carbonyl iron ferrite 羰基鐵氧體，隱形戰**身的塗料(RAM)中含有這種物質
F-117A Nighthawk 夜鷹
洛克希德F-117A Nighthawk 夜鷹是一種單座,楔形,V-型尾翼,低可見度,具有對雷達偵測隱秘性的夜間攻擊戰鬥機
The basic principle behind RAM coating is this: the coating contains carbonyl iron ferrite (special paint using this material is known as ‘iron ball’ paint).
RAM 塗料的基本原理是:塗料中含有羰基鐵氧體 (carbonyl iron ferrite )
When a radar wave encounters this coating, it creates a magnetic field within the metallic elements of the coating. The field has alternating polarity and dissipates the energy of a radar signal.
Constructed primarily of aluminum, the F-117A's fuselage comprises flat panels known as facets mounted on the aircraft's subframe, their purpose being to reflect radar energy away from the transmitter itself, thus denying the operators a visible 'return'.
All surfaces are coated with various radar absorbent materials. All doors and panels have serrated edges to further minimize radar reflection. Grid covers on the intakes and the use of narrow-slot 'platypus' exhausts surrounded by heat-absorbing tiles further reduce the chances of IR detection.
