Assembled models of helicopters. Bell Helicopters for Sale About Bell Helicopters

Helicopters of Russia and the world (video, photo, pictures watch online) occupy an important place in the overall system of the national economy and the Armed Forces, honorably fulfilling the civil and military tasks assigned to them. According to the figurative expression of the outstanding Soviet scientist and designer ML. Mile, “our country itself is, as it were, “designed” for helicopters.” Without them, the development of the boundless and impassable spaces of the Far North, Siberia and the Far East is unthinkable. Helicopters have become a familiar element of the landscape of our grandiose construction projects. They are widely used as a vehicle, in agriculture, construction, rescue service, military affairs. When performing a number of operations, helicopters are simply irreplaceable. Who knows how many people's health was saved by the helicopter crews who took part in the aftermath of the Chernobyl accident. The lives of thousands of Soviet soldiers were saved by combat "turntables" in Afghanistan.

Before becoming one of the main modern transport, technological and combat vehicles, Russian helicopters have come a long and not always smooth path of development. The idea of ​​lifting into the air with the help of a main rotor originated among mankind almost earlier than the idea of ​​flying on a fixed wing. In the early stages of the history of aviation and aeronautics, the creation of lift by "screwing into the air" was more popular than other methods. This explains the abundance of rotary-wing aircraft projects in the 19th and early 20th centuries. Only four years separate the flight of the Wright brothers' plane (1903) from the first lift of a man into the air by helicopter (1907).

The best helicopters were used by scientists and inventors, they hesitated for a long time which method to prefer. However, by the end of the first decade of the XX century. less energy-intensive and simpler in terms of aerodynamics, dynamics and strength, the aircraft took the lead. His successes were impressive. Almost 30 years passed before the creators of helicopters finally managed to make their devices workable. Already during the Second World War, helicopters went into mass production and began to be used. After the end of the war, the so-called "helicopter boom" arose. Numerous firms began to build samples of new promising technology, but not all attempts were successful.

Combat helicopters of Russia and the United States It was still more difficult to build than an aircraft of a similar class. Military and civilian customers were in no hurry to put a new type of aviation equipment on a par with the already familiar aircraft. Only the effective use of helicopters by Americans in the early 50s. in the war in Korea convinced a number of military leaders, including Soviet ones, of the advisability of using this aircraft by the armed forces. However, many, as before, continued to consider the helicopter "a temporary delusion of aviation." It took another ten years until helicopters finally proved their exclusivity and indispensability in performing a number of military tasks.

Russian helicopters have played a big role in the creation and development of Russian and Soviet scientists, designers and inventors. Their significance is so great that it even gave rise to one of the founders of the domestic helicopter industry, Academician B.N. Yuriev to consider our state as the "birthplace of helicopters." This statement, of course, is too categorical, but our helicopter pilots have something to be proud of. These are the scientific works of the school of N.E. Zhukovsky in the pre-revolutionary period and the impressive flights of the TsAGI 1-EA helicopter in the pre-war years, the records of the post-war Mi-4, Mi-6, Mi-12, Mi-24 helicopters and the unique Ka family of coaxial helicopters, modern Mi-26 and Ka -32 and much, much more.

The new Russian helicopter is relatively well covered in books and articles. Shortly before his death, B.N. Yuryev began to write the fundamental work "The History of Helicopters", but managed to prepare only the chapters relating to his own work in 1908 - 1914. It should be noted that insufficient attention to the history of such an aviation industry as helicopter construction is also characteristic of foreign researchers.

Military helicopters of Russia in a new way illuminating the history of the development of helicopters and their theories in pre-revolutionary Russia, the contribution of domestic scientists and inventors to the global process of development of this type of equipment. A review of pre-revolutionary domestic works on rotary-wing aircraft, including previously unknown ones, as well as their analysis, were given in the corresponding chapter in the book "Aviation in Russia", prepared for publication in 1988 by TsAGI. However, its small size significantly limited the size of the information provided.

Civil helicopters in their best colors. An attempt has been made to cover the activities of domestic helicopter industry enthusiasts as fully and comprehensively as possible. Therefore, the activities of leading domestic scientists and designers are described, as well as projects and proposals are considered, the authors of which were significantly inferior to them in terms of their knowledge, but whose contribution could not be ignored. Moreover, in some projects, which generally differed in a relatively low level of development, there are also interesting proposals and ideas.

The name of the helicopters denoted significant qualitative changes in this type of equipment. Such events are the beginning of a continuous and systematic development of helicopter projects; the construction of the first full-scale helicopters capable of taking off the ground, and the beginning of mass production and practical use of helicopters. This book chronicles the early history of helicopter engineering, from the concept of propeller lift into the air to the creation of the first helicopters capable of taking off from the ground. A helicopter, unlike an airplane, a flywheel and a rocket, does not have direct prototypes in nature. However, the screw that creates the lifting force of the helicopter has been known since ancient times.

Small Helicopters Despite the fact that propellers were known and there were empirical prototypes of helicopters, the idea of ​​using a main rotor to lift into the air did not become widespread until the end of the 18th century. All the rotorcraft projects being developed at that time remained unknown and were found in the archives many centuries later. As a rule, information about the development of such projects has been preserved in the archives of the most prominent scientists of their time, such as Guo Hong, L. da Vinci, R. Hooke, M.V. Lomonosov, who in 1754 created an "airfield machine".

Private helicopters in a short time were created literally dozens of new designs. It was a competition of the most diverse schemes and forms, as a rule, one- or two-seat apparatus, which had mainly an experimental purpose. The military departments were a natural customer for this expensive and complex equipment. The first helicopters in different countries were assigned to communications and reconnaissance military vehicles. In the development of helicopters, as in many other areas of technology, two lines of development can be clearly distinguished - but the dimensions of the machines, that is, the quantitative one, and the line of development of the qualitative improvement of aircraft within a certain size or weight category that almost simultaneously arose.

Site about helicopters which contains the most complete description. Whether the helicopter is used for geological exploration, agricultural work or for the transport of passengers - the cost of an hour of operation of the helicopter plays a decisive role. A large share of it is depreciation, that is, the price divided by its service life. The latter is determined by the resource of the aggregates, r, e. by their service life. The problem of increasing the fatigue strength of blades, shafts and transmissions, main rotor bushings and other helicopter units has become a paramount task that still occupies helicopter designers. Nowadays, a resource of 1000 hours is no longer a rarity for a serial helicopter, and there is no reason to doubt its further increase.

Modern helicopters comparing the combat capabilities of the original video has been preserved. The image found in some publications is an approximate reconstruction, and not entirely indisputable, carried out in 1947 by N.I. Kamov. However, a number of conclusions can be drawn on the basis of the archival documents cited. Judging by the test method (suspension on blocks), the “airfield machine” was undoubtedly a vertical take-off and landing apparatus. Of the two methods of vertical lift known at that time - with the help of flapping wings or by means of a main rotor - the first seems unlikely. The protocol says that the wings moved horizontally. In most flyers, they are known to move in a vertical plane. A flywheel whose wings oscillate in a horizontal plane with an installation angle that changes cyclically, despite repeated attempts, has not yet been built.

The best helicopter design is always directed to the future. However, in order to more clearly imagine the possibilities for further development of helicopters, it is useful to try to understand the main directions of their development from past experience. What is interesting here, of course, is not the prehistory of helicopter construction, which we will only briefly mention, but its history from the moment when the helicopter, as a new type of aircraft, was already suitable for practical use. The first mention of a device with a vertical propeller - a helicopter, is contained in the notes of Leonardo da Vinci dating back to 1483. The first stage of development stretches from the model of a helicopter created by M. V. Lomonosov in 1754, through a long series of projects, models, and even devices built in kind , which were not destined to take to the air, until the construction of the world's first helicopter, which in 1907 managed to get off the ground.

The fastest helicopter in the outlines of this machine, we recognize the schematic diagram of the most common single-rotor helicopters in the world now. B. I. Yuryev managed to return to this work only in 1925. In 1932, a group of engineers, headed by A. M. Cheremukhitsnch, built a TsAGI 1-EA helicopter, which reached a flight altitude of 600 m and lasted 18 m / w in the air which was an outstanding achievement for that time. Suffice it to say that the official flight altitude record, set 3 years later on the new Breguet coaxial helicopter, was only 180 m. At this time, there was a pause in the development of helicopters (helicopters). A new branch of rotorcraft, gyroplanes, came to the fore.

The new Russian helicopter, with a greater load on the wing area, came face to face with the then new spin problem of loss of speed. It turned out to be easier to create a safe and sufficiently perfect autogyro than to build a helicopter helicopter. The main rotor, freely rotating from the oncoming flow, eliminated the need for complex gearboxes and transmissions. The articulated attachment of the main rotor blades to the hub used on gyroplanes provided them with much greater strength, and stability for the gyroplane. Finally, stopping the engine was no longer dangerous, as was the case with the first helicopters: by autorotating the gyroplane, it was easy to land at low speed.

Large helicopters for landing marines from ships determined the further development of the military helicopter industry as a transport and landing. The landing by S-55 helicopters of the American troops at Inchon during the Korean War (1951) confirmed this trend. The size range of transport and assault helicopters began to be determined by the dimensions and weight of ground vehicles used by the troops and which had to be airlifted. Therefore, the carrying capacity of the first transport helicopters in foreign armies was 1200-1600 kg (the weight of a light military vehicle used as a tractor and related guns).

USSR helicopters correspond to the weight of light and medium tanks or corresponding self-propelled chassis. Whether this line of development will be completed in such a range of dimensions depends on the ever-changing military doctrine. Artillery systems are mostly being replaced by missiles, which is why we also find demands from the foreign press. Power did not lead to an increase in payload. Indeed, but to the technical level of that time, the weight of propellers, gearboxes for the entire apparatus as a whole increased with an increase in power faster than the lifting force increased. However, when creating a new useful and even more so new for national economic application, the designer cannot put up with a decrease in the achieved level of weight return.

Soviet helicopters, the first samples, were created in a relatively short time, since the specific gravity of piston engines always decreased with increasing power. But in 1953, after the creation of the 13-ton Sikorsky S-56 helicopter with two 2300-hp piston engines. with the size range of helicopters in the Zapal was interrupted and only in the USSR, using turboprop engines. In the mid-fifties, the reliability of helicopters became much higher, therefore, the possibilities of their use in the national economy also expanded. Economic issues came to the fore.

Since the advent of helicopters, the scope of their operation has become very extensive.

And aircraft lovers will surely be interested to look at these

Plastic rotorcraft will decorate your office or room with just a little effort and a couple of evenings. The prefabricated helicopter model will look perfect if it is not installed on a stand, but suspended on a special system from the ceiling. A helicopter, like a butterfly, is much more beautiful in flight than on the ground.

What are helicopters

For most people, the concept of helicopters begins and ends with the MI 8 model. Yes, this is the most popular helicopter brand in the world. The more advanced MI 24 and MI 26 also developed from him.

But how many people know that the largest and most lifting helicopter in the world was designed and built in the Soviet Union?
This is an MI 10 record holder. The records that he set have been holding for half a century, and an objective look at the helicopter industry allows us to assume with great confidence that this achievement will not be surpassed very soon.

For such giants, 1/144 scale is used. Most of the other models are produced in the popular 1/35 scale.

Finishing

The assembled model, regardless of the material, must be covered with paint and pasted over with decals. Only in this form, a composite copy of the helicopter will serve as the personification of the power of domestic science and technology.

The finished product is best hung on a special fixture to the ceiling. After all, a helicopter is designed to fly, no matter what size it is.

In "HeliCo Group" you can buy helicopters of the American company Bell Helicopters. The cars of this manufacturer are actively used by the military, special services, civilian carriers, rescuers, and individuals.

The range of the most popular and successful models:

• Bell 206-B3. A light universal rotorcraft has been produced since the middle of the 20th century. It is actively used by businessmen, police, transport companies, rescuers and doctors. There are military versions of the 206-B3.
• Bell 407 and 407GX. Light helicopter with one engine. The car is suitable for transport companies, special services, VIP transportation. Modification 407GX is equipped with a unique control system that improves flight safety in extreme conditions. The famous Bell ARH-70 attack helicopter was created on the basis of the Bell 407.

Benefits of Bell Helicopters

Bell Helicopters has been operating since the 1930s. Over the decades, the manufacturer has produced tens of thousands of civilian and military vehicles.

The Bell UH-1 Iroquois helicopter is the most massive model in the history of the world helicopter industry.

The distinctive characteristics of Bell helicopters are:

• Machine reliability. In the course of mass production of popular models, Bell Helicopters takes into account and eliminates any shortcomings identified during operation. Most civilian Bell vehicles have military modifications that are tested in extreme conditions.
• Accurate and reliable navigation systems. The American manufacturer creates helicopters that can be used in remote areas without the risk of going astray.
• Possibility of modification for performance of special tasks. At your request, the manufacturer equips the machine with additional equipment. The same model can act as a helicopter for a private person with a VIP interior, a rescue or medical board, a police vessel.

About Bell Helicopters

Bell Helicopters is a division of Textron Corporation. The company has factories in the US and Canada. It specializes in the production of civil and military helicopters. Bell's assets include the development and production of the V-22 Osprey tiltrotor. This machine - a hybrid of a helicopter and an airplane - is in service with the US Air Force.

USA, Japan, Taiwan, Germany and Italy

Type: utility and close support helicopter

Capacity: pilot and up to 14 passengers (modification UH-1H)

The Bell UH-1 family of helicopters, built since the end of World War II in greater numbers than any other military aircraft, have been operated by the air forces of various countries more than other types. Based on the prototype XH-40, which was built by Bell in response to the US Army's need for utility helicopters and casualty evacuation. The first serial helicopter HU-1A, which he received later, entered service in the late 1950s. In 1961, the Bell company finalized the design and created the Model 205 helicopter, using a longer fuselage and a powerful engine.

As a result, the UH-1D / H helicopters became the most popular among the military - they remained in production until 1986. Only 2008 modification D helicopters were delivered to the US Army alone. The basis of airmobile units in the Vietnam War - the Iroquois helicopter (Iroquois) during the war was also armed with various machine guns, both fixed in hanging containers and manually controlled uncontrolled, and was also used in the role of a helicopter artillery battery.

Further modifications included helicopters equipped with two engines for naval forces, anti-submarine radar for sea search, and a very enlarged helicopter to transport 17 soldiers - the original UH-1A could only accommodate six. Still widely used today, the Bell UH-1 helicopter in its many modifications will undoubtedly play an important role in the armed forces in the 21st century. A large number of Iroquois helicopters released from military service were sold to private customers, mainly in the United States, where they perform a wide variety of work.

The equipment that is primarily associated with the Vietnam War is the American Bell UH-1 Iroquois helicopter (Iroquois). At one time, helicopters performed very well in Korea. This forced the American command to pay special attention to them.

In the early 50s, a competition was held to create a light multi-purpose helicopter with the ability to install machine guns and missiles. In 1955, the project of the Bell Helicopter Company was recognized as the best option.

The first prototype (Model 204) was powered by a Lycoming T53 turboshaft engine. The first flight of the prototype took place on October 20, 1956 in Fort Worth (Texas). The army version was designated as HU-1 Iroquois (later UH-1). The UH-1A helicopters with the Lycoming T53-L-1A engine (770 hp) went into mass production.

Lycoming T53 engine

The Bell UH-1 Iroquois is a classic single-rotor helicopter with a two-blade main rotor and a two-blade tail rotor. The fuselage structure is semi-monocoque, consisting of a two-seat cockpit, cargo compartment and tail boom. The functions of the landing device are performed by steel skis. The power plant is located in the upper part of the fuselage and consists of one or two engines, depending on the modification of the helicopter. The fuel system consists of two tanks (625 liters), which are located behind the cockpit. The helicopter can carry machine-gun and missile weapons.

Over time, new modifications of this machine appeared. In 1961, the UH-1B began to enter the army, on which the T53-L-5 engine (960 hp) was installed. In 1963, the US Marine Corps received UH-1E helicopters, which were equipped with more modern radio equipment. In 1965, a new modification of the machine, the UH-1C, appeared, which was distinguished by an improved design of the main rotor. The UH-1D was distinguished by a new fuselage design, which made it possible to increase the volume of the cargo compartment. Since 1965, attempts have been made to install two engines on the UH-1. The result was a modification of the UH-1N with two Pratt & Whitney PT6T-3 engines (with a total power of 1800 hp). "Iroquois" is one of the most massive helicopters in the history of American aviation, more than 8000 units were built in total. The machine was exported and produced under license abroad.
