METHOD FOR COMPOSING WIRELESS INFORMATION TRANSFER NETWORKS AND A HIGH-ALTITUDE ROTARY-WING PLATFORM FOR REALIZATION OF THE METHOD Russian patent published in 2008 - IPC H04Q7/00 

FIELD: navigation devices of aerial platforms used for composing wireless information transfer networks and working within range of direct visibility in a given geographical location.

SUBSTANCE: method for composing wireless information transfer networks includes positioning aerial telecommunication platforms at given altitudes by creating a lifting force for keeping them in given points of regional network of geographical location by means of remotely and/or autonomously piloted aircraft, which is kept in given point together with the platform by means of connection to given surface point of geographical region with flexible traction, which is used as a channel for feeding electric power energy to ensure creation of traction vector of aircraft, in accordance to the invention, as electric energy supply channel of the flexible traction an electric conductor is used which may be separated in its middle part, and to ensure lightning protection of information transfer network ends of electric conductor separation section are distanced for not less than value L_br, which is derived from formula , where E_th - average intensity of electric field in thunderstorm clouds, E_br - intensity of electric breakdown of air, H_al - altitude at which the aircraft is positioned. The high-altitude rotary-wing platform contains a station for receiving and transmitting signals in given geographical location, mounted on an aircraft which has instrument bay and screw propeller in form of electric motor with reducer and traction screw, and connected to a conductor-and-support cable by means of biaxial cardan suspension, second each of the cable is fastened with possible change of cable length in given point of surface of geographical location, and is connected to electric energy supply at that point and has no less than one electro-isolated current conductor for supplying electric energy to electric motor of screw propeller, in accordance to the invention, current conductors are made with separable connector in middle part of cable length with possible movement of at least one end of separable connector along the cable and fastening of separable connector ends at a given distance from each other. Coaxial conductor-and-support cable may contain at least two mutually mobile electro-isolating elements, one of which is in rigid connection with first end of separable connector of current conductor of the cable, and the other one - to second end of separable connector of current conductor. Electro-isolating elements may be positioned inside the coaxial conductor-and-support cable under the layer of external climatic and mechanical protection and/or under isolating layer with possible movement of at least one electro-isolating element along aforementioned layers. External climatic and mechanical protection layer may contain at least one lightning-draining channel, grounded in given point of surface of geographical region.

EFFECT: increased reliability of navigation of high-altitude platforms of telecommunication information network due to increased lightning protection of power supply channel.
