At the beginning of September 1997, made a debut flight of the fighter "Raptor" f-22. Despite zlopyhaniya many domestic and foreign experts, the flight characteristics of the aircraft fine, but a few years ago it was finally removed from production. And it's not so much its stunning expensive, but with the mishaps that occur during its operation.

The Blow to taxpayers

f 22 RaptorThe Story that hides a "Raptor" f-22, it is possible to publish in adventure books. It twisted and intransigence of the U.S. Congress, and tantrums developers were forced to combine nesovpadenie, and the excitement for the first flight, and the mysterious death of pilot and permanent restrictions on service loads... the Sum of which was spent on the development of the aircraft, exceeded $ 70 billion, according to official information.

Where they went origins

Technical specification for the creation of new aircraft F-22 Raptor American designers received in 1981, but the customers in the face of the government knew (but not all) that the development in the best case will be delayed for a couple of decades. In principle, by the air force in those years it has received new F-15 opportunities which should be enough for a few years. But because Washington immediately wanted to get equipment that would utterly surpassed both the Soviet and the European. Politicians dreamed of a very versatile aircraft which could operate as a fighter and attack aircraft. How did that happen? You be the judge.

Rebuilding never ends

To control the filling was shown just unimaginable at the time of the claim. So, the onboard computer was supposed to have a capacity of not less than 10 GFlops and memory in one Gigabyte. I must say that the developers have managed to solve such a trivial task using simple the i486. But then the military was waiting for the blow: in 1996, only a year before first flight, Corporation “Intel” reported out of production older models. Meanwhile, the Pentagon initially hoped to receive at least 1,200 aircraft, each of which had 80 (!) processors. Where did they take something? Lockheed Martin has repeatedly tried to “squeeze”, but “Intel” proved a tough nut and didn't want to release extremely outdated equipment in small batches.

And therefore had to rewrite everything for the new CPU. Only of adaptation, according to official reports, had to spend at least a billion dollars. In General, “unlimited time limits” turned out to be pretty damn costly. And this was only the beginning. Indeed, the fifth generation fighter aircraft…

Counting and shed a tear

USAFThe military Themselves dreamed of love, whose cost would not exceed $ 40 million per plane. But the price rose steadily, but because the Pentagon had to reduce their appetites. When, in 2011, was built 187 aircraft (and production was curtailed), it became clear that the cost of one machine exceeds $ 150 million. So the cost of f-22 "Raptor” “surpassed" (and much more) even the price of the F-117 (aka “the Lame Goblin”), who was considered the champion on this indicator. However, this machine still has a lot more positive features than the model 117, which themselves American pilots respectfully called "flying iron".

A Set of contradictions

Hypothetically, as "Raptor" f-22 have not been in a real fight, a plane in the sky is extremely good. From the point of view of the radar visibility it is not so very different from the “standard” machines. From an assault point of view, the plane is just nonsense, because the money can be purchased at least a dozen regular stormtroopers, the cost of maintenance which is a hundred (!) times cheaper.

And yet this is not the result of incompetence of designers. Americans have always made good aircraft, experience in this field they did not take away. Just developers by the time the first flight had to make a machine a whole set of compromises. And this, as you can understand any tech-savvy person, never to anything good does not.

Trail compromises

So, I had to constantly go for poor performance. For example, the "Raptor" f-22 has no exterior pendants for missile and bomb armament that makes him assault the value to zero. It went from that subject to the availability of the suspension of the plane was well visible to radars. How noticeable is a machine for modern systems of radar detection, is not known, as the “battle” using ‘Raptor” to date limited to computer simulation.

But because the whole “filling” is located in the inner compartments. All four of them. Two – one rocket, the other two – two. Moreover, according to the customer's requirement, they had to start in attack and fighter version. This made the creation of a highly complex device that could "push out" of the missile at supersonic speed. And this is done in two stages. First powerful pneumatic actuator literally knock the weapon from the outer compacted layer of air, hydraulics and then throws a projectile at himtrajectory.

fifth generation fighterThe Commanders of the US air force wanted that the response time of this wise mechanism did not exceed 0.2 sec. Here only, despite the Herculean efforts of engineers and scientists, in practice, this value is 0.9 sec. And it's not slowness mechanics: if a missile on afterburner speed to push faster, it disappears. So that the reaction of the plane, shall we say, slow.

It Should be noted that such a surprising start, not all the missiles in all flight modes: if the attack involved more than a simple device. If you do not go into the details, if necessary, firing the bomb Bay opened, the rocket is placed on the guides with them and starts.

Marking priorities

In the end, all came up, so the aircraft f-22 "Raptor" on the drawing boards generally will not go away, but because something has to be sacrificed. Scientists got the task to maximize flight performance. Then the engineers decided to use the engines with variable thrust vectoring, as well as significantly improved the contours of the airframe. For some reason Americans prefer to stay only on the vertical change of thrust (our su-35, for example, can change it in the horizontal direction).

Invisibility on the radar screens put in second place. Unlike “the Lame Goblin”, that is, F-117, they were used so as not to hurt the classic shape of the glider and not to turn the plane iron from the point of view of aerodynamics. Departing from the topic, say that in 1990, when the production of "Night hawk" was hastily collapsed, all the money from this program was inherited by the ‘Raptor”. Theoretically, it is believed that the dispersion of the F-22 Raptor is 0.3 m². From "Goblin" this figure ranged from 0.01 to 0.0025 m². But ‘Raptor” decided to do just the plane, not the flying iron. Simply put, Lockheed Martin at this time decided not to test the patience of the Congress.

However, the normal compromise between stealth and precision bombing did not work out. Even on finding a solution have been spent a lot of money. So, for the sake of ‘Raptor” was created by “smart" bombs targeting GPS. The fact that in small bomb bays of f-22 simply does not fit a normal bomb with active targeting. If you use a “simple” munitions, homing on the target object by laser beam, then all the stealth aircraft is flying down the drain. So the help of the satellite turned out to be almost the only possible solution to this problem.

f 22 raptorIn General, the bomb turned out spectacular: you can fly to a distance of 30 kilometers from the discharge point, the deviation from the target does not exceed 11 metres. Strictly speaking, the missile is rigidly tied to specific coordinates of the earth's surface. So if the purpose of maneuvering to hit its fifth-generation fighter will be able hardly. Which again puts an end to his assault abilities. But that's not the only drawback. To hit “smart" bomb a stationary target, ‘Raptor” must fly literally under the noses of enemy air defense forces. So as an additional load in the bomb bays of the machine load, and missiles, specifically designed to counter air defense.

Assault weakness

It is Noteworthy that the universal f-22 "Raptor", the characteristics of which we understand, do not have special equipment for detecting and tracking ground targets, which again reduces its attack opportunities to a minimum. In General, and not blame designers: initially a similar instrument at the plane was, but it was taken out of the design at the request of the Pentagon, when the cost of the program is absolutely free. To the credit of the engineers from "Lockheed Martin" I must say that at least the basic tools for precision bombing they were still able to save. So, in aircraft has all the necessary options that allow you to quickly and without special losses to mount the necessary on-Board equipment, if it will give good to the higher management.

However, while the primary means of attacking targets on the ground are just the same above mentioned bombs with GPS, the effectiveness of which is great, but only when you work on stationary objects. In General, this is the reason why the ‘raptors’ had not taken any part in the military operations of the USA in the same Afghanistan. Who is there to catch the GPS? So for this reason the arms of the Americans are still the old F-16, adequate replacement which is not yet available.

f 22 RaptorIn General, owing to the war in Iraq, where the U.S. military has met more or less serious opponent, who was aviation, it begs only one conclusion: to use f-22 to war with Third world countries – utter nonsense. Watch flight of this aircraft are almost more expensive than a couple of old f-15s that will perform the same tasks.

Life support System pilot

It May seem that the USAF got the car, which is a set of technical absurdities. In principle, the basis for this opinion is, but in fact, this technique incorporates many breakthrough technologies.That's just they are so “raw”, given that all their benefits – nothing in the face of the problems that they create. The new complex, expensive and capricious in debugging. One of the most characteristic examples is a suit of life support of the pilot. In fact, this “costume” difficulty hardly exceeds space suit.

The System is so fancy that she has to manage using far not the most weak computer. If it fails, there is the option of manually switching the manual control (now the switching is automatic). But already during the first tests in combat units, the command of dozens of pilots began to receive reports from pilots with requests to transplant them c Lockheed Boeing F-22 Raptor to something more appropriate. The fact that entry and exit manoeuvres with strong overload all the pilots experienced severe oxygen starvation, on the verge of fainting. Then the army bureaucracy did not give the complaint any difference. That's just in 2010, another pilot was “weak” and simply fainted at the conclusion ‘Raptor” of the bend. As a result, the car crashed, people died.

It was Later revealed that the system is bleed and discharge air pilot costume poorly designed. More precisely, “tinkering” valve: because of its inadequate operation, the air does not have time normally to bleed, resulting in people simply squeezed the excess pressure. Moreover, the congestion was so strong that it shrank even the pulmonary alveoli. The result is one hundred and fifty machines were at that time in the ranks, had quickly to convert. More than a year ‘Raptors" was strictly forbidden to climb above five thousand meters (if the ceiling is 20 thousands).cost of f 22 Raptor

Conclusions

It is believed that to date, the car seems to be brought to final condition. But it remains an open question - what should I spend this amount of money to develop this aircraft. Hypothetically impeccable fighters can be replaced by a 4++ generation aircraft, and their assault capabilities, the Pentagon and all trying not to remember once again.

However, we should not deceive ourselves: a nasty lesson the Americans had learned well. When the development of the F-35, maneuverability decided to sacrifice it in favor of stealth. The customer then decided that with high level of dispersion of the radio signal such perfect flight characteristics are not so required. However, this time the Americans stepped on another rake, but it is not that... In conclusion, I would like to say that at the present time in full tested our PAK-FA. Most likely, our designers were able to take into account the negative experience of their overseas counterparts and are unlikely to repeat their mistakes.

It Should be emphasized that, despite all its shortcomings, the f-22 Raptor – almost the only Western aircraft capable of performing the famous "Pugachev Cobra". And this is a very bad sign, attesting to the high maneuverability of the machine that is certainly able to compete on an equal footing with our su-37 or later models.

Commissioning occurred in 2005. Total production of 187 aircraft. Lost five fighters.

In conclusion, I would like to reiterate that the ‘Raptor” is a perfect example of negative PR, which is largely spread themselves as us military. Yes, a lot of plane problems of an economic plan, which the Pentagon of attention might not pay. But from a technical point of view, the car turned out very decent. The only real shortcoming – no same multitasking.

At ground targets fighter f-22 "Raptor" to work is not practical, the effectiveness of three or four bombs is clearly insignificant. But in terms of fighting with enemy fighters, the plane must be good, even if in practice this has not been confirmed.

By the way, our T-50 also has a closed internal compartments for weapons and information about the external kit there… So that our American fighter of the fifth generation is clearly similar to each other. It is hoped that in combat a test of their capabilities will not be held. In addition, if all the technical limitations of the ‘Raptor” we should not forget that in modern aerial combat, the lion's share of success – the use of modern missiles. And then the Americans, everything is in order.

arms of the f 22 RaptorFinally, a huge plus programs for f-22 and f-35 (of course) – a movescience and running a brand-new technology. Domestic su-47 «Berkut» has been created and tested with the same objectives.
