Abstract
A strut for mounting an engine in an aircraft includes a first member and a second member. A friction material is coupled to a surface of the first member and is positioned between the first member and the second member. At least one attachment couples the first member, the second member, and the friction material. A biasing mechanism is associated with the at least one attachment. A biasing force of the biasing mechanism biases the second member into engagement with the frictional material to create a static frictional load between the first member and the second member.
Claims15
A strut for mounting an engine in an aircraft comprising:
- a first member defining a cavity;
- a second member;
- at least one friction material coupled to a surface of the first member, the at least one friction material being positioned between the first member and the second member, wherein the at least one frictional material and the second member are disposed within the cavity defined by the first member;
- at least one attachment coupling the first member, second member, and the at least one friction material;
- and
- a biasing mechanism associated with the at least one attachment, wherein a biasing force of the biasing mechanism biases the second member into engagement with the at least one frictional material to create a static frictional load between the first and second members.
An aircraft comprising:
- an engine;
- a strut for mounting the engine to an adjacent component of the aircraft, the strut having a first member and a second member, wherein the strut is operable in one of a plurality of modes in response to a load applied to at least one of the first member and the second member, and in a first mode of the plurality of modes, the strut absorbs vibrations from the engine between the first member and the second member.
