Description

The invention relates to the field of vertical takeoff and landing unmanned aerial vehicles and can be used for navigation of tethered high-altitude platforms in hover mode. A method is known for lifting an aerial platform of a wireless data transmission network to a given altitude and providing navigation, and a device for implementing the same (see RU 2315955 C1, 27.01.2008), which includes creating a lifting force for a rotary-wing aircraft, lifting the wireless data transmission network platform associated with it to a given altitude, and holding the aircraft and platform at a given point on the surface of a geographic region using a flexible rod, wherein a flexible torsion bar with a length no less than a given altitude of the platform placement, placed in a cylindrical shell, is used as a flexible rod, wherein one end of the torsion bar is first rigidly fixed to the axial element of rotation of the aircraft propeller and the necessary torque is communicated to the propeller by means of the torsion bar to create the lifting force of the aircraft, after lifting the platform to a given altitude, the second end of the torsion bar is fixed to the output shaft of the torque source, and during the navigation of the platform, the necessary torque is communicated to the propeller of the aircraft by means of this torsion bar. According to the invention, a hollow housing with two mutually perpendicular openings and a torque transmission chain closeer installed in the housing cavity with the possibility of axial movement and rotation relative to the vertical are introduced into the device for lifting to a given height and providing navigation of an aerial platform of a wireless information transmission network, wherein the flexible rod is made in the form of a flexible torsion bar placed in a cylindrical shell, the upper end of which is rigidly connected to the journal of the traction screw, and the lower end is provided with a half-coupling made with an engagement element for connection with a torque source, wherein the flexible rod is pulled through mutually perpendicular openings of the housing, and the torque transmission chain closeer has external splined gear teeth for engagement with a torque source having bevel gear teeth. The disadvantage of this known method can be considered the low quality of the platform navigation process due to insufficient elasticity of the torsion bar. A known system for controlling the trajectory of an aerostat (see RU 2238217 C2, October 20, 2004) is a device implementing this system, designed as a wing that generates lift. It is suspended vertically from the aerostat by a long cable and is designed to utilize the naturally varying force of the wind at various altitudes. The wing is capable of generating horizontal lift, the effect of which can be deliberately varied over a wide range of angles. This force is transmitted to the aerostat via the cable. This force allows the aerostat's trajectory to be varied depending on the ratio of the aerostat to the wing. Relatively little power is required to control the system, generated, for example, by a rudder, since the control force is generated primarily by wind energy, which performs most of the necessary work. The disadvantages of this system include instability and low maneuverability, which directly stem from problems with controlling the balloon's trajectory. A method for providing navigation for tethered aerial platforms of wireless data transmission networks and a tethered aerial platform for implementing the same (variants) are known (see RU 2315954, 27.01.2008), including generating lift for an aircraft to position a platform associated with it at a given altitude and maintaining the aircraft and platform at a given surface point using a flexible rod used as a power supply channel to generate a thrust vector for the aircraft's lift force. According to the invention, a gaseous working fluid is used as the energy carrier for generating the power supply energy. This gaseous working fluid is pumped under pressure into the power supply channel of the flexible rod, and at the outlet of this channel, the energy of the gaseous working fluid is converted into energy for generating lift for the aircraft. To generate lift for the aircraft, the energy of the gaseous working fluid in the form of fuel or natural gas can be used, and at the outlet of the power supply channel, it can be converted into electrical power or jet thrust. The disadvantage of this well-known technical solution is the complexity of the process of creating lift using a gaseous medium and the high fuel consumption, which can affect the efficiency of the aircraft and its environmental friendliness. The technical result of this system is to simplify the process of tracking the positioning of a multicopter high-altitude tethered platform. The technical result is achieved in that the tracking system for positioning a multicopter high-altitude tethered platform comprises
