according to back issue of aviation week,US also seeking way either to get rid or find alternative to pitot tube.in the end they gave up.
according to the magazine F-117 stealthness was "compromise" by pitot tube.
Come on guys, aviation week????,, F-117, that was first gen L/O, but it worked very well, only ONE wobbling goblin lost in combat in a very tough G2A environment???? The J-20 IS IN FLIGHT TEST, quit worrying about the stupid pitot tube, they are gathering data to build an aircraft, they NEED all the data they can come up with, IT IS CHINA's maiden voyage on L/O, and they want to get it right, that Pitot ain't goin no--where, it is mining flight test data on every flight. It remains a PROTO-TYPE, not LRIP as is the J-15. If they are going to emulate another aircraft it is going to be the F-22, which is, and will remain the one and only STEALTH FIGHTER, although that technology is now 25 years old. The F-35, T-50, nor the J-20 are very unlikely to match, much less exceed the L/O characteristics of the Raptor, period, exclamation point! The Raptor remains a BLACK AIRCRAFT, the last of the real skunkworks babes, the one good thing about the sequester is that they will cut flying hours on chick, hopefully preserving those airframes for the day they will be called upon to defend America..brat
