Aerial device

摘要

The present invention consists of an aerial device, comprising a structure and a rotating element equipped with at least one blade, suitable for effecting a rotation relative to the structure around a rotation axis, wherein the device is equipped with means making it possible to cause the rotating element to rotate relative to the structure and wherein these means include a gas generator and a pipe that makes it possible to guide the gas towards an orifice at a distance from this rotation axis in order to cause the rotating elements to rotate by means of the gas ejected through the orifice, characterized in that the generator outlet and the pipe are part of the rotating elements and are suitable for rotating around the rotation axis relative to the structures.

1. An aerial device, comprising a structure and a rotating element equipped with at least one blade, suitable for effecting a rotation relative to the structure around a rotation axis, wherein the device is equipped with propulsion means to cause the rotating element to rotate relative to the structure and wherein these propulsion means include a gas generator fixed in the structure such that the gas generator does not rotate with respect to the structure and at least two pipes for guiding a gas produced by the generator towards at least two orifices at a distance from this rotation axis in order to cause rotating elements to rotate by means of the gas ejected through the orifices, characterised in that the device is equipped with at least first and second motor arms, each of which extends in a direction that is essentially perpendicular to the rotation axis and wherein one of the pipes is positioned in each of the motor arms in order to guide the gas towards the orifice in each of the motor arms, wherein the device further comprises a gas distribution arrangement that forms a connection between the gas generator and each of the motor arms, the gas distribution arrangement being configured to pass the gas produced by the generator towards the motor arms, the gas distribution arrangement and the motor arms being part of the rotating element and configured for rotating around the rotation axis relative to the structure and the gas generator in order to eject the gas from the generator directly into the motor arms, wherein the gas distribution arrangement comprises first and second opposite facing elbows that rotate with respect to the gas generator, the first and second elbows being first and second separate pipes, each having a substantially cylindrical cross section, wherein the first and second pipes are offset from each other in a direction perpendicular to the rotation axis and wherein the first and second pipes form an offset Y where the first pipe forms a first branch of the offset Y and the second pipe forms a second branch of the offset Y that is not co-planar with the first branch, the first pipe including a single bend between an outlet of the gas generator and an inlet of the first motor arm, the second pipe including a single bend between the outlet of the gas generator and an inlet of the second motor arm, wherein the first pipe forms a first path for the gas that is separate from a second path for the gas formed by the second pipe over substantially an entire volume between the outlet of the gas generator and the inlets of the motor arms, the first and second paths being respectively and separately enclosed by the first and second pipes, wherein the outlet of the gas generator is connected directly to an inlet of the gas distribution arrangement.
