Crash Relic: Pitot Tube, Luftwaffe Bf 109
Here is a WWII-era aircraft Pitot Tube crash relic, as used in aircraft of the German Luftwaffe such as the Bf 109 Fighter, and recovered from a crash site in Poland.
Typically mounted on the wing of the aircraft, the pitot tube was employed by pitot-statically-driven instruments to perform their function, e.g., airspeed indicator, vertical velocity/rate of climb indicators, and altimeters by measuring the differential pressure across two orifices as air is driven across their surface with the hollow tube.
Measures ~11 inches long and ~3/4 inches diameter. A very interesting artifact indeed.
