Tip member for blade structure and related method to form turbomachine component

A turbomachine component comprising:

• a blade structure having a root, a radially outboard end positioned opposite the root, and an airfoil portion extending between the root and the radially outboard end;
• a post coupled to the radially outboard end of the blade structure, and extending at least partially radially outward relative to the blade structure;
• and
• a tip member positioned on the blade structure, wherein the tip member includes:
• a first surface engaging the radially outboard end of the blade structure;
• a second surface positioned opposite the first surface,
• at least one perimeter sidewall positioned between the first and second surfaces, wherein the at least one perimeter sidewall of the tip member and the airfoil portion of the blade structure form a single airfoil profile, and
• an opening passing through the tip member from the first surface to the second surface, and having a single directional orientation therebetween, wherein the post is positioned within the opening of the tip member.

A method of forming a turbomachine component, the method comprising:

• providing a tip member, the tip member including:
• a first surface configured to engage an outboard end of a blade structure,
• a second surface positioned opposite the first surface,
• at least one perimeter sidewall positioned between the first and second surfaces, wherein the at least one perimeter sidewall has an airfoil cross-section, and
• an opening passing through the tip member from the first surface to the second surface, and having a single directional orientation therebetween, wherein the opening is sized to receive a post positioned on the outboard end of the blade structure;
• positioning the post of the blade structure through the opening of the tip member to mount the tip member on the outboard end of the blade structure;
• and
• mechanically coupling the second surface of the tip member to the post to form the turbomachine component.
