Unusual military equipment.

According to most people, the helicopter is a large aircraft that use the millionaires and the military. Just some of the aviation enthusiasts know that these cars appeared 110 years ago, and the first copies were a fragile unreliable design. But just after half a century, Soviet engineers built the largest helicopters in the world.

1. Helicopter Field Root

110 years ago, 3 (according to others 13) of November 1907 in the sky up the first helicopter. The device is capable of taking off vertically, was known before, but that the design of the French locksmith Field Root (Paul Cornu) were able to raise man above the ground. The Bud earned a living repairing bicycles, and he had a knowledge and skills how to bring in a metal your idea.

Tubular frame helicopter became the basis for two rotors mounted in tandem. Between installed engine power of Antoinette 24 HP Output shaft of the motor led rotor with 22-metre belt.

Along with a test pilot helicopter weighing 330 pounds lifted off the ground 0.5 m and stayed in the air for about 20 seconds.

2. De Lackner HZ-1 Aerocycle

Experimental helicopter de Lackner HZ-1 Aerocycle first flew in 1954 and has shown itself as a very effective transport for one person. Development like the us military and after a lot of tests were produced in small series machines.

The basis of design – vertical shaft with two coaxial propellers, an engine-driven with 40 HP That was enough to lift into the air the device is equipped with a soldier on Board weighing up to 200 pounds.

Helicopter very easy to fly and stable in motion. To learn to fly, young men were required from 5 to 20 minutes of training. In large-scale production de Lackner HZ-1 did not hit, as happened several serious accidents that are typical for helicopters with coaxial rotors: 2-meter blades sometimes hurt each other.

3. Ka-56

Ultralight helicopter Ka-56 “Wasp” began designing in 1971 for the needs of the Armed Forces of the USSR. The device is made collapsible, it is full Assembly by one person takes just 15 minutes. In the design of the “Wasp” is applied to the oppositely rotating blades, which helped to remove the tail rotor. Take-off weight of the Ka-56 is only 220 pounds.

The rotary-piston engine with 40 HP was to allow the pilot to fly at speeds up to 110 km/h and climb to an altitude of 1700 meters. Unfortunately, the program Ka-56 was cancelled.

4. Mi-12

The Soviet Union has always sought to be ahead of the rest, and it is not surprising that the world’s largest helicopter designed by the engineers of OKB M. L. Mil. Aircraft V-12, also known as Mi-12, first flew in 1968.

When empty, the Mi-12 weighed 69 tons and could carry a payload of up to 44 tons. This figure is still the world record of carrying capacity among the helicopters.

Unique machine dimensions and an innovative design on the spot struck by foreign experts attending the International Airshow in Le Bourget in 1971.

It was built 2 Mi-12, one of which can be seen today in Monino near Moscow.

5. Mi-10

The Mi-12 was the precursor of that his appearance attracted considerable attention. The Mi-10 was first flown in 1960. Machine with a length of 42 meters were equipped with long undercarriage and could carry under the fuselage to 15 tons of cargo. In the 1960-ies the main work for the Mi-10 was the movement of ballistic and cruise missiles.
