Dassault Aviation achève le déploiement de 3DExperience

Par Léo Barnier

Le groupe Dassault Aviation vient de passer une étape importante dans son processus de transformation numérique, en coopération avec Dassault Systèmes. L'avionneur français vient d'achever au mois de juillet le déploiement de la plateforme 3DExperience, développée par sa société « cousine », pour l'ensemble de ses programmes civils et militaires. C'est notamment le cas pour le futur Falcon qui doit être lancé prochainement.

Toutes les équipes de Dassault Aviation vont ainsi évouler sous un même environnement numérique. Il s'agit ainsi de créer une continuité qui s'appliquera depuis la conception des nouveaux programmes jusqu'aux services de soutien après-vente. Chacun pourra ainsi travailler sur une maquette numérique unique, qui intègre les demandes spécifiques de chacun, avec des outils compatibles entre eux.

Cela doit permettre par exemple au bureau d'études de prendre plus largement en compte les contraintes de l'ensemble du cycle de vie d'un produit ou d'un programme (production opérations, maintenance, rétrofit...) dès les premières esquisses, afin d'optimiser celui-ci dans la durée. A la clef, des gains de temps et de coûts pour le cycle de développement d'un avion - le nouveau Falcon notamment - comme pour la suite de sa vie opérationnelle.

Comme l'explique David Ziegler, vice-président Industrie aéronautique et défense de Dassault Systèmes : « La plateforme 3DExperience représente une approche holistique de l'innovation. Elle permet à Dassault Aviation d'accéder à des technologies et à des capacités intégrées et de relier tous les points, du concept aux opérations... »

Les différents services du constructeur disposeront d'outils entièrement intégrés dans cette plateforme unique, mais adaptés à leurs besoins spécifiques. Dassault Systèmes mentionne ainsi six solutions industrielles choisies par Dassault Aviation : Winning Concept, Program Excellence, Co-Design to Target, Ready for Rate, Build to Operate et Keep Them Operating.

Dassault Aviation entend aussi déployer cette continuité vers sa chaîne d'approvisionnement avec trente sociétés identifiées, comme l'explique Jean Sass, directeur général Systèmes d'information de Dassault Aviation : « Tous nos partenaires industriels travailleront en collaboration avec leurs clients sur une seule et même plateforme numérique. À terme, nous serons en mesure de proposer à nos clients de nouvelles expériences de vol à la pointe de l'innovation. »

Cette démarche de transformation numérique à l'aide de 3DExpérience a été entamée l'an dernier, en mai exactement. Dassault Aviation et Dassault Systèmes avaient alors signé un contrat pluriannuel pour remplacer l'ensemble des solutions de gestion du cycle de vie des produits (PLM) de l'avionneur.

  • Austal Expanding Yard In Alabama as It Eyes New Unmanned, Amphibious Shipbuilding Programs

    Austal Expanding Yard In Alabama as It Eyes New Unmanned, Amphibious Shipbuilding Programs

    Megan Eckstein Austal USA is expanding the capacity and capability of its Alabama shipyard, doubling down on investing in its future in a way reminiscent of 2009, just before it won the block buy of Littoral Combat Ships that secured the yard a spot in the U.S. shipbuilding industrial base. The Mobile yard this month closed on the purchase of a ship repair facility formerly owned by World Marine of Alabama, an indirect subsidiary of Modern American Recycling and Repair Services of Alabama. It includes a 20,000-ton Panamax-class floating dry dock, 100,000 square feet of covered repair facilities and 15 acres of waterfront property along the Mobile River and Gulf of Mexico, according to a company statement. Shipyard President Craig Perciavalle told USNI News this week that the expansion fits in with its desires to continue building aluminum ships and to expand into building steel ships – manned or unmanned – as well as a desire to take on more repair work for the Navy and other customers. “We feel we're putting ourselves, and we've put ourselves, in a very good place to continue to provide very capable but lower-cost ships to the Navy,” he said of the yard that today builds Independence-variant LCSs and Expeditionary Fast Transit (EPF) ships. “I have had some discussions with [Defense Secretary Mark] Esper, we are encouraged by the plan for, the need and the requirement for 355 ships or more maybe. And I think there's plenty of opportunities for us to help the Navy grow the fleet, and we're putting ourselves in a very good position to help the Navy do that long-term.” The yard expansion gives Austal ownership of a dry dock it was leasing to launch its ships into the Mobile River, eliminating any schedule problems the yard had to worry about in the past if its desired timeline didn't match up with the dry dock's availability to be leased. “We'll just have complete control over it, and then we can have the priority for the dry dock be supporting our business, first and foremost,” Perciavalle said. He added that the rest of the facility, on the other side of the river and just south of Austal's property, could be refurbished or upgraded in the future to support ship construction or repair activities as needed, giving Austal some flexibility as its future workload becomes clearer. Many in the Navy and industry have expressed concern about Austal's future, with the company's LCS construction coming to an end in a couple years – four ships are in construction at Austal and four more are in pre-construction – and its future with the EPF program still uncertain, as the Navy and Congress haven't made any firm decisions about continuing the hot production line to build an ambulance ship variant of the hull. Austal competed to build the Navy's FFG(X) frigate program and lost, leaving many wondering what would happen to the yard, its workforce and its suppliers. Perciavalle said he's not worried about the yard's future. “It's no secret that we're focused on the unmanned side of the business, we think there's obviously plenty of opportunities there and we're going to, hopefully – our plan is to be a major player in that side of the market,” he said. Austal is one of six companies selected to conduct industry studies on the Navy's Large Unmanned Surface Vessel, and Austal also participated in the LUSV precursor by converting a vessel to an unmanned ship through the Pentagon's Overlord USV prototype effort. “We are encouraged by discussions around additional EPFs going forward. EPF-15 has been in and out of the budget, and the latest discussions show that there might be some opportunities for that to get back in. I think it's no secret that we've been looking at expeditionary medical ships that have been discussed, and we feel we're in a pretty good place to support those needs to the Navy,” he continued, with the Congress this current fiscal year appropriating money to give EPF-14 a greater medical capability. “And then from a steel shipbuilding perspective, there's certainly opportunities from that medium-sized type vessel: [Light Amphibious Warship] is one that we've been participating in. We have participated in some of the industry studies on [the Coast Guard's Offshore Patrol Cutter]. And without getting into much more detail beyond that, there's opportunities that exist across the board that we're going to continue to look at and to pursue. “ Asked by USNI News if the range of work – from unmanned vessels to amphibious ships to Military Sealift Command support ships to Coast Guard cutters – spurred Austal to take a leap of faith and expand the shipyard now, Perciavalle said, “this is something that Austal's done in the past, so been there done that. We leaned into the facility that we have today, committing much of those funds before (LCS) block buys were even awarded back in the ‘09 and 2010 time period. We have seen where the Navy looks like they're going, and we're leaning into those requirements going forward. There seems to be opportunities both on the steel ship side of things as well as aluminum, and we're going to leverage our strength and what we've been able to do from an aluminum perspective, and take those same strengths and transition adding the steel capabilities.” “So yeah, it's pretty interesting times, it's pretty exciting. We've proven in the past that we're pretty darn good at building lots of ships in a relatively short period of time. I think we've delivered 23 surface ships to the Navy over the last just over seven and a half years,” he continued. “We believe there's value in that for the Navy and trying to expand to 355 in a reasonable timeframe, and I think leveraging the industrial base that we have here in Mobile is going to be important to the Navy's ability to do that.” In addition to the physical expansion of the yard through the recent acquisition, Austal and the Defense Department are spending $100 million to bring a steel shipbuilding capability to the yard that today only builds aluminum ships. DoD offered its half under the Defense Production Act Title III (DPA) Agreement “to maintain, protect, and expand critical domestic shipbuilding and maintenance capacity,” according to a DoD announcement. The money, appropriated as part of the coronavirus pandemic relief bill passed by Congress in the spring, will not only help the Navy industrial base but will “accelerat[e] pandemic recovery efforts in the Gulf Coast region” by supporting the economy. Perciavalle said the yard decided to match the contract with its own $50 million investment in the steel shipbuilding capability. Perciavalle said another growth area for Austal is likely to be ship repair, though the Navy has not made its intentions public yet. Austal is somewhat challenged in that every single LCS it has built is stationed in San Diego, which is a Panama Canal transit away. The San Diego ship repair industrial base is under pressure to keep up with the Navy's growing surface ship maintenance and modernization needs, and although Austal has a support office in San Diego and can contribute to pier-side work at the naval base, it cannot take on maintenance availabilities on its own yet. “The Navy's aware of our interest in expanding our service business, and I think given the fact that they're looking for increased capacity in that regard, I think it's welcome,” he said. “And then we'll just see how things go both here in Mobile, obviously continuing to support efforts on the West Coast, and then in Singapore,” where Austal has an office to support forward-deployed LCSs operating in the Indo-Pacific region. USNI News previously reported that Austal was trying to conduct some LCS work in Mobile after sea trials and ship delivery, but before the ships headed through the canal and onto San Diego. Perciavalle said that has continued, but that the ships are coming out of the yard with very little work waiting to be done during the post-shakedown availability. He said he hopes the Navy and the yard can find a way to bring more repair work to Mobile, to ease the strain in San Diego and to fully leverage the dry dock the yard now owns. Additionally, while his focus is maintaining the ships that Austal built, Perciavalle said “the sky is the limit” in terms of the yard taking on repair and modernization work for Military Sealift Command ships, Coast Guard ships or commercial vessels. “The facility has been in the past supporting various markets and will continue to do that going forward,” he said of the newly purchased property that also includes deep-water berthing space for in-water repairs in addition to the dry dock for out-of-water repairs. He noted that the team operating out of Singapore had contributed to the success of overlapping USS Montgomery (LCS-8) and USS Gabrielle Giffords (LCS-10) deployments there and that Austal planned to maintain or grow its presence in Singapore. “Our game plan is there will be at least two ships there going forward, we are fully prepared to support having two ships in Singapore or more,” as well as sending flyaway teams or setting up offices anywhere else the Navy chooses to hub the LCSs or EPFs around the globe. https://news.usni.org/2020/09/15/austal-expanding-yard-in-alabama-as-it-eyes-new-unmanned-amphibious-shipbuilding-programs

    Huge Deficit = Defense Budget Cuts? Maybe Not

    The congressional calendar and strategic inertia may come together to keep the defense budget relatively high. The calendar helps because the fiscal 2021 defense budget will likely be passed while Congress is in a free-spending mood. By MARK CANCIAN The current Washington consensus sees deep defense budget cuts in the face of soaring deficits driven by the emergency legislation to stabilize the American economy as it reels from the effects of the COVID-19 pandemic. It may be wrong. The congressional calendar and strategic inertia may come together to keep the defense budget relatively high. The calendar helps because the fiscal 2021 defense budget will likely be passed while Congress is in a free-spending mood. The next administration — Republican or Democratic — will develop budgets beyond that, but the constraints of long-standing strategy will prevent major changes to force structure and acquisition that would drive deep budget cuts. The Challenge The conventional narrative holds that the defense budget will be squeezed as the debt level rises, and the public focuses inward on rebuilding the country's health and economic position. These are reasonable concerns. The deficit in fiscal 2020, initially projected to be about one trillion dollars ― itself getting into record territory without emergency spending― is now projected to be $3.7 trillion, and Congress is not finished spending. Debt held by the public will rise to 101 percent of GDP, a level not seen since World War II. Even if the world is willing to take US debt, rising interest payments will squeeze the rest of the budget. Simultaneously, the electorate is likely to focus inward. The pandemic is already the leading popular concern, not surprisingly. The economic devastation caused by restrictions on normal commercial activities has produced the greatest downturn since the Great Depression. It would be reasonable to put these factors together and project a substantially reduced defense budget. However, the congressional calendar and the inertia of a long-held strategy will likely mitigate any downturn. The Calendar The calendar will help because Congress is likely to pass the 2021 appropriation this fall, when the government will still be operating under emergency conditions. Congress has already passed four bills for pandemic response and economic stimulus and is developing another in the multi-trillion range. There are a few voices for fiscal constraint, but they are overwhelmed by a sentiment to “do more.” Indeed, some lawmakers and commentators are proposing increases to the defense budget to stimulate the economy, enhance deterrence of China, or protect the defense industrial base. Adam Smith, chairman of the House Armed Services Committee, has indicated his reluctance to do more than protect the industrial base, but a future stimulus bill could include such enhancements as part of a bipartisan deal. Finally, last year's bipartisan budget agreement set levels for defense and domestic spending in fiscal 2021. Undoing that agreement would be a major lift, requiring a bipartisan consensus that does not seem to be occurring. Even if the Democratic left wanted to make such cuts, defense hawks in the House and Senate could block them. Thus, in the near-term proposals for enhancements seem to be offsetting thoughts about cuts. As both the House and Senate consider their authorization acts, they seem to be aiming at roughly the level of the president's proposal and the bipartisan budget agreement. Strategic Inertia The United States has had some variation of the same national security strategy since the end of the Second World War (or perhaps more accurately, since the Korean War and publication of NSC 68, which enshrined a long term competition with the Soviet Union). That strategy involves global engagement, forward-deployed forces, alliances to offset global competitors, and commitment to maintaining an international system of free trade, human rights and secure borders. Scholars can argue about the details and how well the United States has implemented such a strategy, but the major elements have been constant. President Trump has chafed at many of these elements but has generally gone along, however reluctantly. One would expect such reluctant continuity in a second Trump administration, should that occur One would also expect strategic continuity in a Biden administration. Biden was, after all, vice president during the Obama administration, which, after the shocks of 2014, laid out a strategy of confronting five threats: Russia, China, North Korea, Iran, and terrorism. One would expect Biden to implement something like that strategy if he were in office. That does not mean that a Biden administration would do everything a Trump administration would do. The left-wing of the Democratic party would push some level of cuts, perhaps 5 percent, and take aim particularly at nuclear modernization, foreign arms sales, and Middle East conflicts. But this longstanding strategy of global engagement will put a floor on defense cuts. Remaining engaged with NATO, supporting our Asian allies like Japan and South Korea, and maintaining some presence in the Middle East, even if scaled back, takes a lot of forces. These need to be at a relatively high level of readiness to deploy globally and be credible. The all-volunteer force needs to maintain compensation and benefits at a sufficient level to compete for labor in a market economy. Competing with China and Russia requires investment in a wide variety of high technology―and costly―new systems, as well as the R&D foundation to support these innovations. Other strategies are certainly possible. Members of the Democratic left and Republican right, as well as some elements of the academic and think tank community, have proposed strategies of “restraint”, whereby the United States would significantly scale back overseas engagements. Such strategic change would produce a substantial cut in the defense budget. However, neither major candidate has supported such a change, and the national security policy community (aka “the blob”) is adamantly opposed. Despite this relatively optimistic assessment, the future is still cloudy. The president's budget proposal forecasts a level budget in constant dollars. That meant that the defense buildup was over, even if Republicans continued in office. Such budgets do not come close to the 3 to 5 percent real growth that defense officials had talked about to implement the National Defense strategy and would entail choices between readiness, force structure and modernization. A Democratic administration, with a notional 5 percent cut in the defense budget, would not constitute the deep cut that a Sanders or Warren administration might have entailed, but the $35 billion that a 5 percent cut would entail is still a lot of money. Forces would get smaller, likely wiping out all the recent force expansion, and new programs would be delayed. Bottom line: Defense may not be heading into a budget hurricane, but it is not heading into sunlight either. It faces the friction that occurs when expensive plans collide with constrained resources.
