<p><P>PROBLEM TO BE SOLVED: To improve turbine engine performance by cooling a turbine blade. <P>SOLUTION: The turbine blade has a substantially hollow blade 110. An outer wall 133 of the blade 110 defines a chamber 120 extending in the radial direction for receiving a flow of a refrigerant, and the blade 110 has a front edge 112 extending in the upward or front direction, a rear edge 118 extending in the downstream or rear direction, a projecting suction side 114 and a recessed pressure side 116. The turbine blade is composed of a plurality of insertion objects 140-146 arranged in the chamber 120, and constituted so as to send a corresponding part of the refrigerant toward an inner surface of the outer wall 133 via a plurality of insertion object openings 50 by first receiving at least a part of the refrigerant entering the chamber 120. The insertion objects 140-146 form an inward outflow passage 150 and a central collection part passage 152 into which the inward outflow passage 150 flows. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
