  • a drop denotes a shape that is derived from a liquid body that detaches from a larger liquid body. This shape is different from a shape of a drop in the rest state with a homogeneous liquid and homogeneous external medium, since such a drop has a spherical shape in the rest state and in a homogeneous environment and thus has a circle in cross section.

  • a lower side of the channel is formed by means of the nacelle housing, the lower side of the channel being in particular curved. Due to the curvature, which reflects a type of circular section, the cylindrical shape of the electric motor is followed. Both the electric motor and the gondola housing have a cylindrical basic shape.
  • an upper side of the channel lies opposite the lower side of the channel, the upper side of the channel being in particular curved. If the upper side as well as the lower side of the channel are curved and the curved surfaces run approximately parallel, a channel for the flow of water results which essentially has the same height in a longitudinal direction.
  • a first guide structure for water guidance and a second guide structure for water guidance are provided, the first guide structure and the second guide structure being spaced apart from one another in a longitudinal orientation and a longitudinal orientation.
  • the guide structures can be fastened to the shaft and / or to the nacelle housing. This allows the lead structures to perform a support function if they are attached to the shaft and the nacelle housing.
  • the guide structures are also provided for guiding or guiding the water within a channel which is being formed and outside this channel. The complaint results in openings for water to pass through. Water can enter or exit the channel through the openings. The shape and size of the openings can influence the voting behavior inside and outside the channel.
  • the support structures together with the guide structures, form a partially imaginary common outer basic cross section in one embodiment of the drive device.

  • the flow of water can be made possible when the drive device is at a standstill and / or when the drive device is moving.
  • water flows along the drive device and thus along the supporting structure and / or the nacelle housing and / or along the guide structure.
  • the openings can be designed so differently that different openings allow different flow rates at different speeds.
  • a first opening has a first opening cross section, which narrows. Due to the narrowing, a higher flow rate of the water can be achieved.
  • a blocking effect can also be achieved. The blocking effect can arise behind a body that is exposed to the flow. If the flow comes from the front, the side / middle openings lie in the "shadow" of their upstream side supports or guide supports.
  • the guide support can also be referred to as a guide structure. The flow tears off at the rear edges of the frontal flow openings and begins to swirl, the resulting swirls block the opening behind the side support.
  • At least one of the guide structures has a trapezoidal cross section on.
  • the trapezoidal cross-section can influence both the opening adjacent to the guide structure and the flow behavior of the guide structures.
  • At least one of the guide structures has a parallelogram-shaped cross section.
  • the trapezoidal cross-section can also influence both the opening adjacent to the guide structure and the flow behavior of the guide structures.
  • At least one of the guide structures has an outer side surface which is larger than the inner side surface of this guide structure. It can thus be achieved that the length of the outer side surface is greater than the length of the inner side surface. A surface that is as flat as possible is thus achieved in the outer region.
  • the openings are then modeled in particular in that the length of the inner side surface is shortened compared to the length of the outer side surface.
  • the inner side surface and the outer side surface are largely parallel to each other.
  • the first guide structure has a first longitudinal orientation and the second guide structure has a second longitudinal orientation, the first longitudinal orientation and the second longitudinal orientation being inclined differently to the longitudinal axis of the drive device.
  • guide structures form pairs, the pairs being mirrored in each case on the longitudinal axis. The parts of a pair are thus reflected with respect to the longitudinal axis.
  • the first support structure and the first guide structure overlap with respect to their position on the longitudinal axis of the drive device. This means that less eddies are formed and the flow behavior is improved.
  • openings and / or guide structures are designed such that they inhibit a flow during nominal operation of the drive device. It can thereby be achieved that a stable flow can develop in the channel.
  • the electric motor of the drive device can be cooled by this flow. A high flow of water through the channel improves the cooling effect and thereby increases the performance of the electric motor.
  • a flow velocity of the water surrounding the drive device is generated, which reduces a flow through openings of water.
  • the generation of the flow speed takes place, for example, by the movement of the ship, which results from the natural flow of the water, as well as from the drive power by the rotating propeller of the ship. If the flow of openings through water is reduced, the water flow is inhibited. If a channel in an upper section of the nacelle housing has a multiplicity of openings which are distributed in a longitudinal direction, the inhibiting effect relates in particular to the openings which are located between a first opening in the longitudinal direction and a last opening in the longitudinal direction. Due to the inhibiting effect, the coordination behavior of the water in the sewer is improved.
