PROBLEM TO BE SOLVED: To provide an optical window structure with which a required field of vision is secured by joining a plurality of optical windows, and which is lightweight and reduces a shield degree of the field of vision at joint parts of the optical windows, even when elastic deformation arises in an outer shell structure due to severe inner and outer pressure differences, temperature, and aerodynamic load in an environment installed in an aircraft or the like.SOLUTION: The optical window structure is constituted from a plurality of optical windows 1a and 1b and an outer shell structure 2 for holding the optical windows. The optical windows are fixed to a thin plate 3 at end parts of the optical windows, and the thin plate is fixed onto the outer shell structure.SELECTED DRAWING: Figure 3
【課題】複数枚の光学窓を継ぎ合わせにより所要の視野を確保する構造の光学窓構造において、航空機等に搭載する環境で、厳しい内外圧差、温度、空力荷重によって外殻構造に弾性変形が生じる場合であっても、軽量で、光学窓の継ぎ合わせ部に生じる視野の遮蔽の度合を小さくできる光学窓構造を提供する。【解決手段】複数の光学窓1a,1bと、前記光学窓を保持する外殻構造2からなる光学窓構造であって、前記光学窓は、前記光学窓の端部において薄板3と固定され、前記薄板は、前記外殻構造に固定される。【選択図】図3
