Abstract
The present invention relates to a bleed system for use in a gas turbine engine. The bleed system comprises a plurality of blades with each of the blades having an airfoil member and a platform structure. The bleed system further has at least one interblade passage formed by adjacent ones of the airfoil members and an inner endwall formed by the platform structures. A bleed hole is located in the at least one interblade passage for extracting a portion of a fluid passing therethrough. The bleed positioning within the stator passage, both axially and circumferentially, is selected for optimum balance of static pressure and tangential velocity.
