Fuel Systems

Design engineers in the aerospace industry often face complex, multi-domain interactions between physical and control systems when it comes to fuel related operations.

Whether it's an analysis of fuel pressurization, re/de-fueling, fuel storage or transfer or highly complex operations as in-flight refueling, aerospace engineers can benefit from a model-based system engineering (MBSE) approach using Modelica libraries.

Analytic MBSE using Modelica libraries delivers a comprehensive multi-physics platform, reducing the need for time-consuming co-simulation. It provides the versatility to implement all types of system architectures and to reach real-time simulations. 


  • Proven methods for design and verification of fuel systems on civil and military aircrafts 
  • Analysis and verification of system behavior during various dynamic operating modes and flight conditions, including effects of large variations in acceleration, direction and altitude

  • Robust fuel systems that deliver maneuverability in critical situations

Real time 

Such solutions offer the possibility to develop complex and accurate models that can be run in real time and by using the same high-fidelity models throughout the design and validation process.

These solutions feature inline integration as well as mixed-mode integration.


The scope here is to dynamically simulate mass and energy balance, assess temperatures in relation to flash point/ lower and upper flammability limits and be able to model heat and mass transfer, and solubility.


The objective of inerting applications is to analyze the dynamic propagation of species as nitrogen and oxygen and set the inerting system to ensure admissable oxygen concentrations throughout the envelope.
