Sustainable aviation is essential to the global goal of achieving carbon-neutrality by 2050. In this course, we will start by exploring the fundamentals of aircraft propulsion systems and their environmental impacts.We will subsequently move on to explore potential solutions, with a focus on three aspects: (1) alternative fuels; (2) hydrogen technologies; and (3) electrified aircraft.Upon completion of this course, students will be equipped with the latest knowledge of technical solutions and possibilities of modern engineering to make aviation more sustainable.Moreover, the course will also encourage critical and creative thinking about the future of aviation and how you can play a role. Additionally, students will gain exposure to European sustainability efforts through visits to industry partners and workshops at leading French universities.
