In place of the piston aviation aircraft jet comes


By the middle of 1930-ies. it became clear that a further increase in speed of the aircraft at the expense of traditional methods (increasing power of piston engines and improved aerodynamic performance of aircraft) became impossible. By the beginning of World War II, the best military aircraft already had the perfect aerodynamic shape, which has improved virtually impossible. On airplanes were installed engines, which power could already be increased without unduly increasing the mass of the engine. At the end of World War II in the United States of America (the company "Lycoming") was built the largest in the history of aviation piston engine; his power was equal to 5000 l. with. With the increase in power, of course, enormously increased other indicators - weight, size, fuel consumption ... (in this case, one of the advantages overlaps a number of disadvantages). Moreover, to get high speed close to the speed of sound on the piston aircraft impossible. To increase the speed of flight from the fighter to 650 1000 km / h is necessary to increase the capacity of the piston motor in 6 times.

In place of the piston aviation jet aircraft came. It was created and developed by its special way. It was not a simple replacement of the piston engine jet, and the establishment of a single - engine aircraft. Jet engines have advantages over piston in many respects: provide greater power (thrust) per unit weight, the transverse dimensions of the motor is smaller than the piston, can achieve high flight speeds.

World jet aircraft developed in accordance with the general laws of the improvement of equipment - from the simple to the complex, from prototypes to perfect. The history of the evolution of jet aircraft took successively all the stages of its development. When creating new models of aircraft engines and make full use of what has been created before, including related fields of science. It is no accident that the first and best examples of jet aircraft appeared in the countries where the tradition in the field of science and technology have been extremely strong, and the level of aviation industrial

laziness of the previous period is very high (Germany). The greatest success in creating a jet aircraft made scientists and engineers from Germany, Italy, USA, England.

Even in 1938-1940 years. German scientists have developed jet engines Jumo-004A, BM-003A, BMW-028 and "Junkers", they were installed on the aircraft of special design. Flight testing of jet aircraft showed their prospects and the development of such technology. In 1939 in the UK has been designed, built and tested a jet engine Frank Whittle - "Whittle» W-1. Creating the perfect samples of jet engines it was preceded by extensive work of numerous groups of specialists.
