turb-, turbin-, turbo-, turbu- +

In mechanical engineering, a centrifugal or axial-flow compressor.

1. A specialized turbine driven by the exhaust gases of an engine that supplies air under pressure to the engine for combustion.
2. An exhaust gas-driven device consisting of a shaft with two vaned fan-type wheels at each end.

At the hot end, the turbine wheel is driven by the hot pressurized exhaust gases, while at the opposite end, the compressor wheel pressurizes the ambient air supply into the engine intake manifold.

A rotary drill used in oil or gas drilling operations, driven by a turbine motor located inside the well.

1. A jet engine in which fans driven by a turbine force air into the exhaust gases, thereby increasing the propelling thrust of the engine.
2. A jet aircraft that has turbofan engines.

A type of gas turbine in which the fan driving air into a turbojet also forces additional air around the outside of the turbine, combining it with the exhaust of the turbojet to provide thrust.

Turbofans are quieter than simple turbojets and somewhat more fuel efficient, and are widely used in commercial aircraft.

A fighter aircraft propelled by a turbojet engine.

1. A jet engine propelled by the simplest form of gas turbine which utilizes a compressor, combustion chamber, and turbine; with the turbine drawing just enough energy from the gas flow to drive the compressor.
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.

A process for the secondary milling and sorting of high-protein flour, using high-speed turbo grinders and centrifugal force to separate finer high-protein particles from the coarser starchy fraction.

The upper and lower boundaries of the turbosphere in which rapid changes in air pressure and uneven air motions occur.

1. A turbojet engine that powers a propeller.
2. An aircraft whose propellers are driven by a gas turbine.
3. An airplane equipped with two or more turbo-propeller engines.

The atmospheric region characterized by turbulence.

A flatfish that is almost circular with bony tubercles on its body and both eyes on the left side. Native to: Europe.

1. A state of violent disturbance and disorder; such as, in politics or general social conditions.
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.

1. An unstable flow of a liquid or gas.>BR? 2. A condition of disorder, disarray, or agitation in nature.

1. Being in a state of agitation or tumult; disturbed: "He had turbulent feelings or emotions after being rejected by the coach."
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.

1. In a turbulent manner; with turbulence>
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."
