Visualising Sustainable Aviation Research for FIA26
As part of the FIA26 communication and dissemination activities, MINIMAL designed a series of eight posters highlighting the project’s research on climate-optimised aircraft propulsion. The posters present complex technical topics in a clear, accessible and visually engaging format.
The poster series includes:
Minimum Environmental Impact Ultra-Efficient Cores for Aircraft Propulsion
Introducing the MINIMAL project's vision for climate-optimised composite cycle engines, hydrogen combustion technologies and ultra-efficient propulsion systems for future aircraft. (Chalmers University of Technology)
Ultra-Low Emission Innovations for Mid-Century Aircraft Engines
Showcasing breakthrough propulsion technologies developed in the ULTIMATE project, the predecessor of MINIMAL. The poster highlights innovations such as constant-volume combustion, intercooling, recuperation, secondary combustion and bottoming cycles, which laid the foundation for the climate-optimised composite cycle engine concepts now being advanced within MINIMAL. (Chalmers University of Technology)
From Low-TRL Research to Climate-Neutral Aviation –
Presenting the ClimAvTech technology roadmap and the role of European collaboration in accelerating sustainable aviation innovation. (PNO Innovation)
Ultra-Low Emission Innovations for Mid-Century Aircraft Engines
Exploring breakthrough propulsion technologies for next-generation sustainable aviation. (Chalmers University of Technology)
Assessment of the Free Double Piston Composite Cycle Engine
Evaluating the performance, emissions and technology readiness of the Free Double Piston Composite Cycle Engine (CCE). The poster presents its potential to improve thermal efficiency and reduce fuel burn, while addressing key challenges such as NOx mitigation, component integration and the roadmap towards future deployment. (Bauhaus Luftfahrt)
Climate-Optimised Engine Design
Addressing both CO₂ and non-CO₂ effects in the design of future aircraft engines. (TU Delft)
FDP-CCE Thermal Management System Approach
Developing thermal management strategies for free double-piston composite cycle engines to improve efficiency and reduce emissions. (Aristotle University of Thessaloniki)
Composite Cycle Engines with Opposed Free Piston Cores to Minimise Climate Impact
Investigating advanced hydrogen-powered composite cycle engines with opposed free piston technology. (Cranfield University)
The poster series brings together some of the research being carried out within the MINIMAL project, highlighting new approaches to reducing aviation’s environmental impact. The posters were presented at FIA26 to share these developments with the wider aviation research community.
