DLR-F25

The most important differences to today’s short-haul aircraft are:

1. Foldable wingtips to increase the aerodynamic efficiency and still fit into the 36m gate limit.
2. Carbon fiber reinforced polymer (CFRP) wing structure to reduce wing mass featuring advanced load allevation.
3. Advanced on-board system architecture.
4. Ultra-high bypass ratio (~15) turbofan engine.

EXACT Turbofan Baseline

The most important differences to today’s short-haul aircraft are:

1. Foldable wingtips to increase the aerodynamic efficiency.
2. Carbon fibre reinforced polymer (CFRP) wing structure to reduce wing mass.
3. All electric on-board system architecture.
4. Ultra-high bypass ratio (~15) turbofan engine.

EXACT Turbofan LH2 Hybrid

The most important differences to today’s short-haul aircraft are:

1. Mild-Hybrid-Electric-Propulsion (MHEP) architecture consisting of two gas-turbines and fuel-cells instead of a conventional gas-turbine propulsion
2. Liquid hydrogen (LH2) as main energy carrier
3. Foldable wingtips to increase the aerodynamic efficiency
4. Reduced wing mass and higher wing-spa through carbon fiber reinforced polymer (CFRP) wing structure instead of aluminum
5. All-electric on-board system architecture
6. 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%)
7. Reduced energy consumption per passenger by an increased passenger capacity

DLH25

The most important differences to today’s short-haul aircraft are:

1. Liquid Hydrogen as an energy carrier.
2. Increased wing span (45.0m) for improved aerodynamic efficiency.
3. Carbon fiber reinforced polymer (CFRP) wing structure to reduce wing mass.
4. Ultra-high bypass ratio (15) turbofan engine.

Commuter Aircraft

The most important differences to today’s short-haul aircraft are:

None, the Commuter Aircraft is an interpretation of a current aircraft.

NACOR BWB

The most important differences to today’s short-haul aircraft are listed below:

1. Novel configuration of a blended wing body instead of tube and wing.
2. Reduced engine noise compared to today’s aircraft as the aft engine is located on top of the centre body.

ZEexplore Truss-Braced-Wing Turbofan

The T25 features a strut to enable a slender, high-aspect ratio wing, yielding an improved aerodynamic efficiency without a significant increase of the wing mass; the wingtips are foldable to maintain a good compatibility with existing airport infrastructures. Furthermore, as the high aspect-ratio wing has a low internal volume, part of the fuel is stored in an integral fuselage tank.
