Sensor Wing Installed on F-22 Flying Test Bed
Boeing has installed a unique sensor wing, designed to help test F-22 avionics, on its 757 Flying Test Bed.
The sensor wing gives Boeing the capability to test and integrate U. S. Air Force F-22 avionics in parallel with airframe testing currently under way at Edwards Air Force Base, Calif., and long before avionics testing occurs onboard an F-22 aircraft.
Installed on the crown of the modified 757 jet, the sensor wing was designed and built to simulate the same wing sweep and orientation as an F-22 wing. Additionally, communication, navigation and identification (CNI) sensors will be mounted directly on the wing to simulate sensor positioning on the F-22's wings.
Bob Barnes, Boeing F-22 program manager and vice president, said the sensor wing, together with the test bed, will play a crucial role in flight-testing the highly advanced integrated avionics system developed for the F-22 fighter.
"Our test bed will help reduce avionics development costs by enabling extensive in-flight testing, evaluation and troubleshooting before much of the avionics are ever installed on the F-22," Barnes said.
The test avionics will be operated from a simulated F-22 cockpit, which has been installed in the test bed cabin. The cockpit has primary and secondary F-22 displays, as well as the throttle and stick. Software engineers and technicians will be onboard to evaluate the avionics during testing. Avionics flight tests will begin in early 1999.

The RWR is a passive radar detector with more than 30 antennas blended into the wings and fuselage for all-round coverage. Tom Burbage, former F-22 program head at Lockheed Martin, described it as "the most technically complex piece of equipment on the aircraft." The range of the RWR (250+ nmi) exceeds the radar's, and can cue radar emissions to be confined to a narrow beam (down to 2° by 2° in azimuth and elevation) to increase stealth. Depending on the detected threat, the defensive systems can prompt the pilot to release countermeasures such as flares or chaff. According to Bill Sweetman, experts had said the ALR-94 can be used as a passive detection system capable of searching targets and providing enough information for a radar lock on.

(Hence why ALR-94’s antenna are the entire leading edge of the F-22’s wings and other areas) ALR-94 is what makes the F-22 deadly…not the APG-77.

Impressive CG, however I'm still sure that the main bay can only hold two of these larger PL-15 each.
Just a quick question for a modeller, who contacted me: which of the so far delivered operational J-20s has the splinter camouflage ??
From the few images available I would say 78273 & 78174 ?
For 78273 I'm almost sure with the rear fuselage...

And for 78274 also on the tails...View attachment 374613

It seems that the third LRIP J-20 has a new splinter patterned painting

who invent this nickname? it's better than "fat lightening", so cute!1500 F-35 flying pigs

Inventing nicknames is just about the most you can do for this forum.The name "Lighting II" is not used very frequently. It's simply a dumb name. "fat lightening" may sounds good in Chinese, but will be lost to English audience.
I invented nickname "Flying Pig" for F-35. This Flying Pig will get roasted, since it Can't Climb, Can't Turn, Can't Fight and Can't Run.
