Abstract

A bond fixture includes a first fixture having a heater and a plurality of clamps. Each of the plurality of clamps includes a first member and a second member rotatable between a first position and a second position. A second fixture includes a root end lift translatable vertically between a retracted position and an extended position and a root end clamp translatable along a horizontal axis. The root end clamp is configured to cooperate with the root end.

First claim

What is claimed is:

1. A bond fixture comprising:
a first fixture including:
a plurality of clamps, each of said plurality of clamps including a first member and a second member being rotatable between a first position and a second position;
a plurality of pads configured to contact a component receivable between the first member and the second member, each of the plurality of pads being associated with one of the plurality of clamps, and being movable relative to at least one of the first member and the second member thereof; and
a heater; and

a second fixture including:
a root end lift translatable vertically between a retracted position and an extended position; and
a root end clamp translatable along a horizontal axis, the root end clamp being configured to cooperate with an end of the component.

2. The bond fixture according to claim 1 , wherein the heater includes a plurality of regions, and heat output at each of the plurality of regions is substantially identical.

3. The bond fixture according to claim 1 , wherein the heater includes a plurality of regions, and heat output from at least one of the plurality of regions varies.

4. The bond fixture according to claim 1 , wherein the plurality of clamps are equidistantly spaced.

5. The bond fixture according to claim 1 , wherein each of the first member and the second member of each of the plurality of clamps includes a pad configured to contact a component receivable between the first member and the second member.

6. The bond fixture according to claim 5 , wherein the component is a rotor blade.

7. The bond fixture according to claim 1 , wherein at least one of the first members of each of the plurality of clamps and the second members of each of the plurality of clamps is configured to move in unison.

8. A bond fixture comprising:
a first fixture including:
a plurality of clamps, each of said plurality of clamps including a first member and a second member being rotatable between a first position and a second position;
a plurality of pads configured to contact a component receivable between the first member and the second member, each of the plurality of pads being associated with one of the plurality of clamps, and being movable relative to at least one of the first member and the second member thereof; and
a heater; and

a second fixture including:
a root end lift translatable vertically between a retracted position and an extended position; and
a root end clamp translatable along a horizontal axis, the root end clamp being configured to cooperate with an end of the component;

 wherein the bond fixture is operable to install a sheath assembly laminate to a rotor blade via application of localized and constant heat and pressure to the sheath assembly laminate.
