🔆 In 1970, an experimental jet train- high-speed laboratory car (SVL). It should be noted that in the Soviet Union the use of jet aircraft engines in transport was given great importance.
The body of the high-speed car was built on the basis of the ER22 motor lead car, which was supplied with head and tail fairings, and undercar equipment and chassis closed on both sides with removable bulwarks. On the roof of this train was equipped with a turbo jet engines AI-25 used on the Yak-40 passenger aircraft.
The length of the car is 28 m. The weight is 59.4 tons (including fuel - 7.2 tons). The maximum speed achieved during the tests is 250 km / h.
The reason for the creation of such a locomotive unusual type there were ideas for organizing high-speed rail communication and the further use of AI-25 aircraft engines, which had exhausted their aviation resources, but were still suitable for further operation “on the ground”.
From 1971 to 1975, the SVL high-speed laboratory car was used for experimental trips and research work.
It should be noted that the purpose of the tests was not to set a speed record. The tests were carried out to study the interactions in the "wheel-rail" system for future high-speed trains. For testing, the car “that rides by itself” was best suited, without repelling the wheels from the rails. It was not possible to attach a wagon to a locomotive, because in 1970 there were no locomotives in the USSR capable of maintaining a speed of more than 230 km / h for a long time. railway track, also did not allow speeds of more than 250 km / h.
In 1975, after the launch of the ER200 (Soviet high-speed electric train direct current) the need for SVL with its voracious and demanding great attention jet engines disappeared, and single copy SVL was abandoned on the territory of the Kazan Helicopter Plant.
In the period 1999-2003. the option of transferring the SVL to the museum of railway equipment in St. Petersburg was considered, but the issue of distillation of the car was not resolved. The pneumochambers of the bogies “sunk”, and according to the state of the running gear, the speed of transporting the car could not exceed 25 km / h. As a result, the car remained in the same place. At present, a stele has been made from the front of the car in front of the KVZ entrance.
In the Union, the use of jet aircraft engines in transport sector attached great importance. In 1970, the Kalinin Carriage Works completed the manufacture of a jet locomotive, called the SVL (high-speed laboratory car).
The body of the high-speed car was built on the basis of the ER22 motor lead car, which has head and tail fairings, and undercar equipment and undercarriage are closed on both sides with removable bulwarks.
Moreover, the cabin, frontal and rear walls of the ER22 are preserved, the fairings are only "nozzles". It's funny that as a result, the driver looks at the way through two windows: the cab and the fairing.
The shape of the fairings is a development of Moscow State University and has a coefficient drag 0.252. The car model was blown into wind tunnel TsAGI.
As a matter of fact, Kazan Helicopter Plant planned to build a high-speed jet train "Russian Troika" with these fairings. For decreasing air resistance when moving to high speeds the SA-3 automatic coupler is also closed with a removable fairing.
The head car ER22-67 was specially built by the Riga Carriage Works for the SVL - that is, the drawings were ordinary, but Special attention focused on manufacturing quality. Initially, the SVL was painted in the colors of ER22: cream-yellow top and red bottom. The length of the car with fairings is 28 m.
The car has two-axle bogies, unusual for the head car, designed by the Kalinin Carriage Works and VNIIV with central suspension pneumatic springs. Such bogies were previously rolled under trailer cars of ER22 electric trains.
The car is equipped disc brakes with pneumatic and electro-pneumatic control. There are sandboxes to increase the adhesion of the wheels to the rails when braking. On the roof of the car in its head part on a special pylon, two aviation turbojet engine Yak-40 aircraft, which create the necessary traction force for the movement of the car. The weight of two engines is less than 1 ton. Their maximum traction force is 3000 kgf.
The driver's cab is equipped with an aircraft engine control panel, as well as conventional brake and sandbox controls. A diesel generator was installed in the car body. The compressor motor is powered by the generator. lighting, control circuits and electric furnaces. The car in the equipped state weighed 59.4 tons, including fuel (kerosene) 7.2 tons.
In 1971, an experimental car was tested on the line Golutvin - Ozyory of the Moscow Road, where a speed of 187 km / h was reached. Then, at the beginning of 1972, the car made trips on the section Novomoskovsk - Dneprodzerzhinsk Pridneprovskaya railway, where it gradually increased maximum speed(160, 180, 200 km/h). The result of the tests was a speed of 249 km / h.
It should be noted that the goal was not to set a speed record. The tests were carried out to study interactions in the "wheel-rail" system for future high-speed trains. For testing, the car “that rides by itself” was best suited, without repelling the wheels from the rails.
