIgnika's stream on KSPTV on saturday. I'll see if I can find it.

(heatshield stuff appears a couple minutes after that)

Thanks I will have a watch.

Yup, it's got a two-way payload adapter thing going on.  Pointy side goes down, upper side sits whatever you're defending from the rigours.  DIgitalPsychosis made use of one in an accidental 50g Jool aerocapture.  Rather looked like the drag was high enough to enable a Jool landing, of sorts, or at least a gentle drift down to the heat killzone they installed to stop Danny killing the system by flying radio towers into Jool.

It seems this part is ultra draggy and even chutes can't shake you loose. I'm wondering if it's usage for a vertical Eve reentry (as it's so efficient and robust)

Roverdude commented on another thread (1.1 hypetrain maybe?) that it comes into it's own on 2.5m - 3m parts which are heavier. The drag seems high on 1.25 parts because it isn't really designed for something that light.

Mmm don't know why peeps were thinking that a balloon shaped like a dinner plate should fall faster than a rover 1/10th the balloons size and 10 times its mass. Hello, physics. These peeps must have less than an hour in KSP game time I guess. 

 

Oops sorry Warzous didn't mean to quote you. And don't know how to remove a quote.  You may be on to something.

Yes, I know that the rover was very small compared to the shield. But even with a much bigger vehicle, you may have more issues to get rid of it.

On the other hand, I was testing rover reentry skycranes / heatshield. Even a regular 3.75m heatshild is not that easy to shake it loose.

FYI, if you mouse-over the quote, a little four-way-arrow box appears at the top left corner.  Click on that, then hit "delete".

As far as i know the shield is not meant for re-entry but for aerobr(e)aking maneuvers. Its heat absorbing capabilities are not as good as those of the reguluar heat shields, but it provides lots of drag, even in upper atmospheres.

Since it doesn't deflate, my instinct is to attach it with a docking port or leave it on a mothership and come back to it if I wanna re-use it.
