British-based engine maker Rolls-Royce has announced its design of a propulsion system for a flying taxi which could, it says, be launched in the next decade.
The proposed ‘electric vertical take-off and landing’ (EVTOL) vehicle could carry four to five people. It could travel at speeds of up to 250 mph (402 km/h) for approximately 500 miles.
Speaking in the run-up to the Farnborough Airshow, Rob Watson, head of the company's electrical team, said: "We are well placed to play a leading role in the emerging world of personal air mobility and will also look to work in collaboration with a range of partners."

Rolls-Royce is not the first company to throw its hat into the ring when it comes to flying taxis. Airbus, Uber and several start-ups including one backed by Google co-founder Larry Page, Kitty Hawk, have all announced their own projects.
The initial concept for the Rolls-Royce EVTOL would use gas turbine technology to generate electricity to power six electric propulsors, designed to ensure a low noise profile. The wings would be able to rotate 90 degrees, enabling the vehicle to take off or land vertically. It could also use existing heliports and airports.
More details on the project will be disclosed at Farnborough, but Rolls-Royce did confirm it was looking for an airframe maker and a partner to work on the electrical system.
