8 A vertical take-off and landing multirotor aircraft with at least eight thrust producing units

摘要

The present invention relates to a vertical take-off and landing multi-rotor aircraft (1) with an airframe (2) and at least eight thrust producing units (4a, 4b, 4c, 4d, 5a, 5b, 5c, 5d). An objective of the present invention is to provide a vertical take-off and landing multi-rotor aircraft (1), which provides at least improved efficiency both in hover and cruise operation. Each of the at least eight thrust producing units (4a, 4b, 4c, 4d, 5a, 5b, 5c, 5d) is provided to produce thrust in an associated predetermined thrust direction. At least four thrust producing units (4a, 4b, 4c, 4d) among the at least eight thrust producing units (4a, 4b, 4c, 4d, 5a, 5b, 5c, 5d) form a first sub-assembly of thrust producing units. At least four other thrust producing units (5a, 5b, 5c, 5d) among the at least eight thrust producing units (4a, 4b, 4c, 4d, 5a, 5b, 5c, 5d) form a second sub-assembly (5) of thrust producing units. The first sub-assembly (4) of thrust producing units is operable independent of the second sub-assembly (5) of thrust producing units.
