Abstract
A hollow turbine guide blade or vane is provided with three separate cooling circuits formed by virtue of two radial partitions extending the length of the blade within the cavity bounded by the outer wall of the blade and dividing the cavity into first, second and third ducts, and radial passages extending the length of the blade within the outer wall in the vicinity of the leading edge and the extrados face of the blade. The leading edge area is cooled by air flowing through the radial passages in this area and then through the first duct. The extrados face area is cooled by air flowing through the radial passages in this area and then through the second duct. The intrados face area is cooled by air flowing through the third duct. The first duct communicates with the outside of the blade through slits opening in the extrados face near the leading edge of the blade, and the second and third ducts each communicate with the outside of the blade through slits opening in the intrados face in the vicinity of the trailing edge.
