Mi-10

 

 

In winter 1958 years of government decree in the Soviet Union started to design a new machine that could transport large loads. And it was a new project Mil design bureau under the name Mi-10. The new device has been created on the basis of existing Mi-6, but its peculiarity was that he could carry loads weighing tons in 12 250 distance in kilometers.

In the development of the project was added to the requirement for the transport of huge ballistic missiles. The new model of the helicopter remained completely the same powerplant as the previous model. Not changed, and machine control. The greatest metamorphosis occurred with the fuselage of the helicopter. The body of the helicopter was narrow and relatively low, but he had a passenger compartment length 16 meters, where it was possible to transport passengers 28.

For longer spans helicopter can be installed additional fuel tanks. Loads on the machine can be transported in two ways. The first - is transportation of containers with missiles, which holds grips with the hydraulic system. The second way - is shipping on the platform, which is attached to the landing gear.

The first Mi-10 (it was also called the design of the model in-10) off the ground in the summer of 1961 years. In the autumn of next year, this car made a record for lifting goods, he was able to lift a weight in 15 tons to a height of more than two kilometers. A year later, the project would do to close, due to the fact that the government refused to transport the missiles with the help of helicopters. At the time of failure of the project in 64 year it was made only 24 cars of this model. It is for this reason that the helicopter had little authority and was not in demand in the economy.

design Features

The helicopter is made of a single-rotor scheme with the tail rotor has four landing gear. The fuselage has a semi-monocoque design with cabin for two pilots in the forward fuselage. The cockpit has a very good visibility in all directions, allowing you to more accurately steer to produce goods. The cargo compartment has a very impressive size and is 60 m3. On the starboard side cargo door of the helicopter is available, which is installed near the winch, which can be used to lift loads of up to two hundred kilograms. To control the loading and mounting of goods under the cockpit mounted gondola with which pilots have a bigger and better view.

Chassis Mi-10 4 consists of racks, which are long and equipped with oil dampers. Each leg has two wheels and track chassis is 5 meters based in 8,75 meters. The tail boom of the machine is equipped with a safety support. The main screw machine is completely the same as had Mi-6, only to reduce it to tilt forward 45 '.

Mi-10 equipped with exactly the same powerplant as the previous model. Transmission also remained unchanged. This model has two fuel tanks, total capacity of which - 9 thousand liters. For large flight this device is equipped with extra fuel tanks, which can be placed on the chassis and on the sides of the helicopter. In addition, the machine spans impose additional tanks in the middle of the cargo compartment.

The equipment of the helicopter is the same as on the Mi-6. The new machine has a three-channel autopilot system. For rigid hold cargo transportation helicopter is equipped with fixtures and clamps, which operate hydraulically, management can be carried out from the cockpit. For continuous monitoring of the situation of goods vehicle is equipped with a television surveillance system.

General description and testing of the Mi-10

Due to the fact that all the units were taken from the previous model of the helicopter, and are not designed from scratch, a new model of the Mi-10 was ready within one year after the start of development. The tests of the new machine were quite successful, and has already 4-second flight was over a distance of thousands of kilometers 3. The first long flight was also successful during his helicopter to land to refuel. Flyers was established that this helicopter can transport cargo and equipment of different geometrical sizes with the help of the platform, which is installed between the landing gear.

1961, the spring model helicopter Mi-10 crashed on the way to Moscow from Kazan, killing all but the navigator. The accident happened because of the oil pressure in the engine, and the helicopter made an emergency landing with a large horizontal velocity. About the crash reported Mile, he and his military commission arrived at the crash site. The cause of the accident was the failure of the oil pump, which is mounted in the gearbox.

After this accident has been refined oil system on all future models of the Mi-10, in addition, a helicopter equipped with soft ropes. They are mounted outside of the case and served as a pilot for the emergency evacuation of the helicopter.

The first performance of Mi-10 the general public in the summer of 61 years the parade the Soviet Air Force. According helicopter was brought Geological house, which was installed near the podium guests and was used as a point of sale. In September of the same year, the helicopter set a world record: the Mi-10 15 able to lift tons of cargo to a height of 2,3 thousand meters.

Under state tests, the helicopter was tested for the transportation of various cargoes both inside the helicopter and using an external platform and mountings. In the tests on the external platform, buses, trucks and other equipment were transported, which itself could call the platform. In addition to self-propelled vehicles, the helicopter could easily transport standard railway containers. Despite the fact that most of the cargo that was not transported inside the helicopter created aerodynamic problems in flight, the helicopter still produced high-quality and fast transportation. Due to the fact that all the tests took place quite intensively, they ended even earlier than planned by the state commission.

The State Commission has given the green light to production and fly this machine. Has been confirmed safe shipping, mass is 15 tons. But while all were noted drawbacks of the machine. Experts have noticed a large enough body vibration at low speeds.

They also filed a claim to the established television system by which pilots were supposed to watch the loading and implement it. But in reality, the system could only show the fluctuations of goods during transportation and loading occurs almost blindly. In order to control the load, the pilot had to look out the window or even get out of the cockpit vents.

One advantage when loading was that the cockpit is placed very high because of the long landing gear. Due to this, the pilots were easier to inspect everything during loading. But long landing gear had disadvantages during takeoff and landing, as the helicopter really rocked on his stilts.

Serial production of the Mi-10 61 was adopted in the year, but in reality it was postponed several times. At this affected a decline in interest in the military-helicopter missile devices and technical malfunctions of the machine. Serial production of the new "scores" began in March 1964 years in the Rostov plant.

Mi-10 (product «60», NATO code: Harke) - transport military helicopter (flying crane), the development of Mi6. Designed in 1961-1964, adopted adopted 1963. Commercially available at the Rostov Helicopter Plant.

Mi10K- Mi10 civilian version, optimized to perform installation construction work.

20.02.1958 the Soviet government issued a decree to start the creation of a "flying crane" based Mi6. Quest provides 12t Capacity at 250km range and most (during transport for short distances) - 15t. In the process of creating a task completed requirements for transporting ballistic and cruise missiles, which was the main objective of the Mi-10.

Retaining control circuit and power plant Mi-6, designers replaced by a new fuselage vertolёta- low and narrow, which still fit into the compartment length 15.95m to transport goods or passengers 28; for spans it can be installed additional fuel tanks. To came off during takeoff at the same time all the wheels off the ground, the right landing gear made on 300mm shorter than the left, with the lowest clearance - 3.75m.
