Abstract:
An extractor system for extracting smoke and other unwanted gases from an interior of an aircraft, wherein said extractor system comprises:(a) an external air receiver mounted outside the fuselage of said aircraft, said external air receiver comprising:a housing case,a funnel-shaped chamber situated within said housing case with a ram air entrance and a ram air outlet, said funnel-shaped chamber extending longitudinally in said housing case, anda hollow siphoning tubing being affixed at the center of said chamber along a longitudinal axis of said chamber, wherein said hollow siphoning tubing has a first end centered concentrically with said ram air outlet of said chamber, and has a second end connected to said air flow conduit tubing; said hollow siphoning tubing being angled so that said second end exits from said chamber and said housing case in a direction perpendicular to the longitudinal axis of said chamber,wherein when said aircraft is in motion, air flow outside said aircraft enters said ram air entrance and exits through said ram air outlet, and induces said suction force at said first end of said hollow siphoning tubing, said suction force being further induced to said vent receptacle through connection of said air flow conduit tubing,(b) a vent receptacle installed in the interior of said aircraft, and(c) an air flow conduit tubing interconnecting said external air receiver and said vent receptacle,wherein air flow outside of said aircraft entering said external air receiver when said aircraft is in motion induces a suction force sufficient to extract smoke and other unwanted gases from the interior of said aircraft to the outside of said aircraft, through said vent receptacle and said air flow conduit tubing.
