ABSTRACT:
A combined impingement effusion method comprises brazing or welding a waffled impingement plate to the cold back-side surface of component having effusion holes there through. The impingement plate comprises a plurality of small baffle cells to relieve the thermal stresses between the impingement plate and the component. By rigidly attaching the impingement plate, the cooling flow leakage associated with the seals of floating plates is avoided.
