  • Turbomachine including a device for supplying pressurized gas
    Patent number: 6334755
    Abstract: The invention provides a turbomachine including a device for supplying pressurized gas, the gas being bled from the compressor of the turbomachine via a bleed orifice and cooled in a cooling cavity disposed within the compressor rotor upstream of the bleed orifice. This arrangement has the effect of cooling the bled gas by heat transfer through the outer wall of the compressor rotor to the gas stream which is being compressed by the compressor upstream of the bleed orifice, and has the result of reducing the drop in the performance of the compressor as a result of the gas being bled off.

  • Process for the manufacture of thin ceramic cores for use in precision casting
    Patent number: 6286582
    Abstract: A process for the manufacture of a thin ceramic core involves casting a band of uniform thickness on a support from a solution of a ceramic material based on silica and zircon in a binder, drying the band, shaping the band in a mold and carrying out preheating and pressing of the band in the mold, baking the component thus obtained in a ceramic preform, and then carrying out an impregnation. The thin core obtained can be assembled together with another thin core and/or on a conventional thick central core, and can be used in precision casting such as in the production of turbine blades.
