A fluid cooled blade or vane for use in a gas turbine or like apparatus is disclosed herein. The blade or vane includes an elongated open ended skin of predetermined cross-sectional configuration, a number of spaced cooling tubes located within and extending in the elongated direction of the open ended skin, a reinforcement spar disposed within the skin along with tubes, and solid material, preferably copper, filling the elongated skin around the tubes and spar. A specific method of making the blade or vane just described is also disclosed and includes initially providing the elongated skin as a preform. The cooling tubes and spar are disposed within the preform in their intended positions. Thereafter, the filling material while being maintained in a molten liquid state is caused to flow into the remaining space within the preform around the tubes and reinforcement spar. At the same time, this molten material is prevented from entering the tubes. Thereafter, the molten material solidifies within the preform so as to hold the cooling tubes and reinforcement spar in place.
