Turbine rotor blade for gas turbine stage with nominal blade profile defined within 10%to90% of its height, with shape variations dependent upon load and temperature

摘要

The rotor blade has a blade body, with a nominal profile within an area of 10% to 90% of its height, which corresponds to mainly to cartesian coordinates. These are a distance in inches, to a plane extending at right angles the rotary axis of the turbine; and distances in inches, which, when connected by smooth continuous curves, each define a profile cross section for each blade body. The profile cross sections join smoothly with each other. The blade is part of a second turbine stage.
