How can fighter jets fly upside-down in regards to the fuel intake

1.33K viewsEngineeringOther

Me and my brother are at a loss, we understand the basics of how the upside down thing works, but how does the engine get fuel when the tank is turned around, is it a vacoom and how would that work or is the intake from the tank in the back of the it, so the fuel is forced into the engine? Thanks.

Fuel pumps will maintain flow into the engine at least in the short term, but prolonged flight upside down can cause problems on some aircraft if the pumps aren’t capable of drawing fuel from the tanks when they’re inverted.
