Abstract
An aircraft fuel tank ullage safety system ( ) that is designed to maintain the fuel tank ullage ( ) of an aircraft fuel tank ( ) filled with nitrogen. The nitrogen prevents the fuel tank ullage ( ) from becoming filled with flammable fuel fumes which can cause an explosion. The system ( ) consists of at least one flexible, resilient, air-enclosing container ( ) having a container ullage ( ) that is dimensioned to substantially occupy the space of the fuel tank ullage ( ), a differential pressure sensor ( ) that determines the internal pressure of the aircraft's fuel tank ( ) and a microcontroller ( ) that controls and maintains the volume of the air-enclosing container ( ) as determined by the differential pressure sensor ( ).
