On July 6th, the FUTPRINT50 teams from the University of Stuttgart and ADSE led the e-workshop dedicated to "Aircraft Design Specs & Mission" from our ongoing internal workshop series. With input from all consortium partners, various future propulsion technologies were investigated to test their feasibility in a hybrid-electric regional aircraft. Further to this, the vision statement was enhanced from the stakeholders’ perspective and reference missions were analyzed. Through the workshop, our FUTPRINT50 team of researchers considers that very constructive discussions emerged and brought us forward in our thinking about future conceptual designs.
