Airbus Helicopters starts flight tests with engine back-up system
Source: Airbus Paving the way for a future hybridised propulsion system for helicopters Airbus Helicopters, in partnership with the French Civil Aviation Authority DGAC, has started flight testing an engine back-up system (EBS) onboard its Flightlab. The project opens the way to a future hybridised propulsion system for light helicopters while delivering concrete flight safety improvements in the short term. The campaign’s main target is to enhance flight safety of single engine operations by providing emergency electrical power in case of a turbine failure. To conduct these tests the Flightlab was equipped with a 100 Kw electric motor connected to the main gearbox, which can provide electrical power for 30 seconds in the event of engine failure. By giving the pilot [...]
