turb-, turbin-, turbo-, turbu-
(Latin: uproar, commotion, disorderly, agitated, confusion; whirl, whirlwind)
2. A jet engine with a gas turbine that uses exhaust gases to provide the propulsive thrust for an aircraft.
An aircraft employing such an engine; the earliest form of jet aircraft in the late 1930s.
2. An aircraft whose propellers are driven by a gas turbine.
3. An airplane equipped with two or more turbo-propeller engines.
2. A state of disorder, disarray, or agitation in nature; for example, an irregular motion of the atmosphere, as manifested by wind gusts and lulls; or a secondary motion of water caused by eddies in a moving flow.
3. The chaotic or unstable eddying motion in a fluid.
Avoiding excessive turbulence generated around moving objects; such as, aircraft, which can make their motion inefficient and difficult to control, is a major factor in aerodynamic designing.
2. A condition of disorder, disarray, or agitation in nature.
2. Characterized by, or showing disturbance, disorder, etc.: "Many people go through turbulent years before they can find their peaceful years."
3. Given to acts of violence and aggression: "The turbulent young soldiers could not control themselves after their comrade was killed."
4. Full of violent motion and agitation; such as, turbulent rapids.
5. Chaotic and restless: marked by disturbances, changes, and unrest: "It has been a turbulent year in politics."
6. In meteorology, atmospherically unstable, with variations in wind speed and direction.
2. In a stormy or violent manner.
3. A description of being violently agitated or disturbed; tumultuous.
4. Characteristic of a chaotic or restless character or tendency; such as, a turbulent period in history.
5. A reference to a something which shows unrest or disturbance; unruly: "Early in the history of our country, there were turbulent or revolutionary undercurrents."
About one-fifth of the Denmark's electricity comes from wind, which wind experts say is the highest proportion of any country.
A closer look shows that Denmark is a far cry from a clean-energy paradise.
The building of wind turbines has virtually ground to a halt since subsidies were cut back.
Meanwhile, compared with others in the European Union, Danes remain above-average emitters of the greenhouse gas carbon dioxide.
For all of its wind turbines, a large proportion of the rest of Denmark's power is generated by plants that burn imported coal.
The Danish experience shows how difficult it can be for countries grown rich on fossil fuels to switch to renewable energy sources like wind power.
Among the hurdles are fluctuating political priorities, the high cost of putting new turbines offshore, concern about public acceptance of large wind turbines, and the destructive volatility of the wind itself.
Some parts of western Denmark derive 100 percent of their peak needs from wind if the breeze is up.
Germany and Spain generate more power in absolute terms, but in those countries wind still accounts for a far smaller proportion of the electricity generated. The average for all 27 European Union countries is three percent.
The Germans and the Spanish are catching up as Denmark slows down.
