Patent ID: 8167552

Claim:
A locking member of a device for fastening ring sectors to an aircraft turbine engine casing, said member extending in a circumferential direction between a first circumferential end and a second circumferential end, said member having, in a cross-section along a plane perpendicular to said circumferential direction, first and second clamping branches connected together at rear ends thereof, by first and second curved joining portions, respectively, by a connecting branch extending substantially parallel to a general spacing direction of the two clamping branches, front ends of the two clamping branches being intended to press between them at least one ring sector against at least one casing element, said member is such that, in said cross-section: said first clamping branch has a first inside surface; said second clamping branch has a second inside surface; said connecting branch has an inside connecting surface; said first curved joining portion has a first inside joining surface having a mean radius Rm 1 ; and said second curved joining portion has a second inside joining surface having a mean radius Rm 2 , said first curved joining portion being defined by a first angular sector, which is defined by a normal to said first inside surface at a connecting point with said first inside joining surface, and by a normal to said inside connecting surface at a connecting point with said first inside joining surface, and said second curved joining portion being defined by a second angular sector which is defined by a normal to said second inside surface at a connecting point with said second inside joining surface, and by a normal to said inside connecting surface at a connecting point with said second inside joining surface, in a direction of a bisectrix of the first angular sector, said first curving joining portion having a thickness E 1 , and, in a direction of a bisectrix of the second angular sector, said second curved joining portion having a thickness E 2 , wherein the thickness E 1 is strictly smaller than thickness E 2 , and the mean radius Rm 1 is strictly smaller than mean radius Rm 2 .
