The reason for the indefinite grounding of the American F22

It has nothing to do with politics or economics, and in fact, it has nothing to do with the military. The overt problem is the oxygen system, which can occur at high altitudes and cause serious flight safety hazards, nothing more, grounding is a routine safety measure. Of course, in fact, the U.S. Air Force is taking advantage of the grounding to fully upgrade the F22A's avionics system.

How can you get involved in politics and economics about an aircraft technical problem.

The most recent investigation was not OOGS at all, and no one has ever asserted that it was a fault of OOGS, just that the early investigations took into account the symptoms and mainly focused on OOGS. In fact, what is now being investigated is the possible poisoning of the pilot, possibly the inhalation of exhaust gases caused by the operation procedure. It is possible that the aircraft may need to be moved, and it is likely that simple improvements to the steps and procedures will be able to solve the problem completely.

The postponement of the integration of MADL is interpreted as "complete abandonment of the upgrade project of the F22 communication system", I don't know how this translates. Before the F-35 entered service, the F-22 had no need for MADR at all, and early integration would be nothing more than an increase in risk and overhead. The reason for the incompatibility of Link 16 is that it will completely deprive the F-22 of its low-probability interception communication capability, and it is completely possible to solve the problem at the moment by relying on the BACN.

You must know that the F-16 is not the partner of the F-22, and the F-15 is just a coincidence of life extension.

The oxygen supply system is out of order, and the pilot is prone to suffocation and dizziness at high altitudes. Which one dares to fly?

The official news seems to be that there is a problem with the pilot's oxygen ** system. The grapevine is that there are deficiencies in the design. Can be locked in advance by radar.

Accidents are frequent and expensive.

When flying at high altitudes, oxygen will be insufficient, which will cause the pilot to be uncomfortable in a hypoxic state! Cause an accident!

The oxygen supply system failed, and the pilot's life was threatened.

The oxygen supply system is unreliable and the pilot flies with a lack of oxygen.

After a Raptor crashed in November last year, the US Air Force ordered in January that such aircraft could only fly in airspace below about 7,600 meters. Beyond this altitude, pilots may become dizzy due to lack of oxygen and lose the ability to control the aircraft.

It's all honeywell's fault (fog)...

I don't think it's surprising to be excited, because these people also have to admit that the F-22 is the most powerful and advanced tactical aircraft available today. No one cares if the MiG-21 falls a few times, and there is no depreciating value, just as no one will emphasize that they are richer than beggars.

The YF-22 and YF-23 proposals were selected as ATF candidates at the end of '86, with the Air Force each giving two companies a fixed contract of less than $700 million to build 2 prototypes each. The prototype of the YF-120, which was actually able to fly and launch ** (AIM-9A AIM-22), was 90 years. If you think that the J-20 has the completion of the YF-22, then now China has completed the work that the United States has done in the past four years, I think you can understand what this means.

I have studied all the layouts of the United States, not to mention NASA and other institutions, and a large number of pre-research of the company

The grounding of the F-22 does deal a major blow to the US Air Force, but this does not mean that the technology of the F-22 is not advanced enough, on the contrary, the stealth fighter represented by the F-22 is the development direction of the future fighter. The F-22 fighter is the highest level of development of aviation technology today, and its degree of sophistication and sophistication is far beyond people's imagination. The grounding of the F-22 is a reminder to all countries that are developing stealth fighters, and the development of advanced fighters puts forward higher requirements for a country's aviation technology and the logistics support capabilities of its military.

As for the aerodynamic layout of the J-20, the J-20 adopts a canard wing and delta wing layout, with two full-motion vertical tails and two small-area pelvic fins. Along the sides of the fuselage are sloping twin vertical tails, the wings transition smoothly with the fuselage, the front fuselage surrounds sharp edges, and the frameless monolithic cockpit resembles that of the F-22. The F-22 adopts a normal aerodynamic layout, and the advanced aerodynamic shape and body structure make it have a large static width stability and sustainable supersonic flight capability, while when flying at subsonic speeds, the F-22 has a high degree of longitudinal static instability.

The J-20 adopts a canard layout that is good for maneuverability and not good for stealth. To a certain extent, this reflects the development strategy of the Chinese Air Force based on China's national conditions and following Chinese characteristics.

The purpose of the United States in creating the F22 in the first place was indeed to seize air supremacy. But then it was given too much ability to multitask, with beautiful ideas and cruel reality. As a result of giving F22 too many task capabilities, it is more difficult to integrate the whole system, and even if it is barely achieved, it will inevitably be short-circuited at any time.

By the way, the F22 is now the fighter with the highest probability of crashes in the US Air Force in active service.

The ignorance, arrogance and ignorance of the people of the country.

The one in Alaska, where a malfunctioning oxygen system does have the potential to cause a crash.

However, the specific reasons must be analyzed on a case-by-case basis.

As long as it's a product, there will be problems, but if it's just an isolated phenomenon, then it's perfectly fine, they're cheating Congress out of money.

If a notification is issued for this aircraft, for example: training altitude restrictions, combat is not affected, and it has not been solved yet, it may be a real problem.

Don't be naïve, which model of fighter has not been grounded? Isn't it just a big problem, it's normal to ground the flight for safety, it's a problem with the oxygen supply system, it's not a big problem, and if it's solved, it's a very simple thing.

It's too expensive, aircraft carriers are super expensive, plus 200 million planes, who can afford it.

The main thing is the cost. The top brass of the U.S. Air Force, U.S. Navy, and U.S. Marine Corps decided to jointly decide to equip a generic stealth fighter based on the high cost of fourth-generation aircraft. This fighter is the F35.

And the reason for the development of the F35 is because the F22 is too expensive. It had to be an economical, low-end model that matched it with high and low.

Congress doesn't give money, and it's really not necessary. The naval version was planned for a long time, and it was canceled at the beginning of the 21st century, because it was not necessary. In fact, the most important thing now is to build new ships, and the main ships of the US Navy are still built in the Reagan era, which are seriously aging and urgently need to be replaced.

There are too many F22 crashes, and they have all been grounded without restrictions.

Let me start by saying that this hypothetical probability is basically equal to 0

Leave it alone, there's no way to deal with it anyway. Persimmon picks up the soft pinch, who has the disease to find the hardest dry rack? How do you look at it, the most prominent piece of equipment in the four armed forces is the F-22.

Although "avoiding the edge" is much easier said than done, in simple terms, this is the only way to avoid complete defeat. For example, Iraq threw some ballistic missiles out when they were not yet the top priority targets, and also caused some ** in Saudi Arabia, almost forcing Israel to enter the war, causing a lot of political pressure. In the case of overall weakness, ballistic missiles were the only ones capable of striking the rear, and at that time ballistic missile defense technology was just a concept that had not been proven, so it achieved certain success.

Of course, this is partly due to the fact that Iraq's ballistic missiles were not regarded as a major threat in the initial assessment, and then Iraq's ballistic missile forces were completely wiped out after the attack on the SCUD was concentrated for both political and military reasons.

There's a problem with the onboard oxygen system, and it's fatal. The last time the plane crashed, it was suspected that the pilot was suffocated by lack of oxygen and caused the crash.

If the problem is not solved, it will be resumed to fly, it is not a matter of life, hundreds of millions of aircraft, human lives, and the face of fourth-generation aircraft.

When the return flight will be known only to the Yankees. Maybe there's something wrong.

The F22 stealth technology was cracked by China, not a J20 opponent.

The F22 technology is too avant-garde and should be conservative.

In the future, all oxygen cylinders will be used, and the performance will not be affected.
