AUTOMATICALLY OPERATING DEVICE FOR SEALING A FUSELAGE RECESS OF AIRCRAFTS

Sealing device for an aircraft fuselage. For adjustable wing aircraft whose wings retract into the fuselage under certain conditions of flight there is provided resilient sealing means at the upper and lower sides of the wing receiving recess for closing the recess and providing a smooth fuselage contour in all positions of the wing. The sealing means comprise a resilient tube arranged at each of the upper and lower edges of the recess and so proportioned to the size of the recess that they are pressed together under some appreciable pressure even when the wing is extended. In one form of the invention said sealing tube is comprised of spirally wound spring wire which if desired may be of multilayer construction, said multilayers being, if desired, wound in opposite directions. In other embodiments, the resilient tube may be enveloped by an elastic material for conforming the closure means to the contour of the aircraft.
