Abstract
A gas turbine moving blade platform having a simplified cooling structure for effecting uniform cooling of the platform. The platform (,) includes cavities (,) and an impingement plate (,) provided below the cavities (,). A cooling hole (,) communicates with cavity (,), cooling hole (,) communicated with cavity (,) and cooling holes (,) communicate with cavity (,) and all of the cooling holes pass through the platform (,) at an inclined angle. Cooling air (,) flows into the cavities (,) through holes (,) in the impingement plate (,) for effecting impingement cooling of platform (,) plane portion. The cooling air (,) further flows through the cooling holes (,) to blow outside angularly upward for cooling peripheral portions of the platform. Thus, the platform is cooled uniformly, no lengthy and complicated cooling passage is provided, and workability is enhanced.
