LH2

EXACT Turbofan LH2 Hybrid

The most important differences to today’s short-haul aircraft are: Mild-Hybrid-Electric-Propulsion (MHEP) architecture consisting of two gas-turbines and fuel-cells instead of a conventional gas-turbine propulsion Liquid hydrogen (LH2) as main energy carrier Foldable wingtips to increase the aerodynamic efficiency Reduced wing mass and higher wing-spa through carbon fiber reinforced polymer (CFRP) wing structure instead of aluminum All-electric on-board system architecture Reduced energy consumption at comparable missions through shorter design-range (from 2800 kilometres to approximately 4600 kilometres) while still covering most of the short-range market (>85%) Reduced energy consumption per passenger by an increased passenger capacity

DLH25

The most important differences to today’s short-haul aircraft are: Liquid Hydrogen as an energy carrier. Increased wing span (45.0m) for improved aerodynamic efficiency. Carbon fiber reinforced polymer (CFRP) wing structure to reduce wing mass. Ultra-high bypass ratio (15) turbofan engine.
