The call aims to facilitate the introduction of new aerial propulsion and energy integrated systems technologies by reducing evaluation time and cost, develop the EU's autonomous industrial sector, enhance cross-border collaboration, contribute to EU technological sovereignty and strategic autonomy, improve EU air power, and guarantee EU aerial superiority.

The specific objective is to develop a suite of advanced technologies for aircraft fighter propulsion, power, and thermal management systems, considering: understanding the potential of new aircraft configurations with advanced propulsion technologies, developing innovative solutions for propulsion systems and interconnected components, and increasing energy efficiency and effectiveness.

The scope of the proposals should include: providing a validated suite of advanced technologies for propulsion and energy systems within a SoS configuration, performing studies to explore integration challenges in different platform sizes with a focus on Unmanned Collaborative Combat Aircraft (UCCA), improving energy and thermal efficiency, and potentially addressing the joint development and evaluation of technologies on a test vehicle.

Eligible activities include studies (mandatory), design (mandatory), system prototyping (mandatory), testing (mandatory), and activities that increase interoperability and resilience (optional), qualification (optional), certification (optional), and development of technologies increasing efficiency across the life cycle of defence products and technologies (optional). Activities that aim to create, underpin and improve knowledge, products and technologies, including disruptive technologies, which can achieve significant effects in the area of defence (generating knowledge) are not eligible.

Mandatory activities include:

Studies: System studies to explore the integration effectiveness of power and propulsion technologies into airborne platforms, focusing on UCCA. These studies must cover platform requirements trade-offs, propulsion and energy systems sizing, engine integration, and improved electronic engine control and monitoring systems.

Design: Maturation of technologies and knowledge towards higher Technology Readiness Levels (TRL), including design of simulation tools, test means, high-temperature lightweight materials, thermal management systems, electrical systems, advanced cooling and manufacturing technologies, combustion technologies, and advanced engine architectures.

System prototyping: Building a modular prototype/system test bed, creating samples of new materials, and prototyping specific components.

Testing: Using test beds to evaluate energy efficiency, environmental impact, new materials, component prototypes, and new fuel types.

Additional tasks include increasing efficiency through low-cost lifecycle cost technologies, integrated lifecycle services, integration of electrical motor/generator on engine spool(s), and variable flow engines.

Proposals must substantiate synergies and complementarity with foreseen, ongoing or completed activities in the field of highly efficient propulsion and energy systems for next generation air combat and unmanned collaborative combat aircraft systems notably those described in the call topic EDF-2021-ENERENV-D-PES on Alternative propulsion and energy systems for next generation air combat systems.

The proposed products and technologies should meet functional requirements such as: flexible propulsion system design, integrated power and propulsion solutions, trade-offs of alternative solutions, analysis of potential gains and risks, technologies to minimize lifecycle cost, sustainability, efficient energy management systems, and improved engine systems.

The call is a single-stage submission process. The opening date is 18 February 2025, and the deadline is 16 October 2025, at 17:00:00 Brussels time.
