Abstract
An aircraft fuel tank monitoring system is disclosure including at least one first sensor for sensing a pressure of fuel within a fuel tank; at least one second sensor for sensing a pressure of an ullage space above the fuel within the fuel tank; a processor for monitoring the change in the pressure of the fuel within the fuel tank over a time period and for monitoring the change in the pressure of the ullage space within the fuel tank over the time period, and to determine a fault if the monitored pressure changes exceed normal operating conditions.
Claims20
An aircraft fuel tank monitoring system, comprising:
- at least one first sensor for sensing a pressure of fuel within a fuel tank;
- at least one second sensor for sensing a pressure of an ullage space above the fuel within the fuel tank;
- a processor for monitoring the change in the pressure of the fuel within the fuel tank over a time period and for monitoring the change in the pressure of the ullage space within the fuel tank over the time period, and to determine a fault if the monitored pressure changes exceed normal operating conditions.
An aircraft fuel tank monitoring system, comprising:
- at least one sensor for sensing a pressure of an ullage space above fuel within a first fuel tank;
- at least one sensor for sensing a pressure of an ullage space above fuel within a second fuel tank;
- a processor for monitoring the change in the pressure of the ullage spaces within the respective fuel tanks over a time period,
- wherein the ullage spaces are coupled by a cross vent line, and wherein the processor is configured to determine a fault if a pressure difference between the ullage spaces of the respective fuel tanks exceeds a threshold.
A method of monitoring an aircraft fuel tank, comprising:
- sensing a pressure of fuel within a fuel tank;
- sensing a pressure of an ullage space above the fuel within the fuel tank;
- monitoring the change in the pressure of the fuel within the fuel tank over a time period and monitoring the change in the pressure of the ullage space within the fuel tank over the time period, and
- determining a fault if the monitored pressure changes exceed normal operating conditions.
