R-R pursuing EVTOL concept
At July’s Farnborough International Airshow Rolls-royce unveiled a concept electric vertical take-off and landing (EVTOL) vehicle that it says could be adapted for personal and public transport, logistics and military applications. It is based on existing or underdevelopment technologies and could fly by the early 2020s.
The initial concept vehicle would use gas turbine technology to generate electricity to power six electric 'propulsors'. It would also have a battery for energy storage. In this hybrid configuration it could carry four/five passengers at speeds up to 250mph over a 500-mile range, R-R predicts, and its battery would automatically be recharged by the gas turbine. Its wings would rotate through 90° for VTOL operation. Once it reached cruise altitude the wingmounted propellers would be stowed to reduce drag and cabin noise, with the two rear propeller/rotors then providing thrust.
