Turbines are high-precision devices that convert fluid pressure and velocity into rotational energy for application in such areas as jet and marine propulsion, electrical power supply, etc.

There are several types of turbines, including steam turbines that extract thermal energy from pressurized steam, and gas turbines that extract energy from a flow of combustion gas.

The wings of a turbine are called “turbine blades,” which work in the same way as the wings of windmills. These blades are an important component that determines the performance of the turbine.

Recent improvements in the efficiency of the turbine blade include the development of shrouded 3-dimensional blades and the employment of specialized material for high temperature, pressure and rotation
