Ka-56 - this ultra-light helicopter. The need for such aircraft has arisen in the x and 40-50-ies. The whole world is looking for a solution to actively create data helicopters. In the Soviet Union, this work has begun NI Kamov.

Under the leadership of Nikolai Ilyich 1946 it was designed and created the first Soviet single Ka-8 called "from Irkutsk." In Tushino July 48 years to conduct an air parade was first introduced to this model. Journalists nicknamed him "air bike." The helicopter is designed on a circuit coaxial main rotors. Also, the engine capacity was installed 38 hp

Following the test flights secretary general of the Communist Party of the Soviet Union I was very surprised such a successful model and instructed N. Kamov Ka to create on the basis of single-8 helicopter reconnaissance nature. However, his main task was to monitor and support communication for Navy ships. Because of this, there is a need to create a new OKB Kamov (1948 year). After some time, the engineers have designed a new and much improved model Ka-10. To do this, a helicopter requested aviation piston engine AI-4G production famous designer AG Ivanchenko

Excellent aerodynamic efficiency is ensured by helicopter coaxial rotor. The tail rotor is completely absent. In turn, the aerodynamic symmetry of key interlocking screws exclude communication throughout the control system. It provided easy management techniques, piloting, increased maneuverability at low altitude and installed a small vibration of the helicopter. With this scheme (coaxial) and testing the designers and engineers of the OKB greatly ease the task of solving the problem of vibrations in the air machines.

Twenty years later, namely in 1971, the government set a target to its decision to scientists from EDO to develop an ultralight single Air Force helicopter to the interests of the Soviet Union. In turn, the project to develop trusted Fomin SI (Deputy Chief Designer). One of the main requirements to the machine it was designed so that the helicopter can be folded compactly into a cylindrical container with a diameter not exceeding 500 millimeters. It was necessary for fast and easy transport single unit.

Accommodation helicopter limited to submarines and surface vessels. Due to the operational status of the transport helicopter was driven over 15 minutes and only one person. It is also important condition was self-service model on a large distance from the place of deployment in long-term use. These requirements immediately outlined the model of the future military aircraft helicopter single - unit small and light form with the possibility of folding and without a lot of separated elements throughout the layout.

Ka-56

In the period of 1956 1957 year in America it held a contest to create a single helicopter. The tests were single-rotor "Hiller" and coaxial "Girodayn." In their experience, our designers have started to search for possible solutions to the layout of the helicopter. As a result, none of the OP class did not get into production due to a number of obvious problems. The only advantage of single helicopter was their easy razbiraemost.

Special Design Bureau decided to set up on the basis of Ka-10 new ultralight air unit scheme collapsible corner. He was named Ka-56 «Wasp". It differed from the established analogue rotary-piston engine, air-cooled, and the compound of the wheel chassis with an elastic tail wheel.

Many problems have been solved through the use of rotary-piston engine. In addition to using conventional motor fuel, to solve problems of dimensions, and therefore transportation. At the same time a conventional piston engine was less uniform and had the increased levels of vibration and noise. Also, much worse is started at low temperatures. The new engine was less dependent on the supply of fuel and oil on the borders, far from their places of permanent deployment.

During the construction of the future OP it was created a full-scale mock-up helicopter. On it with all the minute details worked out the major decisions on the arrangement and method of folding units or units of helicopter components. The prototype included all the basic modules: the engine coaxial carrier system, gearbox and fuel tank management. Units folded elements were made under the scheme odnopodvizhnyh kinematic pairs. And it was constructive, as were six couples who provide the entire process of unfolding and folding the helicopter in full operational status.

Only four rotor blades are detachable coaxial elements of the assembly. Joining blades made quick fingertip complete with spring latch acting as a preservative. With the exception of the blades, the remaining support system and management mechanism helicopter did not need adjustment work after deployment of the helicopter to operate. And thanks to the work done to simulate helicopter design engineers were able to achieve positive results with time spent on the collection and analysis of the manned helicopter for transport to the ready-to-use. The total time for the event was limited to 10 minutes with one person (the pilot).

Power piston engine was 40 hp, but that in any case did not affect the usefulness of the air machine. The total take-off weight was 220 kg and the lift into the air, in addition to it, the helicopter could 110 kg of cargo. Single helicopter could fly up to the mark 1700 km total distance was surmountable 150 km, and the maximum speed reached 110 km / h.

But the helicopter did not hit any flight testing or, respectively, in serial production. The problem arose because of the lack of the country's aviation engine rotary-piston type for low power.
