Abstract:
Wind turbine blade (1) comprising a first blade part (2) and a second blade part (3), said blade parts (2, 3) being bonded by bonding means forming a bond (4). To reduce peel stresses of the bond and reduce the risk of crack formation, an edge portion of the bond (4) is covered by a low elastic modulus adhesive joint (5) bridging a gap between the first blade part (2) and the second blade part (3).
Abstract:
A wind turbine blade has a blade body and a leading edge fairing. The blade body has a root, a tip, and a longitudinal direction extending between the root and the tip. The 5 blade body also has a channel extending in the longitudinal direction. The leading edge fairing has a projection extending into the channel and extending in the longitudinal direction so as to be received in the channel. Also, a leading edge fairing for attachment to a blade body of a wind turbine blade; a method of fitting a leading edge fairing to a wind turbine blade; and a kit of parts with a number of the leading edge fairings.
Abstract:
A covering for a wind turbine blade (20). The covering may have a film (30) having at least one aerodynamic device (42, 43) pre-attached to it. In the manufacture of a wind turbine blade, the film having the aerodynamic device (42, 43) pre-attached is attached to a shell of a wind turbine blade (20).

Abstract:
A method of making a structural component (80) of a wind turbine blade (90) comprises providing an elongate composite strip (10) comprising structural fibres disposed in a thermoplastic matrix, the strip comprising an end portion (22) defining an end (24) of the strip, heating the end portion of the strip and shaping the end portion of the strip to form a tapered end (30) of the strip.

Abstract:
A time dimension management system is provided for managing time dimension of a data analyzing system for analyzing data stored in a data store based on a time data structure. The time dimension management system comprises a date selector controller and a calendar coordinator. The date selector controller is provided for controlling a date selector that presents to a user a standard calendar and a business calendar. The date selector controller has a standard calendar manager for managing presentation of the standard calendar for allowing the user to select a date on the standard calendar, and a business calendar manager for managing presentation of the business calendar to represent the time data structure that the data analyzing system uses, and allowing the user to select a date on the business calendar. The calendar coordinator is provided for coordinating the standard calendar manager and the business calendar manager to indicate a selected date on the standard calendar and the business calendar.
