Turbine blade and turbine
View Patent ↗The pressure distribution curve of the blade suction-side surface excluding the leading edge portion and the trailing edge portion drops in two stages in the area from the leading edge to the minimum pressure point.
1. A turbine moving blade, wherein a profile of said moving blade is formed so that a maximum blade load position at each height position is located at a blade trailing edge side in an area from a blade root thereof to a blade tip thereof, and wherein when a blade surface axial location of the maximum blade load position with respect to a leading edge is denoted as Xn and a blade axial chord is denoted as Cax, a normalized value Xn/Cax at the maximum blade load position at the blade root is around 0.9.
2. A turbine moving blade, wherein a profile of said moving blade is formed so that a maximum blade load position at each height position is located at a blade trailing edge side in an area from a blade root thereof to a blade tip thereof, and the profile of said turbine moving blade is formed so that the maximum blade load position at the blade root is located at the blade trailing edge side and the maximum blade load position moves to a blade leading edge side as an area moves from the blade root toward the blade tip, and wherein when a blade surface axial location of the maximum blade load position with respect to a leading edge is denoted as Xn and a blade axial chord is denoted as Cax, a normalized value Xn/Cax at the maximum blade load position at the blade root is around 0.9.
