- Russian Sukhoi 5G fighters boast cutting-edge life support systems defeating US F-22 Raptor?.

Moscow: The Russian Sukhoi T-50 5G fighter jet is equipped with cutting-edge computerized life support systems, including an oxygen station securing unlimited breathing gas supply and advanced pilot’s compensation system that anticipates gravity overload.
The research and development enterprise Zvezda has announced the final tests for its onboard oxygen generation system that will be installed on all Russian operating fighter jets, including those to be supplied abroad, Izvestia daily reports.
Unlike the 90 kilogram oxygen bottles system the new generator weights a mere 30 kilograms, a crucial weight and space economy in modern combat aircraft construction.
“Oxygen is produced from the atmosphere as the system takes it from the engine’s compressors and redirects it to pilot’s mask. Flight time no longer depends on oxygen supply,” Zvezda’s Chief Specialist Mikhail Dudnik told Izvestia.
It took five years to shape up the system, Dudnik said, but all four Sukhoi T-50 PAK-FA 5G fighter jets currently undergoing flight tests near Moscow were already manufactured with this system at a Sukhoi plant in Komsomolsk-na-Amure – a city located in Russia’s Far East. The 5G fighters made their way across the country without oxygen tanks onboard.
Soviet and Russian military aviation previously employed oxygen bottles – an old, but time-tested technology. But it also imposed certain restrictions on mission duration, because while refueling was an option for many long-range military jets, oxygen re-supply was not. So a pilot had to always keep a close eye not only on fuel, but also the oxygen capacity of his aircraft, as elevations 4 kilometers or higher require a breathable gas supply to avoid oxygen deficiency. An unexpected leakage of excess oxygen spending could lead the failure or termination of a vital mission.
Consequently, every Russian Air Force airfield is now equipped with oxygen producing stations, which must be manned by experienced personnel. Soon such stations will become a thing of the past.
9G antigravity suit
The advanced flying characteristics and super-maneuverability of Sukhoi T-50 fighter jet exposes pilot to extreme G-forces, actually reaching the human ceiling limit. A T-50 pilot cannot actually use the jet to its fullest potential without ultramodern technical assistance on a variety of fronts.
That is why Sukhoi T-50 fighter jet pilot requires a brand-new antigravity G-suit capable of compensating up to 9G for an unprecedented 30 seconds the plane is thrust into a bone-crashing missile evasion maneuver.
The unique G-suit, developed by the same Zvezda enterprise, allows the pilot to eject from the plane at the height of up to 23 kilometers.
The onboard computer anticipates overload and avoids the delay of the system response to pressure compensation. The gravity compensation system calculates everything, from the air pressure created in the rete of flexible pipes entwisting the G-suit and supporting the pilot’s body to the 6-7 atmosphere air pumped into pilot’s lungs to compensate the external chest pressure and prevent him from blacking out.
US F-22 Raptor grounded for months due to oxygen supplyThe Sukhoi T-50 PAK-FA’s future major rival in the air, the American 5G F-22 Raptor fighter jet is equipped with its own On-Board Oxygen Generation Systems (OBOGS) developed by Honeywell.
Many modern aircrafts, like the F-22, F-35, B-1B, B-2B, Eurofighter, Gripen, Nimrod and others are equipped with this system. But only the F-22 has been plagued by a persistent fault – a deficiency of oxygen in the cockpit which leads to hypoxia.
Hypoxia occurs when the brain is starved of oxygen, causing dizziness, disorientation, blackouts and finally loss of consciousness. When operating a fighter jet that flies at nearly twice the speed of sound, even a momentary lapse could lead to catastrophe.
At least 25 American pilots out of some 200 have reported dizziness, disorientation and other symptoms similar to those associated with hypoxia while flying the F-22 – the world’s most expensive fighter jet – since 2008.

US Air Force Top guns ‘refuse’ to fly $143 million F-22 fighter jet Raptor

The first F/A-22 Raptor destined for the First Fighter Wing performs a fly-by shortly before being delivered 12 May 2005 at Langley Air Force Base, Viginia. (Win McNamee/Getty Images/AFP)America: The F-22 is the world’s most sophisticated operational fighter plane, and one of the most expensive. But due to an unexplained and potentially deadly problem that causes oxygen to drain out of the cockpit, pilots are refusing to be assigned to it.Read here Sukhoi News t-50 PAK FA the F22 Raptor Rival Fighter Jet.
Air Force General Mike Hostage admitted that a number of F-22 pilots are refusing to fly the stealth fighter until it is completely safe or have asked to be moved to different planes altogether. He did not specify how many out of a total of some 200 F-22 pilots refused, but claimed it was a “small number”.
Usually, securing a seat on the most modern plane in the USAF is a hotly-contested competition reserved for the best pilots.
But the F-22 has been plagued by a persistent fault – a deficiency of oxygen in the cockpit, leading to hypoxia.
Hypoxia starts when the brain is starved of oxygen. It can cause dizziness, disorientation and blackouts and, potentially, loss of consciousness. But when operating a jet that flies at nearly twice the speed of sound, even a momentary lapse could prove disastrous.
The Air Force has documented a recent flight when the pilot became so disoriented he allowed the plane to descend so low it brushed the tops of trees before he managed to compose himself and gain height at the moment of contact.
The most alarming thing is that hypoxia has been reported for years, and not only have the engineers not found a solution, but they don’t even understand what is causing the problem – whether it’s a design flaw or the body’s response to flying conditions.
The Air Force grounded the jets for five months last year while it examined them. It allowed the planes back up in the air in September 2011. Since then, it admits there have been at least eight more incidents of in-flight hypoxia.
A highly-placed Air Force panel is currently holding weekly meetings to discuss progress.
General Mike Hostage has even promised to personally climb into the cockpit. “I’m going to check out and fly the airplane so I can understand exactly what it is they’re dealing with,” he said.
Stuck in the hangar
The oxygen problem is the latest debacle in the life of a plane that has come under a firestorm of criticism.
At $79 billion for less than 200 planes – the final F-22 rolled off the production line last year – the entire program has been dismissed as exorbitantly expensive.
Despite being introduced into the Air Force in 2005, the stealth jet has not seen any action. Designed for air-to-air combat against other latest-generation jets it’s had no place in the counter-insurgency and bombardment missions the US has conducted in the Middle East and Afghanistan.
Now, with the more versatile and modern F-35 scheduled for introduction in 2016, the F-22 risks becoming a niche failure that never saw its time come.
And that’s even if it gets cleared for take-off.Link:
