<p>A conventional gas turbine blade using a steam cooling system, in which high-pressure steam is supplied to an inner portion of the blade to cool the blade therewith and recover thermal energy, has been proposed but has a problem to be solved concerning its strength. A gas turbine blade capable of solving this problem free from the strength problem and sufficiently resistant to a flow of the high-pressure steam, wherein a cooling medium flow passage extending in the lengthwise direction of the blade is formed in the interior thereof, reinforcing ribs connecting front and rear walls of the blade together and extending in the direction of a flow of the cooling medium being provided in the cooling medium flow passage, whereby the strength of the blade is secured without hampering the flow of the cooling medium.</p> |
