Title:
CERAMIC TURBINE ROTOR
Document Type and Number:
Japanese Patent JP3176190
Kind Code:
B2
Abstract:
PURPOSE: To improve transient responsiveness of a gas turbine engine or the like, by eliminating inner defectives causing breaking from a large-sized radial ceramic turbine rotor which has a plurality of blades on its outer periphery, providing resistivity against high centrifugal force, reducing and averag thermal stress at high temperature and high speed rotation.
CONSTITUTION: A cylindrical disc 2 has a plurality of blades 3 on its outer periphery, and a thickness 5 which is 0.05 to 0.1 times of a maximum outer diameter 4 formed by orbit of the blades 3 rotating around a rotational center. An end face of the disc 2 is provided with at least one of a nose 6 and a back face 7. Especially, the back face 7 having a projection 9 connected to a rotary shaft is preferred and integrated with the disc 2. The disc 2 has a hollow space 8 thereinside formed with no opening.
