Astern, английский
- In back of the boat, opposite of ahead.
- In the back of the ship, opposite of ahead
- 1. toward the stern (rear) of a vessel.
- A backward direction in the line of a vessel`s fore and aft line; behind. if a vessel moves backwards it is said to move astern; opposite to ahead.
- На корме, за кормой, позади, назад
- За кормой, позади яхты
- Behind the slem of the boat.
- За кормой, у кормы
- Any distance behind a vessel; in the after-part of the ship; in the direction of the stern, and therefore the opposite of ahead.—to drop astern, is to be left behind,—when abaft a right angle to the keel at the main-mast, she drops astern.
- [1] behind the vessel. [2] to move backward (go astern). astern all!: the shout of a harpooner telling the boat’s crew to backwater when a whale is struck.
- Anywhere behind the boat, a reverse direction, opposite of ahead.
- Toward the stern of a vessel, or behind the boat.
Astern, английский
Backwards, somewhere behind the vessel, or towards or behind the stern.
Astern refueling, английский
The transfer of fuel at sea during which the receiving ship keeps station astern of the delivering ship. see underway replenishment, replenishment at sea.
Astern steering test, английский
Gear, английский
- Engrenage
- A machine part which transmits motion and force by means of successively engaging projections, called teeth. the smaller gear of a pair is called the pinion; the larger, the gear. when the pinion is on the driving shaft, the gear set acts as a speed reducer; when the gear drives, the set acts as a speed multiplier. the basic gear type is the spur gear, or straight-tooth gear, with teethe cut parallel to the gear axis. spur gears transmit power in applications utilizing parallel shafts. in this type of gear, the teeth mesh along their full length, creating a sudden shift in load from one tooth to the next, with consequent noise and vibration. this problem is overcome by the helical gear, which has teeth cut at an angle to the center of rotation, so that the load is transferred progressively along the length of the tooth from one edge of the gear to the other. when the shafts are not parallel, the most common gear type used is the bevel gear, with teeth cut on a sloping gear face, rather than parallel to the shaft. the spiral bevel gear has teeth cut at an angle to the plane of rotation, which, like the helical gear, reduces vibration and noise. a hypoid gear resembles a spiral bevel gear, except that the pinion is offset so that its axis does not intersect the gear axis; it is widely used in automobiles between the engine driveshaft and the rear axle. offset of the axes of hypoid gears introduces additional sliding between the teeth, which, when combined with high loads, requires a high-quality ep oil. a worm gear consists of a spirally grooved screw moving against a tooth wheel; in this type of gear, where the load is transmitted across sliding, rather than rolling surfaces, compounded oils or ep oils are usually necessary to maintain effective lubrication.
- Редуктор; коробка передач
- A general term for ropes, blocks, tackle and other equipment
- A catchall nautical term covering [1] any assembly of sails, lines, tackles, etc. [2] the personal effects of a crew member. [3] a toothed wheel that meshes with another to provide a mechanical advantage, to increase force or speed, or to reverse direction.
- A synonym for feed gear.
- The accessory tools and equipment required to op erate a drill.
- A set of enmeshing-toothed rotating parts or cog wheels designed to transmit motion.
- Generic term for the tools of fishing – rod and reel, hook and line, etc.

- Passage of electromagnetic radiation through a medium.
- Transmisión
- The property in a merchantman, or a share therein, transmitted in
- Передача; привод; коробка передач; трансмиссия; прохождение; распространение ~ of loads передача нагрузок
- The transport of high voltage electricity. this is achieved with a transmission network (or grid). generally the network will connect large generators to lower voltage distribution networks where it will be transported to the majority of electricity consumers. alternatively, large scale electricity users may connect directly to the transmission network. management of transmission is a natural monopoly due to the economies of scale inherent to it. transmission system operator (tso) (also transmission network operator-

- The transportation of electric energy in bulk from a source or sources of supply to other systems or parts of a single system.

Sea state, английский
- The general condition of the free surface on a large body of water with respect to wind waves and swell at a certain location and moment, characterized by statistics, including the wave height, period, and power spectrum. the sea state varies with time, as the wind conditions or swell conditions change.
- A numerical or written representation of the roughness of the ocean surface, categorizing the force of progressively higher seas by wave characteristics, and the relationship of wind to waves. the large number of variables involved cannot be quickly and easily summarized, so simpler scales are used to give concise, approximate, descriptions, primarily for reporting in a ship’s log or similar record. see beaufort scale, douglas scale, and tables 1–5.
Jigger-mast, английский
The fourth mast, although ships with four or more masts were uncommon, or the aft most mast where it is smallest on vessels of less than four masts.
