Along with serving as a warning system, though, the setup could also be used simply to study the behaviour of rotor blades, helping in the design of longer-lasting, better-performing models. Although ...

With the vibration tests, deformations can be recorded with millimetre accuracy and material stresses analysed Five hundred sensors measure the structural dynamics directly on the rotor blade Funded ...

Specially shaped helicopter rotor blades with a kink at the outer part make it possible to reduce the radiating annoying rotor noise [1]. Against this background, the aeroelastic behaviour together ...

Boeing’s development of an advanced blade for the tandem-rotor CH-47 Chinook is moving ahead, with the first blade “about to finish this week” ahead of flight trials in 2016. The new blade design has ...

Model tests were conducted in a wind tunnel to arrive at an optimum configuration of Savonius rotor windmill. Effects of three design parameters, namely rotor shape, overlap between rotor blades, and ...

Siemens has created a special mechanism for mounting its 75-meter-long rotor blades for offshore wind farms. The lifting system makes assembly work safer and lets construction take place at higher ...

Siemens has developed the world's longest wind turbine rotor blades and is due to install them off the coast of Denmark by autumn 2012. The 75-metre-long rotors will fit in nicely with the local ...

Carbon-glass hybrid rotor blades will come to dominate the global wind market in the coming decade as supersize next-generation models grow longer and cost continues to need to be squeezed out if OEMs ...

FAA last week issued an emergency airworthiness directive (AD 2012-02-51) calling for replacement of certain Bell Model 206L (and -1, -3 and -4) main rotor blades that exceed a new shortened life ...
