Protective structure

1 . A protective structure ( 1 ) comprising:

a body ( 2 ) which is an air and/or space vehicle;

at least one protective layer ( 3 ) made of vanadium oxide (VO2) located on the body ( 2 ) and has conductive or insulating properties at a temperature predetermined by a user;

at least one magnetic layer ( 4 ) coated on the protective layer ( 3 ) with an impedance value predetermined by the user, wherein when warfare waves (F) directed to the body ( 2 ) for an attack is almost equal to the impedance value predetermined by the user, the magnetic layer ( 4 ) substantially absorbs the warfare waves (F) and is heated by high resonance frequency, thus increasing a temperature of the protective layer ( 3 ) and rendering it a conductive structure, so that the warfare waves (F) are reflected back from the protective layer ( 3 ); and

at least one radar absorbing layer ( 5 ) located between the body ( 2 ) and the protective layer ( 3 ), wherein when radar waves (G) are directed at the air and/or space vehicle with an impedance value lower than the impedance value of the magnetic layer ( 4 ) predetermined by the user, are at least partially absorbed on the magnetic layer ( 4 ) and create a low resonance frequency, the radar absorbing layer ( 5 ) allows the protective layer ( 3 ) to act as an insulator by remaining under the temperature predetermined by the user, and allows the radar waves (G) passing through the protective layer ( 3 ) to be substantially absorbed.

2 . A protective structure ( 1 ) according to claim 1 , wherein the magnetic layer ( 4 ) located on the protective layer ( 3 ) has a surface resistance value predetermined by the user that is higher than the surface resistance value of the protective layer ( 3 ), thus obtaining a capacity increase in absorbing electromagnetic waves.

3 . A protective structure ( 1 ) according to claim 1 , wherein the magnetic layer ( 4 ) has a hexagonal ferrite structure, which heats up as a result of electromagnetic waves absorbed thereon and allows the protective layer ( 3 ) to be triggered directly such that the protective layer ( 3 ) is transformed into a conductive phase.

4 . A protective structure ( 1 ) according claim 1 , wherein the protective layer ( 3 ) located on a surface of the body ( 2 ) substantially surrounds electronic equipment inside the air vehicle.

5 . A protective structure ( 1 ) according claim 1 , wherein the magnetic layer ( 4 ) located on the protective layer ( 3 ) has a thickness predetermined by the user in order to determine the impedance value of the magnetic layer ( 4 ).

6 . A protective structure ( 1 ) according claim 1 , wherein the protective layer ( 3 ) is doped with silicone, thus reducing a transition temperature from a monoclinic phase to a rutile phase.

7 . A protective structure ( 1 ) according to claim 1 , wherein the radar absorbing layer ( 5 ) is coated on the body ( 2 ) using a spraying method.

8 . A protective structure ( 1 ) according to claim 1 , wherein the protective layer ( 3 ) is coated on the radar absorbing layer ( 5 ) using a spraying method.

9 . A protective structure ( 1 ) according claim 1 , wherein the magnetic layer ( 4 ) is coated on the protective layer ( 3 ) using a spraying method.

10 . A protective structure ( 1 ) according claim 1 , comprising at least one polymer layer ( 6 ) coated on the magnetic layer ( 4 ) using a spray coating method which allows the magnetic layer ( 4 ) to be protected against factors such as humidity and/or friction.

11 . A protective structure ( 1 ) according claim 1 , wherein the magnetic layer ( 4 ) is made of barium ferrite, manganese ferrite, cobalt ferrite, nickel ferrite, copper ferrite or zinc ferrite.

12 . A protective structure ( 1 ) according to claim 1 , wherein the radar absorbing layer ( 5 ) is made of indium tin oxide or zinc tin oxide.

13 . A protective structure ( 1 ) according claim 1 , wherein the body ( 2 ) to which warfare waves (F) with an intensity or wavelength predetermined by the user are directed.

14 . A protective structure ( 1 ) according claim 1 , wherein the body ( 2 ) to which radar waves (G) with an intensity and wavelength predetermined by the user are directed.
