Hyperstatic truss comprising connecting rods

摘要

A hyperstatic truss including connecting rods, used for suspension of a first ring, forming part of an engine case, inside a second ring concentric to the first ring, the connecting rods being secured at one end to the first ring and at the other end to the second ring. The tensile stiffness of the connecting rods is greater than the compressive stiffness thereof. The truss for example can be used for suspension of a ducted-fan turbine engine with an elongate bypass duct.

主权项

1. A hyperstatic truss comprising:
connecting rods applied to suspending a first ring, that forms part of an engine casing, inside a second ring concentric with the first ring, the connecting rods being secured by a first end to the first ring and by a second end to the second ring, wherein a tensile strength of the connecting rods is higher than a compressive strength of the connecting rods, said connecting rods comprising a set of one or more parts configured to transmit compressive and tensile loads between the ends of said connecting rods, and one or more other parts configured to cooperate with at least one part of said set of parts to transmit only tensile loads between the first a second ends of said connecting rods.
