Hybrid <strong>Engine</strong><br />

Description<br />

• Electric driven distributed fans<br />

• Electric generator driven by a high efficient gas<br />

turbine using an advanced thermodynamic cycle<br />

• Buffering of peak power by batteries<br />

Benefits<br />

• Reduced aircraft drag if wing/fuselage wake is<br />

reduced by distributed fans<br />

• High propulsive efficiency<br />

• Optimization of gas turbine for cruise conditions<br />

• Additional degree of freedom to integrate<br />

complex gas turbine cycles<br />

• High energy content of conventional fuel<br />

Challenges<br />

• High weight<br />

• Complex system<br />

• Transmission losses<br />
