Abstract:
PURPOSE: A composite-material flat panel for reducing a radar cross section using shaped reflector is provided to prevent the influence to the location of a vessel and mounting equipment. CONSTITUTION: A composite-material flat panel for reducing a radar cross section using shaped reflector comprises a center reflection plate(100), a FRP(Fiberglass Reinforced Plastic) flat board(200) and a filler(300). The center reflection plate is provided to be formed by arranging triangular flat plates(110) side to side. The center reflection plate prevents the single reflection and the strong multiple reflection by controlling the direction of reflected wave of the radar signal. The FRP flat board prevents the flotation of the rise of tide circle by the sharp center reflector as coverage. The filler protects the FRP flat board by absorbing external shock.

PURPOSE: A composite-material flat panel for reducing radar reflection signals using a shaped reflector is provided to have RCS reduction effects by releasing single reflection and multiple reflections generated by warships and mount equipment. CONSTITUTION: A composite-material flat panel for reducing radar reflection signals using a shaped reflector comprises a central reflective plate(100), an FRP flat plate(200), and filler(300). The central reflective plate is formed to alternately arrange an inclined element flat plate(110) and a vertical element flat plate(120). The FRP flat plate covers the both outer surfaces of the central reflective plate. The FRP flat plate reinforces the rigidity of the whole panel.

본 발명은 재난 발생에 따른 외부의 물리적 위험으로부터 내부 공간에 탑승한 탑승자를 보호하기 위한 외형부를 포함하는 안전 보호구에 관한 것으로서, 상기 외형부는 상기 물리적 위험을 차단 및 흡수할 수 있는 탄성 재질로 마련되되, 평상시에는 접어져서 보관될 수 있으며, 재난 발생 시에는 공기 탱크로부터의 공기 유입으로 인해 부피가 팽창됨으로써 상기 내부 공간이 마련된다.
Abstract:
PURPOSE: A composite-material flat panel for reducing a radar reflection signals using a shaped reflector is provided to release single and multiple reflections generated by a warship and mount equipment without shaping the structure of a warship hull and the mount equipment or using a radar absorber. CONSTITUTION: A composite-material flat panel for reducing a radar reflection signals using a shaped reflector comprises a central reflective plate(100), a FRP flat plate(200), and filler(300). The central reflective plate is shaped to arrange an inclined element flat plate(110) in a zigzag shape. The FRP flat plate covers the both outer surface of the central reflective plate. The filler is filled between the central reflective plate and the FRP flat plate and contacts the central reflective plate and the FRP flat plate. The filler absorbs external physical impact and protects the FRP flat plate.
