#20 – Airbus engineer Oliver Family on the E-Fan X demonstrator

Oliver Family is the Overall Aircraft Design Leader of the Airbus E-Fan X demonstrator. The E-Fan X is a hybrid-electric technology demonstrator being developed by Airbus, Rolls-Royce and Siemens based on a British Aerospace 146 regional airliner. The driver behind the E-Fan X demonstrator is that current aircraft designs have converged to a near-optimum, and with existing technologies, it is difficult to meet the stringent sustainability goals in terms of CO2/NOX emissions and reductions in noise. New technologies, such as electrification, are therefore required to achieve these goals.

As we have seen on other episodes of the podcast, electrification of aircraft is currently a hot topic with new start-up companies promising to disrupt and revolutionise the regional aircraft market. In this environment, one may assume that incumbents like Airbus are too slow to react to a changing technology landscape. As you will hear in this episode, nothing could be further from the truth. The E-Fan X project is structured as a separate entity within Airbus with the explicit mission of challenging Airbus’ legacy business. As you will hear, the consequences of integrating an electric propulsion system on a regional aircraft run much deeper than mere calculations about battery power density and battery longevity. In fact, it's the secondary effects that we rarely think, hear and read about, such as thermal management of batteries; the interaction between pilots and new control systems; and the challenges of new certification protocols, that are especially challenging. So in this episode, Oliver and I discuss:

• what exactly the E-Fan X demonstrator aims to achieve
• the main technical and economic challenges of electric aircraft
• and how electrification widens the design envelope for engineers
