Test FLEXTEETER. Volume 1: Main body of the report

Technical Report:

Abstract

A two-bladed rotor (FLEXTEETER) equipped with an elastomeric teeter, flexible beams and passive control tips was tested at the 25m Horizontal Axis Wind Turbine (HAWT) rotor test facility at the Netherlands Energy Research Foundation (ECN) in Petten. This project formed the second and final field test within the framework of the FLEXHAT program, in which technology for the next generation of wind turbines is developed. The objectives of the title test were to demonstrate stable and safe operation of the flexible rotor and to confirm the predicted load reduction by measurements. In this volume results of field tests with the FLEXTEETER as well as the stiff rotor 20-WPX-PRT1 are surveyed and if applicable compared with results of the test of 20-WPX-THR rotor blades. The main part of this report concerns a description of the measurement program. In the second and third volume test reports concerning several parts of the FLEXTEETER test project are given in the form of appendices A-F and G-L. 17 figs., 5 tabs., 17 refs.
