First, technology has advanced – particulary in flight controls and avionics as well as materials, meaning that structures can be made lighter. The second huge driver is the environmental challenge that aviation faces today. Cabin space reaches new heights Airbus believes that a BWB would open up exciting new possibilities for cabin interiors with increased space and comfort. Windows are thus likely to be virtual via large HD display screens. Airbus 4 AEROSPACE Starting small Airbus declines to give an exact seat count for MAVERIC but notes that its footprint at airport gates would be more compact than existing single-aisle airliners. Jean-Brice Dumont, Airbus EVP Engineering, also notes that the MAVERIC BWB is scalable in size. Secret flight tests Powered by two model jet engines, a 3.2m wingspan sub-scale demonstrator has already been flight tested in 2019 at an undisclosed location in central France. Phase 1 of the testing focused on flight controls and aerodynamics, with further tests to expand to cover industrial and operational aspects, such as maintenance, evacuation, production and airport compatibility. W AIR TRANSPORT Airbus unveils MAVERIC Revealed by Airbus at the Singapore Air Show was MAVERIC (Model Aircraft for Validation and Experimentation of Robust Innovative Controls) – subscale demonstrator for an ultra- green blended-wing body (BWB) airliner that could cut fuel burn by up to 20% compared to existing single-aisle aircraft. MAVERIC's voluminous interior, meanwhile, would open up new possibilities
