My rocket keeps exploding

[Elysion]

http://prntscr.com/nx3ape here is rocket i dont know whats wrong my parachutes never open and i just explode when i reenter atmosphere

[𝐀𝐥𝐩𝐡𝐚]

picture wont load for me, but try using heat sheilds.

i dont have them i just started in career mode

How do you even leave the atomsphere with your liquid engine not having any fuel, and no decouplers? Do the boosters just melt whatever is behind them when activated?



Anyway. Try to reenter at a flat-ish angle (i.e. don't burn up 90° and expect to survive reentry).

Also, add a decoupler so that only the command capsule remains (put that in a new stage, between the last booster and the chute). Strictly speaking that's not necessary, but it'll make things easier.

oh, i'd reccomend only using one engine for starting, i do it all the time.

do you only have solid fuel available right now?

Um. Many questions.

What are you doing with the staging? It looks like you've got two solid boosters, with a liquid fuel rocket (but no fuel) in between them, and no stack separators. If this works the way I expect, the first stage should function, the second stage should do nothing, the third stage should...probably blow up the first two with rocket exhaust?

After that, the question would be (A) whether you activate the parachute and (B) whether your rocket ever gets slow enough for the parachute to work before hitting the ground.

...Also, if you're burning up on reentry, I'm not sure what you expect a parachute to do.

Things that could help:
-Stack separators. Especially one to kick the rocket part off so that your capsule is reentering without all that extra weight on.
-If you add stack separators, you could also add a heat shield to the capsule. It might not be necessary, but it could help.
-Not doing a really high straight up-and-down in the first place. Burning up on reentry, under stock rules, mostly happens because you come in too steeply. In a more shallow descent, you lose speed higher up where the air is thinner so you spread out the heating over time and survive.

Yes

Yes boosters just explodes one by one. How do i arrange rockets angle ?

Steer to the side on the way up, while you have rockets running.

Ah, my eyes!

More seriously.. what is going on here? That liquid engine at the bottom has no fuel, and is staging second. The solid booster above it is staging first and presumably destroying it? There are no decouplers here, so I don't even know how you're staging.. are the solid boosters just burning up whatever is under them?

Also.. you're going straight up.. aren't you? Assuming that actually flies, and burns away the pointless parts, you've got less than 2000 delta v there at best. That's enough for a hop to space going straight up, then you'll fall straight back down and go splat.

Just turn right a bit just after liftoff (just a couple of degrees, gravity will do the rest, see https://wiki.kerbalspaceprogram.com/wiki/Gravity_turn ). Note that you'll reach a lower altitude (but it'll be easier to turn into an orbit, and you'll actually survive).

Also, while I approve of explosions and it being a very kerbal way to decouple, it probably wastes fuel.

That'll just make the rocket fall back onto the launchpad and either fall over or back to pointing straight up.
Though it does work with launch clamps.

i just started playing today :(

1. Check you staging. Looks like the bottom stage is 2. You need to get the order right.
2. No fuel for the liquid stage
3. Decouplers. You want some TD-12s between stages. Oh you don't have them yet. Then stick to one engine.

[Enorats]

He has to have the decouplers and the first small fuel tank, as I'm fairly certain that's a Swivel on the bottom. Hard to tell on my phone though, lol.

Just so you know OP.. solid boosters are like fireworks. Light them and they burn till they run out of solid fuel. You can turn them slightly, but can't lower throttle or shut them off.

Liquid engines have to be attached to fuel tanks. These are sold separately in the tank catagory, unlike solid engines which come with solid fuel built in. Liquid engines can be freely throttled and turned on/off as much as you want.. somewhat unrealistically.

Decouplers like the TD-12 go between stages, and use explosive bolts to blast apart stages for separation. Stack separators do the same thing, but don't stay connected to either stage after separation.

Reason for chutes not opening is likely Coming in too Hot!
Chutes won't open over Mach 1(ish). (+343m/s Approx) Drouges won't open above Mach 2(ish) (686m/s approx).

You need as much surface area entering atmosphere to slow down as possible. try to get your rocket sideways(Radial) if you can. however the dry weight of your rocket looks too heavy for standard chutes.

1. Add a Decoupler under your Command pod.
2. get it to stage with or before the chutes
