The problem with DLR ( and the Dutch NLR) is that they do not build airplanes, Airbus does, has a much larger budget and lots more people on their Research department. and so far none of the DLR/NLR projects /concepts has ever seen the light of day.
One thing they got right apparently is the hybrid concept . In AERO 24 last month a French company showed a 19 seat hybrid aircraft the ERA, with 150 NM range on pure electric and 600 NM range on hybrid using 2 small APU turbines to recharge the batteries using SAF ,They have already over 500 pre-orders, .mostly from islands and mountainous areas countries., Operational 2028-2029. We'll see.
