ADS Show : Thales avance sur la maintenance prédictive

Par Emmanuel Huberdeau

Thales présente au salon ADS Show un outil expérimental pour la maintenance prédictive.

Depuis plusieurs mois, les équipes de Thales développent un outils expérimental de maintenance prédictive destiné à anticiper les pannes et les réparations sur les systèmes électroniques.

Ce système de maintenance prédictive se nourrit de données récoltées par les utilisateurs, les responsable des réparations et les industriels. Un algorithme calcul ensuite les probabilités de panne de chaque équipement. L'outil peut ainsi identifier la probabilité qu'un matériel tombe en panne sur une période donnée et anticiper les pannes. L'utilisateur peut ainsi gérer sa flotte en opération en fonction de ces chiffres mais aussi optimiser sa logistique.

Plus le volume de données est important plus les résultats de l'outil sont précis. C'est pourquoi Thales cherche a obtenir plus d'informations encore via l'intégration de capteurs dit HUMS capables d'enregistrer les paramètres liés à chaque équipements. Thales annonce être le premier industriel a développer des outils de maintenance prédictive pour des systèmes électroniques.

Pour mener ses expérimentations, Thales s'est basé sur des équipements embarqués sur le Rafale. Les essais ont démontré une capacité du système à prévoir huit pannes sur dix.

Les expérimentations ayant porté leurs fruits, Thales prévoit désormais de présenter mi 2019 un système industrialisé. Celui-ci pourra alors servir de base pour développer une interface homme-machine adaptée aux besoins des militaires français. Outre le Rafale, Thales pense pouvoir appliquer son outils de maintenance prédictive dans un premier temps à l'ATL2 et à l'hélicoptère Tigre.

    Elbit UK to make new target-marking kits for British foot soldiers

    By: Andrew Chuter LONDON – Britain's armed forces are investing just over £100 million ($134 million) acquiring equipment to improve sensor-to-shooter capabilities for dismounted troops, the Ministry of Defence announced Jan 21. Under the effort, the UK arm of Israeli-based Elbit Systems has been awarded an £101 million deal to supply the British dismounted joint fires integrators (D-JFI) program. The equipment will give British Army, Royal Marine, special forces and Royal Air Force units improved ability to find, identify and instantly distribute battlefield target information to artillery, aircraft and others. The new kit, based around the latest thermal sight technology, will primarily be used by joint terminal attack controllers and fire-support teams. The contract, which includes support, comes to a close in March 2026, although there is an option to extend it by two years. Elbit Systems UK secured the contract in mid-December, but officials only now announced it. British defense procurement minister Jeremy Quin said the contract “not only delivers the very latest in battlefield technology to our frontline soldiers, but also invests in the British defense industry, sustaining more than 500 jobs across the UK.” In a statement the company said their D-JFI solution will “enable fast and secured transition of target information across the British and allied armed forces, allowing swift and accurate utilization of artillery and close air support.” Several Elbit technologies are being used in the system, including: the TORCH-X battle management application; the HattoriX system for high-precision target marking, the CORAL thermal-imaging system, and the Rattler XR laser designator. This new contract is the latest of a number of deals secured by Elbit Systems UK in recent years, furthering the British Army's digitalization efforts. The company was awarded the £40 million Battlefield Management Application program in 2018 as part of the Morpheus communications modernization program, followed by the Joint Fires Mobile Trainer and the Joint Fires Synthetic Training contract in 2019. https://www.defensenews.com/global/europe/2021/01/21/elbit-uk-to-make-new-target-marking-kits-for-british-foot-soldiers/

  • US spy planes are breaking down ― and lawmakers want answers

    US spy planes are breaking down ― and lawmakers want answers

    By: Joe Gould WASHINGTON ― America's aging C-135 reconnaissance planes keep breaking down, and alarmed lawmakers want the U.S. Air Force to tell them why. Based at Offutt Air Force Base, Nebraska, the 55th Wing's Boeing-made reconnaissance and intelligence-gathering aircraft, all more than 50 years old, are meant to carry out critical missions from operating bases in England, Greece, Japan and Qatar. But an Omaha World-Herald investigative series has found that mechanical problems plague the jets, cutting short 500 of their flights since 2016 and one of every 12 missions since 2015. That's prompted Nebraska lawmakers to write to Air Force Secretary Heather Wilson, urging her to probe and report on the health of the 55th Wing's worn-out fleet. Meanwhile, the Nebraska delegation is trying to fend off an effort within Congress to strip funding to recapitalize the OC-135, which conducts overflights of Russia under the 34-nation Open Skies Treaty. Some lawmakers and Pentagon officials have grown skeptical of the treaty, which allows reciprocal surveillance flights, amid alleged Russian violations, but the administration has requested funds for two new airliners to take over the mission. “It has one of the worst maintenance rates in the United States Air Force,” Rep. Don Bacon, R-Neb., said of the OC-135 on the House floor last week. “It frequently breaks down in Russia, putting us in very hostile, awkward situations with Russians at their bases.” The chair of the Senate Armed Services Committee's Strategic Forces Subcommittee, Deb Fischer, led the letter with Sen. Ben Sasse, a SASC member; Bacon (a retired brigadier general and former 55th Wing commander who sits on the House Armed Services Committee), as well as Reps. Jeff Fortenberry and Adrian Smith. The letter asked Wilson to report on the 55th Wing's safety, security and continued mission effectiveness as well as the Air Force's long-term plans to sustain and recapitalize the wing's capabilities. It referenced the RC-135V/W Rivet Joint, RC-135S Cobra Ball, RC-135U Combat Sent, WC-135 Constant Phoenix, TC-135 Rivet Joint Trainer and the OC-135 Open Skies aircraft. In the current budget season, House and Senate lawmakers have taken divergent approaches to the Trump administration's $222 million request for the two new aircraft. House appropriators and authorizers stripped the funding from their 2019 bills. The authorization bill withholds the funding until Russia adheres to the treaty and agrees to extradite Russians indicted for meddling in U.S. elections in 2016. Fischer helped ensure the Senate-passed 2019 authorization bill did include funding for OC-135 recapitalization, and the bill will have to be reconciled with its House counterpart. Defense Secretary Jim Mattis directed the Air Force to recapitalize the aircraft. He wrote to Fischer in May to acknowledge that unplanned maintenance issues meant the U.S. completed only 64 percent of its scheduled overflights in 2017, while Russia typically completes all of its scheduled overflights. The White House Office of Management and Budget has also issued letters objecting to the absence of OC-135 recapitalization funding in the House bills. https://www.defensenews.com/congress/2018/07/02/us-spy-planes-are-breaking-down-and-lawmakers-want-answers/

  • US Air Force nuclear, space programs take hit in border wall reprogramming

    US Air Force nuclear, space programs take hit in border wall reprogramming

    By: Joe Gould , Aaron Mehta , and Valerie Insinna Correction: A previous version of this story contained an erroneous amount of reprogrammed money. The story has been updated to show the Pentagon reprogrammed $1.5 billion in FY19 funds. WASHINGTON — In the wake of the Pentagon reprogramming $1.5 billion in fiscal 2019 funds to support President Donald Trump's border wall with Mexico, only the U.S. Air Force appears to be losing money appropriated for equipment updates. The funding largely comes from personnel accounts in the Air Force, Navy and Army. But the Air Force is the only service to lose funding for hardware, including nuclear and conventional weapons, surveillance aircraft updates, and space programs. Overall, the Pentagon reprogrammed $818.465 million from FY19 defense appropriations, as well as $681.535 million from FY19 overseas contingency operations accounts, or OCO, to reach that $1.5 billion total. Lawmakers expressed concern that the use of military resources and manpower on the southern border will damage military readiness. However, acting Defense Secretary Patrick Shanahan said last week that ongoing deployments to support the Defense Department aren't doing so. “We've seen no degradation to readiness,” he told Senate appropriators May 8 at a defense budget hearing. “In fact, in some cases, it's enhanced our readiness because the troops get to perform certain functions.” Congressional Democrats and some Republicans have objected to the administration's use of this mechanism for funding the president's border wall, arguing it bypasses Congress' constitutional power of the purse. For the second time in recent weeks, the Pentagon ignored decades of precedent and carried out the transfer of funds without first consulting with the Senate Appropriations Committee. Sen. Patrick Leahy, the Senate Appropriations Committee's top Democrat, led a letter to Shanahan on May 10 to object to the latest instance, saying it harms hurricane cleanup at Tyndall Air Force Base, Florida. “We are dismayed that the Department has chosen to prioritize a political campaign promise over the disaster relief needs of our service members, given the finite reprogramming authority available," the lawmakers wrote. They noted that Shanahan's decision to notify Congress of the reprogramming came a day after he testified before the subpanel that oversees defense spending, and they wrote that they welcomed his views on “how you intend to repair the damaged relationship between the defense oversight committees and the [Defense] Department.” The letter was also signed by the Senate Armed Services Committee's top Democrat, Sen. Jack Reed, as well as Democratic Sens. Dick Durbin, Brian Schatz, Tom Udall , Patty Murray, Chris Murphy, Tammy Baldwin, Dianne Feinstein and Jon Tester. The reprogramming could be a topic at Shanahan's future confirmation hearing for the full job of defense secretary. A date for that hearing has not been set. Why the Air Force? About half of the non-OCO $818 million sum the Defense Department wants to redirect to the border comes from Air Force accounts, with space and missile programs taking the biggest hit. In total, the Pentagon expects the service to shear $402 million off its FY19 budget. About $210 million would be cut from Air Force space programs, specifically the Evolved Expandable Launch Vehicle program, which funds the use of rockets that send satellites and other capabilities into space. According to the reprogramming document, one rocket launch has been canceled due to the “Space Test Program (STP)-4 satellite provider termination of the Robotic Servicing of Geosynchronous Satellites (RSGS) spacecraft,” which is no longer necessary under the National Security Strategy. The Air Force's program for modernizing its E-3 Sentry early warning aircraft — more commonly called AWACS — also could lose funding that it no longer needs in FY19. The program, "Diminishing Manufacturing Sources Replacement of Avionics for Global Operations and Navigation,” or DRAGON, updates the E-3's avionics and brings it into compliance with future air traffic control requirements. But it is moving too slowly to use all of the funds it was appropriated in FY19, so the administration aims to have $57 million diverted for border protection. DRAGON has been delayed for two reasons, according to the reprogramming request. First, “aircraft have been available for programmed depot maintenance” at a slower-than-planned rate, dragging out the modification schedule. Additionally, DRAGON integration can only occur after AWACS are upgraded to the Block 40/45 configuration, and not all aircraft have gone through that process. The Air Force sees AWACS as a key part of its initial version of the Advanced Battle Management System, a family of systems that will provide ground surveillance across the different military services. Instead of retiring seven E-3s in FY18, Gen. Mike Holmes, head of Air Combat Command, said those planes could be upgraded with new sensors and communications gear. However, DRAGON isn't the only modernization effort for the Sentry that is moving slower than expected. In November, Bloomberg reported that the service terminated a contract with Boeing to upgrade the AWAC's characteristic disc-shaped radar due to repeated delays. Other Air Force programs that will take a hit include a planned upgrade to the Minuteman III intercontinental ballistic missile and the air-launched cruise missile programs. A number of top defense officials previously said nuclear modernization is the top priority for the Pentagon, including Ellen Lord, the department's acquisition head, who on May 1 told Congress: “We have weapons that are decades over what was supposed to be their useful life. And we are out of time. We need to continue on the path we're on, or we are going to fall behind and not have the nuclear deterrence that we enjoy today.” The document reprograms $24.3 million, of the $124.5 million appropriated in FY19, from the Minuteman III Launch Control Block Upgrade program; the document claims funds are available due to a “slip in the production schedule for FY 2020.” Meanwhile, $29.6 million — more than half of the $47.6 million appropriated for the air-launched cruise missile programs in FY19 — will be reprogrammed. The explanation for that change: “Funds are available due to contract savings from reduced guided missile flight controller modification requirements; and due to lack of executable requirements for Support Equipment and Low Cost Mods in FY 2019.” The reprogramming of funds for the Hellfire missile is also notable, as the Pentagon has identified a lack of munitions stockpiles as a major issue to address in its budget request. As an example, the FY20 budget called for the maximum rate of production possible on Hellfire: $730.8 million for 9,000 of the weapons. The document states that funds are “available due to contract savings from all variants that provide precision kill capabilities. Savings are attributed to negotiated lower unit costs per missile system.” https://www.defensenews.com/smr/federal-budget/2019/05/13/us-air-force-nuclear-space-programs-take-hit-in-border-wall-reprogramming/
