Asymmetric blade locking apparatus

A turbine engine comprising:

• a circumferential row of platforms;
• blades extending radially outward from the platforms;
• dovetails extending radially inward from the platforms, the dovetails including a first dovetail and a second dovetail adjacent the first dovetail;
• and
• a locking lug including an orifice to receive a screw, the locking lug including a first portion and a second portion, wherein the first portion spans from the orifice to a first end of the locking lug in a circumferential direction, wherein the second portion spans from the orifice to a second end of the locking lug in the circumferential direction, wherein the first end contacts the first dovetail, wherein the second end contacts the second dovetail, and wherein the first portion of the locking lug spans a greater distance than the second portion in the circumferential direction, wherein the second portion spans a greater distance than the first portion in an axial direction defined by the turbine engine.

An apparatus comprising:

• a first platform including a first inner radial surface, a first outer radial surface, and a first circumferential edge, a first dovetail extending from the first inner radial surface, a first blade extending from the first outer radial surface;
• a second platform including a second inner radial surface, a second outer radial surface, and a second circumferential edge, the second circumferential edge adjacent the first circumferential edge, a second dovetail extending from the second inner radial surface, a second blade extending from the second outer radial surface;
• and
• a locking lug including a radial hole to receive a screw to be positioned between the first circumferential edge and the second circumferential edge in a circumferential direction, wherein the locking lug contacts the first dovetail and the second dovetail, wherein an engagement between the locking lug and the first dovetail is different from an engagement between the locking lug and the second dovetail, wherein the locking lug includes a first portion extending from the radial hole to a first circumferential surface of the locking lug that contacts the first dovetail, wherein the locking lug includes a second portion extending from the radial hole to a second circumferential surface of the locking lug that contacts the second dovetail, and wherein the first portion spans a greater distance in the circumferential direction than the second portion, wherein the first portion of the locking lug has a reduced mass per unit of circumferential span relative to the second portion.
