Abstract
A turbomachine includes a plurality of blades, and each blade has an airfoil. The turbomachine includes opposing walls that define a pathway into which a fluid flow is receivable to flow through the pathway. A throat distribution is measured at a narrowest region in the pathway between adjacent blades, at which adjacent blades extend across the pathway between the opposing walls to aerodynamically interact with the fluid flow. The airfoil defines the throat distribution, and the throat distribution reduces aerodynamic loss and improves aerodynamic loading on each airfoil.

A turbomachine comprising a plurality of blades, each blade comprising an airfoil, the turbomachine comprising:
- opposing walls defining a pathway into which a fluid flow is receivable to flow through the pathway, a throat distribution is measured at a narrowest region in the pathway between adjacent blades, at which adjacent blades extend across the pathway between the opposing walls to aerodynamically interact with the fluid flow;
- and
- the airfoil defining the throat distribution, the throat distribution reducing aerodynamic loss and improving aerodynamic loading on each airfoil, the throat distribution, as defined by a trailing edge of the blade, extending generally linearly from a throat/throat mid-span value of about 82% at about 5% span to a throat/throat mid-span value of about 115% at about 90% span, a throat/throat mid-span value of about 110% at about 95% span, and a throat/throat mid-span value of about 82.5% at about 100% span, and wherein the span at 0% is at a radially inner portion of the airfoil and a span at 100% is at a radially outer portion of the airfoil, and the throat/throat mid-span value is 100% at about 50% to 55% span.
A blade having an airfoil, the blade configured for use with a turbomachine, the airfoil comprising:
- a throat distribution measured at a narrowest region in a pathway between adjacent blades, at which adjacent blades extend across the pathway between opposing walls to aerodynamically interact with a fluid flow;
- and
- the airfoil defining the throat distribution, the throat distribution reducing aerodynamic loss and improving aerodynamic loading on the airfoil, the throat distribution, as defined by a trailing edge of the airfoil, extending generally linearly from a throat/throat mid-span value of about 82% at about 5% span to a throat/throat mid-span value of about 115% at about 90% span, a throat/throat mid-span value of about 110% at about 95% span, and a throat/throat mid-span value of about 82.5% at about 100% span;
- and wherein the span at 0% is at a radially inner portion of the airfoil and a span at 100% is at a radially outer portion of the airfoil, and the throat/throat mid-span value is 100% at about 50% to 55% span.
