Abstract

An antenna cover of an aircraft including: a cover that protects an antenna mounted in the aircraft; a conductive layer having conductivity that is provided on an outer side of the cover; and a rain erosion boot that covers one region of the conductive layer, wherein the rain erosion boot includes a main material having an insulating property, is given conductivity, and is grounded to an airframe via the conductive layer, or the rain erosion boot includes a main material having an insulating property, and is given hydrophilicity.

Claims (65)

1. An antenna cover of an aircraft comprising:

a cover that protects an antenna mounted in the aircraft;

a conductive layer having conductivity that is provided on an outer side of the cover; and

a rain erosion boot that covers one region of the conductive layer, wherein the rain erosion boot does not entirely cover the conductive layer,

wherein the rain erosion boot includes a main material having an insulating property, is given conductivity, and is grounded to an airframe via the conductive layer, or

the rain erosion boot includes a main material having an insulating property, and is given hydrophilicity.

2. The antenna cover of an aircraft according to claim 1 , wherein the rain erosion boot covers a forward-most portion of the cover.

3. An antenna cover of an aircraft comprising:

a cover that protects an antenna mounted in the aircraft;

a conductive layer having conductivity that is provided on an outer side of the cover; and

a rain erosion boot that covers one region of the conductive layer,

wherein the rain erosion boot includes a main material having an insulating property, is given conductivity, and is grounded to an airframe via the conductive layer,

wherein the rain erosion boot comprises:

conductive particles mixed into the main material that give the rain erosion boot conductivity; or

a conductive filler mixed into the main material that gives the rain erosion boot conductivity.

4. An antenna cover of an aircraft comprising:

a cover that protects an antenna mounted in the aircraft;

a conductive layer having conductivity that is provided on an outer side of the cover; and

a rain erosion boot that covers one region of the conductive layer,

wherein the rain erosion boot includes a main material having an insulating property, and is given hydrophilicity, and

wherein the rain erosion boot comprises a surfacant mixed into the main material that gives the rain erosion boot hydrophilicity.

5. A member cover of an aircraft comprising:

a cover that protects a member mounted in the aircraft; and

a rain erosion boot that covers an outer side of the cover,

wherein the rain erosion boot includes a main material having an insulating property, and is given conductivity,

wherein the member is a lighting device emitting light,

wherein the light emitted from the lighting device is transmitted through the cover, and

wherein the rain erosion boot comprises:

conductive particles mixed into the main material that give the rain erosion boot conductivity; or

a conductive filler mixed into the main material that gives the rain erosion boot conductivity.

6. A member cover of an aircraft comprising:

a cover that protects a member mounted in the aircraft; and

a rain erosion boot that covers an outer side of the cover,

wherein the rain erosion boot includes a main material having an insulating property, and is given hydrophilicity,

wherein the member is a lighting device emitting light,

wherein the light emitted from the lighting device is transmitted through the cover, and

wherein the rain erosion boot comprises a surfacant mixed into the main material that gives the rain erosion boot hydrophilicity.

7. The antenna cover of an aircraft according to claim 3 ,

wherein surface resistivity of the rain erosion boot is 0.5 MΩ/sq to 15 MΩ/sq.

8. The antenna cover of an aircraft according to claim 3 ,

wherein the conductive layer has

a portion that is covered with the rain erosion boot, and

a portion where a lightning protection member through which a current of lightning striking the cover flows is arranged, and

the conductive layer is grounded to the airframe via a fastener that penetrates the conductive layer in a thickness direction and fastens the lightning protection member to the cover.

9. The antenna cover of an aircraft according to claim 8 ,

wherein the lightning protection member is a strip made of metal.

10. The antenna cover of an aircraft according to claim 1 ,

wherein the antenna is mounted at a front end of the airframe,

the cover is formed in a bowl shape so as to cover the antenna from a front side,

the conductive layer is applied to an entire outer surface of the cover, and

the rain erosion boot is provided in a predetermined region located at a front end of the cover.

11. The antenna cover of an aircraft according to claim 1 ,

wherein the rain erosion boot comprises a resin as the main material.

12. The antenna cover of an aircraft according to claim 11 ,

wherein the rain erosion boot is formed of a plurality of polymer layers having different characteristics.

13. The antenna cover of an aircraft according to claim 1 ,

wherein the conductive layer has a thickness of 0.31 to 0.36 mm, and the rain erosion boot has a thickness of 0.1 mm to 1 mm.

14. The antenna cover of an aircraft according to claim 13 ,

wherein the rain erosion boot has a thickness of 0.1 mm to 0.3 mm.

15. An aircraft comprising the antenna cover according to claim 1 .

16. An aircraft comprising the member cover according to claim 3 .

17. An aircraft comprising the member cover according to claim 4 .

18. An aircraft comprising the member cover according to claim 5 .

19. The antenna cover of an aircraft according to claim 5 ,

wherein surface resistivity of the rain erosion boot is 0.5 MΩ/sq to 15 MΩ/sq.
