Patent number: 11691722Abstract: A multirotor aircraft 10 that is adapted for vertical take-off and landing, comprising a fuselage, a thrust producing units assembly that is provided for producing thrust in operation, and a forward-swept wing that comprises a portside half wing and a starboard side half wing. Each one of the portside and starboard side half wings comprises an inboard section that is connected to the fuselage and an outboard section that forms a wing tip. The inboard sections of the portside and starboard side half wings form a central wing region. The portside and starboard side half wings are respectively connected in the region of their wing tips to an associated outboard wing pod that supports at least two non-tiltably mounted thrust producing units of the thrust producing units assembly.Type: GrantFiled: December 3, 2019Date of Patent: July 4, 2023Assignee: AIRBUS URBAN MOBILITY GMBHInventors: Axel Fink, Uwe Kiesewetter, Klaus Kicker
