Abstract

There is provided a cockpit window of an aircraft and the aircraft in which an electromagnetic shield film for preventing electromagnetic noise can be reliably and easily provided at low cost. An electromagnetic shield film is provided to a window part, and a conductive film is provided between the electromagnetic shield film and an outer retainer made of a conductive material. The conductive film is connected to the electromagnetic shield film via a connecting member is provided so as to be led to an outer perimeter side of the window part along an outer perimeter part of the window part, and is electrically connected to the outer retainer. With this configuration, a film made of a conductive material is formed without a gap at a joint portion between the window part and the outer retainer. Also, the conductive film is assumed to have flexibility.

Claims

1. A cockpit window of an aircraft having an electromagnetic shield comprising:

a plurality of laminated transparent widow panels;

an inner-side inner retainer and an outer-side outer retainer provided to an outer perimeter part of the window panels, the retainers interposing the window panels and made of a conductive material;

a coupling member coupling the inner retainer and the outer retainer to each other;

a weather seal provided between the outer retainer and the window panels;

an electromagnetic shield film provided between two of the window panels that are opposed to each other and made of a conductive material;

a connecting film made of a conductive material and electrically connecting an outer perimeter part of the electromagnetic shield film and the outer retainer; and

a heater layer for anti-icing or de-fogging that is separate from the electromagnetic shield film and provided between the plurality of window panels.

2. The cockpit window of the aircraft having the electromagnetic shield according to claim 1, wherein the plurality of window panels comprise glass.

3. The cockpit window of the aircraft having the electromagnetic shield according to claim 1, wherein the connection film directly contacts the outer retainer.

4. The cockpit window of the aircraft having the electromagnetic shield according to claim 1, wherein the connection film is grounded to the outer retainer around an entire perimeter of the plurality of window panels.

5. The cockpit window of the aircraft having the electromagnetic shield according to claim 1, wherein there is no air gap between the plurality of window panels.

6. The cockpit window of the aircraft having the electromagnetic shield according to claim 1, wherein the electromagnetic shield film is provided on an inner perimeter side from a portion fastened by the inner retainer and the outer retainer and the connecting film is inserted in the portion.

7. An aircraft comprising the cockpit window having the electromagnetic shield according to any one of claims 1 to 6.

8. A cockpit window of an aircraft having an electromagnetic shield comprising:

a plurality of laminated transparent widow panels;

an inner-side inner retainer and an outer-side outer retainer provided to an outer perimeter part of the window panels, the retainers interposing the window panels and made of a conductive material;

a coupling member coupling the inner retainer and the outer retainer to each other;

a weather seal provided between the outer retainer and the window panels;

an electromagnetic shield film provided between two of the window panels that are opposed to each other and made of a conductive material; and

a connecting film made of a conductive material and electrically connecting an outer perimeter part of the electromagnetic shield film and the outer retainer, wherein the connecting film has one end interposed between two of the window panels that are opposed to each other to be electrically connected to the electromagnetic shield film and has another end connected to the outer retainer outside the window panels, and an intermediate part between the one end and the other end is along an outer perimeter surface of the window panels and is provided so as to fill a space between the outer perimeter part of the electromagnetic shield film and the outer retainer.

9. The cockpit window of the aircraft having the electromagnetic shield according to claim 8, wherein the connecting film and the electromagnetic shield film are connected via a band-shaped connecting member provided so as to surround the outer perimeter part of the electromagnetic shield film, the connecting member being made of a conductive material.
