Definitions
- the present invention relates to an aircraft, in particular a fully electric, vertical take-off and landing (VTOL) aircraft.
- VTOL vertical take-off and landing
- VTOL refers to any type of aircraft, drone or rocket that has the ability to take off and put back on essentially vertically and without a runway. This collective term is used in a broad sense below that is not only
- Fixed-wing aircraft with wings but also rotary-wing aircraft such as helicopters, gyroplanes, flight screwdrivers and hybrids such as compound helicopters or combination screwdrivers as well
- CN 203655658 U discloses a forced air cooling system for small electronic components.
- CN 204858936 U refers to a magnetic transmission system for a propeller from an axis offset from the rotor assembly.
- the invention provides an aircraft, in particular a fully electric aircraft capable of taking off and landing vertically in the above sense, according to independent claim 1.
- An advantage of this solution lies in the reduced shading of the active surface of the propeller according to the invention, which in conventional aircraft follows from the central arrangement of the engine.
- Embodiments of the invention also allow an increase in efficiency and a higher degree of integration of the propeller shell.
- the aircraft can be equipped with kinked or even optionally kinkable wings.
- a corresponding variant increases the wing area effective in horizontal flight, but without extending the footprint of the aircraft.
- the aircraft may have a quickly chargeable battery system which provides the drive energy for vertical take-off and landing as well as horizontal flight and enables the aircraft to be charged at short notice when stationary.
- ducted fans of different sizes can be used to drive the aircraft, as are known apart from aeronautical engineering, for example, from hovercraft or sump boats.
- the cylindrical housing surrounding the propeller can considerably reduce the thrust losses due to turbulence at the blade tips.
- Suitable jacketed propellers may be oriented horizontally or vertically, designed to be pivotable between two positions or out
- FIG. 1 An embodiment of the invention is shown in the drawing and is described in more detail below.
- the figure shows a schematic diagram of the invention.
- the single figure illustrates the structural features of a preferred embodiment of the aircraft according to the invention.
- an electrical machine 11, 12
- an electrical machine 11, 12
- Both their rotor (11) and stator (12) are outside the effective range (14) of the associated jacket propeller (10). This avoids shadowing and fully uses the driving force.
- a guide rail or other axial bearing (13) maintains the air gap of the electrical machine (11, 12).
