Jul 22 2016 the larger the better but a good rule of thumb is to size the radius to 130 of the radius of the cutter or more the red portion of the image on the far right shows the additional cutter engagement at a corner sized to the radius of the cutter while the other image shows how much less engagement is required by sizing the corner to 130 of the cutter radius
The howden 33m turbine used this basic approach but is known to have had root problems this choice of material system and root type is not enough to ensure success by itself as in other parts of the wind turbine rotor appropriate engineering design practice and
27 illustrates this type pitting on a throughhardened gear figure 28 shows destructive pitting of a surface hardened gear destructive pitting usually results from surface overload conditions that are not alleviated by initial pitting if tooth surface hardness is within specified values system overloads are usually the cause of such pitting
Design which despite extensive research and development has so far been unable to compete with the modern hawt design although recent developments 23 could see a resurgence of this rotor type due to its efficiency and ease of control the aerofoil three bladed hawt no 6 has become the wind
