Abstract
A flying apparatus is provided that comprises a airfoil (1) with a streamlined profile for generating an aerodynamic lift force vector (L) acting on the flying apparatus when being exposed to an apparent air flow. The flying apparatus also comprises at least three drive units (4, 42; 5, 51; 6, 61) being adapted to generate a resulting thrust force vector acting on the flying apparatus, the thrust force vector being alignable essentially in parallel with the aerodynamic lift force vector (L). For controlling the aerodynamic pitch of the flying apparatus, the flying apparatus comprises at least one control surface (31, 11). Furthermore, the flying apparatus has an aerodynamic neutral point (NP) that lies, along the longitudinal centre axis (10) and in the direction from the leading edge (17) to the trailing edge (18) of the airfoil (1), behind the centre of gravity (CG) of the flying apparatus.
