In service until the XXII century: General Electric introduced a program for replacing engines for the B-52

The eight-engine B-52 Stratofortress first flew into the sky in 1952, served in Vietnam and continued to work as a key asset of the U.S. Air Force during the Cold War. Although the last aircraft was built in the mid-1960s, the aircraft were constantly updated, and it is currently planned to keep them in the Air Force fleet for about another 20 years. But the manufacturer is ready for a longer period.

That would be a pretty good run, but General Electric believes the B-52 can be upgraded and will continue to serve in the 707st century if the Air Force cooperates with them. GE has proposed a reengineering program that will replace the current Pratt & Whitney engines, similar to those used on the Boeing XNUMX, with some that also have history use in commercial aircraft.

Thus, instead of completely replacing the B-52 in 2040 with the new B-21 Ryder invisible bomber, the updated B-52 could supplement its younger brother for up to 70 years. This would allow the B-52 to celebrate the 150th anniversary of service in 2102!

But neither the Air Force nor GE are simply seeking to preserve the legacy of the B-52. Both see this reengineering option as a way to reduce costs, simplify maintenance, increase reliability and expand fleet capabilities.

In April, the Air Force requested bids to transfer the B-52 from its current engine to an updated engine. Therefore, GE views its proposal to extend the aircraft's life beyond 2040 as a competitive advantage for this contract, as the company goes head-to-head with Rolls Royce and Pratt & Whitney.

GE also offers the Air Force a key strategic approach - the ability to implement the same systems used by commercial aircraft. This tactic eliminates a number of potential supply chain problems and provides an organic source of maintenance and reliability information.

So yes ... but that is precisely why all airplanes "fly on static" constantly and there, in the process of "constant operation", all loads and possibilities for further operation, including time periods, are already determined.
Research is carried out, bulletins are issued, improvements are made, and on the basis of their implementation, new calendars and operating resources are "published".

Even as it allows. The planes are still of old solid construction, and they fly without overloading the glider. The B-52 is roughly like the Douglas DC-3 / S-47 (which still fly in some places, and not museum exhibits, but workhorses), an absolutely indestructible device during normal operation.

Many years will pass from the first flight to adoption. And by analogy with the F 35, it will noticeably rise in price from the initial price and will get rid of "childhood diseases" for a long time. Which, in turn, will delay the time of full commissioning.

There was an attempt to replace the engine from the Boeing-4 with the 747th engine, but ... it did not work. It seems that during the first test the engine came off - excess power.

[Pavel57]

We have no alternative to the NK-12, without them the Tu-95/142 will not fly.

[ved_med12]

Sorry, what is wrong with the NK-12?


Currently, Tupolev PJSC is conducting the next modernization of the Tu-95. As Russian Defense Minister Sergei Shoigu said on December 24, in 2020 the Russian Aerospace Forces will receive six updated Bears. The aircraft will be equipped with modern navigation and radio systems, as well as electronic warfare systems.

Together with the Tu-95, domestic engineers repeatedly improved the NK-12. Modernization involved the replacement of materials and control equipment. As a result, the power of the power plant in take-off mode increased to 15 thousand liters. from. At the same time, the engine retained the main advantages laid down by Kuznetsov: reliability, efficiency, unpretentiousness in operation.

Quote: ved_med12

Sorry, what is wrong with the NK-12?

First, is the technology of its production (and components) preserved? Not sure. And even if it has survived, will it be able to survive for another, say, a quarter of a century? After all, orders are countable, and the market economy and planned unprofitable business does not tolerate.
Secondly, the nacelles are part of the wing. So, it will not work to change to another motor with different dimensions, unlike the B-52, in which the motors are suspended on pylons. And the same severely limits the possibility of upgrading the existing motor. And making a new wing, I'm sorry, is almost like making a new aircraft with 1950s technology.

[orionvitt]

Quote: Nagan

If the technology is there, then losing it is problematic, especially when the country did not experience industrial decline, as in the United States. It was in Russia that they could have lost something in the 90s, and then, if something is needed strongly, the technologies are restored without problems. It is only for the Americans how to transfer the production of something to other countries, so the technologies are perfectly preserved and everything works. And how to reproduce what once supposedly happened, so the technologies are suddenly "lost". I'm talking about the most sensational, about the lunar program, the "unsurpassed engine" F-1 and the "unsurpassed rocket" Saturn 5. So to the omen.

At 89 I moved to the assembly shop for NK12, 4,2, and 3 series, even then the power was 15 thousand horses, and yes, on the MP engine, the box of aircraft and units was changed on the MP engine, for large generators and something there on the strapping, Yes, I remembered and the compressor blades had a different coating

For your reference. Gas turbine marine engines, D-18 engines for An-124, have never been produced in Russia, Marine diesel engines, in the majority, were also produced earlier in Ukraine (Tokmak). So, all the documentation for technological processes, all these products remained there and in Russia, had to be developed anew. As for helicopter engines, everything is fine here, since they were originally developed in Russia and are now perfectly produced, for example, in Gatchina. You, before yelling that everything is lost, first familiarize yourself with the topic. The production of IL-76 was transferred from Tashkent to Ulyanovsk without any problems, and everything is fine.

We flew. But where, how far and why, the question. Where is it all, if nothing better has been invented so far? The entire American lunar program consists of only logical contradictions.

Well why. We put corner reflectors on the moon. (And they started tracking them half an hour after installation). They brought several hundredweight of lunar soil. Rovers, flag, parts of lunar modules are still there.

[orionvitt]

Quote: 3danimal

To put corner reflectors, people do not have to fly there.

They brought a few centners of lunar soil

Where is he? And with a rover, generally a joke. Until now, even in orbit, every gram of the payload is considered. And here, to the moon, think about it, not to the neighboring area, but to the moon they dragged almost a ton of ballast to arrange a ride on the camera on the moon. I don't know about you, but you can't call me gullible. In addition, technologically, even now, a man's flight to the moon is very problematic (or even impossible at all), and even 50 years ago, so in general.

[3danimal]

There was a huge supply of delivered weight. You won't go far on foot on the moon, I had to take it.

But such a thing as design fatigue, and first of all, the glider of the Senate and the Congress of the United States will be canceled by a decree? Why not leave the B3000 in service before the year 52? ??

[Zeev zeev]

As part of the Black Sea Fleet there is still the rescue ship "Commune" (it seems, I can be wrong with the name), since it was built in 1913. And nothing like that, cheerful. An airplane is certainly not a steamer, but it can also serve for a very long time.

[Thrifty]

Zeevzeev, this is an inappropriate comparison, for I have never seen a flying steamer in my life! They have different tasks and functions, different technical operating conditions! "Kommuna" is a rescuer, it will not leave the port with an overload in bad weather, and then a combat aircraft, strategist, will give an order, and fly, regardless of the weather. ..

[Grazdanin]

And the B52 does not fly at 3 speeds of sound. It originally incorporated increased reliability. With normal passage THEN there will be nothing.

[Thrifty]

Citizen, he will not give one supersonic, will crumble from overloads. There will be nothing with him if he has been standing in the hangar all these years, and no one has succeeded in repealing the laws of physics! A scam is a bonanza, having the B52 in service until the next century.

[Zeev zeev]

"Dakotas" still fly beautifully, and the last of them was released in 1945. Likewise, the B-52 is not an airplane that flies with high G-forces and at very high speeds.

what kind of modernization was requested
so indecent a lot
that somehow it doesn’t look too defiant only with a period of further use of 70 years.

Sophisticated technology does not become obsolete by any single factor, but by many factors at once. The engines will be replaced with modern ones, but there will be a bunch of everything that will not correspond to the time.

Well, or for fairy tales about 2102, spend a dozen lard for modernization (draw a project there, paint it in real life, remove cartoons, share the remaining 90% of the dough), and then - this is the handsome B-21, and the B-52 is expensive for him, all of a sudden! !!, 70 years old ... write off, only write off.
