Abstract: The present disclosure relates to a blade and a gas turbine, and a blade may include: a body part; an injection hole comprising a communication part connected to an internal flow passage formed inside the body part; and an extension connecting the communication part and a surface of the blade to each other and having a width gradually increasing from the communication part the surface of the blade and configured to inject a cooling fluid to the surface of the blade; and an injection guide means disposed in the extension and configured to uniformly inject the cooling fluid in an expanding manner so as to form a cooling film on the surface of the blade. According to the present disclosure, it is possible to form the cooling film wider on the surface of the blade, by preventing a problem of a separation that occurs during when the cooling fluid flows through materialization of the uniform injection of the cooling fluid to the surface of the blade.

Abstract: The present disclosure relates to a system and method for adjusting control sensitivity based on optimal search. According to the present disclosure, stable control convergence can be achieved without excessively shortening the lifespan of a target device by moving a target device only when there is a control gain larger than or equal to a preset reference value. This occurs during continuous control of the target device through the system for adjusting a control sensitivity based on optimal search, which adjusts the sensitivity of the continuous control based on optimal search.
