Is this normal?

[TheScareCake!]

Was flying a jet while listening for classical music, but got bored. I turned around, and when i was decending from the sky, i was about to cut the throttle and land.

Noticed this:

Is this.. nominal? A bug?

Well, the thrust of -0.3kN certainly doesn't look normal. Do you have any mods installed? Do you have an output_log.txt , craft file and/or a savegame? Was this taken before you reduced throttle at all?

[Starwhip]

Um... no?

I've never seen that before.

Genius! You have created a vacuum brake!!!! You can use it to slow down when you don't have air brakes.

My ksp is... slighty modded. I mean, it does have near, deadly reentry, procedural fearings, some enviromental mods like planet shine, chatter.. No mods that would change the jet engine. And this craft is all stock, its a simple jet with f-22 alike wings and two jet engines as seen in the photo. Strange thing is that i tried to cut the throttle, then i noticed this. Then, i tried to move it to 50%, then 100%, it didnt changed.

Sounds like a glitch/bug then.

FYI, NEAR changes Jet engines, but it shouldn't do that.

Can you show a better picture of the plane?

[TheScareCake!]

Its very simple.

Its very simple.

I should have been clearer, can I see the back of the plane? I noticed the wheel in the first image might be clipping and I'm wondering if this lack of thrust is due to it considering them blocking the thrust output. I'm having trouble seeing it because the image is so dark.

Well, this is strange and none of my own jets do that.

However, 0.3 kN is 300 N. You have 2 engines, so that is 600 N of reverse thrust. That's 60 Kg. Not enough to lift a kerbal.

From the engineering point of view it will not do anything, so you can just go on and ignore it.

The negative number is probably just a floating point/average issue. The bigger issue is that he is at half throttle with plenty of air and fuel and has no thrust.

I cant leave this like that. Might investigate this further, i want to find a way to increase the negative thrust. Who knows?

Have you tried turning it on and off again? xD I would recommend seeing if you get the same issues with a different craft with the SAME jets. If that craft has the same issues, than I would go about uninstalling mods and testing after an uninstall of each mod. If having no mods still does not fix it, I would recommend reinstalling KSP entirely.

Hope this helps,
