<p>The present invention relates to an airfoil for a turbine. The airfoil for a turbine comprises: a body part; a main flow passage part formed inside the body part to allow compressed air to flow; a connection flow passage part connected to the main flow passage part to have a cross-sectional area smaller than the same of the main flow passage part; a collision part which is formed inside the body part, is connected to the connection flow passage part to be expanded, and has a side to collide with the compressed air injected from the connection flow passage part; a guide flow passage part formed inside the body part and connected to the collision part to guide the compressed air inside the collision part to the surface of the body part; and a pin part installed in the guide flow passage part.</p> |
