Rolls-Royce has begun ground testing a hybrid propulsion system using its M250 gas turbine engine for helicopters that the company says will clear the way for experimental flights on aircraft within two years.
Rolls-Royce Completes First Ground Test of Hybrid-Electric Propulsion System
Key Takeaways:
- Rolls-Royce has initiated ground testing for a hybrid-electric propulsion system, utilizing its M250 gas turbine engine, with the aim of conducting experimental flights on aircraft within two years.
- The system successfully demonstrated three operating modes—series hybrid, parallel hybrid, and turbo-electric—and is designed to provide 500 kW to 1 MW of power for various transport platforms, including eVTOLs and hybrid helicopters.
- This hybrid propulsion technology integrates the M250 engine with a battery system, generators, and advanced power management, promising efficiency gains, reduced noise, and lower emissions for a new class of cleaner air transport.
