  • Patent number: 6138950
    Abstract: In accordance with the present invention, there is provided an aircraft engine air intake cover for use with an air intake which is characterized by an air velocity profile therewithin. The air intake cover is provided with an air induction plate which disposed across at least a portion of the air intake. The air intake cover is further provided with a multitude of air induction ducts. The induction ducts are disposed about and extend through the air induction plate. Each induction duct has a duct inlet, a duct outlet and a duct body interposed between the duct inlet and the duct outlet. The duct inlets each respectively define an effective inlet diameter. The duct bodies each respectively define a duct body length which is greater than the associated effective duct inlet diameter. The duct outlets each respectively define an effective outlet diameter greater than the effective inlet diameter for increasing the cohesiveness of the air velocity profile within the air intake.

  • Patent number: 6059230
    Abstract: A deformable aircraft door which is movable between open and closed positions and is adapted to substantially maintain contact with the door frame for reducing a perimeter gap between the door and the door frame. The aircraft door comprises an edge portion which is formed to engage the door frame, and an elastic portion which is attached to the edge portion. The elastic portion is selectively expandable and contractible for permitting movement of the edge portion relative to the door frame when the aircraft door is in the closed position so as to substantially maintain contact between the edge portion and the door frame despite changes in the geometry of the door frame.
