A new book from the bestselling author of “Cars of the Red Army” and “Military Vehicles of the Wehrmacht.” A unique encyclopedia of vehicles in service with the Soviet Army in 1945–1991. Complete information about all types of serial army vehicles, special bodies, superstructures and weapons, as well as first-generation armored personnel carriers produced on army truck chassis.

If during the Second World War the USSR was catastrophically behind the West in the quality and quantity of vehicles, which became one of the main reasons for the defeats of 1941–1942, then after the Victory our military automobile industry made a colossal leap, not only catching up, but in some ways (for example , in the production of mobile wheeled missile weapon systems and ferry vehicles) even surpassing the “probable enemy”. The best Soviet army vehicles - the legendary GAZ-69, UAZ-469, GAZ-66, ZIL-157, ZIL-131 and Ural-375 - rightfully occupied high positions in world rankings, distinguished by their simplicity, reliability and excellent cross-country ability. Era 1950–1960s became truly a “finest hour” for the entire domestic military-industrial complex, including the automotive industry, which was capable of independently developing unique military equipment that had no analogues abroad, and producing the best all-wheel drive army vehicles with special equipment and weapons in the entire Russian history. This fierce “war of engines,” in which parity with NATO was achieved and the country’s real security was ensured, is described in a new book by a leading specialist in the history of the automotive industry, illustrated with hundreds of rare photographs.

With the start of production of the GAZ-66 truck, slightly modernized chemical equipment, developed for the GAZ-51, GAZ-63 and ZIL-164, was installed on its chassis. This included a modified compact steam elevator disinfection and shower unit DDA-53B, and Komarov’s multi-purpose disinfection installation DUK-1, which by that time was based on the GAZ-52 chassis, was simultaneously mounted on the GAZ-66. In April 1962, a disinfection shower unit was put into service DDA-2 on the GAZ-66 chassis for military sanitary and epidemiological units and civil defense units, previously developed for the ZIL-164 truck. Its modernized, more compact version DDA-3 for GAZ-66 it was distinguished by the volume of disinfection chambers reduced to 2.4 m 3. The modernized smoke machine was based on the 66th chassis TDA-M, originally created for the GAZ-63, as well as the radiation-chemical workshop PRHM-1M. In the second half of the 1960s, by refining the DDA-53B model, the most advanced and widespread DDA-66 station was created, which became a “classic” among machines for this purpose.

TDA-M machine for setting up smoke screens by evaporating a special mixture.

DDA-66/66P– effective disinfection and shower units on the GAZ-66 chassis. The first version of the DDA-66 on the GAZ-66-01 vehicle was put into service in August 1968, the second modernized DDA-66P was mounted on the 66-11 chassis. They were manufactured by the Perm Avtomedtekhnika plant. The installations were widely used in military sanitary and epidemiological units and in Civil Defense units. They served for disinfection and disinfestation of clothing, shoes, linen and bedding using steam-formalin and steam-air methods, as well as for washing people in the field at any time of the year. Their equipment was housed in a special rectangular welded all-metal body with rear hinged panels and three compartments - a boiler room with a steam boiler and a boiler, a compartment with a disinfection chamber and a cargo-passenger room for personnel. People were washed with heated water through shower nets in tents or in the open air. The throughput capacity under favorable weather conditions reached 48 people per hour. The total weight of the units is 6080 kg. Preparation time for work in summer is 30 minutes, in winter – 1 hour. The DDA-66P installation was based in parallel on the ZIL-130 chassis.

The DDA-100 M double-cantilever sprinkler unit is mounted on a DT-75 tractor and is a short-spray type unit. Consists of a two-cantilever truss and a pumping unit. The cross section of the truss has the shape of an equilateral triangle. The lower belt of the truss is made of a pipe through which water is supplied. Tubular flaps are welded to the water supply pipe, at the ends of which 52 deflector nozzles are installed. Two jet nozzles with deflector blades are mounted at the ends of the truss. The unit is equipped with a hydraulic system to regulate the tilt of the farm. The farm rests on a turntable, which allows it to be rotated into a transport position along the tractor.

The pumping unit takes water from the irrigation canal and delivers it under pressure into the farm’s water supply pipe. The float type suction device can be raised and lowered from the driver's cab using a lift mounted on the tractor. The depth of water in the irrigation channel during its intake must be at least 25-30 cm. The unit operates in motion with surface slopes of up to 0.005. Irrigation canals are made permanent or temporary.

Water is supplied to sprinklers from main or distribution channels through automatic or manual water inlets, as well as from pipelines through hydrants.

15. Movement of Liquids, the law of liquid movement in open watercourses. Bernoulli equation.

According to the nature of the speed and flow rate, the movement of water can be steady and unsteady. A set motion is a movement in which the speed and flow rate of water, and therefore the pressure at all points of the flow, are constant over the period of time under consideration. Such movement is observed in rivers when the water level remains unchanged or, when water flows out of a reservoir, when the free surface level remains unchanged.

Unstable movement is a movement in which the speed and flow of water within the period under consideration changes, for example, in a river when levels change (during a flood, during

time of water discharge through spillway structures at dams). Based on the nature of flow movement along the length of a watercourse, steady-state movement is divided into uniform and uneven.

Water movement is uniform when the shape and cross-sectional area of ​​the channel, as well as the average speeds and velocities at all points along the length of the flow are the same.

Uneven movement is variable

flow cross-sectional areas, depths, flow velocities along the length. This textbook discusses calculations for uniform motion.

According to the nature of the regime, water movement is divided into laminar

and turbulent. The laminar mode of motion is characterized by

moving water without mixing the jets (mainly

when groundwater or water moves in thin capillary

tubes Turbulent mode is characterized by mixing

particles of water, which, in addition to translational motion at high speeds, also have rotational motion. This regime is observed in pipes, rivers, canals, etc.

According to the nature of the forces causing fluid movement, it can

be pressure and non-pressure. PRESSURE-FREE MOVEMENT -

n i e occurs under the influence of 1\"1 gravity forces. Flow surface__

not limited, located under atmospheric pressure. This kind

movement is observed in rivers, canals, pipes when they are incomplete

filling. Pressure movement occurs under the influence

pressure (pressure) created by pumps, water tower

or when supplying water through pipes from ponds located above

consumers (for example, Peterhof fountains), etc. Movement

water is characterized by the Bernoulli equation:

where Z\ and Z:, - geometric height of the centers of gravity of the flow in sections

1-II (Fig. 5); P, uP:, - hydrostatic pressure; y - specific

mass of water; V, and V2 - speed of water movement; a - correction

coefficient for the average flow rate (equal to 1.1 on average);

P/U and P/U - piezometric pressure height in sections 1-11;

Z,+ P/U and Z2+ P/U - piezometric pressure characterizing

specific potential energy in sections I-II; V//2g and V-//2gspeed

pressure characterizing specific kinetic energy

in sections 1 and 11; 11ш - loss of pressure or specific energy. All

quantities have the dimension of speed.

2) The impact of drainage of forest lands on the water regime of surrounding areas . The construction of a reclamation (drainage or drainage-humidification) system changes the direction and intensity of natural processes in the soil and ground layer of the atmosphere, the distribution of water resources, as a result of which the entire ecosystem of the region acquires new properties. The reclamation system affects the environment directly and indirectly. The direct impact is the removal of excess water and the creation of conditions for intensive agricultural farming on reclaimed lands. Indirect impact is, as a rule, an impact on some environmental factors at the site itself, as well as on adjacent lands, that is not foreseen by the project. Positive indirect effects are associated with the replacement of the plant community with non-reclaimed ones. The negative indirect impact usually covers a large number of factors, manifests itself over a long period of time and often turns out to be unexpected. Of the entire complex of factors undergoing changes, first of all, the following are distinguished: flow rate and water levels in watercourses; volume of surface and underground water reserves in the region; levels groundwater at the site and adjacent lands; volume and nature of evaporation from the water surface and soil; temperature regime of the soil; progress and possible change in the direction of the soil-forming process; change in flora and fauna of the region. Drainage of swamps and wetlands is inevitably associated with a decrease in groundwater levels at the site and redistribution of water volumes. In this regard, the root causes of changes in the environment are changes in the level regime of groundwater and surface runoff, as well as changes in vegetation as a result of cultural work and planning. Under the influence of drainage, first of all, the degree of drainage of the drainage basin increases. Under natural conditions, the drainage capacity of swampy catchment areas with a swamp area of ​​20-30% of the basin area is usually less than 1 km/km2. The consequence of increasing drainage is, on the one hand, an increase in the speed at which snow and rainwater reaches the river, which contributes to an increase in water flow in the river. On the other hand, artificial drainage of the territory causes a decrease in the groundwater level, as well as an increase in the thickness of the aeration zone (soil layer with incomplete saturation with moisture). A decrease in groundwater levels leads to an increase in groundwater slopes in the adjacent territory and pressure water gradients, which causes an increase in the underground component of river flow, especially in the first years after drainage. Under the influence of drainage, peat sediments, and the surface of the swamp changes: its slopes towards channels and deep drains increase, which promotes surface runoff. After drainage, evaporation conditions change. Lower groundwater levels cause

reduction of evaporation from the soil surface, but this indicator is not the main one. During agricultural use of the territory, wild moisture-loving vegetation is replaced by crops, which causes a change in transpiration, and therefore total evaporation. Drainage of soils, especially peat ones, significantly changes their temperature regime. This is due to the fact that with a decrease in the humidity and density of peat, the ratio between its solid, liquid and gaseous phases changes more sharply than on mineral soils. The influence of drainage systems on the landscapes of the adjacent territory From the point of view of a physical geographer, drainage is the destruction of hydromorphic complexes, forest and shrub vegetation, the leveling of local natural differences through cultural work, liming, and the application of mineral and organic fertilizers. This leads to the formation of an anthropogenic landscape with its inherent processes of reclamation erosion, deflation, mineralization and depletion of peat deposits, soil compaction and complete restructuring of the avifauna. At the same time, new properties of the landscape appear: an increase in fire danger on peatlands, a decrease in the duration of the frost-free period and a decrease in soil and air temperatures at night, a reduction and even the disappearance of some types of natural fauna. The influence of drainage occurs through the moving components of the landscape - surface (drainage runoff) and groundwater. Three areas of influence can be traced: two – direct (hydrological and hydrogeological); the third is agrotechnical and other human activities. The hydrological influence has been studied in sufficient detail, especially using the example of Polesie (Bulavko, Maslov, 1975; Shebeko, 1978; etc.), and boils down to the following. Drainage contributes to an increase in annual runoff within the accuracy of hydrometric studies (up to 15%), reliably in the first years, due to the use of “centuries-old” reserves of swamp and groundwater. During the period of intensive plant growing, runoff decreases, especially with optimal use of drained lands (Novikov, 1980). The maximum spring flow increases, but the maximum low-provision flow decreases. The minimum flow after drainage increases by 1.7-3.8 times, and the summer low-water flow also increases. In general, the intra-annual distribution of flow becomes more uniform. The size of the zone of hydrogeological influence is determined by: the depth of drainage, the distance between the drains of the regulating and conducting networks, the type of regulation, the lithological composition of rocks, the thickness of the aquifer, relief slopes, seasonal weather conditions, and the properties of geocomplexes in the adjacent territory.
