Tempo scaduto ... non sarà più possibile presentare ricorso nei confronti di Rolls-Royce ...
The deadline for lodging protests against the selection of Rolls-Royce North America to provide new engines for the Air Force’s fleet of B-52s has passed, and none have been lodged on the Government Accountability Office’s docket.
“The deadline passed at [close of business] Monday, Oct. 25,” an Air Force source said.
The companies had 10 days after receiving a debrief on why they were not selected to make it known if they planned to protest, and that has not happened.
Rolls-Royce won the B-52 Commercial Engine Replacement Program, or CERP.
The contract, announced Sept. 24, is worth $2.6 billion if all options are exercised.
The company will build 650 of its F130 powerplants, now flying on the C-37 transport and E-11 Battlefield Airborne Communications Node aircraft, for installation on all 76 B-52Hs, each of which will receive eight engines.

Dopo i motori, tocca ora al sistema di generazione dell'energia elettrica ...
Collins Aerospace, part of Raytheon Technologies, will upgrade the B-52 bomber’s power generation system, the company said .
The improvements will help boost the B-52’s range while reducing its carbon footprint, Collins reported.
Boeing is the Air Force’s integrator for B-52 modernization, including the re-engining of the bomber with new powerplants being supplied by Rolls-Royce North America.
Boeing selected Collins for the work on the electrical power generation system (EPGS), according to a Collins release (*).
The EPGS will be based on “industry-leading commercial technology” and will “contribute to the Air Force’s goal of 30 percent improvement in fuel efficiency for the B-52, along with a decrease in carbon dioxide emissions,” the release said.

"On the road" ...
Qualsiasi riferimento a Jack Kerouac è puramente casuale ... ;)
A retired U.S. Air Force B-52H Stratofortress nicknamed 'Damage Inc. II' was recently taken out of storage at the 309th Aerospace Maintenance and Regeneration Group's 'boneyard' at Davis-Monthan Air Force Base and disassembled before beginning its journey eastward across the country to be partially reassembled for research and development purposes.
Now the stripped-down 'BUFF' is on the road and drawing huge amounts of attention.

I nuovi motori per il B-52H ... il lavoro è finalmente avviato ...
Forty years since the Air Force first started thinking about replacing the eight engines on the B-52, the job is finally underway.
The re-engining is the centerpiece of an upgrade that will keep the Stratofortress operationally relevant for another 20 to 30 years.
The contract for the B-52 Commercial Engine Replacement Program (CERP) was awarded last fall and the program is moving forward quickly.
Two new F130 engines have been built and if development and testing proceeds as planned, the first re-engined B-52s will be operational in about five years.
“All the things are in place that are really defining what the B-52 looks like … into the 2030s,” said Brig. Gen. John P. Newberry, program executive officer for Air Force bombers.
He said upgrades include “new engines, a new radar, Advanced Extremely High Frequency and Very Low Frequency communications improvements, data link updates and cryptologic improvements, as well as several smaller efforts.”

Brutte notizie per il programma di ri-motorizzazione dei B-52H ...
I costi per la sua realizzazione sono saliti in maniera vertiginosa e, come al solito, è già partito il consueto gioco allo "scaricabarile" fra le parti in causa ...
The cost of the B-52 re-engining program has increased 50 percent because of integration issues, according to revelations in a House Armed Services panel hearing.
Air Force acquisition executive Andrew P. Hunter acknowledged the B-52 Commercial Engine Replacement Program (CERP) price hike as voiced in a question from Rep. Rob Wittman (R-Va.) in testimony on service modernization.
“We currently believe there is cost growth from our design work that we did originally through the middle-tier acquisition program to what we anticipate we’ll be looking at [in] Milestone B,” which evaluates readiness for entry into the engineering and manufacturing development phase, Hunter said.
The B-52 CERP has been conducted as a middle-tier acquisition program to get underway rapidly and develop a prototype system but is now moving to a “traditional” program, and the Air Force is firming up the costs it expects to pay, Hunter said.
The cost increases have more to do with integrating the engines on the B-52, which is a Boeing effort, and has less to do with the engines themselves, which will be built by Rolls-Royce, he added.
“I want to emphasize that a lot of that engineering work is actually inside the airplane, on the support struts, to which the engines attach, versus the engine itself, which is largely a commercial engine that already exists,” Hunter said.
The engine needs only “a modest number of modifications,” he said.

Insieme ai prossimi aggiornamenti di motori e radar il B-52 riceverà anche una nuova designazione ... "J" o forse "K" ...
The B-52H will be redesignated the B-52J or possibly B-52K when it gets a new radar and new engines, but the Air Force hasn’t yet decided what will constitute the new B-52 variant, according to Col. Louis Ruscetta, senior materiel leader for the program.
The program has also developed a new estimate of what the re-engining will cost and is about to submit it to Congress, as directed under last year’s defense bill, but Ruscetta said reports of a 50 percent overrun are far overstated.
In fact, he said he sees no overruns on the horizon.
The radar and engine program represent “the largest modification in the history” of the B-52, Ruscetta told reporters at Air Force Materiel Command’s Life Cycle Industry Days conference in Dayton, Ohio.
The change from B-52G to B-52H in 1961 was mainly the switch to the TF33 engine, but the new package includes radar, engines, communications, pylons, cockpit displays, and the deletion of one crew member station, meaning “it makes sense” to have a new designation, Ruscetta said.

Una nota a margine ... mercoledì scorso è stato riproposto su Rete 4, nella fascia pomeridiana, il film "La veglia delle aquile" (in originale "A Gathering of Eagles").
A parte l'evidente aspetto propagandistico della pellicola, il suo lato interessante è che viene mostrata quella che era la vita in un reparto da bombardamento strategico del SAC, dotato di B-52G armati di missili "Hound Dog", nell'anno 1963, immediatamente dopo la crisi dei missili di Cuba.
Impressionante questa sequenza ...

Qualcuno di voi l'ha visto?

Oggi ho potuto notare alcuni particolari che, nel corso della precedente visione, mi erano sfuggiti.
Per esempio, nell'ufficio del Col. Caldwell, i modellini dei missili "Thor" e "Titan 1" ... e c'era persino quello di un ALBM "Skybolt" ...

Senza contare che le riprese aeree erano, a dir poco, spettacolari ... come erano di estremo interesse quelle girate all'interno della base degli ICBM "Titan 1" ...

Di nuovo presenti in Europa ...
Multiple B-52 bombers from Minot Air Force Base, N.D., arrived at RAF Fairford, England, on Aug. 18 as part of a bomber task force mission in Europe, U.S. Air Forces in Europe announced.
“These Bomber Task Force missions across Europe provide a great opportunity to improve our combined readiness, promote interoperability and demonstrate our global power projection alongside our Allies,” Gen. James Hecker, commander of USAFE-AFAFRICA, said in a statement.
“Our ultimate strength in the European area of operations is a joint-force lethality - our ability to train and operate with our Allies and partners as one layered, capable and credible combat team.”

Articolo sponsorizzato da Rolls-Royce North America ...
No less unique is the B-52, and Rolls-Royce continues to evolve engine capabilities.
Engineers work to improve the propulsion, and to deliver more electrical power to support emerging systems.
“These advanced electronic systems that are important for survival in engagements with the enemy, the systems that are needed to put precision fires on a target - all of that requires additional power,” Roberson said.
“We are constantly improving, constantly upgrading and advancing to provide what the Air Force needs to conduct the modern fight.”
Rolls-Royce is at the heart of an effort to keep the B-52 Stratofortress flying until it approaches the century mark.
To do that, Rolls matched the proven engines from its business-jet business to the rigorous requirements demanded of a long-range bomber.
Advanced engineering made that easy.
“The ability to digitally manipulate the data that we have on our engine made a big difference in the competition,” Roberson said.
“Suppose a question came up: ‘What if we needed more power for this or that?’ Our ability to digitally analyze the B-52 allowed us to very accurately predict what we could or could not do, and what the impacts and potential cost implications would be. All of that allowed us to be very precise and responsive both to the Air Force and to Boeing.”
