Keeping in mind the need to meet environmental goals while still providing lightweight, aerodynamic, and strong parts, the doors demonstrator for the RACER was recently finalized by LKR Leichtmetallkompetenzzentrum Ranshofen GmbH and Composite Impulse GmbH & Co., including pilot and co-pilot cockpit doors, sideward sliding cabin doors, sideward luggage doors, and backward avionic doors. The doors were created using carbon fiber reinforced polymer (CFRP) manufacturing technologies to meet the mechanical and performance requirements including withstanding high air pressure loads resulting from the cruise speed. 

The RACER demonstrator will be assembled and flight tested in 2022.
