What mechanism is commonly used to move fuel overboard in jettison systems?

In jettison systems designed for aircraft, boost pumps are the mechanism commonly used to move fuel overboard. These pumps are specifically engineered to assist in the rapid transfer of fuel, especially during emergency situations when weight reduction is necessary, such as in the event of an aborted landing or to comply with structural limits.

Boost pumps operate by creating a positive flow of fuel from the fuel tanks to the designated jettison points. They are effective because they can generate the necessary pressure to move fuel at the required rate, ensuring that fuel is ejected efficiently and safely from the aircraft's system.

The design and operation of boost pumps allow for controlled and quick fuel jettisoning, which is vital for ensuring safety during critical phases of flight. Their capability to handle different fuel viscosities and pressures enhances their reliability as a choice for managing fuel flow in such systems.
