Why are A-10 attack aircraft suspended in the USA?

43
Profile Edition Aviation Week reports on the increasing incidence of deterioration of health of pilots of attack aircraft A-10 Thunderbolt II of the USAF. Recall that we are talking about attack aircraft, the production of which in the United States was carried out in the period from 1975 to 1984 years. During this time, more than 700 of such twin-engined aircraft were produced.


Why are A-10 attack aircraft suspended in the USA?


In the American media reports appeared that pilots often began to complain of hypoxia episodes, manifested during flight operations. In particular, several incidents were reported in the Davis Mountain Air Base area in Arizona. After that, an assumption appeared that the liquid oxygen supply system LOX (oxygen stations OBOGS) operated on attack aircraft with malfunctions.

The pressure in the cockpit of the attack aircraft during flights dropped below the permissible parameters, and it was not possible to identify the specific causes of such problems at the moment. This fact was the reason for the decision to suspend the implementation of flights on the A-10 Thunderbolt II. At the moment it is known that about thirty American attack aircraft of the mentioned airbase remain on the ground before the completion of the work of the commission of specialists.

For reference: A-10 Thunderbolt II weighs about 9,2 T (empty), while the maximum take-off weight is over 21 T. The maximum allowable speed of the aircraft is about 830 km / h. Practical range with maximum combat load is 740 km. The length of the takeoff of the aircraft - 1,1 km, the length of the run - 623 m.

    Kanabis is the main enemy. And then there Putin is either thrashing with climatic weapons or hypoxic.

      You just need to attract the Russians to this problem - half a year and the question would be answered. laughing hi
      They have problems with providing life support systems not only in aviation, but also in space.

          laughing Then the guys in Syria were making fun of themselves when they drove a SU-30SM near the 76th ramp, so the whole Internet exploded, especially the English one. And what was it? Small air hooliganism. Well, the man forgot the matches, he wanted to ask the peasants, but the window was jammed from him .. And it began: "Are they working without insurance ???" , "Russians are just crazy, are we going to fight?" wassat . Patsaki, you can’t even imagine what kind of crazies we are when they bring you, your disk is empty, and the RAM is reset faster than the cache, do not remember anything.

          So this is not about the Su-25, which was not originally intended for this. It is a matter of the fact that not only the Warthog had these problems, but the F-35s and the shuttles could not be in space for a long time (since life support systems were undeveloped). hi

            And on the F-35, and on the F-18, now on the attack aircraft - the same problem.

              Warrior, good evening! A couple of years ago I read the opinion of the Russian specialist on this issue. He said that it was all about automation and differential pressure at different heights. What is the need to adjust this automation from flight altitude. If I understood him correctly. hi

    Hypoxia is a process caused by a too low total oxygen content both in individual organs and throughout the body.

    Oxygen starvation occurs when there is not enough oxygen in the inhaled air. Because of this, over time, a lack of oxygen begins to appear in tissues and blood, and then hypoxemia develops, which is a consequence of a violation of biochemical processes during tissue respiration.


    Something bad is poked into the oxygen breathing apparatus of this plane ... only a specialist can figure it out what

      Not only this, on the "penguin" similar problems were identified. The whole world has been flying with oxygen devices on airplanes for almost a hundred years, and only the problem has been identified for Americans. laughing Along the way, they generally lack oxygen in the brain. They complain of hypoxia. But they didn’t try to open the oxygen tap? laughing

    Strange, for decades flew without complaints from the pilots and suddenly on you. Is there any kind of sabotage or do the pilots have no desire to go to war?

        Neither A-10, nor F-22, nor F-35 suit them. And this is good!

        The U.S. Air Force will spend $ 7 million on chemical oxygen analyzers for fifth-generation F-22 multirole fighter jets. So experts plan to understand what disrupts the operation of oxygen generation systems OBOGS (OnBoard Oxygen Generating System, OBOGS) and leads to a lack of oxygen to the crew. It is also planned, to study the blood test of pilots during the flight, to understand the causes of malfunctions.

        It has now been established that the F-22 Raptor aircraft pilots feel unwell, including the increased content of nitrogen and other impurities in the supplied air mixture, the interruptions in the supply of which are unstable and cannot be predicted. Earlier it was reported that in May 2011 it was known about fourteen cases of interruption in the supply of oxygen on the 5th generation F-22 fighters, due to which the state of the pilots worsened as a result of hypoxia, and in several cases the pilots lost consciousness.

        In addition to F-22, OBOGS is installed on F-16, F-15E, A-10, F-35, F-18 and other US aircraft. In this case, the oxygen supply problem arose only on the F-22 of the US Air Force and on the F-18. Between 2002 and 2009, the United States Navy reported 64 cases of interruptions in air supply to F-18 crews. Twice this ended in the death of pilots. However, on the F-18, the cause of the malfunction was discovered - carbon monoxide entered the oxygen system - and eliminated. At the same time, about 77% of incidents occurred on single-seat Hornets. On the F-22 USA, such a malfunction was not noted.

        Earlier, during the investigation, Honeywell representatives said that the cases of suffocation of F-22 pilots are associated not only with the operation of OBOGS, but also with other life support systems on the fighter. For example, a breathing mask that does not fit well to the face. Another reason was called the asynchronous operation of the anti-overload suit of the pilot and the breathing system. The upper part of the pilot’s suit is also connected to OBOGS and when changing the flight altitude and pressure inside the cockpit provides compression of the chest so that the pilot can breathe normally with rapidly changing atmospheric pressure. Such a solution helps prevent chest expansion with a strong decrease in atmospheric pressure, which can cause circulatory disorders. According to one version, due to a malfunction in the “boost” control system, the suit could squeeze the pilot’s chest too much, blocking breathing. According to another version, hypoxia attacks could begin due to improper collaboration between OBOGS and the respiratory mixture supply system in the pilot's mask.

        And now the Warthog apparently got infected with all these sores ...

    Something is wrong with aviation! A similar thing happened with f15, and with f16 and with f22, and with f35! And everywhere there are problems with the air supply system! There is clearly a technical defect there, or the air supply system itself was initially incorrectly designed!

      Perhaps the air is not democratic enough.
      Suddenly there is no matter what the part is from Russia, a titanium bolt. Of course, air will immediately turn into totalitarian air, which citizens of the free world cannot breathe.

      In general, it’s really strange - they flew for many decades, and it’s normal. And then suddenly everything is bad.

      It also became interesting while the specialists were silent
      OnBoard Oxygen Generating System (OBOGS) introduced in the US military aviation since the 1990s to ensure longer flight duration. OBOGS is a device designed to provide the pilot with a breathing mixture during flight. To operate the system outboard air usedpumped by the engine into a special receiver, where the air is cleaned of nitrogen and other gases, and the remaining mixture, with a predominance of oxygen, is fed into the pilot's mask.

      Nitrogen purification is phenomenal. request
