6.4.6 Concluding Remarks

. 1.. The.power.wind.turbine.blades.model.with.a.protective.covering.

of.luminescent.paint.can.be.used.for.nonintrusive.pressure.(PSP).
and.temperature.(TSP).measurements..The.nonintrusive.pressure/
temperature. measurement. system. can. be. used. by. nonstandard.
conditions,. such. as. storms,. hurricanes,. etc.,. for. determining. the.
turbulent.layer.parameters.

. 2.. Smart. paint. material. managed. from. cover. layers. can. protect. wind.

turbine.blades.from.impact.loads.and.reduce.noise.and.vibration.

. 3.. The.information.about.changing.hydrostatic.pressure,.temperature,.

and.moisture.can.be.developed.to.help.aerodynamic.characteristics.
and.safe.conditions.

. 4.. UV/visible.light.can.help.launch.a.service.to.regulate.turbine.blade.

driving.procedures.
