During the Paris Air Show this week, German government officials met with Lockheed Martin to talk about the F-35 Joint Strike Fighter, a source connected to the program told Defense News.
It is not uncommon for potential customers — including Germany — to engage with the defense industry on a number of platforms or technologies, nor does the meeting indicate a significant step forward in the process of selling the F-35 to Germany, the source said.
However, the air show marked the first time the German government and Lockheed had ever discussed the F-35 specifically, albeit in an unclassified setting, he said.

Once Raytheon gets approval from the Pentagon to integrate its GBU-49 guided bomb with the F-35, it will take only a couple months to wrap up the necessary testing, a company official told Defense News on Thursday.
The U.S. Air Force, and more recently the Marine Corps, have identified Raytheon’s GBU-49 as the quickest way to give the F-35 the ability to prosecute moving targets.
Currently the F-35’s ability to strike moving targets is somewhat limited, requiring the pilot to manually direct a GBU-12 to its destination.
The Air Force has since issued a request for information seeking information about precision-guided munitions that would allow the F-35 to hit moving targets — potentially broadening its search into a competition.
However, Mike Jarrett, Raytheon’s vice president of air warfare systems, believes the service will ultimately opt to sole source the GBU-49 from Raytheon.

Elbit Systems and Harris will replace the head-down panoramic display system for the Lockheed Martin F-35 after 2019, the companies have announced.
Lockheed selected Elbit’s US-based subsidiary to begin developing a new large-format, touchscreen display for the F-35 cockpit.
Separately, Lockheed awarded a contract to Florida-based Harris to develop a new computer processor for the display.
The selections were made as part of Lockheed’s Technology Refresh 3 (TR3) effort for the F-35, which is installing new electronics in the 16-year-old fighter fighter programme.

Intanto ..... dal sito 'Contracts' del DoD (July 7, 2017) .....
Lockheed Martin Corp., Lockheed Martin Aeronautics Co., Fort Worth, Texas, is being awarded a $5,577,714,486 modification to a previously awarded F-35 Lightning II low-rate initial production (LRIP) Lot 11 advance acquisition contract (N00019-16-C-0033).
The LRIP 11 contract contains requirements for the Air Force, Marine Corps, Navy, international partner nations, and foreign military sales (FMS) customers.
This modification provides for the procurement of 74 fiscal 2017 aircraft, comprised of 48 F-35A aircraft for the Air Force, 18 F-35B aircraft for the Marine Corps, and eight F-35C aircraft for the Navy and Marine Corps.
In addition, this modification adds funding to previously awarded fiscal 2015 and 2016 aircraft contract line item numbers for the U.S. Services.
Work will be performed in Fort Worth, Texas (55 percent); El Segundo, California (15 percent); Warton, United Kingdom (10 percent); Orlando, Florida (5 percent); Nashua, New Hampshire (5 percent); Baltimore, Maryland (5 percent); and Cameri, Italy (5 percent), and is expected to be completed in December 2020.
Fiscal 2015, 2016, and 2017 aircraft procurement (Air Force, Navy, and Marine Corps) funds in the amount of $4,491,634,930 will be obligated at time of award, $275,641,724 of which will expire at the end of the fiscal year.
This modification combines purchases for the Air Force ($3,428,766,751; 61 percent); Navy ($1,444,492,090; 26 percent); and the Marine Corps ($704,455,645; 13 percent).
An undefinitized not-to-exceed contract modification to fund procurement of 50 F-35 Partner and FMS aircraft for $2.2 billion is anticipated within the month of July 2017.
The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity.
Il commento di DefenseNews .....
The Defense Department has awarded Lockheed Martin a $5.6 billion undefinitized contract that will allow the company to continue work on the eleventh lot of F-35s.
The F-35 joint program office still intends wrap up negotiations on a final contract by the end of the year, but making an interim award was necessary because of “complex production lines and supply chain dynamics,” JPO spokesman Joe DellaVedova said in an emailed statement to reporters.

Il rallentamento del ritmo degli acquisti da parte dell' USAF ha provocato una crescita del costo generale del programma .....
The F-35 program’s cost grew $11 billion in base year 2012 dollars because the Air Force has decided to buy the jets more slowly, the F-35 Joint Program Office reported late July 11.
The increase, reflected in the Pentagon’s periodic Selected Acquisition Reports, was “largely driven by the adjustments made to the US planned production profile,” JPO Program Executive Officer Vice Adm. Mat Winter said in a press release.
“The Air Force reduced its maximum annual rate of aircraft procured from 80 per year down to 60 per year, which extended the planned purchases by six additional years,” from fiscal year 2038 to FY ‘44.
The stretch-out caused “a slight uptick” in unit recurring and program unit flyaway costs, the JPO reported, although “these costs have been partially offset” by recent “block buy” arrangements with foreign purchasers, actual contractor costs, and exchange rates.
The flyaway costs “continue to decline and remain below SAR estimates,” the JPO added.

A substantial portion of the jet’s surface was burned, according to multiple sources familiar with the incident.
Technicians will not know the full extent of the damage until they open the aircraft and examine interior components..
The root cause of the incident is unclear at this time, but initial assessments point to a tailpipe fire due to strong tailwinds as the engine was starting, the sources said.
This can happen after an aborted start if there is excess fuel left in the exhaust duct.
It was descried as analogous to a gas grill left on too long before lighting.
The wind records from Mountain Home back up this assessment, showing that the event happened close to the maximum wind and gust speeds of the day at 37 mph and 45 mph, respectively.
The wind was northwest to west-by-northwest all day.

Non sono mai stato un accanito sostenitore di questa macchina, però occorre dire due parole su questo incidente. Qualsiasi motore all'avviamento non è in condizione ideale se c'è forte vento in coda, con rischi maggiori di hot start. Certo poi i sistemi di gestione del motore (FADEC e simili) hanno incorporate delle routine di gestione del motore in caso di avviamento con vento in coda, in modo da non fare danni e ottimizare la sequenza di avviamento in base alle condizioni. Però vi sono dei limiti oltre il quale anche la gestione elettronica non può andare e in ogni caso sul manuale di ogni macchina, civile o militare che sia, è ben specificato il limite massimo di componente di vento in coda ammesso per un corretto avviamento del motore.

Così recita Flightglobal nel suo articolo già linkato sopra:

https://www.flightglobal.com/news/artic ... ds-439269/

Winds as high as 30kt blew during as the Pratt & Whitney F135 engine began a start sequence, forcing hot air into the Honeywell integrated power package's inlet. As air temperatures rose inside the IPP -- a mini-engine that supplies electric power and starts the engine -- a series of malfunctions occurred. The lower density of the air produced insufficient torque needed to to the engine, which slowed the rotation of the turbine section.

At the same time, fuel continued to supply the engine at an increasing rate, which spurred an engine fire that burst from the exhaust. The tailwind spread the fire across the aircraft and caused significant damage to a portion of aircraft’s aft section. The fire surrounded the engine’s exhaust nozzle, damaging several nozzle segments as well.

The pilot escaped but sustained minor injuries, including burns on his head, neck, face, and ears, the report states. The service has not yet determined the total costs, but estimates aircraft damages will cost above $17 million.

The report also lays blame on a lack of pilot awareness and training for tailwind conditions during an engine start. A pilot checklist included a warning that strong tailwinds during an engine’s start could cause an IPP failure, but the checklist made no warnings about the tailwind limit. The heavily automated F-35A engine start process also led pilots to believe the aircraft handled most of the start procedures and pilots assumed there were no problems if the dials were green, according to the report.

“Preponderance of evidence shows if there had been an expectation of engine startup problems with a tailwind, the [pilot] may have relied less on aircraft automation, and may have identified an abnormal engine start earlier,” writes USAF Colonel Dale Hetke, who conducted the investigation. “This vague awareness led to inadequate training for engine starts with a tailwind. Training also resulted in complacency and an over-reliance on aircraft automation.”


La dinamica dal punto di vista tecnico del problema è spiegata bene nell'articolo. Dal punto di vista del pilota l'eccessiva complacency verso l'automatismo non è mai una cosa positiva, andranno riviste le checklist e il training dei piloti. L'avviamento con forte vento in coda è sempre una situazione delicata per ogni motore, l'automatismo può aiutare entro certi limiti ben precisi stabiliti dal manuale, ma oltre non è il caso di andare. E comunque in condizioni simili è meglio non affidarsi completamente alla macchina e all'automatismo, l'uomo deve mantenere sempre il controllo della situazione per identificare eventuali problematiche in tempo. Io sono sempre convinto che, su ogni macchina, l'automazione deve aiutare l'uomo a svolgere meglio e in sicurezza il proprio compito, supportandolo, non deve sostituirsi ad esso e l'ultima parola e l'ultima decisione deve sempre essere quella dell'uomo.

In response to reports of hypoxia-like symptoms experienced by F-35A pilots at Luke Air Force Base, Arizona, the program office intends to make changes to the onboard oxygen generation system to optimize the flow of oxygen to those flying the jet.
The modification to the onboard oxygen generation system, or OBOGS, involves refining the algorithm associated with oxygen concentration, an F-35 joint program office spokesperson explained in a statement to Defense News.
“There is no indication the delivered oxygen concentration was a contributor to any of the recent events,” said Brandi Schiff.
However, by tweaking the levels of oxygen associated with varying altitudes, the office may be able to help prevent further physiological incidents from happening.

Al MAKS 2017 ..... Sergei Korotkov, Amministratore Delegato della MiG Aircraft Corporation, si è lasciato andare a dichiarazioni alquanto 'spinte' riguardo al MiG-35 .....
MiG Aircraft Corporation CEO Sergei Korotkov expects serial production of the “4+++” fighter to begin in 2019.
Borisov did not say how many aircraft or squadrons of MiG-35s the armament program would support or how many were needed.
Nevertheless, any state order would help anchor the program and make it more attractive to prospective international customers.
Korotkov said during a press briefing at MAKS that despite MiG-35 not having a low-observable airframe planform, the aircraft employs various stealth techniques including radar-deflecting materials and inhibitors as well as electronic countermeasures.
It also has a counter-stealth L-band radar in the leading-edge root extension and could potentially carry the latest X-band Zuke active electronically scanned array radar.
MiG-35 will be powered by two Klimov RD-33MK engines.
Korotkov says the aircraft is competitive against its Western rivals, including the Lockheed Martin F-35.
He was bold enough to say it would even win against the F-35 in aerial combat.
“This is better than the F-35,” he says.

Sulla inderogabile necessità di occultarsi .....
“Stealth” technology hasn’t been rendered obsolete by new radars and detection methods, and has, if anything, become even more of a critical design consideration for future combat aircraft, according to stealth veterans and experts at an AFA Mitchell Institute program at the US Capitol Wednesday.
Presenting a new report, “Survivability in the Digital Age: The Imperative for Stealth,” authors retired Maj. Gen. Mark Barrett (AFA’s former executive vice president) and retired Col. Mace Carpenter (a senior fellow at the Mitchell Institute) said stealth designs continue to be a relatively low-cost factor in new aircraft design, and are crucial not only to the survival of individual aircraft but in making a smaller force possible.

Qualcuno contro corrente, o forse che ha letto tutta la relazione: formiche.net http://formiche.net/blog/2017/08/09/rel ... onti-f-35/

Interessante. E non così negativo come rappresentato dalla nostra stampa generalista :roll:

Lotto 11 ..... forse entro fine Ottobre .....
The F-35 joint program office is aiming to cement a contract agreement with Lockheed Martin for the 11th batch of joint strike fighters by the end of the year.
But the new head of the program office, Vice Adm. Mat Winter, wants to get it done even faster, telling reporters on Sept. 6, “I’m pressurizing the team for 15 October.”

La piroetta del Presidente ..... :hypnodisk:

President Donald Trump hasn’t always been the F-35’s biggest fan, but in a Sept. 15 speech commemorating the Air Force’s 70th birthday, he struck a more reverential tone.
Now, when our enemies hear our F-35 engines, when they’re roaring overhead, their souls will tremble and they will know the day of reckoning has arrived,” he told a crowd of about 800 service members at Joint Base Andrews.
“That is the way it’s been since 1947, when the Air Force was born.”

P&W annuncia il successo di una serie di sperimentazioni effettuate con un motore F135 modificato .....
Tests this year on an F135 core engine paired with an experimental fan module featuring adaptive bypass airflow to improve fuel efficient and cooling capacity “met or exceeded expectations”, says engine manufacturer Pratt & Whitney.
The testing on a full-scale powerplant for the Lockheed Martin F-35 wraps up P&W’s role under a four-year adaptive engine technology development (AETD) programme sponsored by the Air Force Research Laboratory (AFRL).
The testing was intended to understand the maturity of so-called “three-stream” adaptive turbofan technology as AFRL launches a $1 billion programme to develop a full-scale, 45,000lb-thrust-class prototype engine under the Adaptive Engine Transition Programme (AETP) that could be used to re-engine the F-35 and power a future combat aircraft.

Ogni giorno ..... una nuova ..... :mrgreen:
Scores of US-owned Lockheed Martin F-35s would remain in the fleet with a software operating system rated below combat-grade under one of several cost-saving proposals under review by the Joint Programme Office.
Delays during the development stage caused Lockheed to deliver more than 108 aircraft with Block 2B software.
Each fighter requires 150-160 modifications to be raised to the combat-rated Block 3 standard, says Vice Adm Matt Winter, the F-35’s programme executive.
The looming modification bills are threatening to suck resources from a looming production ramp-up with more than 900 aircraft projected for delivery over the next five years, Winter says.
