Electrified Aircraft

While the jet engine by itself has been a key source for performance improvements on recent generations of aircraft, the bulk of the remaining improvement potential lies in developing hybrid and electric propulsion concepts. Hybrid electric and fully electric concepts employ electric power sub-systems for the generation of thrust, which was previously provided by gas turbines exclusively.

Thermal Management

Thermal management is a critical performance and capability application that needs to be evaluated at a full aircraft level. Thermal loads have and continue to grow due to the electrification of sub-systems (“More Electric Aircraft”), high performance actuation systems, changes inside the propulsion system, and new payloads.

Jet Propulsion and Secondary Power

The jet engine, the key source for power on-board aircraft is a key enabler for performance improvements on recent generations of aircraft. While the propulsion system continues to offer substantial improvement potential to the industry, the underlying physics are closely coupled and difficult to master.

Fuel System Analyses

Design engineers in the aerospace industry are often faced with the challenge of improving fuel system operations. The analysis of fuel pressurization, fueling/refueling, fuel storage and transfer, or in-flight refueling, are highly complex operations and the development and refinement of such systems is essential for creating robust fuel systems.

Embedded Controls Development

Virtual development of controls requires dependable physical models, tools to support development, and highly automated testing and traceability to document and connect all artifacts of the development process.

When these controls are safety-critical, involving regulations like DO178-C they require a traceable, auditable and fully documented process. Modelon delivers the key cornerstones for this process:

  • Modelica for dependable models
  • FMI tools for process automation
  • Silver for virtualizing the development process
  • TestWeaver for test automation.
