Hybrid-Electric Concepts:
- Parallel hybrid electric powerplant, with next generation thermal engines and small electric engine employed to maximize thermal engine efficiency (take off & idle phases)
- Propulsion electrification integrated with more electric aircraft systems
- Small, cost-efficient battery
Fuel Cell Concepts:
- Fuel cell propulsion system, leading to a zero carbon, NOx and soot emissions, more efficient than small gas turbines, but heavier, and requires complex thermal management
- Advanced propulsion installation with optimization strategies for fuel cell thermal management, reducing weight and drag
