摘要： A system for controlling a flow of air applied to a gas turbine shroud in an airplane engine, the air flow being adjusted by a regulator valve of position that is controlled by a first control signal calculated on the basis of a first setpoint value corresponding to predetermined clearance between the rotor and the turbine shroud. The system further comprises means for calculating at least one second control signal based on a second setpoint value different from the first value representative of clearance in the turbine, and selector means for-selecting the second control signal to control the regulator valve in response to one or more engine parameters. With such a system, it is possible to control the air flow applied to the shroud in application of a plurality of control logic systems.

摘要： A hollow turbine blade equipped with a cooling system comprises a pair of internal partitions connected to the intrados and extrados walls of the blade and dividing the interior of the blade into at least one internal cavity extending from the root end to the tip end of the blade, a median partition connected to the two internal partitions to divide the cavity defined between the two internal partitions into two half-cavities, the median partition leaving an aperture at or near one end of the blade to establish communication between the two half-cavities, air inlet holes opening into the half-cavity on the intrados side of the median partition at or near the other end of the blade, air flow disturbing regions disposed on at least part of the internal face of the intrados wall opposite the median partition, and air outlet holes provided in the extrados wall opposite the median partition. Preferably each half-cavity is divided into two passages by half-partitions extending between the median partition and the intrados and extrados walls from root to tip of the blade.
