I agree with this. The SR-71 had a cesium additive in its jet fuel to reduce the heat signature of the aircraft. We could be seeing the same situation. Note that Blackbird pilots never got sick since their life support systems were LOx and they flew with zero-G suits.
If this is the same case, the OBOGS should be scrapped on the Raptor. The flight suits should be changed to something very similar to the zero-G, and life support systems should be replaced with the tried and true LOx. Though it is more maintenance to refill these bottles, it is incredibly more efficient than the OBOGS. However, the aircraft’s range may be limited since only so much oxygen can be provided.
If you notice, these issues were arising since the crash near Edwards. The Raptor was already flying in 2005 and no life support problems were ever reported (covered up), rather avionics issues were exposed and corrected promptly.
With the announcement of Increment 3.3 in the future, F-22s will be upgraded to use the JHMCS for off-boresight AIM-9X capabilities. There are further upgrades planned on the Raptor and its electronics suite to further surpass every other aircraft in existence. I sincerely hope that if Lockheed and USAF work at converting Raptors to the old school LOx system, they consider changing the flight suits to something that will make efficient use of a zero-G setup comingled with the advanced avionics & weapon system upgrades.
If true it’s most likely low frequency vibration from the engine/accessories, not out gassing.
BTW.. What is a “ZERO-G Suit”???
I know of G- Suits, but nothing is going to create “Zero G” with a mere garment.
“Blackbird pilots never got sick since their life support systems were LOx and they flew with zero-G suits.” The high-altitude suits were partial pressure suits, thus requiring a rubber diaphragm around the wearer’s face. I believe they were on O2 long before they left those little vans. So no chance of breathing any aircraft exhaust. We had 6 Habu’s at KAB, when I was stationed on the Rock, 73-75.
