Airfoil assembly

An airfoil assembly for a turbine engine defining an axial direction, a radial direction, and a circumferential direction, the airfoil assembly comprising:

• a first airfoil defining a first end along the radial direction;
• a first hub disposed on the first end of the first airfoil and comprising a first extension member extending at least partially in the radial direction;
• a second airfoil adjacent to the first airfoil, the second airfoil defining a first end along the radial direction;
• a second hub disposed on the first end of the second airfoil and comprising a second extension member extending at least partially in the radial direction;
• a circumferential bias assembly operable with the first extension member, the second extension member, or both for exerting a circumferential force on the first extension member, the second extension member, or both, wherein the circumferential bias assembly is a first shroud assembly, and wherein the first shroud assembly comprises a first spring member coupled to the first extension member, positioned adjacent to the first extension member, or both;
• and
• a second circumferential bias assembly configured as a second shroud assembly,
• wherein the second shroud assembly comprises a second spring member coupled to the second extension member, positioned adjacent to the second extension member, or both, and
• wherein the first spring member is configured to exert a circumferential load against the second hub.

• a circumferential bias assembly operable with the first extension member and the second extension member for exerting a circumferential force on at least one of the first extension member or the second extension member, wherein the circumferential bias assembly is operable with the first extension member to exert a first circumferential force on the first extension member in a first direction,
• wherein the circumferential bias assembly is operable with the second extension member to exert a second circumferential force on the second extension member in a second direction, and
• wherein the first direction is opposite of the second direction.
