Helicopter model Ka-60 is a multipurpose device the Russian production, which was originally to be used for military purposes, namely to transport arms and ammunition in the pockets of military conflicts. As it relied exploration and rescue operations. He served as an excellent vehicle for training pilots. And in the further development it has found application in civil aviation.

The Ka-60 Designing in the USSR was started with 1983 of the year. At that time there were many models and modifications of Mi, who deservedly filled all areas of civil aviation, and meet the needs of the Army. Despite, Mil helicopters that had greater carrying capacity, this was their shortcoming in the carriage of goods by up to two tons, because it was uneconomical. The main part of all cargo transported Mi-4 model, but they were taken out of production, This was the impetus for the creation of a more economical helicopter with the right for the time qualities and characteristics.
The first prototype of the Ka-60 at MAKS-2003
To solve this problem, a decree was issued in the summer 84 on the establishment of the machine, which could carry high quality goods at any time of day. Won the contest for the design of the Kamov bureau. This machine was to transport goods across the battlefield. Draft helicopter Ka-60 project was completed in 1990 year, The first machine was built only in 97 year. Such a great time of construction of the machine was due to the collapse of the Union and the lack of funding for the project. The first presentation took place the device in the middle of summer 1998 on the territory of the firm Kamov. During the appearance he was named "Killer Whale". The first separation from the helipad helicopter has carried out the same year the winter. For a more complete examination was made even one helicopter.
Orcas production planned for helicopter plant in Ulan-Ude, but eventually they began to produce in Lukhovitsy near Moscow. The Russian Defense Ministry has made an order for production 100 helicopters of this model, mass production scheduled to begin in 2015 year.
Features of the Ka-60 Killer Whale
The first feature can be called, that the helicopter was manufactured on single-rotor scheme, which is unusual for the Kamov bureau. This scheme was chosen, to provide a large cargo cabin of the helicopter and flight speed is quite high. The latter was also obtained by the use of new technologies in the production of rotor blades and, which has excellent aerodynamics in flight. To reduce the weight of the blade-Ka 60 are made of composite materials, that, in its turn, are much longer.
The new machine has an elongated body, which enhances its streamlined. Better aerodynamics and contributes to the, that the helicopter can put the chassis. A novelty is also the tail rotor, which is located in the annular channel at the tail. It is the structure of the tail rotor has been chosen due to the fact, most of the time the helicopter will be in level flight, and not hang in the air.

Application and design
As mentioned earlier, the main task of the helicopter is to transport military cargo on the battlefield. But he can perform the functions of rescue, health, patrol, reconnaissance vehicle. The Ka-60 is also used to train pilots and transport VIPs.
This unit has a higher safety performance from the use of a large number of composite materials, as well as due to the fact, that all the "Orcas" system dubbed. The helicopter is equipped with wheel chassis system, which provides an effective energy absorption during landing. For a more soft and comfortable fit a helicopter equipped with a shock-absorbing seats passengers and pilots. The helicopter has a system, which help to reduce its visibility in the infrared spectrum.
The forward fuselage arranged cockpit, and the middle part of the machine is represented as a power unit housing scheme. The middle section is placed cargo compartment, which has doors on each side, in the same section are placed and fuel tanks. Besides, to that of the helicopter body there is a power unit and the chassis.
This housing structure is made of a large number of composite materials, which are fastened to the joists. The tail boom apparatus in many parts made of composite materials. The beam pattern projected by monocoque. On the beam mounted fairing, a transmission shaft located therein, which drives the tail rotor.
Model helicopter Ka-60 manages one pilot, and his place is on the right side, that distinguishes it from all domestic models. This pilot's side was chosen, pilot to the left hand to carry out the work with monitors, which show the operation of the systems. And on the right side of the pilot machine a control lever is placed. Training machine of this type has paired control system.
Empennage Ka-60 is a fixed stabilizer, at the end of which are mounted stabilizing surfaces, which are represented by special washers. Kiel tail and tail rotor made separate monolithic module, which may be attached to the tail boom via connecting frames. Keel machine is made of new composite materials, but they are fixed to the inner frame of the machine.
Helicopter landing gear of this type consists of three poles: two front (major) and a tail. Front feet are made of a lever system, they are equipped with brake systems. Rear landing gear is made by telescopic scheme, and it is not equipped with brakes. All of the landing gear system is aimed at damping vibrations and shocks when landing and landing calculated even when the vertical descent rate 6 m / s.
Power plant Ka-60 represented by a pair of gas turbine engines RD-600V model, which have been developed by designers Rybinsk Bureau, which deals with Motors. To start the powerplant exists auxiliary engine AI-9. All these units of the power plant are located above the main cabin of the machine in a special gondola and are attached to the fuselage. In this structure also housed the main gearbox and gearbox drive unit.
All fuel helicopter is four tanks, in which seats 1120 liters , they are placed in the floor of the cargo compartment. All tanks are interconnected spigots, which can carry fuel pumping, and a powerplant fuel passes due to the electric fuel pump of the centrifugal circuit. On the stretch, or for long-distance flights it is possible to install an additional two external fuel tanks, in which you can put more 390 liters.
The main screw consists of five lobes, which prevent the occurrence of noise. Due to elaborate optimization screw turning speed emits significantly less noise. The blades of both propellers made of strong composite materials. For blades were thought out system, which prevents them from ice. The tail rotor enclosed in a ring-type channel, screw itself represented a fan, which is equipped with 11 blades. He has a system, which changes the inclination angle of the screw.
test
The first prototype of the Ka-60 (board room 601) It made its first flight 10 December 1998 of the year.
AT 2007 year began testing a second machine (board room 602).
23 June 2010 the year the first experimental helicopter (601) It was destroyed during a forced landing between cities Dzerzhinsky Kotelniki and in Lyubertsy district in Moscow.
