Flettner rotators
| Морской словарь |
During the 1920s, german engineer anton flettner developed a method of ship propulsion based on the magnus effect. magnus had noted that when air flow is perpendicular to a vertical cylinder, the air current simply splits to pass on both sides of the cylinder. however, if the cylinder is rotating, the air current on one side is augmented by the cylinder’s rotation; while the current on the opposite side is slowed down. this creates a pressure differential, which results in a force pushing in one direction. flettner’s experimental prototype, a converted schooner named baden-baden, made a successful trans–atlantic crossing, arriving at new york in may 1926. this led the german naval transport service to commission barbara, a 92 meter (300 foot) vessel, with three flettner rotators mounted vertically on the weather deck. each was 17 meters (55 feet) tall and 4 meters (13 feet) in diameter, driven at 250 rpm by an electric motor. for six years, barbara carried freight and passengers between hamburg and italy. however, with an abundance of low cost fossil fuels, the rotator system was unable to compete with conventional engines and fell into disuse. flettner then turned his attention to aerodynamics, using the magnus principle to create lift. his prototype rotary wing aircraft flew in 1932 and, seven years later, the kriegsmarine (nazi german navy) ordered a more advanced model, the fl-282 kolibri. it flew anti-submarine patrols from surface warships in the baltic, mediterranean, and aegean sea, thus becoming the world’s first operational military helicopter. recently, with rising costs and restricted fuel supplies, interest in the marine system has revived. in august 2008, enercon, one of europe’s biggest wind turbine manufacturers, launched e-ship 1 (this name was only meant to identify the project, but it caught on so well that enercon decided to use it for the actual ship). fuel savings of 30–40 percent are expected, thanks to the auxiliary power of paired 27-meter (89-foot) high, 4-meter diameter, flettner rotators, mounted two forward and two aft. a ship equipped with turbosails looks virtually identical to one with flettner rotators, but operates on a different principle. it is hard to believe that either of these vessels—having tall windcatching elements that cannot be furled—would fare well in a storm.

Propulsion, английский
- (реактивное) движение; силовая [двигательная] установка; двигатель
- Cредства движения; движение
- Marine propulsion is the act of moving an object through the water or across its surface. poles, paddles, and oars were the earliest forms, while sails represented the most significant historical method. today, common types are underwater propeller, water-jet, paddle wheel and, experimentally, magnetohydrodynamic drive.
Perpendicular, английский
- Перпендикуляр; перпендикулярный
- A right line falling from or standing upon another vertically, and making the angle of 90° on both sides.
- Перпендикуляр
Differential, английский
- Дифференциал; разность; перепад; дифференциальный
- Разность; перепад (давлений)
- N дифференциал semantic ~ псхлнгв. семантический диффе- ренциал5 differentiated a дифференцированный; over-~ сверхдифференцированный 1 один из возможных способов синтаксической реализации семантиче- ских актантов предиката. 2 словарь языка писателя, философа или общественного деятеля; до 1990-х гг. в отеч. лит. бытовал термин «писательский словарь». 3 словарь с указанием норм произношения. 4 англ. термином reverse dictionary (rd) и русским обратный словарь называются разные вещи. в rd реализуется принцип «от значения к слову», поэтому rd скорее являются словарями ассоциаций, нежели обратными словарями, где слова расположены в обратном (инверси- онном) порядке. 5 метод качественно-количественного индексирования значения слова с помощью двухполюсных шкал, на каждой из которых имеется града- ция с парой антонимических прилагательных.
- Разница в оплате труда квалифицированных и неквалифицированных рабочих одной отрасли или рабочих разных отраслей промышленности
- System of gears capable of dividing the input torque of one shaft between two output shafts where rotation at different speeds is ukely to occur, as in cornering. used as the final drive of vehicles with two or more driven wheels. see also crown wheel
- A system of gears that allows the outside driven wheel to rotate faster than the inside driven wheel when turning a corner. conventional “open” differentials direct engine power to the wheel with the least traction, which can be a problem on slippery surfaces. to combat this, some vehicles are equipped with “limited-slip” differentials that ensure some power is always delivered to both driven wheels.
- Difference in value between two comparable items
- Difference in value between two comparable items change in value of one item compared to another (for example, a “cost-of-living differential” is the difference between the price of goods bought in the home country compared to the price of similar goods in the host country)
Experimental, английский
- Экспериментальный
- A эксперимен- тальный phonetics
Successful, английский
It`s the combos of repeated consonants that can make spelling successful, well, unsuccessful. just know that it has the doubles in the middle (two "s`s" and two "c`s"), but only one consonant at the beginning and one at the end.
Commission, английский
- Комиссионные - вознаграждение, которое клиент должен заплатить брокеру при открытии и закрытии позиций по различным финансовым активам (акции, фьючерсы, опционы);
- Комиссия смт combustion горение, сгорание; воспламенение смт command module technician техник по командному модулю [модульному отсеку экипажа] кла смт corrected mean temperature исправленная средняя температура смтм communications and telemetry связь и телеметрия смто бр chief mechanical transport officer начальник транспортной службы
- To formally place (a naval vessel) into active service, after which the vessel is said to be in commission. sometimes used less formally to mean placing a commercial ship into service.
- Комиссия
- The authority by which an officer officiates in his post. also, an allowance paid to agents or factors for transacting the business of others.
- [1] to place a warship on active service. [2] the period during which a warship is assigned to specific duties. [3] a document conferring officer rank on an individual (excluding warrant, petty, and other non-commissioned officers). [4] a percentage of the selling price paid to a salesperson as payment for making the transaction. [5] a fee charged by a broker or agent for service in facilitating a business deal. [6] an official investigative body. [7] to contract for the production of something (e.g., a work of art).
- Ввести в эксплуатацию (напр., очистное сооружение)
- The amount, usually a percentage of the sales amount, paid to the salesperson making the sale.
- The fee paid to a broker to execute a trade, based on number of shares, bonds, options, and/or their dollar value. in 1975, deregulation led to the establishment of discount brokers, who charge lower commissions than full service brokers. full service brokers offer advice and usually have a staff of analysts who follow specific industries. discount brokers simply execute a client`s order and usually do not offer an opinion on a stock. also known as a round-turn. commissions are known as round-turn only in futures trading, since the commission is assessed only after liquidation of the position.
- Патент, выдаваемый мировому судье при назначении его на должность
- Комиссионные
- Real estate commission is generally 5-6% of the home’s sale price. that commission is usually split between the buyer’s and seller’s agents and is paid by the seller at the time of closing.
- The compensation paid to a licensed real estate broker or by the broker to the salesman for services rendered. usually a percentage of the selling price of the property.
