Chin
Chin turns up in 2 fields: aviation, textiles. Here is what it means to the people in each one.
Chin in aviation
The lower forward section of an aircraft fuselage, situated directly beneath the nose.
The chin is the underside of an aircraft's forward fuselage, located just below the radome or nose cone. This area is frequently used to house specialized equipment that requires an unobstructed forward or downward field of view, such as electro-optical targeting systems, weather radar, or chin turrets on military helicopters. On some piston aircraft, the chin houses the engine air intake.
"Maintenance found a bird strike dent right on the chin fairing during the walkaround."
Chiné in textiles
A mottled or speckled fabric appearance created by warp printing or twisting different colored threads.
Chiné describes a fabric with a blurred, speckled, or mottled pattern. This effect is traditionally achieved by printing the warp yarns before weaving, which slightly misaligns the colors as the weft is inserted. It can also refer to yarns made by twisting tightly contrasting filaments together to create a heathered look.
"The client wants a chiné silk for the lining to give it that soft, watercolor effect."
