The present invention relates to the provision of air navigation platforms used for forming a wireless data transmission through the line of sight in a given geographic area.

Wireless broadband networks are virtually no competition on the speed of deployment for geographic areas in which a large area combined with a low population density, broadband wireless solutions are of particular importance, as they allow cost-effectively and quickly build telecommunications infrastructure in the wider landscape.

The use of aerial platforms provides telecommunication coverage of large geographic regions. Simultaneously with the establishment of a regional data networks, voice and video high-altitude platforms can be used for the purposes of surveillance within 70-80 km (e.g. in border areas or monitoring of traffic flows), forest fire detection, environmental monitoring using sensor networks, geological and geophysical investigations, radiological control, etc.

The duration of navigation when using high altitude platforms regional networks at altitudes up to 1 km in the natural environment on public p is stranstvo determines the priority tasks of ensuring the reliability of the operation and management of air platforms, including the availability and cheapness of energy resources supply their propulsion systems and instrumentation systems.

One of the most important tasks in ensuring navigation of unmanned aerial vehicles when used on an industrial scale is to optimize the number of steps of converting the available energy resources in the vertical component of the thrust of the aircraft.

Know the use of helicopter propellers, for example, in unmanned helicopter of the German firm "Domier DO-32K "Kibitz", in which two turbocharged engine "cold cycle" are used to create a lifting rotor thrust. However, turbojet engines run on liquid fuel (kerosene, gasoline), which is fed under high pressure and ensures functionality of the system within a relatively short time of operation. Due to the hydrostatic pressure of the fluid hose becomes thick and therefore heavy (especially with liquid)that does not apply in the case of long-term use of the aircraft for navigation aerial platforms wireless communication systems. Accommodation turbojet engines for aircraft decrease the weight of the necessary equipment aerial platform.

Know the use of a flexible shaft for transmitting krutwig the moment (RF patent No. 2197403, publ. 2003.01.27) in the transmission control system two-piece articulated all-terrain vehicle. Known flexible shaft made of composite material (RF patent No. 2146019, publ. 2000.02.27) and flexible shaft containing a means for transmitting torque and rigidly connected to the latter end valve, in which the means of torque transmission is made in the form of a cylinder formed by interlacing bundles of wire of circular cross section so that each successive beam encircles the previous in the opposite direction (patent RF №95106132, publ. 1996.11.27). Known flexible shaft, made in the form of a rod or tube of flexible material which is connected to and communicates elastic frame, consisting of a cylindrical spring fixedly connected on the ends of the two sleeves and positioned in the shaft hole of the flexible longitudinal rods connected to the bushings. Known flexible shaft has a fairly complex structure, it is difficult to collect. All this reduces the reliability of the known flexible shaft (patent RF №2097611, publ. 1998).

Known special form of execution of the flexible shaft, for example, contains a flexible membrane located therein a working medium, which represents the filling tightly Packed granular material, while the flexible sheath is made in the form of a tube of the flexible material, reinforced in the mass of the grid frame made of flexible filaments, winding angle of the filaments of the frame to the generatrix of the cylindrical surface of the shell constituting 45±5°and the particles of the bulk material have a spherical shape with a calibrated diameter lying in the range of not less than 100 μm and not more than 1/5 of the inner diameter of the flexible sheath, the flexible strands are made of silk or nylon, or carbon fiber, while the inner cavity of the flexible membrane filled with grease and sealed, and the maximum surface roughness of the particles of the granular backfill material does not exceed 12.5 μm (patent RF №2256825. publ. 2005.07.20).

All of the above forms of execution of the flexible shaft, with all the specific deficiencies are also common, namely, low reliability due to their complexity and relatively small length with a relatively large weight, which does not allow to use these technical solutions for lifting and navigation of aerial platforms.

The closest analogues are the way of the formation of regional wireless transmission of information that is implemented in telecommunication aerial platform (patent RF №52296 for a utility model publ. 10.03.06,). The feature of the method of formation of the regional wireless transmission of information, including razreshenie air Telecom is operating platforms at predetermined heights by creating a lifting force for retention in specific points of the regional network geographic region and stabilize the position of the platforms at these points, is that the lift force for each platform create with remote and/or Autonomous manned rotary-wing aircraft due to the vertical component of the thrust vector of its screw, and the retention of this aircraft and platforms at a given point regional network geographic region carried out by associating them with a given surface point geographic region flexible shaft, which is used as the channel of the power supply to ensure the rotation of the propeller of the aircraft. Lifting platforms provide, for the promotion of the screw below the surface, and when the desired height is required torque screw rotation generated by the engine of the aircraft. Stabilization of the position of the platform provide due to the inertial navigation of the aircraft at a given point regional network geographic region.

The disadvantage of this technical solution is that the use of a flexible rod with a feed channel energy supply requires the use of power converters power in the torque of rotation of the propeller of the aircraft placed at the specified altitude navigation platform that reduces its payload.

The technical result of the invention zaklyuche is to increase functionality and improve the reliability of lifting and navigation aerial platforms telecommunication network by simplifying the hardware implementation of technical solutions.

This technical result is achieved in the way of rise to a predetermined height and provision of air navigation platform wireless transmission of information, including creating a lifting force rotary-wing aircraft, the rise associated platform wireless transmission of information at a given height, and the hold of the aircraft and platforms at a given point of the surface of the geographical region of the flexible shaft so that as the flexible rod used housed in a cylindrical shell, a flexible torsion bar with length not less than the prescribed height placement of the platform, whereby it is rigidly secured one end of a torsion axial element rotation propeller aircraft and reported by torsion screw torque required time to create a lifting force aircraft, after raising the platform to a predetermined height is fixed to a second end of the torsion on the output shaft of a source of torque, and in the process navigation platform required torque of the propeller of the aircraft reported by the torsion bar.

In addition, as a flexible torsion can use the cable from a synthetic material such as Dacron.

This technical result in the device to rise to a predetermined height and ensure the navigation is the aerial platform wireless network transmission information, containing the stations transmit and receive signals in the predetermined geographic region associated with the aircraft, pulling the screw and connected with a flexible shaft, the second end of which is fixed with the possibility of changing the length of thrust at a given point of the surface of the geographical region, is achieved by the fact that it introduced a hollow body with two mutually perpendicular holes and the contact circuit of the torque transmission that is installed in the cavity of the housing for axial movement and rotation relative to the vertical, while the flexible rod is made in the form housed in a cylindrical shell, a flexible torsion, the upper end of which is rigidly connected with the axle of the traction screw, and the bottom is provided with a coupling made with the engagement element for connection with a source of torque, and a flexible rod is extended through a perpendicular hole of the body and trailer chain transfer torque has elements for engagement with the specified coupling and source of torque.

The invention is illustrated by drawings.

Figure 1 shows a structural diagram illustrating the proposed technical solutions at the initial stage of lifting the aerial platform.

Figure 2 - structural diagram illustrating the proposed technical solutions at the stage of navigation without the SCE platform.

Device for lifting at a predetermined height and provide navigation rotary-wing platform includes a housing 1, which is made of two mutually perpendicular holes, through which the cylindrical shell 3 and placed it with the possibility of axial rotation of the flexible torsion bar 2. Additional housing bore in its cavity 15 is mounted on the shaft 10, the slider 4 with the possibility of vertical movement along the cavity and the axial rotation around the vertical axis. The first (upper) end of the torsion bar is rigidly connected with the axle of the screw 6 of the aircraft 7 carrying the station 5 of the transmission and reception of signals in a given geographic region of the rotary-wing platforms. The trailer has 4 end item 8 (e.g., splined) for transmission of torque, and the second (lower) end of the torsion bar 2 is rigidly connected with the coupling 9 having end element for receiving torque. In addition, the contactor 4 and the output shaft 13 of the engine (source torque) made with elements, respectively, 11 and 12 transmit torque in mutually perpendicular directions (e.g., bevel gears). The output shaft 13 also has a mechanical element (not shown)for the direct transmission of torque to the coupling 9 torsion, similar end item 8 of the trailer.

The receiving station and lane is giving signals in the predetermined geographic region is made in the form of a base station of wireless broadband access systems and may also include (not shown) battery, voltage converters, secondary power supplies, video surveillance.

The operation of the device is as follows.

During lifting (1) the torque is transmitted through the chain from the shaft 13 of the engine (source torque) on the screw 6 through the elements of the gearing output shaft and the coupling hub 9, the rigid connection of the coupling halves and the first end of the flexible torsion 2, torsion bar, rigid connection of the second (upper) end of the flexible torsion with the axle of the screw 6. The lift force is generated air traction screw 6 and under its action rotary-wing platform with the aircraft and station transmit and receive signals up to a predetermined height navigation. Flexible torsion shell stretch lifting force through the horizontal and vertical openings, and a source of torque is in constant contact with the torsion bar. When the platform height output drive source torque and the coupling half open and the contactor is moved vertically upward, engages in the vertical direction with the coupling, 90° in the vertical plane under the action of the lifting force, and horizontal - shaft engine (source torque) through the elements 11 and 12 transmit torque in one of perpend the molecular directions (bevel gear). In the navigation process (figure 2) platform necessary to screw the flying machine the torque is transmitted through the chain from the shaft 13 of the engine (source torque) on the screw 6 through the elements 11 and 12 of bevel gears, splined end elements of the contactor 4 and the coupling 9, the rigid connection of the coupling halves and the first end of the flexible torsion 2, torsion bar, rigid connection of the second (upper) end of the flexible torsion with trunnion screw 6.

Transmitted power in this case will be:

P=MCR·ω.

Feature is the fact that the torsion bar must be flexible, because at the initial stage the entire length of the torsion bar is horizontal, and the resulting vertically. In this case, it is advantageous to make the torsion bar more flexible, increasing the angular velocity (ω), slimming (MCR), while maintaining a given power (P). However, the angular velocity of the helicopter screws are small and direct transmission of torque (no gears) may be ineffective. The use of gearboxes is an effective means of transmitting mechanical power, but increase (multiply) problems with time. The fact that in addition to the transmission of the rotating torque on the screw, with the increase in (ω) are increasing problems with friction torque. This particularly affects the inflection point of the torsion radius (R), where the torsion bar must be placed in the so-called "shirt". Friction is the same in the shirt can be calculated as follows

where ϑ=Ucf,

τ - tension friction

dn=δ - the gap.

The formula for the dimension:

The moment of resistance to rotation (i.e. friction):

MT=FT·r; FT=τ·S, where S is the surface area of the torsion bar, dressed in the shirt, r is the radius of torsion. Then we have:

Will appreciate this moment in numbers when r=1[mm]=10-3[mm] (d=2·10-3[m])

l≅2[m]; δ=0,1[mm]=10-4[m];

Now we can estimate the tension in the torsion bar, if we transfer power

When

I.e. friction at a given angular velocity can be ignored, because M>>MT.

To calculate the strength of torsion (τMor) we have:

where:

It is necessary to reduce (τ) about 500 times. The easiest way this can be done by increasing (d) about.

This means that d≅16 mm and a weight of 1 m of this cable from Dacron will be:

When N=100 m; (mg)l=2,83[the g], when the weight of the platform 50 kg - this will amount to 5.7% of its weight.

When N=200 m (mg)l=5,66 [kg]that will be ˜11.4% of its weight.

These indicators can be improved, if you apply as a torsion bar is not solid diameter, and pipe. The diameter ratio of the pipe ⊘D and ⊘d is selected experimentally based, to blend the radius R of the pipe is not formed. The engine in this case is on the Ground and its weight does not matter.

The weight of the casing will depend on the ratio of the density (ρ) and strength [σ] the material of the shell. These parameters are listed in table 1 for the different materials from which to fabricate hoses.

Table 1

4Polyamide - 681,15-6-60 to+120
5 Polyester (nylon)1,4111-12-
6Fiberglass laminate1,816-33-60 to+130

For approximate calculations we take the simplest of table 1 material - polyethylene:;;.

The calculation showed that at 20 fold the stock, the wall thickness of the hose is equal to δ=0,2 mm

Hence the mass of 1 m of hose will be:

The entire weight of the hose when N=200 m will be:

It is possible to estimate the so-called height samovytaskivaniya hose made of this material are:

m=ρSH, and the weight P=γSH;

Where:

Thus, the height H=200 m, this material uses only a fifth of its strength. The strength calculations from other types of loads you have to maintain on the basis of the remaining 4/5-part, i.e. from 0.8 to[σ].

A similar feature for other materials are given in table 2.
