"Turbine blades" refers to the small, rotating parts inside a turbine that are shaped like a fan. They use the force of air or steam to spin the turbine and generate power.
Full definition

The performance of offshore wind
turbine blades in their challenging operating environment is one of the critical issues in energy cost, reliability and safety.
The ability to operate
turbine blades at higher temperatures improves efficiency and reduces energy costs.
Most of the sound generated by wind turbines is aerodynamic, caused by the movement of
turbine blades through the air.
All of these factors can spell trouble, especially given the fact that
turbine blade tips can spin as fast as 180 miles per hour.
Problems with engine
turbine blades wearing out sooner than expected have hampered a restructuring programme prompted by the engineering company's declining older engine programmes and plunging demand for oil equipment.
He notes the new technique could someday be used on
jet turbine blades, for example, to more accurately assess their integrity and durability.
Once it was determined that the birds would fly safely out of the way of
giant turbine blades, construction began.
Wind
power turbine blades are made using plastics and chemical additives, helping deliver renewable energy to our nation's electricity grid.
As the demand for sustainable energy rises, see how the wind industry is responding by building bigger and more
powerful turbine blades.
The tip of the
highest turbine blade at the wind farm stretches close to 500 feet in the air above the base.
We've been trying to create streamlined designs ourselves for structures such as
wind turbine blades.
It's for this reason that
turbine blades in some jet engines or generators are actually formed from single crystals of nickel - based alloy.
For example, though there are a variety of methods to minimize the impact (including fish ladders and in - take screens), fish and other organisms can be injured and killed
by turbine blades.
France is building the world's first wind farm with
turbine blades designed to minimize interference with radar systems, using technology partially inspired by stealth warplanes.
We are importing wind
turbine blades from Denmark, solar panels from China and nuclear expertise from France, because there is not a sufficiently firm commitment to any technology to give companies the confidence to invest in Britain.»
LM Wind Power's wind
turbine blades made from a unique blend of carbon and glass fiber and other materials are the lightest in the world.
The VR30 uses a new turbine speed sensor and

turbine blade manufactured in Spain to date, 73.5 m (241ft), was transported from the factory to the port in Castellón, Spain on October 20th.
In addition, Hu is investigating how turbine operators can compensate for weather effects like icing
on turbine blades.
Many people assume fish swimming through dams are only injured
when turbine blades hit them, but PNNL's research has shown there are many different forces that can harm fish, including abrupt pressure changes in dam turbine chambers.
Rearranging, the power per area is Wind
turbine blades do not extract all of the available power out of the wind.
Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy -
efficient turbine blades thanks to a partnership between the U.S. Department of Energy's Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State.
The nickel - based
turbine blades used in these systems melt at temperatures 200 °C lower and thus require air - cooling to function.
Siemens has achieved a breakthrough by finishing its first full load engine tests for
gas turbine blades completely produced using Additive Manufacturing (AM) technology.
They tested a revised operating procedure
slowing turbine blades to near motionless in low - wind periods significantly reduces bat mortality.

Turbine Blade Failure — In Dekalb County, Illinois, residents blog about what life is like now that the turbines have been installed.
«Whilst the aerodynamic noise from a rotating
turbine blade produces energy in the infrasound range, measurements of infrasound noise emissions from modern upwind turbines indicates that at distances of 200 metres, infrasound is in the order of 25 dB below the recognised perception threshold of 85 dB (G) and other similar recognised perception thresholds (Hayes Mckenzie Partnership Ltd, 2006).
Such high - efficiency energy conversion dictates the use of lift -
type turbine blades, similar to airplane wings, of twisted and tapered airfoil shapes.
They have also been used in experiments to
strengthen turbine blades and in thermoelectric applications, that is trying to convert heat gradient directly into electricity.
Other concerns include whether the noise of the turbine could attract or repel fish and
whether turbine blades could strike and kill fish as they swim through them.
Wings also operate under drier conditions when they're at altitude;
turbine blades near the surface are in the middle of winter sleet and snow.
