Abstract
In the design of a gas turbine as a power plant, the turbine manufacturer always redesigns for improvements from the previous design (continuous improvement). In this research discusses the redesign of a gas turbine for the S-20 power plant model. The use of software that has been used to get more tangible from the basic theory of gas turbine blades in this case is the average speed triangle. When discussing the beginning, middle, and end of profiles and blade hubs, meridian lines, and edges. It can be seen the change in gas flow on stator-rotor which is then absorbed by the kinetic energy of the gas that hits the blade to produce rotary energy. The results of this design produce as much power as 1 level. Producing more optimal blade shapes with NACA Numbers and Modeling using Computational Fluid Dynamic Solver (CFD).
