Yakovlev Yak-60

Project of a heavy military transport helicopter Yakovlev Yak-60 ( Yakovlev Yak-60).

The beginnings of OKB Alexander Sergeyevich Yakovlev ( А. С. Яковлев) date back to the second half of the 1920s, when a small group of enthusiasts formed around him, with whom he built his first light aircraft AIR-1. . The date of flight of this machine - May 12, 1927 - is considered the date of creation of KB, although the order of government authorities on its official creation has a later date. In line with his ideas about people's aviation, Yakovlev focuses on light sports and training aircraft. During World War II, he was one of the creators of light fighter jets and light bombers. Yakovlev's OKB also managed the advent of jet propulsion, although OKB MiG Mikoyan and Gurevich were eventually pushed out of the leadership position. Throughout the existence of OKB Jakovleva, more than 200 different types and modifications of flying machines were created here, among which there were more than 100 mass-produced machines. This KB's aircraft have been in continuous production since 1932, and in more than 70 years the number of aircraft produced has exceeded 70,000. .

Already at the end of the war - since 1944 - the attention of his OKB turned to this somewhat exotic flying apparatus. Yakovlev joined his team of capable "helicopters" Sergei Arsentevich Bemov ( Сергей Арсентевич Бемов), and Igor Alexandrovič Erlich ( Игорчилел The first serious construction of his OKB will be a machine, originally called EG - Type Š ( Экспериментальный Геликоптер - ЭГ- изделие Ш). This machine of the coaxial concept, ie with counter-rotating propellers on a common axis and without a compensating tail propeller, will be flown after a long development - 1945 - 1948, but will not go into serial production. In the interest of OKB, its next project will be - helicopter Jak-100, which with its concept of the main propeller and balancing tail propeller will be the management of VVS and the government - namely JV Stalin - less exotic. In addition, it will be very similar to the successful construction Sikorsky H-5, which successfully served in the US Army. S. A. Bemov will have the main credit for the construction of both types. The machine will also be successfully flown, but he will not go into series production either. There he is overtaken by his "competitor" helicopter Mil Mi-1.

Only the third construction, the helicopter Yakovlev Yak-24, nicknamed "Flying Wagon", the work of I. A. Erlich, will undergo serial production and a number of modifications.

The success of the Jak-24 type will bring designers to the idea of building an even more powerful machine, created according to this scheme. Thus arose the project of a heavy military transport helicopter Jak-60, which, in terms of payload, could compete with many military transport aircraft.

The new helicopter received the designation Jak-60, and was to become a companion to the largest helicopter in the world, which was designed at the same time in KB Mil (it is a helicopter V-12). The takeoff weight of the Jak-60 was to be about 100 tons. The rotors were taken from the helicopter Mi-6, each of which was powered by two D-25VF engines. In accordance with the project, the helicopter was able to lift cargo weighing up to 42 tons. Such a carrying capacity allows the use of a helicopter on the outer suspension to transport a tank, for example T-64. However, unlike Milo's helicopter, the Jak-60 remained forever just a project that did not rise to the sky. Only a certain number of models of this helicopter were produced.

Work on the Jak-60 project was carried out by the Leningrad branch of OKB-115 at MAP No. 272 under the direct leadership of chief designer Igor Alexandrovich Erlich.The experience of development and operation of the predecessor - Jak-24 was taken into account in its design. The project of a new heavy helicopter with rotors in a row, equipped with 4 engines, began to develop on the basis of a resolution of the Council of Ministers of the USSR from February 1958. The helicopter was to use four powerful gas turbine engines D-25VF, giving 6497 hp each. The external dimensions of the giant helicopter from OKB Jakovlev were as follows: length - 44.6 m, width - 8.6 m, height - 11.6 m.

Such dimensions and carrying capacity at the level of 40 tons opened up great opportunities in front of the helicopter both in the military air force and in the civilian sector. The 50's and 60's are marked by great "buildings of socialism" in the USSR, and modern heavy machinery could be well applied to them. The purpose of this gigantic helicopter was the air movement of bulk and material loads: tanks, self-propelled guns, armored vehicles, ballistic missiles, ground RLS, bridge girders, pontoon blocks, drilling rigs, power transmission poles, river boats, ammunition and other armaments, and other various very heavy costs of economic determination.

In addition to the cargo cabin space, the Jak-60 could carry cargo on the outer suspension. The helicopter could take on board up to 228 paratrooper soldiers in full combat gear or 176 wounded accompanied by 8 medical personnel. However, the work on the helicopter did not leave the design phase I of the technical project. The main reason was the diversion of OKB-115 from the helicopter issue, as well as the closure of its Leningrad branch with the subsequent removal of plant No. 272. However, a similar giant in the USSR was still created. It is a helicopter V-12 KB Mila (sometimes called Mi-12, although it never bore such a designation). Identical D-25VF engines were used on V-12. Mil's V-12 first took off in 1968 and the machine remains the largest helicopter with the largest load capacity in the world. Mil's giant also remained a solitary structure, the Soviet economy could not cope with its use, despite loud propaganda.
