Embodiment Construction

[0082] figure 1 An exemplary VTOL multirotor aircraft 1 with an aircraft airframe 2 is shown. The airframe 2 defines a supporting structure, hereinafter also referred to as the "fuselage" of the multirotor aircraft 1 of the VTOL.

[0083] The fuselage 2 has an extension in the longitudinal direction, an extension in the transverse direction ( figure 2 , image 3 , Figure 5 , Figure 6 , Figure 9 and Figure 10 In 1b) and the extension in the vertical direction, the longitudinal direction is exemplarily represented by the arrow 1a, and the arrow 1a also exemplarily indicates the forward flight direction of the multi-rotor aircraft 1 of VTOL, the vertical direction is exemplarily represented by Arrow 1c indicates that arrow 1c also indicates, by way of example, the vertical take-off direction. Fuselage 2 may be connected to any suitable landing gear, such as skid or wheel landing gear.

[0084] Preferably, the fuselage 2 defines an internal volume 2a suitable at least...
