ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to hinges generally and more particularly to an aircraft hinge and cover.
BACKGROUND OF THE INVENTION
Modern aircraft have avionics bay access doors or equipment access doors with piano type hinges. These access doors allow maintenance personnel to repair equipment and avionics stored behind these doors. Unfortunately, piano type hinges stick out of the moldline of the aircraft slightly and create drag. In addition, the piano hinges allow vapors, dirt and liquids to seep into the compartments. These contaminants can reduce the lifetime of the avionics and equipment.
Thus there exists a need for an aircraft hinge that does not create drag and does not allow contaminants into the equipment and avionics bays.
SUMMARY OF THE INVENTION
A hinge on an aircraft that overcomes these and other problems has a first plurality of rigid tangs attached to the aircraft. A second plurality of rigid tangs are attached to a door and a flexible cover has a cover tang. A hinge pin runs inside the first plurality of rigid tangs, the second plurality of rigid tangs and the cover tang.
