A sticky solution: IWES tackles the challenges of manufacturing rotor blades with the Variable Glue Applicator
April 4, 2024
The longer the rotor blade, the greater the amount of adhesive required to bond the two blade shells together. Rotor blade manufacturers currently require around one tonne of adhesive for a rotor blade that is around 80 metres long, resulting in high costs. The scientists at Fraunhofer IWES have therefore utilised their experience from a decade of research into the manufacture of rotor blades and developed a solution that simplifies and improves the adhesive application process: the Variable Glue Applicator (VGA).
