Qualcosa è caduto dal cielo ... #-o


A homeowner was left stunned after a large metal chunk of aircraft from an American B-52 bomber plummeted from the skies and landed in her front garden.
The unidentified woman contacted police after hearing a 'loud thud' outside her property in Brailes, Warwickshire, at around 5.30pm last Wednesday.
The villager went outside and discovered the piece had broken from the fighter plane ( :shock: ) and landed in her front garden, narrowly missing her home.
Aviation experts attended the scene and confirmed the debris was part of a giant B-52 bomber which had been based in the county at RAF Fairford, Gloucestershire.

Missione conclusa ... le 'Stratofortezze' rientrano alla base ...
Four B-52s and about 300 airmen returned to Barksdale AFB, La., after a four-week task force deployment to Europe that included training exercises throughout that continent and the Middle East.
The bombers from the 2nd Bomb Wing flew 32 sorties at its deployed home base of RAF Fairford, England, and trained with 13 total partner nations since first deploying last month.

Not only is the photo remarkable because it pictures a rare (not catastrophic) engine mishap, but also because another peculiar feature of the B-52 is clearly visible: the so-called “beauty wrinkles” on the front fuselage of the iconic bomber.
Our readers have noticed these “wrinkles” or “ripples“.
Commenting our post on social networks, many have suggested they may have been a sign of the airframes aging.
However, they have nothing to do with age of the B-52: they are the visual effect of the aircraft’s skin buckling.

Rimotorizzazione ... qualcosa (finalmente) si muove ...
The US Air Force (USAF) released a draft request for proposal to replace the engines of the ageing Boeing B-52H Stratofortress.
The notice brings the B-52H re-engine programme one step closer to kick off.
The service plans to buy 608 commercial engines – plus additional spare engines and support equipment – enabling it to operate the heavy bombers until at least 2050, a 23 April notice says.
The USAF plans to award a contract in May 2021.
The engines are to be delivered over 17 years.

A B-52 assigned to the 2nd Bomb Wing at Barksdale Air Force Base, La., lost an access panel during a May 1 flyover to honor individuals on the frontlines of the fight against the new coronavirus in New Orleans.
Around 10:30 a.m. local time, a hand-sized panel from the Stratofortress became dislodged over New Orleans city limits, wing spokesperson 2nd Lt. Aileen Lauer told Air Force Magazine later the same day.
“The panel landed on private property and was quickly recovered by Air Force personnel, in partnership with local authorities,” she said.

Rimotorizzazione ... si parte ... rilasciata la RFP ...
The Air Force on May 19 issued its request for proposals on the B-52 Commercial Engine Replacement Program, calling for responses by July and a contract award expected in June 2021.
GE Aviation, Raytheon Technologies’ Pratt & Whitney unit, and Rolls-Royce have all said they will compete.
The service, in the RFP, confirmed it wants to buy a total of 608 engines to equip 76 B-52s, each of which mounts eight engines arrayed two each in four nacelles.
For prototyping purposes, USAF will start with 20 engines - 16 for two aircraft plus four spares.
The first contract will be indefinite delivery/indefinite quantity, with production models delivered through 2037.
The B-52 is slated to remain in service through 2050.

Arriva "Laura" ... e i "giganti" sloggiano, per precauzione, da Barksdale ... :shockingzap:
As Hurricane Laura strengthens to a Category 4 storm, Eighth Air Force is moving most of its 47 or so B-52 bombers at Barksdale Air Force Base, La., to other locations and putting base personnel at HURCON 2, the second-highest storm readiness level, rather than evacuating personnel, a 2nd Bomb Wing spokesman said.
Barksdale, which hosts 8th Air Force, Global Strike Command, and about half the Air Force’s B-52H force, is located in northwest Louisiana, almost directly in the path of Laura, which is predicted to skirt the Louisiana/Texas border after making landfall the night of Aug. 26.
The National Hurricane Center predicted Laura will still be at about Category 1 strength, with winds up to 95 miles per hour, when it reaches the vicinity of Shreveport and Bossier City, where Barksdale is located, the morning of Aug. 27.

The 2nd Bomb Wing’s B-52s have returned to Barksdale Air Force Base, La., and operations there have returned to a normal operating tempo just two days after Hurricane Laura swept toward nearby Shreveport and threatened grave damage, a wing spokesman said.
Laura was still a Category 1 storm pushing winds in excess of 85 miles per hour when it passed within a few miles of Barksdale, in northwest Louisiana, but the base itself saw far less fierce winds and only suffered minor damage and flooding, the spokesman said.
Airmen on base took precautionary measures, such as boarding up windows and deploying sandbags in areas prone to flooding during heavy rains.

Three USAF B-52s flew through the Baltic Sea region on Aug. 31, training with aircraft from six nations and flying over Latvia just days after a Russian aircraft reportedly violated NATO airspace to intercept another B-52.
During the Aug. 31 flight, the B-52s, which are deployed as part of the bomber task force at RAF Fairford, U.K., trained with aircraft from Belgium, the Netherlands, the United Kingdom, Italy, Germany, and Portugal, then flew over Riga, Latvia, according to a U.S. Air Forces in Europe-Air Forces Africa release.
A USAF KC-135 from RAF Mildenhall, U.K., supported the bomber flight.

Un altro decennio di miglioramenti consentirà al B-52 ulteriori tre decenni di vita ...
The nearly 60-year-old B-52 will be the workhorse of the Air Force’s bomber fleet another 30 years at least, reinvigorated with upgrades to boost its range, power, sensors, and bomb-carrying capacity.
Once complete, Air Force Global Strike Command’s improvements to its 76 B-52s will provide the equivalent of an extra 22 bombers’ worth of weapon-carrying capacity.
The multitude of upgrades are already well underway and will continue into the late 2020s, providing aircraft built in the 1950s and ’60s - the last B-52 was built in 1963 (*) - with modern engines and radars, new capability to carry more smart weapons internally, new communications and connectivity, and the ability to deliver the most advanced missiles in USAF’s inventory.
B-52s will also remain a key part of the American nuclear deterrent.
The changes are significant enough that the upgraded bombers could be redesignated from B-52H to “B-52H+” or “B-52J.”

In addestramento sul Mare di Barents ...
The latest Bomber Task Force (BTF) mission in Europe occurred Thursday over the Barents Sea as a U.S. Air Force B-52 Stratofortress bomber aircraft conducted integration operations with NATO Allies.
The bomber, assigned to Minot Air Force Base’s 5th Bomb Wing in North Dakota, departed Thursday and flew to designated locations where the bomber integrated with Greek and Norwegian F-16 Fighting Falcon aircraft and conducted aerial refueling operations with U.S. and Turkish KC-135 Stratotanker aircraft.
Upon completion of the missions, the aircraft and crew immediately returned to North Dakota.
Missions like this demonstrate America’s continual global strike and global reach capabilities through the employment of strategic bombers.
The mission originally involved two bomber aircraft, but one aircraft safely diverted to RAF Fairford, England, Thursday afternoon due to a maintenance issue.

Two B-52s flew directly to the Persian Gulf from Barksdale Air Force Base, La., in what the military says is a message of deterrence to Iran.
The bombers, from the 2nd Bomb Wing, took off from their home base Dec. 9 and integrated with other U.S. Air Force and partner nation aircraft during the long-range mission, according to a U.S. Central Command release (*).
The tasking came on a short notice, with the goal of proving the U.S. can send bombers anywhere, anytime.

This summer, the U.S. Air Force expects to have all the data it needs from the three defense companies competing to replace the B-52 bomber’s engines, but it is still “too early to say” when a contract will be awarded, a top general said Feb. 25.
The service is waiting for the three competitors - General Electric, Rolls-Royce, and Pratt & Whitney - to provide more information about proposals each company submitted last year, according to Gen. Timothy Ray, who leads Air Force Global Strike Command.
“The request for proposals is out,” he told reporters during a roundtable hosted during the Air Force Association’s virtual Aerospace Warfare Symposium.
“We should have this summer the answers back from the competitors to be considered. And so then, from that process, we’ll go from there.”

Sono anni che stanno discutendo dell'eventuale ri-motorizzazione dei B-52H ... nel frattempo i costi ...
The total program cost of re-engining the B-52H fleet of 76 airplanes will be about $11 billion, a 9 percent jump over a previous estimate because of more up-to-date data, Acting Air Force Secretary John P. Roth told lawmakers June 17.
Roth told the Senate Armed Services Committee that recent press reports of a 50 percent increase are incorrect.
This new number reflects information obtained from virtual prototyping of the system, along with “a re-assessment of the requirement” and the inherent complexity of integrating a modern, commercial engine onto the “aging platform that the B-52 is,” he said.
The cost increase also takes into account the “realities of buying from the current industrial base,” Roth said.
The Air Force was not immediately able to provide precise numbers, or whether the 9 percent is a base year or then-year cost.

A contract award for new engines for the venerable B-52 bomber is “imminent” and could occur as early as this month, the U.S. Air Force’s top acquisition officials said Tuesday.
The service is set to decide whether General Electric, Rolls-Royce or Pratt & Whitney will produce modified commercial engines to outfit the B-52, which is set to fly through at least 2050.
“We’re starting to wrap that work up. It shouldn’t be much longer,” said Lt. Gen. Duke Richardson, the Air Force’s top uniformed officer for acquisition.

While Boeing provided “information” to the Air Force about which engines were relatively easier or harder to integrate - and what other changes might be required - the company did not make a recommendation of any particular engine, a Boeing program official said.
Boeing will decide how the engines should be placed on the wings and whether to mount them in twin-engine nacelles, as the TF33s are mounted now.
The official said the disused infrared blisters on the aircraft’s nose will be removed to improve airflow to the new engines, restoring the aircraft’s original profile.
In addition to the B-52’s engines, the Air Force is planning to replace the bomber’s radar, communications systems, and much of the cockpit

Rimotorizzazione ... ha vinto Rolls-Royce ... 8)
The Air Force has selected Rolls-Royce North America as its contractor for the B-52 Commercial Engine Replacement Program, or CERP, which will supply new F130 powerplants for all 76 of Air Force Global Strike Command’s B-52H bombers, the Pentagon announced Sep. 24.
If all options are exercised, the work is worth $2.6 billion.
The F130 engine is flying on the C-37 transport and E-11 BACN (Battlefield Airborne Communications Node) aircraft.
The first part of the indefinite quantity-indefinite delivery contract is worth $500.9 million.
The contract calls for Rolls to supply 608 engines, to equip 76 B-52s with eight engines each, with manufacture and installation to be completed by Sept. 23, 2038.
Rolls said the actual number of powerplants, including spares, is 650.
The Air Force did not say when the installs will begin.
The engines will be built at Rolls’s Indianapolis, Ind., facilities, where the company said it has invested $600 million in an “advanced manufacturing campus.”
The work will require 150 new hires, the company said.
The contract value is substantially below initial estimates, which ran as much as $10 billion for the CERP.

I nuovi motori per il B-52H ... parla Rolls-Royce ...
To win the B-52 Commercial Engine Replacement Program, Rolls-Royce digitally “built” the bomber’s wing with the company’s F130 engines installed to demonstrate its advantages, Rolls-Royce North America President and CEO Tom Bell said in an online seminar.
“We digitally integrated that engine into the pod, into the pylon, into the wing, and dynamically modeled the entire system of operation to model for the customer exactly how efficient that product would be on that wing,” which was “designed … in the 1950s, early 60s,” Bell said in a streaming discussion with Defense One.
He also revealed that Rolls’ proposal calls for modifying the wing “as little as possible” in order to reduce risk.
With the digital model, “We were able to demonstrate for the Air Force … how our engine, and this approach, would lower their integration risk, so as to integrate this engine efficiently, affordably, and on schedule,” Bell said.
The digital model also demonstrated how maintenance could be accomplished more easily, he said.
