US Patent 10252796 Rotor-blown wing with passively tilting fuselage

An aircraft includes a wing where a first rotor and a second rotor are coupled to the wing at a fixed position relative to the wing. The aircraft also includes a fuselage and a bearing. The bearing mechanically couples the wing and the fuselage and permits the wing and the fuselage to rotate with respect to each other about an axis of rotation. The bearing permits the fuselage to rotate under the influence of gravity to be in a same orientation relative to ground when the wing is in a first orientation relative to the ground as well as a second orientation relative to the ground.
