Can we get things to stay in cargo bays?


Recommended Posts

I was making an Apollo style landing with two new crafts (transport and lander) in which the transport has a cargo bay to let the lander survive re-entry. Yea maybe it could have been more efficient money wise but I was able to take it in from Jool to Kerbin with 2 Kerbin aerobrakes (the first one took a lot of quick saves to get altitude just right) at 100% re-entry difficulty.

As I'm coming down this happens (the inner craft comes outside the cargo bay through the wall, a lot. It got more drastic after my picture) https://www.dropbox.com/s/qy3e0n6zo7uaof5/2015-08-06_00007.jpg?dl=0

Someone made a thread about "magical" cargo bays that I guess freeze things in place in them? That would be great, but im fine with things moving in the cargo bays, just not them coming through the walls. Also note that if you disconnect yourself from an object that is in your cargo bay and time accelerate, the object will travel outside your ship like the bay is not there.

The return took a few quick save reloads to get it down, and surprisingly it did not tear my ship apart like I was expecting; it just flailed around violently and made me annoyed and very worried. I think this maybe due to Claws stock bug fixes I have installed; they fixed my Glue Kraken issue (Claw's my hero), and maybe stopped the ship from being torn apart? Aside from that its an all stock game from Steam.

It was brought on when the ship got lower in the atmosphere, not when it was going 4.4km per second through 70-38km atmosphere range. The weight of the ship is slightly towards the rear and I bring it down from front-forward because you need a heat shield, and that made it go side to side a little, but the ship was controlling it well; until the lander in the cargo bay flings out from the inside and screws everything up. Did it ruin my $400k mission? No. Did it destroy my ship or corrupt my save? No, and I'm happy about that. Was it extremely unrealistic and an unsatisfying end to the mission? Yes, but I got 2.2k science out of it.

It would be really great and realistic to have the parts inside the cargo bays stay put and actually contain things, or better yet let Engineer Kerbals make temporary struts in space to secure objects (and not just those inside cargo bays). Please note my craft is connected inside the cargo bay via a docking port. A Sr. docking port may help it, but it would look weird and im good on that.

One last thing: is it weird that during Kerbin re-entry while coming in straight that there are not really flames on the right side of my ship? https://www.dropbox.com/s/hag781o8g7uzj6g/2015-08-06_00004.jpg?dl=0 I mean if im coming in sideways yea, but im going straight in.. I've been debating if this should have gone in the development suggestions fourm or here; I chose here. If it's not a bug and you can move threads feel free to move it there

Oh yea and once it landed and I clicked recover, the game crashed and gave me this error report. Upon starting game back up, my ship was still in the water it landed in and i was able to recover it

Well, all I do is put a strut from the other end of my payload to the bay wall, usually one single strut is enough and as it's in the bay it isn't adding to drag.

That's only good for taking cargo up though, as you can't place struts in space.

So what I do when I have an object I know I want to recover later is place docking ports on both ends, small ones are fine.

Something I need to test is using landing legs to hold the floppy end of a payload, the feet of some of the landing legs are actually separate parts, so they can press against parts of the same vessel.

Wheels are also separate parts, so a small wheel in the floor of the bay should act as a stop, preventing the payload from moving through it.

Edit:

Works with the LV05 and LV-01 if the wheels are placed on another part outside the bay then clipped inward, doesn't work if placed on the bay itself.

Yep that's a full orange tank, it's still supported even if the bay is closed and reopened.

Hey I tried this out finally but it does not seem to be working.. I placed the fixed landing gear on a "pocket I beam" that is attached to the wing outside the cargo bay, but it is not holding up the cargo..

The bottom wheels look upside down, unlike real wheels the KSP wheels only seem to work then the bottom of the wheel is on the ground, try fitting some rover wheels on a rover sideways and you'll see what I mean.

Because there's a limited spot where wheels will work the angle of the wheels when trying this becomes important.

Also make sure they aren't contacting the very edge of a part, as the collision mesh isn't always the same size or shape, in my tests with the Jumbo-64 I had to move the wheels in a bit nearer the grey ring, as if they were too close to the end of the tank it'd not collide, and not work.

So I was actually able to fix it by doing the opposit and placing the fixed gear directly on the cargo bay https://www.dropbox.com/s/0l3sg966n90bkef/2015-09-02_00007.jpg?dl=0

Having the wheel(s) more at the center and not at the edge of the Jumbo probably helped too

OK so they do their job going up, but coming down during re-entry is a different story. I brought a lander up, and brought down a slightly different lander that needed replacing. On the way down, the new lander does not listen to fixed gear stoppers https://www.dropbox.com/s/jh56n5ero85ztuc/2015-09-02_00016.jpg?dl=0

Im going to do a test run without switching out the crafts to see if its only because there is a different craft in the cargo bay

SOMEHOW I managed to still land it but it was getting extremely unstable with the lander flopping around like a wet fish.. https://www.dropbox.com/s/i9mcilf4dyml4a1/2015-09-02_00018.jpg?dl=0

Is there anyway to make things work lol

Using the same cargo on re-entry still seems to neglect the wheel stoppers for me: https://www.dropbox.com/s/i9mcilf4dyml4a1/2015-09-02_00018.jpg?dl=0

I definitely think ill try out the attachment system, but it would be nice to see that not needed in future updates. I don't really like using mods since the game is already a bit buggy

Thanks Sal!
