Installation structure of seeker window and flying object with seeker window

Abstract

A seeker window includes a transparent plate and a frame structure coupled to a circumference of the transparent plate. An installation structure of the seeker window has a flexible window frame which includes a window frame body section; a flexible section coupled to the window frame body section and the seeker window; and a fastener configured to fix the window frame body section to an inner structure of a nose section of a flying object.

What is claimed is: 
     
         1 . An installation structure of a seeker window,
 wherein a flying object comprises a fuselage section and a nose section having an opening for said seeker window and coupled to said fuselage section,   wherein said seeker window protects a seeker section disposed in said flying object,   wherein said seeker window comprises:   a transparent plate configured to transmit a light of a predetermined wavelength range for said seeker section; and   a frame structure coupled to a circumference of said transparent plate, and   wherein said installation structure comprises a flexible window frame which comprises:   a window frame body section;   a flexible section coupled to said window frame body section and said seeker window and configured to flexibly deform in response to a deformation of said seeker window; and   a fastener configured to fix said window frame body section to an inner structure of said nose section.   
     
     
         2 . The installation structure of a seeker window according to  claim 1 , further comprising a gasket disposed in a groove that is formed in a surface of said window frame body section facing said inner structure of said nose section, and configured to seal an inside of said nose section from an outer ambience of said flying object. 
     
     
         3 . The installation structure of a seeker window according to  claim 1 , wherein said window frame body section is accommodated in an inside of said nose section. 
     
     
         4 . The installation structure of a seeker window according to  claim 1 , wherein a surface of said window frame body section which opposes to a surface facing said inner structure of said nose section is exposed to an outer ambience of said flying object. 
     
     
         5 . The installation structure of a seeker window according to  claim 1 , wherein said flexible section is formed to have a bottom portion extending from an end surface of said window frame body section to a middle point and a rising portion extending outwardly along the end surface of said window frame body section while being apart from the end surface, and
 wherein said frame structure is tightly coupled to a surface of said rising portion on said seeker window.   
     
     
         6 . The installation structure of a seeker window according to  claim 5 , further comprising:
 a gap seal member filled in a gap between the end surface of said window frame body section and said rising portion of said flexible section.   
     
     
         7 . The installation structure of a seeker window according to  claim 6 , wherein said gap seal member comprises a plurality of plates which are separated from each other. 
     
     
         8 . The installation structure of a seeker window according to  claim 7 , wherein said plurality of plates are coupled at a coupling point one after another to have an interval, and
 wherein the coupling point is deeper inwardly than an inner surface of said seeker window.   
     
     
         9 . A flying object comprising:
 a fuselage section; and   a nose section having an opening for a seeker window and coupled to said fuselage section,   wherein said seeker window protects a seeker section disposed in said flying object,   wherein said seeker window comprises:   a transparent plate configured to transmit a light of a predetermined wavelength range for said seeker section; and   a frame structure coupled to a circumference of said transparent plate, and wherein an installation structure of said seeker window comprises a flexible window frame which comprises:   a window frame body section;   a flexible section coupled to said window frame body section and said seeker window and configured to flexibly deform in response to a deformation of said seeker window; and   a fastener configured to fix said window frame body section to an inner structure of said nose section.   
     
     
         10 . The flying object according to  claim 9 , wherein said installation structure further comprises a gasket disposed in a groove that is formed in a surface of said window frame body section facing said inner structure of said nose section, and configured to seal an inside of said nose section from an outer ambience of said flying object. 
     
     
         11 . The flying object according to  claim 9 , wherein said window frame body section is accommodated in an inside of said nose section. 
     
     
         12 . The flying object according to  claim 9 , wherein a surface of said window frame body section which opposes to a surface facing said inner structure of said nose section is exposed to an outer ambience of said flying object. 
     
     
         13 . The flying object according to  claim 9 , wherein said flexible section is formed to have a bottom portion extending from an end surface of said window frame body section to a middle point and a rising portion extending outwardly along the end surface of said window frame body section while being apart from the end surface, and
 wherein said frame structure is tightly coupled to a surface of said rising portion on said seeker window.   
     
     
         14 . The flying object according to  claim 13 , wherein said installation structure further comprises:
 a gap seal member filled in a gap between the end surface of said window frame body section and said rising portion of said flexible section.   
     
     
         15 . The flying object according to  claim 14 , wherein said gap seal member comprises a plurality of plates which are separated from each other. 
     
     
         16 . The flying object according to  claim 15 , wherein said plurality of plates are coupled at a coupling point one after another to have an interval, and
 wherein the coupling point is deeper inwardly than an inner surface of said seeker window.
