Abstract
A blade seal comprising: a base; a tip; a first part formed from an elastomeric material which extends continuously from the base to the tip; and a second part formed from an elastomeric material mixed with conductive filler which extends continuously from the base to the tip. The blade seal is manufactured by compressing the first and second parts together; and curing one or both of the parts as they are compressed together.
Claims11
A blade seal comprising:
- a base;
- a tip;
- a first part formed from a non-conductive material, wherein said non-conductive material is elastomeric which extends continuously from the base to the tip;
- a second part formed from a conductive material, wherein said conductive material is elastomeric mixed with conductive filler which extends continuously from the base to the tip;
- wherein a path of highest conductivity across the sealing member is provided by the conductive filler within the second part and not the first part;
- and,
- wherein the first part is arranged to engage a component at the tip of the blade seal to form an environmental seal with the component, and the second part is arranged to engage the component at the tip of the blade seal to form an electrical connection with the component.
