New type of wind turbine with composite rotor blade
- Cracow Univ. of Technology, Krakow (Poland)
During the last three years a new type of a wind turbine has been designed and tested in Division of Machine Design at Cracow University of Technology. The wind turbine consists of four main units: (1) rotor with two blades, each of them having an aerodynamically formed surface made of a laminated composite material bordered by a metallic frame; (2) directing system consisting of one rotor unit which drives blades about their own axis and controls the orientation of the turbine towards the wind; (3) supporting and transmissing system; and (4) foundation consisting of typical reinforced concrete plates fastened together, convenient to transport. The paper presents the method describing simulation of motion of the turbine. Such an approach gives one the possibility to analyze the maximum load acting in the vicinity of the blade and the load response of the elements of the turbine. A certain useful technique is demonstrated which can be applied to determine the load distribution. It is used to find e.g. the optimal fastening of internal metallic frame of the rotor blade. Specific and important advantages of the new type of engine are summarized in the final remarks as follows: perfect static and dynamic balancing, nice geometric shape of rotor which can be made of typical materials, low mass and cost per unit, typical technology of elements, easy mounting and dismounting. Several designing and technological solutions are illustrated in graphs and drawings.
