Abstract: A fuel storage system is disclosed having a fuel tank configured to store a liquid fuel; a controllable pressure source for altering the pressure in an ullage space of the fuel tank; and a controller. The controller is configured to determine a target pressure for the ullage space at a given time based on information relating to a temperature of fuel inside the fuel tank at the given time; and to control the pressure source such as to cause the pressure in the ullage space to be substantially equal to the target pressure.

Abstract: A fuel tank inerting module, a fuel tank inerting system for an aircraft, and a method of providing fuel tank inerting systems for aircraft are disclosed. The module includes an inlet for ullage gas from a fuel tank, a catalyst, an outlet for the ODA, sensors, filters and valves. The module is sized and shaped to fit in a range of positions near to fuel tanks in various aircraft. The inerting system includes one or more modules connected to the fuel tanks and a controller to control passage of ullage and ODA between the fuel tanks and the modules. The method includes providing an inert gas generation module compatible with any suitable aircraft, positioning one or more modules in an aircraft at locations near to a fuel tank to be inerted.
