Rolls-Royce Revs Hybrid Engine
Rolls-Royce announced on March 14 that the company had conducted successful ground tests of a hybrid system using the company’s ubiquitous M250 gas turbine. The company said that it successfully tested the hybrid version of the M250 gas turbine in a ground demonstration setting in three operating modes: series hybrid, parallel hybrid and turbo-electric.
The M250 hybrid is planned to be used as a propulsion plant with power ranging from 500 kW to 1 MW. Rolls said, “The tests are part of one of the world’s most comprehensive hybrid aerospace turbine engine development and integration programmes and pave the way for experimental flights on aircraft in 2021.” All of the major turboshaft engine producers, including General Electric, Honeywell, Pratt & Whitney and Safran, are developing hybrid propulsion systems for electric aviation.
