通读全文,结合第段中“Not unlike the wings of airplanes, the blades (叶片) of wind turbines (涡轮机) need to be kept ice-free in order to function properly. Scientists have now developed an inexpensive method of using drones (无人机) to apply an eco-friendly anti-icing coating (涂层) ...

Hydroelectric power is generated by running the turbine blades by the energy of the flowing water and thus producing electricity from the generator coupled to the turbines. Production of electric power by using the energy of the flowing water is an excellent use of water as no water is consumed...
System of blades cooled by means of spiral guide surface, cascade collision and system with bridges in double shell FIELD: mechanical engineering; turbines; cooled turbine blades. SUBSTANCE: inner space of proposed blade is divided into three spaces 11, 12, 13 by two radial partitions 9.10. Fron...
Wind turbines and bat mortality: Doppler shift profiles and ultrasonic bat-like pulse reflection from moving turbine blades Bat mortality resulting from actual or near-collision with operational wind turbine rotors is a phenomenon that is widespread but not well understood. Beca... CV Long,JA Flint...
The research project is known as “TURBO: Temporary coating by means of drones — Icing protection of wind turbines as a case study”. In the current version of the resulting system, a hexacopter drone is equipped with a small pump that delivers anti-icing liquid. The liquid is sprayed (...
This kind of damper was first proposed in [13] to control wind induced vibrations in two television towers. Recently, the roller damper was investigated in [7] for mitigating tower vibrations of offshore wind turbines, and both experimental and numerical results show the efficacy of roller ...
Wind-farm owners in Europe are holding off on scrapping their old turbines to maximize the power they can generate from them. That's the latest news from a meeting we recently attended on the industry's future. Wind turbines ...
