Technical Field

The invention belongs to the field of airplane emergency oil drain system equipment, and relates to emergency oil drains with lightning protection characteristics.

Background

Meanwhile, in the flight process of the airplane, the airplane may be struck by lightning, the emergency oil outlet used by the -like airplane is an oil drain pipeline tail end and is made of metal materials and directly or indirectly lapped on an airplane structure, the indirect lapping is usually carried out by using a lapping wire, the method cannot avoid generating large inductance and cannot prevent lightning from striking an arc at a fastening piece and igniting combustible steam of an oil tank, and the direct lapping is usually carried out by surface lapping, needs enough bare metal surfaces, does not have a corrosion-resistant coating and has the defect of poor corrosion resistance.

Disclosure of Invention

The invention aims to provide emergency oil discharge ports with lightning protection characteristics, so that when an airplane is struck by lightning in the flying process, the lightning cannot enter an oil tank through the emergency oil discharge ports, sparks or electric arcs capable of guiding fuel vapor in the oil tank are generated, and the problem of poor corrosion resistance is solved.

The application provides emergent oil drains, emergent oil drain includes emergent oil drain main part 1, locking structure, the clamp 4, second clamp 5, wherein:

the material of emergent oil drain main part 1 is insulating material, emergent oil drain main part 1 is connected through second clamp 5 with emergent oil drain pipe end, emergent oil drain main part 1 is through clamp 4 and wing wallboard electricity overlap joint, emergent oil drain main part 1 is connected with the wing wallboard through locking structure.

Optionally, the emergency oil drain body 1 is contoured to the aircraft wing trailing edge profile .

Optionally, the locking structure comprises a self-locking pallet nut 2 and a bolt 3.

Optionally, an overlap line is arranged inside the th hoop 4, and the emergency oil drain main body 1 is electrically overlapped with the wing panel through the overlap line inside the th hoop 4.

Optionally, the emergency oil drain port main body 1 is made of a rubber material.

Optionally, the pipeline of the emergency oil drain port main body 1 is arranged according to the airflow direction when the aircraft flies horizontally.

Optionally, the drift diameter of the emergency oil drain body 1 is equal to the drift diameter of the emergency oil drain pipe.

Optionally, the second clip 5 comprises a quick release clip.

The emergency oil discharge port made of the insulating material has the advantages that lightning cannot enter the oil tank through the emergency oil discharge port, sparks or electric arcs which can sufficiently lead fuel steam in the oil tank are generated, flight safety is guaranteed, meanwhile, a bare metal surface is not needed, and corrosion is avoided.
