beardedbuddha Posted July 14, 2011 Share Posted July 14, 2011 Hey Kerbanauts!I was looking for something fun to build, so I came up with the idea to build a rocket that would be able to:1) Take off and reach 5km2) Land safely3) Take off again and reach 5km4) Land safely a final timeThis only using standard components.I'm so close to having a working prototype, but I run into a weird problem. Have a look at this video I uploaded, showing what I do: Okay, so the first launch goes well, parachute down with help of liquid thrusters and land nice and safe. But watch what happens when I take off the second time. The first few seconds look like they're going great, but then all of the sudden the ship starts freaking out. Please note that I don't touch WASD at any point during the video.I've tried 5 different working configurations and ways of doing this. It happens every time.Am I not seeing something or could this be some bug?Thanks in advance! Link to comment Share on other sites More sharing options...
latszer Posted July 14, 2011 Share Posted July 14, 2011 If it is a bug, maybe it has something to do with the parachute not be undeployed correctly? It seems like the ship shouldn't go crazy like that but I would have to experiment. Link to comment Share on other sites More sharing options...
beardedbuddha Posted July 14, 2011 Author Share Posted July 14, 2011 You might be right.. I will see if I can land a ship without using parachutes at all... Link to comment Share on other sites More sharing options...
FreeLaunch Posted July 14, 2011 Share Posted July 14, 2011 I'd try removing the first stage and launching the second stage which is taking off after landing without it - if it goes nuts like it did after the second takeoff right off the pad without the srb stage, then maybe it's a balance issue taking off from a dead stop which is mitigated by the presence of the srb...ad astra,FL Link to comment Share on other sites More sharing options...
duke_luke_em Posted July 14, 2011 Share Posted July 14, 2011 Your rocket goes apeshit because the parachutes are still working. They don't disappear they just become invisible. If you launch and deploy your parachutes immediately, you will see the exact same behavior. Link to comment Share on other sites More sharing options...

beardedbuddha Posted July 14, 2011 Author Share Posted July 14, 2011 You guys are awesome. I just did a run without any parachutes (took it down by hand) and it worked like a charm!Thanks so much.. I didn't know that about parachutes! Link to comment Share on other sites More sharing options...

beardedbuddha Posted July 14, 2011 Author Share Posted July 14, 2011 I'm doing a video when I complete my challenge. I need to get up 5km on both trips.. Right now I'm only getting 3km on first launch and 5km on the second.. So I need to polish the rocket-design.. Link to comment Share on other sites More sharing options...

feldopropane Posted July 15, 2011 Share Posted July 15, 2011 i was messing around with the lift off and landing this is how my first few attempts looked likeand this is how my first succeful landling looked likebroke the engine but hey there is always room for improvement !

beardedbuddha Posted July 15, 2011 Author Share Posted July 15, 2011 Haha nice one on the 2nd landing. I'm uploading now. I did 5km, land, 5km, land... Now who's first to 10? Also.. it's possible to land on water Link to comment Share on other sites More sharing options...

beardedbuddha Posted July 15, 2011 Author Share Posted July 15, 2011 Here is the video of my succesful attemt! (might still be processing as I post this) Link to comment Share on other sites More sharing options...
feldopropane Posted July 15, 2011 Share Posted July 15, 2011 just watched it nice one good sir !could you share the ship file so i could try it ?if you want to keep it for yourself that is fine Link to comment Share on other sites More sharing options...
O Posted July 15, 2011 Share Posted July 15, 2011 Here is the video of my succesful attemt! (might still be processing as I post this)Very nice! By the way, I would think that if you keep the four liquid rockets for your second take-off (don't decouple them before taking off), you could reach much higher than 5km Link to comment Share on other sites More sharing options...

By the way, I would think that if you keep the four liquid rockets for your second take-off (don't decouple them before taking off), you could reach much higher than 5km if you look closely at the video you can see he damages them rendering them useless a real shame like you said he could have gone alot higer Link to comment Share on other sites More sharing options...
O Posted July 15, 2011 Share Posted July 15, 2011 ouch didn't notice. It seemed like a pretty smooth landing; I'll bet it was the horizontal movement that broke it. I've landed harder than that with functional rockets before, maybe keeping it as still has possible horizontally is the key Link to comment Share on other sites More sharing options...
BrokeDiamond Posted August 16, 2012 Share Posted August 16, 2012 You don't have to get rid of parachutes. You can still use them if you attach them to something expendable that you can jettison before taking off again. Link to comment Share on other sites More sharing options...
olex Posted August 16, 2012 Share Posted August 16, 2012 You don't even have to detach them to start again. The chutes close at <1 m/s and don't reopen when you accelerate again, I tested this. It can be seen in action on my interplanetary simulation flight, described here: http://kerbalspaceprogram.com/forum/showthread.php/17144-In-preparation-for-0-17-simulated-interplanetary-flight-and-return?p=237566&viewfull=1#post237566 - the planetary lander stage descends using parachutes, and then ascends again without dropping them.
