Turbine Blade Profile topics include: Turbine, impulse and reaction blade profiles, blade entrance and exit angles, losses and geometry of impulse blade profiles and passages, gauging and pitch and free and forced vertex. Steam turbine blades are critical components in power plants. They convert the linear motion of high temperature and high pressure steam into a rotary motion of the turbine shaft.  Here are some things to know about turbine blade profiles: The leading edge is where the gas flow enters the profile while the trailing edge is where the gas leaves the profile. The specific... Show more
