Abstract
A method and associated system are provided for bonding component parts of a wind turbine blade along a bond line. A barrier is placed within an internal cavity of the blade at a defined bond line width along the length of the bond line. A plurality of spaced apart external access ports are defined along the bond line into the internal cavity. A bond paste is sequentially injected into the plurality of access ports to fill the bond line.
Claims9
A method for bonding component parts of a wind turbine blade along a bond line, comprising:
- placing at least one barrier within an internal cavity of the blade at a defined bond line width along the length of the bond line;
- defining a plurality of spaced apart external access ports along the bond line, into the internal cavity;
- sequentially injecting a bond paste into the plurality of access ports to fill the bond line;
- wherein the method is used to form a bond line between upper and lower shell members of the turbine blade;
- wherein the sequentially injecting step includes injecting the bond paste into a plurality of hoses at the external access ports, wherein the injecting step is sequenced to a next subsequent hose upon detection of the bond paste at the respective next subsequent hose;
- and
- wherein presence of the bond paste at the next subsequent hose is determined by detecting a change in air pressure in the hose caused by the presence of the bond paste within the internal cavity migrating to the hose.
