Fuel System Library

Fuel System Library is tailored for aircraft fuel systems design with real-time capable models including gravity and geometry effects as well as mixing with air.

Fuel System Library is a Modelica model library targeting the design and verification of fuel systems on civil and military aircraft. It is designed to analyze and verify the system behavior during various dynamic operating modes and flight conditions. Aircraft are characterized by large variations in acceleration, direction and magnitude. The Fuel System Library provides simulation results accounting for these effects on fuel-air mixtures and includes full support of bidirectional flow.
Fuel System Library is a suitable tool for system and component development and enables an assessment of system performance and transient characteristics. It has
been developed internally at Modelon since a number of years together with a European airframer, and is now publically available.
The models have been designed to be efficient and numerically robust and can therefore handle large-scale complex systems. Component models include ejectors, pumps, tanks, valves, and pipes.
