Aerofoil, Blade and Tip Cooling Holes
The power generation industry must also react positively towards environmental concerns and the need to improve engine efficiencies. A key factor will be deploying the latest technology gains in aero-engine features to land-based turbines to enhance performance and emissions improvements as well as extending component lifetimes.
A major part of this will be in continuing to adapt cooling hole technology, achieved through a review of the number of cooling holes, their shape and strategic location. Therefore engine manufacturers increasingly need a reliable process that can make these holes quickly and accurately, reach hard-to-access areas of part geometry and form the holes to a complex exit profile.
Winbro offer two different solutions for the manufacture of these cooling holes – EDM or Laser. The choice of these technologies depends upon applied coatings (Ceramic or Metallic), metallurgy / productivity requirements or component/feature access.
