Development of the initial certification and technology roadmap for the FUTPRINT50 framework

The main goal of the research project FUTPRINT50 is the acceleration of the introduction of a hybrid-electric regional aircraft. One essential part of this project is to develop a roadmap which couples the technological development with its associated research infrastructure and regulatory aspects. This aims at maximizing the likelihood of a successful hybrid-electric 50-seat regional aircraft with a projected entry-into-service by 2035/2040. This article presents the roadmap framework and methodology worked out by FUTPRINT50. Additionally, it shows the findings of the consortium about key enabling technologies and testing infrastructures necessary to achieve the final integrated demonstrators that provide evidence for lowering the risk of adoption and for bridging mapped regulatory gaps in regard to hybrid-electric propulsion. Furthermore, links to other complementary roadmaps are highlighted. Detail is given on the status of work and follow-up actions towards its completion.
