Parachutes destroyed launching (It's only the icon warning you not to deploy, the Moderators)

[tomtal]

After updating the latest version all my launches have the same issue. My parachutes burn out during launch and become useless. Now I have a dozen souls on station and in orbit with no way to get home! Any ideas?

[Claw]

Sounds like you might be heading to orbit too fast. Are they exploding? Or are you getting a message that says something like "Destroyed due to Heat and Areo forces"?

Explosions would be caused by flying too fast in the atmosphere and overheating the part.

Getting the aero message means that the part is getting activated while flying too fast (the parachute rips off when trrying to deploy).

Also, in 1.0.5, there is a red marker that appears on the background of the stage icon (the square of the icon turns red, but not the outline of the parachute). This marker only means it is unsafe to deploy the chute, but as long as you don't deploy when red, the parachute is fine. If the parachute part of the icon is red, then the chute is cut. I mention this, because it's tripped up a couple people.

I thought that as well, so I crawled to orbit, to no avail. The chutes turn red as well as the staging icon and the chute regardless of where I place them at about 5000m at under 400ms. I tried launching saved craft that worked well before but now nothing will get a chute to orbit. When I get there the staging Icon looks normal again but when I attempt to deploy chutes they turn red and fail to open. Very frustrating!

I can confirm that.

After upgrading to 1.0.5 (1028) all my previously built spaceships cannot be launched anymore because the parachutes get destroyed.

I launched a rocket very very slowly and had the parachutes destroyed at a speed of below 250 m/s between 8000 and 10000m. I stayed around 200 m/s below 5000m. The chute icon in the staging area turned yellow and red.

If the icon is only turning red and not the part I think it's an indicator that you are above the safe speed to deploy. Or is that not what you are refering too? That indicator helps tremndously as you do not have to right click the part to be certain.

Are you saying it turned yellow and red after deploying or before?

Edit: NVM, i'm stupid. 8)

 

Did you regain speed? I think I've deployed early and dropped engine speed and destroyed them that way. Gravity builds up speed quickly without something stopping it. Although that may be obvious. The parachutes obviously can't maintain full drag at those altitudes as they can't deploy. Makes me wonder what they should be able to handle at full altitude realistically with so little atmosphere. I wonder how accurate the game is.

tomtal, alfora, relax all your craft are fine, the red icon is only telling you that it is unsafe to deploy the parachute at that speed.

Parachutes can only be destroyed in the undeployed state by crashing them into things or by going so fast the whole part overheats and explodes, if you are doing that your rocket will explode from overheating shorty afterwards.

Arugela, it is incredibly hard to build high altitude high speed parachutes in real life, they do not simply work due to lower pressure, the speed is too great.

The KSP parachutes are not for supersonic use, the drag chutes can cope with a little more but realistically they should be torn to shreds at high speeds.

And they are.

Arugela, sal_vager: We are not talking about deploying a parachute at re-entry but about the chute being destroyed while launching the rocket!

This is neither re-entry nor hypersonic speeds and not about deploying the parachute. It is simply sitting at the top of my rocket in order to be used much much later in the mission.

[alfora]

I just re-tested this with a very simple rocket. The chute icon turns red a high speeds but returns to normal when you are in the upper atmosphere.

Did this behaviour change in 1.0.5?

IMHO this is very misleading. Deploying the parachute in the upper atmosphere or in orbit is also not "safe". I'd rather have red lights when something is broken and not when something is unsafe to do.

Go back and read what sal_vager said again.

What you are seeing, is an indicator on the staging ba to tell you it is not safe to deploy chutes.

Here let me show you:

Here we see Stage 0 is showing that the chute is not safe to deploy (which I suspect is what you are seeing)

Here we see a deployed chute destroyed. Notice the difference in icons.

Yep, I just re-tested it but I really was confused. If I remember correctly the red icon indicated that the chute was destroyed in previous versions, wasn't it?

Besides, I also find it very confusing that being in the upper atmosphere or in orbit is considered as "safe to deploy".

Well yeah, safe for the parachute. That's no guarantee that it'll do anything useful though.

The atmosphere is thinner higher up, so the chute won't be ripped off. That doesn't mean you should deploy it. It was the same before, just less visible as you had to right click to see it

My bad.

It is even written in the release notes of 1.0.5 which I always read and study thoroughly (*cough*).

I simply was confused by the new red icon during launch that looks very similar to the icon that is visible when the chute is destroyed. All my flights are always so perfect (*cough* *cough*) that I never had a destroyed chute before...
