I have long been wondering what is the official name of this little air intake tube located in front of the fan blades and its intended functions. I did search it on google but it was in vain. I guess that it may be a pitot tube installed inside a jet engine for gauging the airspeed of the engine intake air.

    $\begingroup$ It is not a pitot tube because it is open on both ends, and pitot tubes are only open on one end(with the exception of a water drain hole which is several times smaller than the main opening). It is more of a specialized static-pressure port. $\endgroup$ – Max Power Mar 9 at 22:28

That's the EPR inlet pressure sensor (there's another one located aft of the engine in the exhaust).

EPR = Engine Pressure Ratio, one way to measure thrust.

One will be the P2 (pressure) sensor, the other will be T2 (temperature)

    $\begingroup$ This could be improved by explaining the purpose of these sensors. $\endgroup$ – fooot Apr 10 at 15:29
