Airbus Defence and Space selected Catalyst engine to power Eurodrone. It is a great success for our program. A team of some 400 European engineers, including over 200 Polish engineers, spent the past decade developing this groundbreaking turboprop aircraft engine. Catalyst was designed and developed by engineers Engineering Design Center in Poland, Avio Aero in Italy, Poland and the Czech Republic, with the innovative design support of the Advanced Technology Center in Germany. They combined technology from large commercial jet engines with digital engine controls in a way that opens new design options for plane-makers. Their engine also aims to deliver fuel savings and cut CO2 emissions by up to 20% compared with engines currently on the market, and it is already running on sustainable aviation fuel (SAF), sometimes referred to as biofuel, and even powers hybrid aircraft.
