DESIGN
  • In order to analyse turbine's performance and aerodynamic loads - a simulator based on Cascade Theory has been created.
  • The results from Axowind simulator a very close to the results produced by QBlade - a simulator program from Wind Energy Group of the Berlin Institute of Technology.
  • In the process of turbine design - Finite Element Method (PATRAN/NASTRAN) has been used, with all details of the turbine modeled.
  • As for the turbine itself - the generator was also modeled using FEM in order to calculate deflections and internal loads.
  • The stresses and strains in composite blade have been analysed as per IEC 61400-2 Part 2 "Small Wind Turbines".
  • The dynamic characteristics of the turbine have been calculated using a FEM model which also included custom-made tower. The scope of dynamic analysis included Normal Modes, Frequency Response and Rotor Dynamics (NASTRAN).
  • Campbell's diagram illustrates the normal modes which have been tuned to avoid resonance.

MANUFACTURE
  • The PSMG generator is mase using high quality materials - including aircraft-grade aluminium.
  • The windings of the generator are on a stator - while the rotor contains magnets.
  • Both struts and blades of the turbine are made using high-quality carbon/epoxy prepreg from TOHO TENAX (Japan).
  • Struts and blades are fabricated using high-pressure cure cycle and a proprietory technique.
  • After cure - composite parts are inspected for defects and conformity with the design drawings.
  • Finished parts (strut shown) are prepared for application of paint.
  • Painted parts prior to assembly are stored in dedicated racks.
  • Trial assembly of the prototype turbine allowed for fine-tuning of the assembly process.

INSTALLATION
  • The preferred method of installing the turbine is a concrete foundation with steel reinforcement bars
  • The foundation can be fabricated on-site using a contractor with experience in concrete/building industry
  • Hydraulic erection system has been custom-designed for the turbine, using hydraulic rams with 50T capacity.
  • The tower is assembled in horizontal position, followed by assembly of the generator at the top end of the tower.
  • The struts and the blades are assembled at the ground level, without using any specialized equipment.
  • After finished assembly - the turbine is raised to its working position using the hydraulic erection system
  • At the end of the whole process - the only missing component is the wind itself…
