Input: Bedford firm Hybrid Air Vehicles (HAV), which is behind the combined plane and airship, says its wants to reduce its carbon footprint and create "zero-carbon aviation". The money from the UK Aerospace Research and Technology Programme, may not "be enough" an aviation consultant said. The work could take several years. The project, named E-HAV1, will develop a prototype 500kW electric propulsor to replace its fuel-burning forward engines, HAV said. It would take "several years" to develop the new engine and bring it to market, an HAV spokeswoman said. The prototype £32m Airlander 10 was formally retired after its collapse in 2017, following six successful test flights. Work is now under way to develop the next Airlander 10 and full production due to start soon, HAV confirmed. This version of the craft uses a combination of buoyant lift from helium, aerodynamic lift and vectored thrust. HAV chief executive Stephen McGlennan said reducing carbon footprints was "one of the biggest challenges facing aviation". "This project will move us closer to our goal of zero-carbon aviation," he said. Tony Dixon, an aviation consultant said: "We will have to see if they can prove [the new technology] can work, as its engines are already low in emissions, but the lower the better. "I am not sure £1m will be enough." HAV, Collins Aerospace and the University of Nottingham have been jointly awarded the grant.
