. Gene Corporation has released the GEN H-4 personal single-seat helicopter. This aircraft consists only of a seat and chassis. Its main difference from conventional helicopters is that the GEN H-4 has 2 main rotors with common axis, which rotate in opposite directions (KA-52 Hokum). This helicopter does not need a tail rotor for balancing. In addition, it will be easy to park since the screws are only 4 meters long.

The helicopter is equipped with four lightweight two-cylinder 125 cubic centimeter engines running on gasoline. capable of rising to a height of up to 1000 meters, and its maximum speed is 90 km/h. Do not forget that in this mode the flight duration should not exceed 30 minutes.

In Japan, no special permit is required to fly the GEN H-4. According to the developers, controlling this helicopter can be compared in simplicity to driving a bicycle. A couple of hours is enough to learn how to operate the GEN H-4. It is not for nothing that the control of this helicopter has been compared to bicycles, since many of the controls are very similar to bicycle handles.

You will also be able to get an incredible feeling from assembling the construction set, since helicopter GEN H-4 sold unassembled.

Active work in the creation of ultra-light helicopters occurred in the 40s and 50s of the outgoing century. Our country was no exception, and the first who began to solve this problem was N.I. Kamov.

In 1946, under his leadership, the first single-seat helicopter in the Soviet Union, the Ka-8 Irkutsk, was built - an “air motorcycle,” as journalists called it after a demonstration at the air parade in Tushino on July 25, 1948. The helicopter was built using a coaxial rotor design with a 38 hp motorcycle engine.

After successful flights of the Ka-8 helicopter N.I. Kamov is entrusted with the creation at his base of a surveillance and communications helicopter for Navy ships. And in October 1948, a new helicopter design bureau was organized. N.I. Kamov significantly improves the design of the Ka-8 and creates a new single-seat helicopter, the Ka-10, but with an AI-4G aircraft piston engine designed by chief designer A.G. Ivchenko.

The coaxial design of the main rotors, due to the absence of a tail rotor, provided the helicopter with high aerodynamic quality, and the aerodynamic symmetry of the supporting system of coaxial rotors eliminated cross connections in the control system and made the technique of piloting the helicopter simpler, increased its maneuverability, and ensured a low level of vibration in the structure. The combination of these distinctive factors of the helicopter’s coaxial design was subsequently confirmed on subsequent helicopters from the Kamov Design Bureau of various weight categories and appointments.

In 1971, by decision of the Government, the OKB team was tasked with the development of an ultra-light single-seat helicopter in the interests of the Armed Forces of the USSR. The management of the work is entrusted to the Deputy Chief Designer Sergei Nikolaevich Fomin. According to Technical Specifications the helicopter had to be designed so that it could be stowed in a cylindrical shipping container with a diameter of no more than 500 mm. This requirement was determined by basing the helicopter on both surface and underwater vessels Navy and transportation to the place of operation by self-propelled vehicles through the torpedo tubes of ships.

The helicopter must be brought from transport state to operational state by one person within 15 minutes. And another important requirement is complete autonomy for long-term operation of the helicopter far from its home base. These requirements immediately determined the design concept of the helicopter - the helicopter must be foldable with a minimum number of detachable elements.

Various layout solutions were considered, and the experience of the Americans was studied, who in 1956-57 held a competition for a single-seat helicopter, in which helicopters with a single-rotor design from the Hiller company and a coaxial design from the company Girodain were tested. None of the helicopters were accepted for serial production, and these helicopters were only easily disassembled.

As a result of a large amount of calculation and design work by the OKB team, the Ka-56 Osa helicopter was designed according to the “warehouse corner” scheme with the pilot positioned in the same way as on the Ka-10 helicopter. The helicopter is equipped with an air-cooled rotary piston engine and a wheeled landing gear with a tail elastic support.

The use of an air-cooled rotary piston engine running on automotive fuel solved many problems, ranging from small engine dimensions compared to a conventional piston engine, more uniform operation and low levels of vibration and noise, resistance to starting in low ambient temperatures . In addition, the task of providing the helicopter with fuel and oils in conditions remote from its home base was simplified.

During the development process, a full-scale model of the helicopter was built, on which the main layout solutions and the design of folding units and elements of the helicopter were worked out to the smallest detail at the level of working documentation.

In parallel with the mock-up, a prototype of the main module of the helicopter was created - engine, gearbox, coaxial load-bearing system.

Structurally, the solutions for the units of folding elements of the helicopter were made according to the scheme of single-moving kinematic pairs, and there are only six such pairs that ensured the process of folding or deploying the helicopter into operational condition on the helicopter.

The detachable structural elements were only 4 blades of a coaxial rotor. The joining of the blades was carried out by a quick-release pin connection with a locking spring valve.

The supporting system (except for the blades) and the helicopter control system did not require any adjustment work after the helicopter was deployed into operational condition.

As a result of full-scale testing of the helicopter design, it was possible to achieve that the time to bring the helicopter from the transport position to the operational position by one person was less than 10 minutes.

With a take-off weight of 220 kg. the helicopter lifted a payload of more than 110 kg. with a rotary piston engine power of 40 hp.

The helicopter could cover a distance of up to 150 km at a speed of 110 km/h at flight altitudes of up to 1700 m.

Unfortunately, the helicopter could not be brought to flight tests due to the lack of development of the rotary piston engine and the general lack of a low-power aviation piston engine in our country.

Then new times came and new tasks were assigned to the OKB.

Mini helicopters

Mini helicopters

In addition to building large helicopters, many designers were not at all averse to trying their hand at creating small helicopters for one person. This craze began back in the 50s of the 20th century. It seemed that single-seat helicopters were just about to become as widespread as bicycles and motorcycles. However, it soon became clear that the creators of serial single-seat mini-helicopters had to face a number of problems that had to be solved anew.

These, in particular, included issues of ensuring stability and controllability, combating vibration, and equipping vehicles with capacious and at the same time compact and safe fuel tanks. In a word, the lower the flight weight, the more problems!

Moreover, the “compact cars” themselves also differ significantly from each other in terms of design methodology, structural design, power and type power plant and, of course, for its intended purpose. For example, foreign experts identified devices weighing 130–600 kg as a special “subspecies” for use in sports, military affairs and business travel. Machines weighing 700–1000 kg were supposed to be used for communications, in agriculture, forestries.

Nevertheless, despite the difficulties, many companies still produced small helicopters in limited editions. For example, in the 50s, the New York company Girodain produced the first experimental series of single-seat helicopters of the Rotocycle type with coaxial rotors and a 62 hp engine. With. Initially, "Rotocycles" were supposed to be based on warships to search submarines. In total, the company produced six modifications of manned Rotocycles and one unmanned version. However, they never took root in the navy due to their small range - about 10 miles.

The English company "Hiller" has developed a serial, single-seat "runabout" ROE-1. Packed in a special container, it weighed only 136 kg. If necessary, it could be dropped by parachute. Due to the compactness of such aircraft, they were supposed to be used as a fundamentally new means for rescuing downed pilots.

If the pilot of a downed plane, having descended by parachute, found himself in a place (for example, in a dense jungle), from where a rescue helicopter could not pick him up, it was assumed that “the rescue of a drowning man would be the work of the drowning man himself.” A container with a mini-helicopter was dropped on the pilot. The pilot had to bring the helicopter into working position and fly to the base. Or, at least, he could move to a place where a rescue helicopter could pick him up.

There were ideas to use mini-helicopters instead of traditional parachutes. For example, the US Air Force command intended to use the Kaman folding helicopter KSA-100 during the war with Vietnam.

Testing of the first KSA-100 device began in 1974. When folded, the “helicopter parachute” was attached to the ejection seat. When, as the pilots gloomily joked, “staying in the plane was worse than ejecting,” the pilot and his seat were shot out of the cockpit. After the speed was reduced, the telescopic blades of the main rotor of the “pocket” helicopter extended and the chair turned into a micro-helicopter. Now the pilot could only hope that he would not be shot down a second time and that he would be able to fly 100–120 km to the location of his troops.

...In our country, they tried to use small-sized helicopters on small-scale fishing vessels to search for schools of fish, and on small Arctic coastal vessels for ice reconnaissance. On land, with the help of such machines, they wanted to inspect and repair high-voltage transmission lines, perform aerial photography, seasonal processing of agricultural crops, etc.

For this purpose, the KhAI-27 mini-helicopter was designed at the student design bureau of the Kharkov Aviation Institute named after N. E. Zhukovsky. In 1970 it was demonstrated at the Central Exhibition of Scientific and Technical Creativity of Youth. But before serial production it never came to fruition. In practice, it turned out to be more convenient to use serial light aircraft and helicopters.

However, recently another attempt was made to revive such ultra-light helicopters. Trek Aerospace has released a new aircraft, the Springtail EFV-4! Essentially, it is an Exoskeleton Flying Vehicle (“exoskeleton for flight”), which the pilot puts on himself. After which two helicopter rotors located in ring channels above the pilot’s head were supposed to lift him into the air. The weight of such a device in running order is 270 kg; speed - up to 96.5 km/h; maximum flight altitude - up to 1900 m; range - 100 kilometers; Flight duration is 1.5 hours.

However, due to its bulkiness, this machine will, in all likelihood, remain experimental.

On July 20, 2016, the ultra-light folding helicopter "Mikron" took off for the first time at the Voskresensk airfield. The helicopter on this flight was controlled by Dmitry Rakitsky. That first prototype has already gone to a new owner, and at MAKS 2017 the next version of the helicopter was presented. The design of the device has undergone significant changes; not a single bolt remains from the original version.



manufacturer's website?

Micron is a coaxial helicopter developed by aircraft designer Valery Shokhov, with the support of aviation company AIRLANE and the Gyroplane.ru team. As the creators say, the device was designed based on the Ka-56.

The second Micron has an open cockpit and a propeller with a diameter of 5.3 meters. The light helicopter has high controllability and unique maneuverability. The Micron weighs just 115 kg when empty, is designed for one pilot and features a compact coaxial rotor design.
If I understand correctly, the price for such a helicopter was announced at around 3.5 million rubles?

If I understand correctly, the helicopter blades were created by Nikolai Sannikov (on the forum - niksaan). And a team of composers from Kharkov under the leadership of A.M. Kalnitsky. - prepared fuselage parts from CM.

After the death of Dmitry Rakitsky, the banner of testing these helicopters was picked up by Dmitry Shadrin.

Roller wheels? The wheels on the first copy were larger, what changed?

And it looks like the design of the footrests and pedals is different? I don't see any pedals here at all.

Engine and drive. NV bushing of semi-rigid type with torsion bars from VNS-2. Initially, only four engines were planned for installation on the helicopter: Rotax 503, Hirth H32, MZ 202, RMZ 550, and now R582, RMZ 551.

Dashboard. It’s immediately clear that this helicopter is not going to fly under IFR yet :-)))

Engine MZ202, its weight is 40 kg with a power of 60 hp. .

And belt drive screws.
According to the creators, the specific parameters of the helicopter (load per swept area, load per power) are very close to such devices as the Ka-26 and XRON. Therefore, they expect that the behavior in autorotation mode will not differ much from the behavior of the above-mentioned devices. During the tests, Dmitry Rakitsky, when switching to the autorotation mode, estimated that the time reserve for resetting the speed to a critical value was greater than for the R-22.

Hirobo Electric Corporation promises to launch a revolutionary vehicle - an electric single-seat mini helicopter capable of flying with a passenger at a speed of 100 km/h.

Every now and then no one threatens to make the dream of a car capable of flying or a helicopter that fits in a backpack come true. well-known companies, which quickly disappear without being able to construct anything practical. This time, the serious helicopter manufacturing corporation Hirobo, headquartered in Hiroshima, announced the creation of a compact aircraft. She demonstrated a prototype of this device.

A model of the future mini-helicopter was exhibited at the International Aerospace Exhibition in the Japanese city of Nagoya. According to Hirobo President Kotaro Matsuzaki, his company has invested 10 billion yen ($125 million) to make such vehicles available for personal flights.The main purpose of Hirobo mini-helicopters is transportation during accidents and disasters. The company plans to produce two types of these helicopters: an unmanned one - costing 10 million yen ($125 thousand), and a single-seat one, costing 30 million yen ($375 thousand). Unmanned models can be used for urgent transport of materials such as human organs or blood.

Hirobo mini-helicopters will be able to accelerate to 100 km/h and fly without refueling for 30 minutes. They will be powered by an electric motor, which could make them useful for rescue operations. The quiet sound of the engine will allow the pilot to find people calling for help.Kotaro Matsuzaki plans to release mini-helicopters for sale in 2021 . The company is more concerned about legal rather than technical difficulties. Hirobo predicts it will take two to four years to get approval for mini-helicopters in Japan. The prospect of using mini-helicopters to save people is exciting, but many are concerned about the obvious fact that their use as urban transport poses a significant threat to human life and infrastructure.

Currently on the market you can find gasoline-powered single-seat helicopters costing from several thousand dollars, as well as instructions on how to independently construct such a device based on a chainsaw motor. However, the convenience and safety of these vehicles remain at an extremely low level.

The most famous of the single-seat mini-helicopters is the GEN H-4 produced by the Japanese company Gene. This flying device, costing about $60 thousand, consists of only a seat, a landing gear and two 4-meter propellers rotating in opposite directions. Gasoline engines GEN H-4 are capable of accelerating a helicopter to 90 km/h and work without refueling for 30 minutes.
