Aviation gas turbines are making more use of blades internally cooled by air taken from the cycle. Such blades reduce temperatures ahead of the turbine, increasing specific power and decreasing fuel flow, but involve energy losses and decrease of efficiency. A study is reported of one construction of a moving blade cooled by forced convection, in which the cooling air escapes from the blade into the interior of the turbine.
