Abstract
A ceramic regenerator core of cylindrical configuration adapted to be mounted in a gas turbine engine for rotation about its geometric axis comprising a honeycomb matrix that accommodates the flow of hot exhaust gases in an axial direction through one segment of the matrix and the flow of cool intake air through another segment of the matrix as the core is rotated, the matrix passages being formed by contiguous parallelogram shape passages, the principal diagonal for each passage generally parallel to the direction of maximum stress in the core whereby a maximum degree of thermal stress resistance is achieved thus reducing the possibility of fracture of the matrix material.
