Turbine \Tur"bine\, n. [L. turbo, -inis, that which spins or whirls round, whirl.]

  1. A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel.

    Note: In some turbines, the water is supplied to the wheel from below, instead of above. Turbines in which the water flows in a direction parallel to the axis are called parallel-flow turbines.

  2. A type of rotary engine with a set of rotating vanes, diagonally inclined and often curved, attached to a central spindle, and obtaining its motive force from the passage of a fluid, as water, steam, or air, over the vanes. Water turbines are frequently used for generating power at hydroelectric power stations, and steam turbines are used for generating power from coal- or oil-fired electric power stations. Turbines are also found in jet engines, and in some automobile engines.

    Note: In the 1913 dictionary, the turbine was further decribed thus: ``There are practically only two distinct kinds, and they are typified in the de Laval and the Parsons and Curtis turbines. The

    de Laval turbine is an impulse turbine, in which steam impinges upon revolving blades from a flared nozzle. The flare of the nozzle causes expansion of the steam, and hence changes its pressure energy into kinetic energy. An enormous velocity (30,000 revolutions per minute in the 5 H. P. size) is requisite for high efficiency, and the machine has therefore to be geared down to be of practical use. Some recent development of this type include turbines formed of several de Laval elements compounded as in the ordinary expansion engine. The Parsons turbine is an impulse-and-reaction turbine, usually of the axial type. The steam is constrained to pass successively through alternate rows of fixed and moving blades, being expanded down to a condenser pressure of about 1 lb. per square inch absolute. The Curtis turbine is somewhat simpler than the Parsons, and consists of elements each of which has at least two rows of moving blades and one row of stationary. The bucket velocity is lowered by fractional velocity reduction. Both the Parsons and Curtis turbines are suitable for driving dynamos and steamships directly. In efficiency, lightness, and bulk for a given power, they compare favorably with reciprocating engines.''

Douglas Harper's Etymology Dictionary

1838, from French turbine (19c.), from Latin turbinem (nominative turbo) "spinning top, eddy, whirlwind, that which whirls," related to turba "turmoil, crowd" (see turbid). Originally applied to a wheel spinning on a vertical axis driven by falling water. Turbo in reference to gas turbine engines is attested from 1904.


n. Any of various rotary machines that use the kinetic energy of a continuous stream of fluid (a liquid or a gas) to turn a shaft.


n. rotary engine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate

Turbine (disambiguation)

A turbine is a rotary engine that extracts energy from a fluid flow.

Turbine may also refer to:


A turbine (from the Latin turbo, a vortex, related to the Greek , tyrbē, meaning " turbulence") is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels.

Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to British engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to Swedish engineer Gustaf de Laval (1845–1913) for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

The word "turbine" was coined in 1822 by the French mining engineer Claude Burdin from the Latin turbo, or vortex, in a memo, "Des turbines hydrauliques ou machines rotatoires à grande vitesse", which he submitted to the Académie royale des sciences in Paris. Benoit Fourneyron, a former student of Claude Burdin, built the first practical water turbine.

TURBINE (US government project)

TURBINE is the codename of an automated system which in essence enables the automated management and control of a large network of implants (a form of remotely transmitted malware on selected individual computer devices or in bulk on tens of thousands of devices).

The NSA has built an infrastructure which enables it to covertly hack into computers on a mass scale by using automated systems that reduce the level of human oversight in the process. As quoted by The Intercept, TURBINE is designed to "allow the current implant network to scale to large size (millions of implants) by creating a system that does automated control implants by groups instead of individually." The NSA has shared many of its files on the use of implants with its counterparts in the so-called Five Eyes surveillance alliance – the United Kingdom, Canada, New Zealand, and Australia.

Among other things due to TURBINE and its control over the implants the NSA is capable of:

  • breaking into targeted computers and to siphoning out data from foreign Internet and phone networks
  • infecting a target's computer and exfiltrating files from a hard drive
  • covertly recording audio from a computer’s microphone and taking snapshots with its webcam
  • launching cyberattacks by corrupting and disrupting file downloads or denying access to websites
  • exfiltrating data from removable flash drives that connect to an infected computer

The TURBINE implants are linked to, and relies upon, a large network of clandestine surveillance "sensors" that the NSA has installed at locations across the world, including the agency's headquarters in Maryland ( Fort George G. Meade) and eavesdropping bases used by the agency in Misawa, Japan ( Misawa Air Base) and Menwith Hill, England ( RAF Menwith Hill). Codenamed as TURMOIL, the sensors operate as a sort of high-tech surveillance dragnet, monitoring packets of data as they are sent across the Internet. When TURBINE implants exfiltrate data from infected computer systems, the TURMOIL sensors automatically identify the data and return it to the NSA for analysis. And when targets are communicating, the TURMOIL system can be used to send alerts or "tips" to TURBINE, enabling the initiation of a malware attack. To identify surveillance targets, the NSA uses a series of data "selectors" as they flow across Internet cables. These selectors can include email addresses, IP addresses, or the unique " cookies" containing a username or other identifying information that are sent to a user's computer by websites such as Google, Facebook, Hotmail, Yahoo, and Twitter, unique Google advertising cookies that track browsing habits, unique encryption key fingerprints that can be traced to a specific user, and computer IDs that are sent across the Internet when a Windows computer crashes or updates.

Usage examples of "turbine".

The turbines aft of maneuvering, so loud before, like jet engines screaming mere feet away, spun down, their steam gone.

One of the turbine generators and one of the main engines aft was shut down to minimize radiated noise.

The deck began to tremble as the huge twin steam propulsion turbines aft came up to full revolutions, blasting the Tampa through the water at one hundred percent reactor power.

Those forward turbines are the SSTGs and the aft ones are the main engines.

The explosion blew apart what had been left of the superstructure, taking with it the masts and antennae as the ship erupted into flames amidships, the fire migrating aft to the fuel tanks, where ruptured fuel lines spewed volatile fuel for the gas turbines into the bilges.

The steam in the headers filled the space with roaring heat and the sound of the turbines whining at thirty-six hundred RPM aft of maneuvering was the sweetest sound Vaughn could remember hearing.

Finally, his F-14 was lined up on catapult one, the deck sailors attaching the catapult to the nose gear Collins checked his instruments, the twin turbines purring aft, waiting to be kicked into full thrust.

With the plant critical, the rods only affected coolant temperature, but when the plant was shut down the rods were withdrawn to start the nuclear fission reactions that heated the main coolant water, boiling the water in the steam generators and thereby providing steam to the turbines.

The port steam system was useless with the condenser isolated from the seawater flooding, which left one coolant loop and one steam generator to power one electrical turbine and one main engine.

If they lost power now there would be no main coolant pumps circulating hot water to the boilers, no steam and no turbine generators.

The power station next door has already shut down its turbines and evacuated all but a skeleton staff.

Inertia would tear a turbine that got away from its handlers right on through the fuzzily transparent walls.
