Soviet Destroyer Strogy (1967)
''Strogy'' was a of the Soviet Navy. Development and design Late 1950s and 1960s was an era of great changes in the history of the navy, new opportunities and new weapons. This was primarily due to the emergence of sea-based nuclear missiles, which turned submarines into strategic weapons. The appearance of nuclear power plants on submarines had greatly increased their autonomy, cruising range, underwater speed and, as a consequence, the severity of the threat they created. From the very beginning, two options for the main power plant were considered - a traditional steam turbine (STU) or a gas turbine (GTU). The latter, due to its lightness and compactness (specific gravity 5.2 kg / l. From. Versus 9 kg / l. From.), Reduced the ship's displacement from 3600 to 3200 tons and increased its efficiency. In addition, starting from a cold state took 5–10 minutes for the GTU compared to the several hours required for the STU. For these reasons, the option with gas tur ...

Strict
In mathematical writing, the term strict refers to the property of excluding equality and equivalence and often occurs in the context of inequality and monotonic functions. It is often attached to a technical term to indicate that the exclusive meaning of the term is to be understood. The opposite is non-strict, which is often understood to be the case but can be put explicitly for clarity. In some contexts, the word "proper" can also be used as a mathematical synonym for "strict". Use This term is commonly used in the context of inequalities — the phrase "strictly less than" means "less than and not equal to" (likewise "strictly greater than" means "greater than and not equal to"). More generally, a strict partial order, strict total order, and strict weak order exclude equality and equivalence. When comparing numbers to zero, the phrases "strictly positive" and "strictly negative" mean "positive and not equal to zero" and "negative and not equal to zero", respectivel ...

Helipad
A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing aircraft (VTOL), may be called ''vertiports.'' An example is Vertiport Chicago, which opened in 2015. Usage Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located remote from populated areas due to sounds, winds, space and cost constraints. However, some skyscrapers maintain a helipad on their roofs in order to accommodate air taxi services. Some basic helipads are built on top of highrise buildings for evacuation in case of a major fire outbreak. Major police departments may use a ...

Ships Built At Shipyard Named After 61 Communards
A ship is a large watercraft that travels the world's oceans and other sufficiently deep Sea lane, waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, Naval warfare, warfare, Human migration, migration, colonization, and science. After the 15th century, Columbian Exchange, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Cruiser Nikolayev
''Nikolayev'' was the lead ship of the s of the Soviet Navy. She was launched on 19 December 1969 and commissioned on 31 December 1971 at the Mykolayiv Shipyard, 61 Communards Shipyard. On 8 February 1972, she became part of the 30th Surface Ship Division of the Black Sea Fleet. Between 26 September–1 October 1973, she paid a visit to Split, Croatia, Split, Yugoslavia, and between 15–21 April 1981 to Havana, Cuba. On 9 April 1984 she was reassigned to the Pacific Fleet (Russia), Pacific Fleet. On 16 July 1986 at night, she collided with destroyer during the exercises in the Sea of Japan. After light repairs at Dalzavod, Vladivostok, she made a transition to Sevastopol, and then Nikolayev. On 1 November 1987, ''Nikolayev'' was delivered to Nikolayev for major repairs. In April 1992, the repairs were cancelled and on 29 October 1992, she was decommissioned. On 10 August 1994, she was towed for scrapping in India.

Kara-class Cruiser
The Kara class, Soviet designation Project 1134B Berkut B ( golden eagle), was a class of guided missile cruisers (large anti-submarine warfare ship in Soviet classification) built in the Soviet Union for the Soviet Navy. The NATO lists the class as "cruisers" mainly due to the Metel (SS-N-14 ''Silex'') anti-ship missile system capable of striking not only submarines, but also surface vessels. Design These ships were enlarged versions of the , with gas turbine engines replacing the steam turbines. These ships were fitted as flagships with improved command, control and communications facilities. These are dedicated ASW ships with significant anti-aircraft capability including both SA-N-3 and SA-N-4 surface-to-air missiles. The specifications for the class were issued in 1964 with the design being finalised in the late 1960s. The gas turbine engine was chosen instead of steam for greater efficiency and quietness, and because the main Soviet gas turbine plant had a long assoc ...

Commissioned (ship)
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launched (ship)
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZIS-101
The ZIS-101 was a limousine produced by the Soviet car manufacturer '' Zavod Imeni Stalina''. It was introduced in 1936. Its chassis was reverse-engineered from a Buick 33-90, except for the front suspension, engine, exhaust and battery carried over from 1933 experimental limousine L-1, itself an unlicensed Buick 32-90 copy, but the body was designed by Budd Company for whopping $1,500,000 while the stamps were made by Hamilton Foundry & Machine Company for another $500,000. It was equipped with an straight-eight OHV engine (a metric copy of Buick 345) producing up to and giving a top speed of . The car was fitted with a 3-speed manual gearbox. It was followed by the ZIS-101A that had improved the engine giving and a new top speed of approximately . Production ended in 1941 with over 8,000 cars built. In 1939, a two-seat sport version designed by Valentin Nikolaevich Rostkov called 101-Sport was built. The engine was the same as in the 101-A, but boosted to and a top spe ...
