摘要:
A drip pan apparatus for use in a helicopter includes a drip pan and a frame having a plurality of frame sides and a plurality of frame corners that define an inwardly-facing peripheral surface. A first frame angle is formed between a first inwardly-facing surface and a second inwardly-facing surface. The first frame angle is an acute angle. The drip pan has an outwardly-facing peripheral surface. The outwardly-facing peripheral surface defines a plurality of sides, including a first side and a second side, to cooperate with the inwardly-facing peripheral surface of the frame. A first angle is formed between the first side and the second side. The first angle is an acute angle. A method of installing a drip pan includes modifying at least a portion of a skirt on the helicopter and then securing the frame to one or both of the modified skirt and the helicopter structure.

A drip pan apparatus for a “M” model BLACK HAWK® helicopter and the like includes an expanded corner structure for accommodating an access port also positioned further outwardly in the corner than in prior drip pan apparatuses, facilitating filter viewing while retaining peripheral o-ring seal. An expanded corner of the airframe skirt is accommodated by the expanded corresponding corner of a frame, which also defines a small radius internal curve. The removable pan has a small radius curve cooperating with the small radius curve of the frame and is sealed thereto by the peripheral o-ring seal sealing the entire pan to the frame. Physical access to the filter is enhanced.
摘要:
A drip pan apparatus for a helicopter includes a frame and a drip pan. The frame is secured to a skirt on the airframe of the helicopter. The apparatus includes a drip pan for cooperation with a frame to cover an access opening to a transmission. The drip pan includes a substantially planar member of a fiber-reinforced composite and has a seal surface that is configured to cooperate with a seal surface of the frame. A seal member may be disposed between the substantially planar member and the frame to form a fluid-tight seal. The fiber-reinforced composite may be a carbon fiber-reinforced composite. A method of making the drip pan apparatus includes placing a plurality of sheets of an uncured fiber-reinforced composite material on one another to form an uncured stack. The uncured stack is then cured. A frame and a drip pan may be cut from the cured stack.
