Embodiment Construction

[0048] figure 1 An illustrative rotary wing aircraft 1 is shown having a fuselage 2 connected to a landing gear 6, the fuselage 2 defining a tail boom 2a and a nacelle 2b. The rotary wing aircraft 1 comprises at least one multi-blade rotor 1a for providing lift and forward or backward thrust during operation.

[0049] At least one multi-blade rotor 1a comprises rotor blades 1b, 1c, which are mounted on rotor shaft 1e at associated rotor hub 1d. The rotor shaft 1e rotates in the rotational direction 1g about the associated rotor axis 1f in the operation of the rotorcraft 1 .

[0050] Illustratively, rotary wing aircraft 1 may include a combustion engine 150 that drives rotor shaft 1e. Combustion engine 150 may be an internal combustion engine 150 in which combustion in the combustion chamber applies direct forces to some components of the engine and from these components to rotor shaft 1e.

[0051] For example, the rotary wing aircraft 1 is realized as a helicopter comprisin...

Abstract

The present embodiments relate to a swash plate assembly (11) comprising an integrated electric motor (100). The present embodiment also relates to a multi-blade rotor (1a) for a rotary wing aircraft (1) having such a swash plate assembly (11) and to a rotary wing aircraft (1) having such a multi-blade rotor (1a). The swash plate assembly (11) may include a rotating plate (12b) mounted on the rotor shaft (1e) and rotating with the rotor shaft (1e) in operation, a fixed plate (12a) coupled to the rotating plate (12b) by a bearing (33), and an electric motor (100) generating a torque for driving the rotor shaft (1e). An electric motor (100) includes a stator (110) mounted on one of a fixed plate (12a) and a rotating plate (12b), and a rotor (120) mounted on the other of the fixed plate (12a) and the rotating plate (12b).

Description

technical field [0001] The current embodiments relate to a swash plate assembly, and more particularly, to a swash plate assembly that adjusts the total pitch and cyclic pitch of the rotor blades of a multi-blade rotor by means of an integrated electric motor. The current embodiment also relates to a multi-blade rotor for a rotary wing aircraft having such a swash plate assembly and to a rotary wing aircraft having such a multi-blade rotor. Background technique [0002] Conventional rotary wing aircraft are typically powered by internal combustion engines that rely on the combustion of high-energy fuels, often obtained from fossil fuels. Recently, rotary wing aircraft with electric powertrains and hybrid powertrains have appeared. Hybrid systems typically combine an internal combustion engine with an electric machine, while electric power systems rely entirely on the electric machine. [0003] Advantages of hybrid or fully electric powertrains over conventional internal co...
