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

1.34K 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.

The fuel intake is via a flexible tube inside the tank that has a weight at its intake end. The weight naturally causes the intake end of the tube to be wherever the bottom of the tank is at that time, based on orientation or aerobatic g forces
