Embodiment Construction

[0053] figure 1 A first blade inspection method according to the invention is shown.

[0054] According to the invention, the relevant segment or part of the blade BL is examined by a method based on computer tomography.

[0055] The first transmitter AS and the second transmitter BS transmit a radiation through the blade BL for inspection.

[0056] X-rays are used as radiation for leaf inspection. The radiation is directed by means of a steering system.

[0057] The first receiver AR and the second receiver BR receive the radiation after it has passed through the blade BL.

[0058] The positions of the transmitters AS, BS and the receivers AR, BR are changed relative to each other to perform the inspection of the blade BL.

[0059] In this case, the position of the receiver AR, BR and / or the transmitter AS, BS is changed in a linear fashion along the dedicated line to allow inspection of the blade BL.

[0060] In this case, two beams are used, which are scanned through t...

Abstract

The invention relates to a method to inspect the quality of a blade, especially of a wind-turbine-blade. At least parts of the blade are inspected by a computer-tomography-method using radiation. The radiation is directed through the blade for the inspection. A transmitter sends the radiation through the blade. A receiver receives the sent radiation after its passing through the blade. The position of the transmitter, of the receiver and / or of the blade is changed in relation to each other, to perform the inspection of the blade.

Description

technical field [0001] The invention relates to a method for determining the mass of a blade, in particular a wind turbine blade. Background technique [0002] Blades, especially wind turbine blades, are produced with the aid of synthetic materials, since this makes it possible to achieve significant mechanical strength and reduced weight. [0003] Preferably, the wind turbine blade is manufactured by using the so-called "Vacuum Assisted Resin Transfer Molding, VARTM". In order to guarantee the quality of the blades, there is a need to reduce or even avoid defects during the production process, since these defects may lead to a reduced lifetime of the blades or even lead to the eventual scrapping of the produced blades. [0004] VARTM is used to create composite structures by means of vacuum. A vacuum is applied to the parts of the blade as they are positioned into the closed die. A vacuum is applied to the closed mold, thus forcing resin, such as epoxy, into the closed m...
