Spaceplane engine switch between ON and OFF ?

[Pitbull81]

Hi everyone.

Im trying to get famillar with spaceplane and Plane.

But i have a problem. Maybe someone can told me why soon as my spaceplane reach a certain angle, my engine stop then start again ?

im sure there is a simple answer and explanation, but cant find it at all.

and after 3 day of crash i start to be kinda ennoyed :mad:hahaha

Thx for your answer

It might be because your intakes are not facing the direction of movement anymore, causing a flameout due to lack of air.

First, welcome to the forums

A few more details about your problem would be helpful. What angle do you mean: angle relative to horizon or prograde ? Are you sure you don't mean altitude ? Does this happen while in atmosphere or vacuum ? What type of engine are you using ?

If you are very specific about your problem, it will be easier to solve it. Screenshots also help a lot.

But anyway, if you're using a jet engine (in air-breathing more if RAPIER) it could be because of intakes not receiving enough air due to the angle of attack of your plane (air flow is then not directly aimed at the intake and it is less efficient). Jet engines stop if they do not receive enough air; and if you have several jet engines, they may not get all the same amount of air, resulting in some engines switching on and off, and not others.

If you're too high, atmosphere gets thinner and engines receive less air, it may be linked to your issue.

Hope this helps a little, but please add screenshots, they are really helpful

I do not use jet engine but these engine : http://forum.kerbalspaceprogram.com/threads/55985

Im aware about the lack of air at high altitude. but i will take few screenshot in few minute and post them here.
