It's not supposed to be an SSTO or have perfect aerodynamics but currently it's flipping in the air. I have tried to move CoM forward but it hasn't resolved the issue.

Plane Design [D] First SSTO/Mock SR-71

I made this SSTO and it makes it to orbit and back but it likes to flat spin during reentry if I don't babysit it like crazy but it still survives and idk what I should add to fix that or what to make next

Mods: General [M] eve redux and scatterer z fighting bug

1 Upvotes

for some reason when i use max warp on bettertimewarp's five warp and hyper warp after the 4th arrow it causes this really rapid flickering on one side of the planet, i tweaked eve settings, scatterer settings, tufx settings, nothing has worked to stop this. i will send my modlist once i figure out how to copy it.

also this happened even before i got tufx if that helps

this is also my first posting on this subreddit so if my flair is wrong tell me pls

Thinking about trying it with Minmus, like docking enough large sections together I actually get a full ring, not sure if it is possible or feasible.

I'm trying to get a satellite into a polar orbit for a contract, but my current orbit is slightly off on rotation. How do I get into the correct orientation? blue orbit is current, yellow is the one desired by the contract.

Mods: General [M] Is OPT Spaceplane mod bugged or am I just a bad builder?

The disaster video

I used large pylon as base for the wings and also angled them a bit as I read it increases lift. I think my plane has zero to none lift and after thrust is cut off it does not glide but just falls like a rock.

Space Flight [P] Earth/kerbin gravity assists?

7 Upvotes

I've seen mentions of earth gravity assists when it comes to interplanetary probes

And that confused me in regards of the how it'd work to gravity assist from your home body?

Is it referring to intercepting you home planet for an asisst after exiting it's soi? And how useful is it to do something like that?

Reentry / Landing [P] Parachute not slowing craft down during re-entry?

8 Upvotes

https://reddit.com/link/1v0ysbb/video/x5t8gmy9g8eh1/player

The parachutes on my re-entry module seem to barely slow my descent. I have a shallow re-entry angle, and I double-checked, I'm not using drogue chutes. I'd imagine the issue would be weight, only my entire craft is just a Mk3 command pod, a 2.5m heat shield, and a Mk16-XL parachute. Adding more parachutes doesn't help.

Solved [O] Weird switching and exploding problem

Thumbnail gallery
22 Upvotes

So for context I have a Mining craft on the ground mining for some fuel and I want to bring another one in, as I approach the Mining craft a weird bug quickly switches towards the landed Mining Craft and quickly hops on puts me to a loading screen goes back again to the Mining Craft and then it's either explode and gone to bits or it mysteriously is up thousands of meters up in the sky without any explanation. What should I do to fix this?

Rocket Design [D] Croosfeeding isn't working and i dont know why.

Thumbnail gallery
4 Upvotes

The lower stage of the "middle-ship" isn't receiving thr fuel from the stage above. There is a heatshield between then, is that the problem? if yes, what can i do to make it work with the shield on?
The entire thing even works, but i can only put thing in Kerbin high orbit - i want to see if i can reach Mun orbit if i have the remaining fuel.
For context: It is a 3 stage heavy orbital launcher. It's last stage is capable (i tested - even with the faling crosfeed) of being revoveres (there's a heatshild between it and the last but one stage)

Space Flight [P] Help using launch window planner tool for Moho intercept question

Thumbnail gallery
24 Upvotes

I have run into an issue using automatic transfer window calculators. For interplanetary mission, I often rely too heavily on transfer window calculator tools for quick estimates of optimal times to launch but have run into a case where I am completely stumped. Despite following all recommended planning, I am unable to achieve an intercept.

In this specific case, I am trying to send a craft to Moho, according to two separate calculators, Y3 D82 is a go for Moho. However, as we know, Moho transfer windows occur at a phase angle of about 110 degrees. As we can see in the images, on Y3 D82, Moho is very much not in the right place. This means one of two things: either both Alexmoon's and Astrogoth's tools are unreliable, or I am doing something horribly wrong. I am inclined to believe the latter. I have fiddled with maneuvers in all six directions, tried all 360 of ejection angle, and messed with mid-course burns to no avail. Moho (or my craft) is simply in the wrong place. I understand Moho is on a highly inclined orbit, but surely that cannot be the only factor preventing me from getting an intercept.

What gives? Am I relying too much on these tools? Am I using this incorrectly? Are these tools worth using or should they be abandoned in favor of just eyeballing phase angle? Am I expecting too much handholding from the community?

Example images are for a craft in an 80x100km equatorial Kerbin orbit on Y3 D82 with more than enough delta v.

Solved [O] My first plane does not take off

Thumbnail gallery
86 Upvotes

Hello guys.

I'm having some problems because my first plane does not take off. I saw some tutorials, but seems like I did almost everything right.

My center of lift is just behind my center of mass (image 1), my landing gears are aligned (image 3) and just a little bit after my center of mass (image 3). I think the problem could be my wings and the pitch, yaw and roll functions, but they are just in the way the tutorial did. Also, I think my elevon seems strange (image 4) but I don't know how to fix it.

edit: Thanks guys, I adjusted my mass and my wings. My plane takes off!

Launch / Ascent [P] Can I tell my upper stage to fly into orbit by itself, while I land the booster myself using Mechjeb 2?

11 Upvotes

Hello, I have a question hope I can explain what I mean. So I want to try myself at landing a booster stage and my idea was to have a probecore in my booster and the upper stage. I fly up to like 70km, separate the upper stage, tell it to fly into a stable orbit using mechjeb 2, switch to the booster and manually land it at the KSC.
Is that possible? Can the upper stage fly by itself without me having to focus on it? If thats the case what settings do I need to press using mechjeb for the upper stage to fly by itself into a stable orbit?
Any help appreciated! Thanks.
