Is the Air Force's F-22 fighter jet making pilots sick?

[@ralfidude]

Because they just found out recently that its not the oxygen thats screwed up, its the G suit that inflates when the aircraft is NOT pulling G's, therefor restricting the pilot's oxygen indirectly.

[@thomasodetinape4180]

Nonsense

[@cas343]

There's 4 kinds of hypoxia: - Hypoxic: caused by reduced O2 in the blood. - Stagnant: caused by hard acceleration on the body. - Histotoxic: some contaminant such as CO or alcohol taking the place of O2 in hemoglobin. - Hypemic Hypoxia: CO2 levels drop and you can't absorb any more oxygen (hyperventilation). The F-22 pilots had 3 of these. I've done hypobaric training and the onset of hypoxia is quite insidious. You won't notice until its almost too late.

Finally thank you. 🫡 Weird it’s coming by all of us again. I was just talking to an older gentleman who was a pilot and had commented on this 12 years ago. (He is well)

[@MrPepelongstockings]

No. The air force officially identified the issue shortly after this came out. It was the upper G-suit that went over the shoulders and upper rib cage. It overinflated at high speeds (as designed, to increase external pressure on the body to keep blood in the brain) and restricted already weakened breathing too much. In typical military style, they stopped making reports on F-22 pilot's health public after this, but they were sure to note an overall (across all airplanes) reduction in reports of pilot hypoxia of 62% after the changes were made. In other words - this official issue could not be the actual issue and we don't know what the current rate of hypoxia in F-22 pilots is anymore, but fewer cargo pilots are going hypoxic. Problem solved. "The cause of hypoxia-like symptoms experienced by F-22 Raptor pilots was identified in 2012 after extensive investigation. The U.S. Air Force determined that the upper pressure garment of the G-suit assembly was inflating improperly, restricting pilots' breathing. Additionally, issues with hoses, valves, and cockpit connections contributed to oxygen supply problems. To resolve these issues, the Air Force implemented modifications, including a redesigned valve for the upper pressure garment and the addition of an automatic backup oxygen system (ABOS). These changes allowed altitude and distance restrictions on the F-22 fleet to be lifted in April 2013. Source: "F-22 oxygen issue resolved?" Airforce-Technology.

It seems like a dumb idea to run breathing air through the damn engine first.

[@marktorch9079]

I heard in 2022 They did identify the problem causing hypoxia and disorientation. The life support system was flawed. By taking off a specific filter it helped with some of the problems pilots had flying the F-22, Putting yourself in high G-Forces does have it's negative effect, like not being able to deliver oxygen to the bloodstream but is that just with the F-22 or do pilots flying other air-frames have similar issues. I would imagine the F-16 being the beast that it is would also cause Acceleration atelectasis giving the right circumstance

[@H2oRiz]

If the problem is fixed by taking oxygen up. Then the entire oxygen generating system has to be re-engineered and replaced, at Lockheed's expense

[@PchanStitch]

Given it's been over a year and they still don't have a clue what's causing it, I doubt that.

[@MetalMilitia6g7x]

I don't consider myself an aerospace engineer by any means but looking over the design makes me question if the unit is able to produce enough oxygen at high altitudes and during high speed maneuvers. Does the unit take into account the variables presented by atmospheric changes as well as change in engine speed?

[@Verdigo76]

Well part of the engine's air bleed system supplies pilots with oxygen to breathe. Commercial jets do the same thing. Im wondering if the radar absorbant material has anything to do with it. Its well known that the stuff flakes off and has to be reapplied often. I am thinking maybe its gettting into the air intake and contaminating their air supply. That or the air supply mechinism itself just sucks.

[@pntballer4life01]

Why don't they just install onboard oxygen tanks until they get it figured out? Also why go through the engine then to the pilots? It doesn't seem like that's a good idea in the first place. Who knows what they're breathing in then. Why not go to the pilot then the engine, or just have separate lines to the engine and the pilot?

[@birdseye2239]

Chat-GPT says the problem was: "Investigations identified that a combination of factors contributed to the problem, including a faulty valve in the pilots' high-pressure vests, which restricted breathing during high-G maneuvers, and fluctuations in the onboard oxygen generation system (OBOGS) that delivered excessive oxygen concentrations at high G-forces"

[@usaffuturecadet8062]

The F-22 has in flight sensors that that traack your heart rate, and blood preasure. If you lose consciousness during flight the plane will basically fly itself. Hence not so much of a danger to the community.

[@ffrgtm]

The Air Force specifically stated that the g-suit vests are not the root cause of the problem, but they believe they are contributing. All military equipment, especially a fighter jet, is engineered with a certain level of redundancy. A safety factor against failure modes. For a problem like this to occur, several things have to go wrong at once. That's what's happening... that's why this is so hard to solve.

[@tophat2002]

[@transformersboy6472]

[@darthregulus]

There is a bad design of oxygen rebreather systems, it must be a flaw so deep that fixing it would require a redesign. This is a tragic development.

[@JBC814]

If this is the same system used on the F-18, then your guess is probably right. The symptoms they describe are consistent with toxic contamination (dizziness, etc.), so the new carbon filters may do the trick. However, if it is not the same system as used on the F-18, et al, then the system may be inadequate for use on fighters, as MetalMilitia6g7x has stated below.

[@vojspetar3796]

Here's the problem. OBOGS is an outdated system that should have never been put into the aircraft. They should have used a LOX system like that of the F/A-18, which works great. OBOGS is fine in patrol aircraft, but for a fighter you need a LOX system. After a decade of dealing with these systems, I can tell you that who ever put the OBOGS system in the F-22 was a complete moron, and should be fired for incompetence.

Obviously there are contaminates in the oxygen. It can't be anything else. Need monitors to measure all variables in the system. I would think that the engines should not have anything to do with the pilot's air supply.

[@willboe33]

Has anyone checked the OBOGS system. According to this story the air feed for it 'runs through the engine', and then to the O2 generator. It seems to me that it is possible to find intense heat, and serious toxins inside a jet engine as a result of burning a shitload of Jet A fuel. Or maybe it is Jet M by now. Also, as pointed out by SacredSocietyAP below, a LOX system is much better than OBOGS. It must be cheaper to retrofit an f-22, or two, with LOX than to kill pilots & planes.

i'm no aerospace engineer, but is it possible the capabilities of these advanced aircraft exceed the physiological capabilities of the human body? Is it perhaps not an engineering problem we need to seek, but a physiological limitation that needs to be addressed? What were the pulse oximeter readings throughout a sortie? Did O2 sat rates decline with a particular maneuver or at a particular speed? Is CO entering the system and disrupting hemaglobin's ability to transport O2?

[@wildmanturner]

It’s called Atelectasis. Maybe some congestive fluid build up in the lungs as well.

[@lMrWongl]

It is probably the air coming from the engines that still may have enough resadue to give a pilot hypoxia

[@Exoticgirl1]

I am rather thinking of problems with the pressure inside the cabin of plane. One does not get the bends from a lack of oxygen (Kaptain Wilson has been treated in a decompression chamber!), but from a dramatic sudden pressurechange. What if the problem is in the hull of the plane, rather than in the oxygen supply!! I mean, they go from groundlevel to extreme hights in no time, right. If it were the oxygen supply they could easily test that by equipting the men with airtanks.

If the oxygenation system is siphoning air from outside the plane, wouldn't that include the thermal fumes, vapors and exhaust from the after burners? As well as atmospheric gases and pollutants in the surrounding atmosphere? I get that it's filtering the oxygen but these factors have to be taken into consideration. The engineers must have missed these factors.
