This PR fixes a small bug in the blade metal temperature calculation when turbine cooling heat exchangers are used. The previous version ignored the effect of the heat exchanger when calculating the metal temperature for a given cooling fraction. The effect was accounted for later, so this issue only affected the metal temperature output and not the engine performance.
