Developed from the Ivchenko AI-25 turbofan engine, ZVL
82-607: A Viking voyage to eastern Europe. The River Dnieper has been a subject for artists, great and minor, over the centuries. Major artists with works based on the Dnieper are Arkhip Kuindzhi and Ivan Aivazovsky . The River Dnieper makes an appearance in the 1964 Hungarian drama film The Sons of the Stone-Hearted Man (based on the novel of the same name by Mór Jókai ), where it appears when two characters are leaving Saint Petersburg but get attacked by wolves. In 1983,
123-570: A large-scale reconstruction of the canal. A 23 km (14 mi) long stretch of the canal was built near Kobrin to straighten the old canal. Eight locks were built replacing movable weirs . Navigation on the Dnieper–Bug Canal is interrupted by weirs on the rivers Mukhavets and Bug near Brest, Belarus , the border town. That is the only place that, for the time being, makes the navigation from Western Europe to Belarus and Ukraine through inland waterways impossible. The waterways from
164-537: A result, the canal became navigable for bigger vessels, in particular steamers , at any time from spring till autumn. In 1847, the Kanał Królewski was renamed the Dneprovo-Bugski Canal . After the construction of the railway along the canal in the late 19th century the canal was used mostly for rafting lumber , exported to western countries. During World War I, the canal was not in use. During

The total length of the river is variously given as 2,145 kilometres (1,333 mi) or 2,201 km (1,368 mi), of which 485 km (301 mi) are within Russia, 700 km (430 mi) are within Belarus , and 1,095 km (680 mi) are within Ukraine . Its basin covers 504,000 square kilometres (195,000 sq mi), of which 289,000 km (112,000 sq mi) are within Ukraine, 118,360 km (45,700 sq mi) are within Belarus. The source of

The Middle Ukrainian form attested in the sixteenth to eighteenth centuries was Днѣпръ , Dnǐpr . The city of Dnipro is named for the river. The name varies slightly in the local Slavic languages of the three countries through which it flows: These names are all cognate, deriving from Old East Slavic Дънѣпръ ( Dŭněprŭ ). The origin of this name

Almost 2,000 km (1,200 mi) of the river is navigable (to the city of Dorogobuzh ). The Dnieper is important for transportation in the economy of Ukraine . Its reservoirs have large ship locks, allowing vessels of up to 270 by 18 metres (886 ft × 59 ft) access as far as
328-622: Is disputed but generally derived from either Sarmatian * Dānu Apara ("Farther River") in parallel with the Dniester ("Nearer River") or from Scythian * Dānu Apr ("Deep River") in reference to its lack of fords , from which was also derived the Late Antique name of the river, Δάναπρις Danapris , as found in the Ravenna Cosmography . The earlier Graeco-Roman name of the river, as attested by Herodotus ,
369-639: Is due to the influence of the Old East Slavic epic The Tale of Igor's Campaign and its modern adaptations on Ukrainian literature. This usage also lent its name to the city of Slavutych , founded in the wake of the Chernobyl disaster in 1986 to house displaced workers, and to the Slavutych station of the Kyiv Metro . In Crimean Tatar , the river is known as Özü . In Turkish it

#1732800807460492-475: The Polish–Lithuanian Commonwealth was the first to suggest the idea of upgrading the portage to a canal with locks. The work started 120 years later. In 1770, the canal was planned by the prominent cartographer Franciszek Florian Czaki . The canal was built in 1775-1784 during the reign of Stanisław August Poniatowski , the last king of the Polish–Lithuanian Commonwealth . Originally it

The Kakhovka dam was destroyed on 6 June 2023 during the Russian invasion of Ukraine , with the subsequent drying up of the Kakhovka Reservoir revealing the original course of the river in the area and disconnecting four canal networks known as
574-511: The Pripyat River , a tributary of the Dnieper, just upstream from its confluence with the Dnieper. The Dnieper is an important navigable waterway for the economy of Ukraine and is connected by the Dnieper–Bug Canal to other waterways in Europe. During the 2022 Russian invasion of Ukraine , certain segments of the river were made part of the defensive lines between territory controlled by

Approximately 2,200 km (1,400 mi) long, with a drainage basin of 504,000 square kilometres (195,000 sq mi), it is the longest river of Ukraine and Belarus and the fourth- longest river in Europe , after the Volga , Danube , and Ural rivers. In antiquity, the river

The Flotilla was the inland branch of the Polish Navy operating in the area of the Pinsk Marshes between the Polish-Bolshevik War and World War II . During the 1920s, two locks were built. In 1940, the Soviet authorities initiated
697-711: The Dnieper is the sedge bogs (Akseninsky Mokh) of the Valdai Hills in central Russia, at an elevation of 220 m (720 ft). For 115 km (71 mi) of its length, it serves as the border between Belarus and Ukraine. Its estuary, or liman , used to be defended by the strong fortress of Ochakiv . The southernmost point in Belarus is on the Dnieper to the south of Kamaryn in Brahin Raion . The Dnieper has many tributaries (up to 32,000) with 89 being rivers of 100+ km. The main ones are, from its source to its mouth , with left (L) or right (R) bank indicated: Many small direct tributaries also exist, such as, in

Poor political relations between Western Europe and Belarus mean there is little likelihood of reopening this waterway in the near future. River navigation is interrupted each year by freezing and severe winter storms. From the mouth of
984-444: The canal system totals 8,500 km (3,300 sq mi). Canal building flourished in the Polish–Lithuanian Commonwealth in the late 18th century. Yet many of the early canals are no longer in active service, having been superseded by railroads and highways. The Dnieper–Bug Canal after several enlargements still provides a convenient inland waterway. Until the 18th century there was a portage between Kobrin and Pinsk as it

Virsky Ukrainian National Folk Dance Ensemble , Kyiv Bandurist Capella ,
1066-450: The most unusual features of this military engine is the single stage fan; most trainer and combat engines have multi-staged fans, single stage fans normally being the preserve of civil and military transport turbofans. Ivchenko Lotarev chose a very low specific thrust (net thrust/airflow) cycle for the DV-2, so a single stage fan is sufficient to develop the desired fan pressure ratio. Even so,

More recently efforts have been undertaken to restore the canal to a class IV inland waterway of international importance. In 2003 the Government of the Republic of Belarus adopted an inland water transport and sea transport development program to rebuild

Inland cruises on the rivers Danube and Dnieper have had a growing market in recent decades. Upstream from Kyiv, the Dnieper receives the water of the Pripyat River . This navigable river connects to the Dnieper-Bug canal , the link with the Bug River . Historically, a connection with
1230-522: The pressure ratio produced is somewhat higher than that normally developed by a single stage fan. Owing to the low specific thrust, the bypass ratio for the engine is higher than normal for a military turbofan. This engine was required to power new versions of the L-39 trainer, L-39MS and L-59. Other turbofan engine models in the DV-2 family include the DV-2A, DV‑2A.2 and DV-2S. The DV-2S was renamed "RD-35" by

On the Dnieper the Varangians had to portage their ships round seven rapids, where they had to be on guard for Pecheneg nomads. Along this middle flow of the Dnieper, there were 9 major rapids (although some sources cite a smaller number), obstructing almost
