US Air Force intends to announce a tender for the supply of new engines for the B-52H

The US Air Force intends to select a supplier of new engines for the strategic bombers B-52H Stratofortress for their remotorization program. A tender for new engines will be announced shortly, Flightglobal reports.

The winner of the supply tender should be determined no later than May 2021, following which it is planned to purchase 608 new engines for installation on bombers and an unnamed number of spare ones. All engines must be delivered within 17 years after the conclusion of the contract.

The remotorization of the B-52N should extend the life of American strategists to at least 2050.

As previously reported, the US Air Force is considering two options for remotorization - the first, which provides for the replacement of standing engines with others (direct replacement) and the second, for the replacement of power plants with their reduction from 8 to 4. As stated, the TF52 engines currently installed on the B-33H are very expensive to maintain, and they also have high fuel consumption.

In September 2019, the USA tested the version of the F130 turbofan engine. According to the statement of the developers from the American division of the British company Rolls-Royce, the engine is intended for installation on B-52 Stratofortress strategic bombers.

The F130 engine, or rather its version, is developed on the basis of the BR725 powerplant used on the Gulfstream G650 business jets. With less fuel consumption, it is able to develop thrust up to 75,6 kilonewtons, which corresponds to the thrust of TF33 B-52 engines.

The B-52 Stratofortress is a multi-functional heavy ultra-long intercontinental strategic missile bomber that has been in service with the U.S. Air Force since 1955. It was developed in the 50s, but is still the main long-range bomber aircraft. aviation US Army. Currently, the United States has 76 aircraft of this type, the average age of which is 50-55 years.

A long story on the plane! It no longer smells like mothballs, but the dust of centuries!
However, an airplane is flight-worthy or flight-unsuitable, it doesn’t happen otherwise.

[orionvitt]

Especially if you take into account

extend the life of American strategists until at least 2050.

That creates a confident belief that the progress of mankind has stalled. Nothing but information technology has evolved over the past seventy years. Neither in aviation, nor in space technology, nor in the automotive industry, in anything. They invent only new materials and each time, gradually improve the old. But there is nothing fundamentally new, breakthrough, capable of radically changing the world.

[voyaka uh]

"there is no breakthrough, capable of drastically changing the world." ///
----
In what sense is it "to radically change the world"?
Explain what do you mean?

[orionvitt]

It's very simple. For example, fire and iron changed the ancient man, the invention of the sail, changed the history of human development in the corresponding period. Gunpowder changed wars dramatically. The steam engine, made the entire 19th century, the internal combustion engine, the entire 20th (which we still drive) Since the 50s, there is nothing radically new, except computers. The technique stopped. It is improving, there are no objections, but nothing new. It is possible to call the 21st century, the century of information technologies, I admit it. But to increase the service life of the aircraft, up to a hundred years (one hundred !!!!), in our time, when from each iron one can hear about "unprecedented progress", literally in all spheres of our life, it is somehow strange. Here, as they say, either a cross, or pants. I repeat, there has been nothing since the 50s of the last century that would make our life more comfortable (except computers and the Internet)

It depends on who’s concept. Development does not imply the destruction of the world. But the idea of ​​dominance in all areas (to be the chief), very much.

And there is a gla / v / nyuk on the planet, with a pack of its gla / v / nuances.
Because everyone is arming up to ... at the very most.

[dzvero]

And after all, no one expected that both the B-52 and Tu-95 would remain in service for so long. None of the "heirs" has managed to completely oust them "for retirement".

[Sky strike fighter]

The B-52 Stratofortress is a multi-functional heavy ultra-long intercontinental strategic missile bomber that has been in service with the U.S. Air Force since 1955.

The remotorization of the B-52N should extend the life of American strategists to at least 2050.

As they say 100 years at lunch. The release was completed in 1962, a year after the launch of the first man (Gagarin) into Space.

[dzvero]

About the fact that Yuri Gagarin was the first in space I know
I'm talking about something else. There were Hustler, Valkyrie ... it was supposed to replace the B-52 by the end of the 60s, but it did not grow together. Even B-1B and B-2 could not; the first one seems to be written off too. And now we get an interesting oil painting. Their Air Force flies on machines developed in the 50s and 70s. The newest rappers - somewhere around 150. 35th is already over 500, but something does not replace 15th, 16th and 18th. It turns out that with beautiful presentations, the Americans drove themselves into ..... (insert a word if you wish). So you have to keep the "oldies" in flight condition. They say that there already a grandson flies on his grandfather's plane.

[Sky strike fighter]

It’s just that Americans are practical. They leave what they need to do. And all these numerous know-how projects for the most part have not passed the test of time. They turned out to be roads or narrowly specialized and left them armed with reason. Besides, what are really new ideas now in addition to stealth technology on the same B-21, F-35?

[dzvero]

In practicality, they can not refuse.
I don’t know about new technologies. My personal feeling is that modern jet aviation has hit a kind of "ceiling" like piston in its time. But then there was a landmark, and now ... hypersound? spaceplanes? If there is no breakthrough in fundamental science leading to a qualitative leap in designs, then we will witness small improvements presented as a huge achievement

[Sky strike fighter]

The Americans are developing the SR-72. We, in theory, should take care of creating and putting into service the Mig-41. The ability to work in space, higher speeds are gradually coming to the fore. This is the future.

[voyaka uh]

F-16s are constantly being written off. Their squadrons are disbanded
and are replaced by F-35 squadrons.
F-18 begin to write off gradually,
but so far partially supplemented by new ones. F-35S only three squadrons.
Harriers retired and replaced with the F-35V.
All bombers plan to replace one type of B-21.

[dzvero]

This is, in general, understandable. Light and heavy fighter concept. But the F-22 is no longer being produced. The F-35's "novelty rate" is off the charts, which makes fine-tuning the aircraft very profitable for the manufacturer, but a nightmare for the Air Force, despite its enormous potential. Is this why they are in no hurry to part with the F-15 and the last F-16?

[Sky strike fighter]

Even the USA cannot afford to replace all aviation with 5th generation fighters, although they are striving for this. Besides, the F-35 pluses are only in long-range combat with strong rivals, but are there many such fights now? No. F- 15 and F-16.

[muham]

Quote: dzvero

F-22 is no longer produced.

And why, excuse me, is it still to be produced?

[dzvero]

So, in theory, the F-22 is a fighter, and the F-35 is multifunctional. If tomorrow the United States removes all 15, 16 and 18, then it will remain with 180 "clean" fighters to gain superiority. It all looks strange.

[muham]

Quote: dzvero

Everything is strange to look.

IMHO, on the contrary. Count how many fighters in the world are able to withstand the US team. So they counted. Netuti. And therefore there is no point in producing.
What’s what, but you won’t refuse practicality.

[voyaka uh]

"Isn't it why they are in no hurry to part with the F-15 and the last F-16?" ///
------
Hitch only with the replacement of the F-15. F-22 is not enough (125 in the ranks), and the new
There is no high-speed interceptor fighter.

[Liam]

All the recent conflicts over 40 years stubbornly show that 90% of the work of aviation is on the ground. There is no particular interception.

[voyaka uh]

If something is missing for a long time, it cannot be concluded that it will not.
Aerial fights are rare lately, but they are quite

in front of a stealth aircraft, imprisoned for sonication, like the F-35

[Liam]

What the Americans have now is enough with a margin for any potential adversary in the present and foreseeable future. High-speed stealth fighters do not suddenly appear out of thin air and the Amers have enough time to develop a new f-22 or release a modification of the f-35 tailored for interception. With what the opponents now have, the unmodified f-35 can easily cope with it, however. Your pilots (and that's all others flying on f-35) are rather unanimous in this

[Grigory_45]

Quote: voyaka uh

F-16s are constantly being written off.

on a global scale, this is completely not noticeable. The machine lasted 40 years and another 20 years flies. If the variations on the MiG-21 are still in order.

Quote: voyaka uh

F-18 begin to write off gradually

if only the F / A-18 Hornets. Supers produce and purchase (already Block 3), and so far he has not seen a real replacement. Although the aircraft is also not new - Super Hornet began to operate 20 years ago.

Quote: voyaka uh

All bombers plan to replace one type of B-21

from this venture the same thing can happen as from attempts to replace the fleet of bombers, first with B-1, then with B-2. Just like in the USSR, they tried many times to replace the temporary version of the Tu-95 with something else, only now it is still flying, and almost all of the successors are in oblivion.

[Sky strike fighter]

I’m seriously looking at Kuzya. I hope to fix it in a couple of years.

Four steam boilers for the heavy aircraft-carrying cruiser Admiral Kuznetsov being repaired will be delivered from St. Petersburg to Murmansk.

As TASS reports with reference to the procurement materials for the Zvezdochka Central Station, the delivery of the boilers is planned from mid-May to June.

"To provide transportation along the route the city of St. Petersburg - the city of Murmansk, four sets of boilers KVG-4 in the period from the 2020nd decade of May 2020 to June 35. The initial contract price is XNUMX million rubles," the procurement materials say.

[Sky strike fighter]

The RD-180s are single-use and do not affect the combat effectiveness of the U.S. Air Force launched them and forgot about them. In addition, the Americans had no alternatives, only recently appeared Space X.

[Antokha]

Unfortunately, the level of our engine building is still in the way. Till. Let's see what will happen after PD-14. If the PD-35 is done quickly and efficiently, then the PD-16 or 18 for Carcasses and Sludge 96-400, we can say that we are back. Even more than that, they got to where the USSR was not.

even if it is hypothetically assumed that Russia was invited to participate in a tender for the supply of engines for bombers, what can we offer? Incredible friends have better motors than ours.
But for now, with aircraft engine building, it’s somehow not very good. There are programs, but there is no real motor

[Undecim]

The second option was removed from the agenda two years ago due to the large number of necessary changes in the design of the airframe and equipment.
Four options are currently under consideration, one each from Rolls-Royce and Pratt & Whitney and two from General Electric.

[Sky strike fighter]

I think Rolls-Royce is in flight. The United States will not want the B-52H to fly on British engines. Pratt & Whitney will most likely win the tender.

[Undecim]

You can think of anything. The American strategic reconnaissance UAV RQ-4 Global Hawk, E-11 BACN (Battlefield Airborne Communication Node) and Lockheed EC-130H Compass Call - EW aircraft fly on Rolls-Royce engines.

[Sky strike fighter]

But what about the slogan America first of all? I do not believe that such a bold contract will be given to the British. It will be difficult for the British to fight with the American lobby of the US military-industrial complex.

[Undecim]

You own both the situation in the American military-industrial complex and the level of Motor Sich technology. The widest profile, take off my hat.

the United States and Britain have very great cooperation. In the same F-35 enough British developments.

On the contrary - removed from the agenda since replacing 8 with 4 will be cheaper - you won’t get much done.
Moreover, you will not save much in the future with further modernization.

Crumbled on the fly? Since 1961, there have been 11 accidents with this "crumbling bomber". And in two fires on the ground, in one - the loss of the engine. Here is a "crumbling" plane. And yes, in this case, this is an option to increase combat effectiveness, and not drank. In the same way, we can say that we have any modernization - drank. Although we perceive each modernization as an increase in the combat readiness of our forces. But the enemy is the Americans. they are initially not capable of anything. This position, like yours, is called the "ostrich position". When it is easier not to believe that any modernization of the enemy means an increase in combat readiness. It is easier to believe that it drank, and what we do - "has no analogues in the world"
