The United States conducted the first tests of the version of the turbofan engine F130, intended for installation on strategic bombers of the US Air Force B-52 Stratofortress. According to Defense Aerospace, the development of a new power plant is engaged in the American division of the British company Rolls-Royce.

In the US, tested a new power plant for the bomber B-52




As part of the B-52 strategic bombers modernization program, the U.S. Air Force is considering remotorization of aircraft to extend its life. To date, there are two options for remotorization - the first, which provides for the replacement of standing engines with others (direct replacement) and the second, which provides for the replacement of power plants with their reduction from 8 to 4.

Reportedly, the TF52 engines on the B-33 are very expensive to maintain, and they also have high fuel consumption. During the remotorization of the US Air Force plan to reduce the cost of engine maintenance and expect to reduce fuel consumption.

The F52 engine proposed for installation on the B-130, or rather its version, was developed on the basis of the BR725 power unit used on 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.

Earlier it was reported that during the upgrade, the B-52 will receive a new radar station with an active phased array based on the APG-82 radar used on F-15E Strike Eagle fighter-bomber aircraft.

In addition, it is planned to equip all aircraft in service with digital data transmission channels, displays with digital maps, next-generation avionics, and new radio stations. Also, work will be carried out to increase capacity, the B-52 will be able to carry more missile and bomb loads due to the optimization of the internal space and the installation of new underwing pylons. In addition, the aircraft will be able to use the new high-tech weapon. Earlier it was reported about the development of a new promising roundabout weapon system for the B-52, which will allow carrying precision munitions both at external points of the suspension and in the bomb compartments.

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.

The combat radius of the B-52 is 7,2 thousands of kilometers, and the fermentation range - 16 thousands of kilometers. The aircraft can reach speeds of up to 950 kilometers per hour and carry a bomb load of up to 31 tons.

    When there, urya-patriots, "Beetles" and "Squirrels" from the "hollow" will finally come out? Or for another 30 years ROFAR will be "sea-slumbering" (you can use the image of a character only with the permission of the copyright holder, on the territory of the Russian Federation it is "CD Land Contact" - but I don't have it)?

      smile What a manner of insulting people ... you’ll play out that they’ll pass by your identity in the same way ... The Russian language allows you to hang a hundred or even more different labels on you ... so I recommend behaving decently ... get out of childhood.
      As for the article ... that’s a completely normal desire of Americans to save on servicing expensive equipment ... one F-35 cost the US budget a fabulous amount ... servicing strategic bombers is also an expensive business.

      Do you mean serial production? The squirrel went into series with the Su-57, and the Zhuk radar has so many different modifications, some of which have been in the series for a long time, if you mean the Zhuk-AM, there should be customer interest, apparently the Russian Ministry of Defense considers this radar too expensive and redundant at the moment.
      during the modernization of the B-52, they will receive a new radar station with an active phased array based on the APG-82 radar used on F-15E Strike Eagle fighter-bomber aircraft.

      Our Tu-95MSM has also become more big-eyed.
      The modified Tu-95MS has a "harsher" steel "eyes and ears." The new Novella-HB1.021 radar with a phased array detects aerial targets at a distance of 90 kilometers. “Cut off” surface targets at all for 320. At the same time, “Novella” is capable of detecting and tracking up to fifty objects.

      The electronic “brain” of the domestic “veteran strategist” does not lag behind the demands of the times. A special hit is the digital “glass cabin” SOI-21, which displays all the information directly to the glass in real time.

      A three-dimensional picture of the surrounding world shows the pilot a map of the terrain, approach procedures, weather map, navigation tips. In the dark, the infrared camera system turns on, turning night into day.

      With engines, the Tu-95 is also a pleasant metamorphosis. As before, our giant rises to heaven with four screws. But since 2014, they are rotated by a new modification of the NK-12MVM engine of 15 thousand “horses”. A special “feature” of the motors was the new four-blade propellers AB-60T. These "mills", as they are jokingly called aviators, rotate in opposite directions.

      “Medved” also has a rather economical fuel consumption. Tu-95 motors have a record efficiency of 94% with a screw installation efficiency of 82%. True, their negative side is very loud.

      The overseas “strategist” is capable of the ultimate (driving, that is, without bomb load) range: almost 17 thousand kilometers at an altitude of 16.765 meters. The turboprop “Bear” has more modest figures: 15 thousand kilometers have a maximum range with a practical “ceiling” of 12.000 meters.

        only up there they forgot about metal fatigue.

        Any element has calculated endurance limit values ​​(the highest maximum cycle stress at which fatigue failure of the sample does not occur after an arbitrarily large number of cyclic loads). Fatigue evolutions in the airframe metal structures are detected by flaw detection methods. It is important not to miss the moment when, at loading at the ultimate strength, the stress exceeds the yield strength and deformation of the metal of structural elements from elastic reversible to elastic-plastic irreversible.
        In any case, there is a check schedule (emnip after 5000 cycles). But each element has its own.

        The Americans modernized the most "live" "Lancers" and began to assemble the first B-21 Raider. The Tu-160M ​​does not even have a share of those innovations that are announced in the B-52. The M2 modification also stalled on the assembly of the board "from the warehouse", with the engines not all right yet ... but with everything, in general, you still need to tighten up. It will be good if a series is really launched in 2023 (which is unlikely based on the experience of almost all the latest projects). A series of 50 boards with 2-3 declared cars per year will not be "assembled" until 2030. Parallel assembly - pants will tear.

    Currently, the United States has 76 aircraft of this type ...... I consider it necessary to add, being in service and a couple of hundred for long-term conservation at the Davis-Monten air base. With the possibility within 2 to 3 months of putting everyone in operation.
    Of those in service, only 48 are used, the rest are active reserves. They are serviced, fly by few, and do not participate in any military operations.

    Is this the engine on the Gulf Stream?
    Well yes, economical, but "direct replacement"? It's like the Il-96 or Il-476 (76) with the PS-90, not the 276 or the new 96 with the PD-35 (2027 ???). All the same, without reducing the number of engines.

      This will be the second replacement of engines on the B-52. Now it has the second generation engines. The first were single-circuit.

    I think it will depend on the success of the new bomber development program. If successful, then they simply deliver updated engines from the Gulf Stream, if it drags on, then there are already 4 large engines (which is much more expensive)

    You are right, namesake, when you emphasize that these are machines in service (76). True, I don't quite agree with the numbers. On Davis Montana, of course, there is a fair amount of B-52s on storage, but not a couple of hundred - that's for sure. A significant part was cut at the conclusion of the EMNIP START-1 (or OSV-2) agreement. We cut Myasishchev's Bizons, they cut their own B-52s. Photos of the results of this process are well known.
    The number of B-52, which can be returned to service if necessary is not so large. Now I will not say offhand, but about a dozen V-52N and about 2,5 dozen V-52G. The number of V-1V from storage is less than a dozen ....

    These 48 (?) Are intended for the so-called. "atomic missions". The rest are the so-called. non-nuclear bombers. In general, the figures for July last year in the framework of information exchange on START-3 are as follows

    • Deployed bombers = 13 units. B-2A and 36 units. B-52H
    • Not deployed bombers (the same active reserve) = 7 units. B-2A and 17 units. B-52H
    • Bombers used to test a new type of combat equipment = 1 unit. B-2A and 2 units. B-52H
    • "Non-nuclear bombers" (bombers adapted for WTO use) = 41 units. B-52N

    Our TU-95 bombers also had radars that were used to capture targets when the TU was used as the carrier of anti-ship missiles. Even the goal of the strategist can change, and the radar is by no means an extra piece of aircraft. Moreover, he can use high-precision weapons, including cruise missiles on ships
