I see many Sukhoi planes have a similar feature. I circled it in red on the following picture. Anyone know what it is?
Please help me identify this aircraft part on Su-47

Why would a Sukhoi have 3 or more pilot tubes? Shouldn't one be enough to measure air speed? For example, the attached photo shows a minimum of 3 on a single plane.
why not? the tubes could be measuring systems temperature
its not necessarily about airspeed

Many if not all FBW equipped aircraft use multiple pressure/static measurement tubes to provide each of the flight control computers with an independent source. It's about safety and redundancy.
The standard Pitot tube for Su-47 is mounted in front of the fuselage; see: http://airvoila.com/wp-content/uploads/2008/10/sukhoi-su-47-berkut-aguila-dorada-esquema.jpg
In case of tail number 01 above (prototype) and 06 (flight test), those are probes used for measurements that are specific for V/STOL tests.
