Abstract
A gas turbine engine blade comprises a dovetail, a shank extending from the dovetail, an airfoil, and a platform between the shank and the airfoil. The platform comprises a side wall extending between an upstream side and a downstream side of the platform. A first pin channel extends from the upstream side of the sidewall and a second pin channel, co-axial with the first pin channel, extends from the downstream side of the sidewall. The first channel includes a radial notch at the upstream longitudinal end of the first pin channel.

A gas turbine engine blade, comprising:
- a dovetail;
- a shank extending from the dovetail;
- an airfoil;
- and
- a platform between the shank and the airfoil, the platform comprising a side wall extending between an upstream side and a downstream side of the platform, wherein a first pin channel extends from the upstream side of the sidewall and a second pin channel, co-axial with the first pin channel, extends from the downstream side of the sidewall, where the first channel includes a radial notch at the upstream longitudinal end of the first pin channel.
A gas turbine engine blade assemblage, comprising:
- a dovetail;
- a shank extending from the dovetail;
- an airfoil;
- a platform between the shank and the airfoil, the platform comprising a side wall extending between an upstream side and a downstream side of the platform, wherein a first pin channel extends from the upstream side of the sidewall and a second pin channel, co-axial with the first pin channel, extends from the downstream side of the sidewall, where the first channel includes a radial notch at the upstream longitudinal end of the first pin channel;
