Abstract
A rotary aerofoil blade is provided with closed cycle sodium cooling. The blade has a shank portion which contains a chamber which is in turn partially occupied by an air cooled core member. The core member serves to condense sodium vapor from the aerofoil portion of the blade. Gutter members within the chamber capture the condensed sodium as it is cenrifuged towards the aerofoil portion and direct it into a further chamber within the blade shank portion from when it flows into passages adjacent the external surface of the aerofoil portion. The high temperature of the aerofoil portion vaporizes the sodium which is then pumped by vapor pressure gradients back to cooled core member whereupon the cycle is repeated.
