The Front CoverDynamic rotor geometry measurement (DRGM), developed by windcomp between 2008 and 2010, is a method for the verification of the aerodynamic condition and the aeroelastic behaviour of a wind turbine rotor and the turbine tower system. On page 7 you can read the full article about it.Publisher's NoteTen years of the latest technological developmentsFeatures

The Front CoverThe Pseudo Direct Drive is a magnetically geared generator. It is a magnetic and mechanical integration of a magnetic planetary gear with a permanent magnet generator (PMG). It has reduced size and mass and improved efficiency compared to other direct drive generators.This generator enables a front-mounted kingpin turbine architecture that can be scaled to 10MW and beyond. On page 6 you can read the full article about this generator.Publisher's NoteBig potential for US offshore industry and China back on trackFeatures

The Front CoverThe contemporary trend is to carry out quality inspection on rotor blades in vertical orientation. FORCE Technology recently announced their vertical blade scanners for automated ultrasonic NDT inspection. A couple of different concept are available and commercialised. On page 7 you can read more about automated scanning for quality assurance.Publisher's NoteA preview of the global on- and offshore expoFeatures

The Front CoverThe Lux turbine is a vertical axis wind turbine (VAWT) using six blades, which does not need the support of a central structure or tower. Instead, cables or beams are attached to the blades travelling from blade to blade forming the shape of a hexagon. The cables cross each other at the mid-point between each blade, forming triangular shapes. This pattern provides rigidity to the rotor and closely resembles the geodesic dome, thus ‘building more with less’.Publisher's NoteGlobal wind market rebounds in 2014Features

The Front CoverThe emerging airborne wind sector continues to grow as small companies around the globe edge closer to commercialising innovative technologies. Boston-based Altaeros is set to demonstrate its technology in Alaska in 2015. The US$ 1.3 million demonstration is partially financed by the Alaska Energy Authority and will run for 18 months. The project is currently being permitted for a site south of Fairbanks. Throughout the winter of 2012, the Altaeros team demonstrated its BAT Concept Prototype in Maine.Publisher's NoteNew vision previewed in Las Vegas for the US wind industryFeatures

The Front CoverStudies of early offshore turbines showed that the impact of the harsh conditions on the whole turbine structure was much higher than expected. Only proper maintenance procedures, including periodic surveys at predetermined time intervals, can secure the long-term production efficiency and yield from offshore wind turbines and their blades. The required technologies for maintenance on offshore installations are currently being developed and more are becoming available every year. The image on the front cover shows automated NDT inspection on offshore rotor blades by SPRAT rope access.Publisher's NoteEWEA 2014: Optimistic vibe, new turbines and focus on bringing down CoEFeatures

The Front CoverThe small-wind power market is expected to increase hugely, from US$ 609 million in 2012 to US$ 3 billion by 2020. The global small-wind turbine cumulative installed capacity is also expected to witness a significant increase, from 728.3MW in 2012 to 4,644.7MW by 2020. In this issue you will find an article on page 7 about a small-wind turbine. According to the Ireland-based company Airsynergy, its new turbines can double the power output for less than a 20% increase in the capital cost.Publisher's NoteSmall-wind power market to grow extensivelyFeatures
