Modern tactics of warfare moves from the position of the ways of war to the remote. And, in the prevailing conditions, in the first place out reconnaissance with use of unmanned aerial vehicles. Thanks to their avionics becomes possible to obtain information about the enemy to determine the location of its forces, the movement of equipment and manpower. However, the use of UAVs allows to explore the electronic tools of the enemy to determine the range of operation of the various radio and radar search and targeting. The information obtained from drones allow the company to assess the situation and to adjust the fire ground weapons. Depending on the tasks the UAV can be reconnaissance and attack, to carry on Board different types of weapons. In the USSR, and in Russia for many years conducted the work on creation of various types of air drones as aircraft type, and in the form of small helicopters. Work on the helicopter-drones began in 1991. The main objective of the UAV was to perform reconnaissance functions. It depends on takeoff weight and payload. One of the first prototypes of remotely piloted helicopters was the development of a well-known manufacturer Russian helicopters firm "Kamov" - Ka-37S. Excellent performance demonstrated by experimental machines, may be used to perform a variety of tasks for military and civil purposes. Aviation robots are able to solve tasks in the interests of law enforcement agencies, defense Ministry and border service of the Russian Federation. Successful application of UAVs in the interests of the border service of the Russian Federation. Having such means of aerial reconnaissance, the guards will be able to view any remote places of the state border. A very wide range of applications of UAVs in the Navy: to conduct Maritime reconnaissance and anti-sabotage. In addition, the helicopter allows to carry out aerial reconnaissance of radiation, chemical and biological environment in the area of operations. UAV Ka-37S is, in fact, a flying laboratory. On Board is a whole set of complicated electronic equipment. All information about the terrestrial environment is recorded on a television camera which is relayed to a ground control station (NPU). To improve the accuracy of navigation and positioning of detected objects on K-37S all electronic equipment associated with a satellite navigation system. This allows reliable control of on-Board tools, automatic control system (ACS). Structurally, the drone is made in the traditional helicopters Kamov coaxial arrangement of screws. The UAV is compact and maneuverable, has a transport mobility. The fuselage is made of composite materials and duralumin alloys. The front compartment of the radio waves fairing is made of fiberglass. In the front compartment are placed the engines, which are based on the chassis and systems of the helicopter. Traditional helicopter tail boom has a conical shape with two vertical stabilizers. The movement of the device give two piston engine P-037. Each engine has its own fuel system, ignition system and cooling. Fuel tanks made of aluminum with a capacity of 13 liters. Power supply system of the helicopter is receiving power from the DC generator and ensures the efficiency of equipment Ka-37S and an automatic control system (ACS) and units of radio equipment. Onboard equipment control drone functionally associated with all the controls and the ground station. Commands from earth's radio signals are converted to electrical signals, issue commands to the controls of the machine. This is possible thanks to placed on the UAV OBC. The whole complex both ground and on-Board equipment allows the operator on the ground to completely control the whole process of flight of the helicopter from takeoff to landing, to manage them. And along with this to fulfill the tasks of an intelligence nature. The automatic control system is able to perform automatic flight, pre-entered into the OBC software. Sitting on the ground, the aircraft operator performs an operation with the remote control console which controls are available. At the same time, on the offset screen operator displays the entire terrestrial environment, which comes with the camera helicopter in real-time. Interestingly, before takeoff, control of the drone via a wired channel, and after take-off – only radio. To move the UAV complex to different destinations use a special shipping container, which houses the helicopter and all control equipment.
