Abstract
A clamp for securing a component to an isogrid case of a gas turbine engine includes a top having an attachment feature for coupling the clamp to the component. The clamp further includes a bottom. The clamp further includes two sides extending from the top towards the bottom, each of the two sides being thicker at the bottom than at the top, and the two sides defining a shaped slot closer to the bottom than the top for receiving a rib of the isogrid case.
Claims16
A clamp for securing a component to an isogrid case of a gas turbine engine, the clamp comprising:
- a top;
- an attachment feature disposed at the top, wherein the attachment feature is for coupling the clamp to the component, wherein the attachment feature includes a threaded post coupled to the clamp;
- a bottom;
- and
- two sides extending from the top towards the bottom, each of the two sides being thicker at the bottom than at the top, and the two sides defining a shaped slot closer to the bottom than the top for receiving a rib of the isogrid case, the rib having a vertical portion extending at a right angle from a surface of the isogrid case and a horizontal portion extending in a direction parallel to the surface, a right angle being formed between a vertical outer surface of the vertical portion and a horizontal outer surface of the horizontal portion, the shaped slot having a vertical portion having a corresponding shape and dimension of the vertical portion of the rib and a horizontal portion having a corresponding shape and dimension as the horizontal portion of the rib;
- wherein each of the two sides defines a lightening hole closer to the bottom than the top and configured to reduce a total weight of the clamp, wherein the lightening holes are disposed between a central opening and the bottom, wherein the central opening is defined between the two sides.
A clamp for securing a component to an isogrid case of a gas turbine engine, the clamp comprising:
- a top having an attachment feature for coupling the clamp to the component;
- a bottom;
- and
- two sides extending from the top towards the bottom, each of the two sides being thicker at the bottom than at the top, and the two sides defining a shaped slot closer to the bottom than the top for receiving a rib of the isogrid case, the rib having a vertical portion extending at a right angle from a surface of the isogrid case and a horizontal portion extending in a direction parallel to the surface, a right angle being formed between a vertical outer surface of the vertical portion and a horizontal outer surface of the horizontal portion, the shaped slot having a vertical portion having a corresponding shape and dimension of the vertical portion of the rib and a horizontal portion having a corresponding shape and dimension as the horizontal portion of the rib, and each of the two sides defining a boss for receiving a fastener,
- wherein each of the two sides defines a lightening hole closer to the bottom than the top and configured to reduce a total weight of the clamp, wherein the lightening holes are disposed between a central opening and the bottom, wherein the central opening is defined between the two sides.
A system for securing components to a gas turbine engine, the system comprising:
- an isogrid case having a rib and configured to be coupled to the gas turbine engine;
- and
- a clamp for securing a component to the isogrid case and having:
- a top having an attachment feature for coupling the clamp to the component,
- a bottom, and
- two sides extending from the top towards the bottom, each of the two sides being thicker at the bottom than at the top, and the two sides defining a shaped slot closer to the bottom than the top for receiving the rib of the isogrid case to couple the clamp to the isogrid case, the rib having a vertical portion extending at a right angle from a surface of the isogrid case and a horizontal portion extending in a direction parallel to the surface, a right angle being formed between a vertical outer surface of the vertical portion and a horizontal outer surface of the horizontal portion, the shaped slot having a vertical portion having a corresponding shape and dimension of the vertical portion of the rib and a horizontal portion having a corresponding shape and dimension as the horizontal portion of the rib,
- wherein each of the two sides defines a lightening hole closer to the bottom than the top and configured to reduce a total weight of the clamp, wherein the lightening holes are disposed between a central opening and the bottom, wherein the central opening is defined between the two sides.
