Why the Pentagon’s use of 3D printing is ‘not quite there yet’

The needs are perhaps most clear for the Navy, and yet even for that service, the technology — and the path to using it more widely — is still maturing.

    RAF, l’Eurofighter en successeur du Tornado !

    La Royal Air Force prépare activement la mise à jour de sa flotte d'avions de combat Eurofighter « Typhoon II » en vue du remplacement du Panavia Tornado GR4. En effet, les dernières unités de « Tornado » devraient être retirées au début de l'année 2019. Project Centurion : Le programme « Poject Centurion » doit permettre à l'avion européen d'égaler la capacité d'attaque au sol du « Tornado » et de la dépasser à terme. Pour remplacer complètement le « Tornado » au sein de la RAF, les « Typhoon II » devront porter les mêmes armes, avec la phase 2 et phase 3 d'amélioration (P2EA et P3EA) qui, à leur tour, constituent la première phase et la deuxième phase du programme « Centurion ». Ils ont été précédés d'un Phase Zero (P1EB ou Phase 1 Enhancement Further Work). La phase zéro a été livrée en décembre 2017, officiellement entrée en service en janvier 2018 et est désormais opérationnelle dans le cadre de l'opération «Shader». La configuration du projet « Centurion » est destinée à combiner la bombe guidée de précision Raytheon Paveway IV déjà livrée avec les missiles « Storm Shadow », « Meteor » et « Brimstone » sur le Typhoon FGR4. L'avion devra prochainement venir remplacer le Panavia Tornado GR4 au début de l'année 2019. Les avions de première phase qui sont livrés ont été équipés de la mise à niveau « Typhoon » Phase 2 Enhancement (P2E) qui comprend le « Meteor » et le « Storm Shadow ». La phase 2 du projet Centurion couvre la mise à niveau de la phase 3 du Typhoon Enhancement (P3E) avec l'arrivée du « Brimstone ». Les essais sont maintenant en cours, la configuration finale du projet « Centurion » devrait être prête pour la fin de 2018. Les appareils concernés font partie de la Tranche 1 (51), la Tranche 2 (67) et environ 10 appareils de la Tranche 3. A noter que 24 Eurofighter de la tranche 1 qui doivent être retenus serviront uniquement à la défense aérienne et ne recevront pas la mise à niveau du projet Centurion. Environ 65 à 75 sorties devraient être enregistrées avant qu'une phase d'évaluation opérationnelle ne commence à au sein de la base aérienne de la RAF de Coningsby dans le Lincolnshire le 10 août prochain. Cela comprendra également des essais de tir complets avec l'arme de précision. D'autres améliorations incluent des mises à jour de l'interface homme / machine du "Typhoon", avec notamment le système de visée monté sur un casque Striker fourni par BAE. Le Storm Shadow : Le SCALP (acronyme de « Système de croisière conventionnel autonome à longue portée »), anciennement « Arme de précision tirée à grande distance », est un missile développé fin 1994 MBDA. La version britannique est baptisée «Storm Shadow». Cette arme est conçue pour frapper l'ennemi dans son territoire profond, quelle que soit la défense aérienne gr'ce à sa furtivité qui le rend indétectable, y compris par les avions radars. Le MBDA Brimstone : Le missile Brimstone air-sol britannique fabriqué par MBDA sur commande de la Royal Air Force. Il est équipé d'un guidage laser et d'un radar millimétrique, ceci afin de le rendre plus efficace contre des cibles mobiles. Le missile Meteor : Le Meteor est prioritairement réservé aux missions d'interception à grande distance, au-delà de la portée optique (BVR) de tout type d'aéronefs. Son utilisation est privilégiée pour les cibles de haute valeur telles que l'attaque à plus de 100 km d'avions radar ou de ravitailleurs. Ce missile va permettre d'assurer une efficacité de destruction à des distances aujourd'hui encore importantes, de l'ordre de 50 Nm (entre la cible et l'avion tireur au moment de l'impact). A cette fin, le système d'arme comporte : Un radar de bord qui fournit des informations précises sur la cible avant le départ du missile, et une liaison de données de type Link16 assurant les mêmes fonctions en retransmettant vers l'avion tireur les informations d'un capteur porté par un autre aéronef. Des systèmes d'identification des cibles à des distances compatibles avec la portée du missile. Une manœuvrabilité suffisante du missile dans toutes les phases de vol, pour toutes les distances de tir, qui doit lui assurer une grande probabilité de destruction des cibles. La propulsion de ce missile est également un défi technologique du fait du concept retenu : celui d'un statoréacteur. Ce statoréacteur à propergol solide et à poussée régulée (Throttleable Ducted Rocket ou TDR) dans sa phase de croisière comporte un accélérateur à poudre intégré dans la chambre de combustion, ce qui permet de donner une impulsion initiale suffisante pour atteindre une vitesse compatible avec le fonctionnement du statoréacteur. http://psk.blog.24heures.ch/archive/2018/09/30/raf-l-eurofighter-en-successeur-du-tornado-866306.html

    European Nations Are Teaming Up to Make a 6th-Gen Fighter. Can the US Keep Up?

    By Oriana Pawlyk SALON DU BOURGET, PARIS -- France made a splash at this year's Paris Air Show, unveiling a sixth-generation fighter design, the Future Combat Air System. The Dassault-made aircraft, which is set to be made in collaboration with Airbus and acquired by Spain and Germany as well as France, represents a renaissance in European aviation, French President Emmanuel Macron said. The unveiling comes just a year after BAE Systems debuted a concept model for a future British 6th-generation fighter, the Tempest. Is Europe now on a trajectory to beat the U.S. to acquisition of 6th-generation fighter technology? "I would have to say no," Acting Air Force Secretary Matt Donovan said here Monday during the airshow. Donovan and Dr. Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics, both noted last year upon the unveiling of the Tempest fighter in the U.K. that, while competition is "a good thing," any fighter NATO partners and allies aim to produce in the future should be complementary to U.S. capabilities. They stressed the same message after France unveiled the Future Combat Air System. "We're putting a lot of focus into our next-generation programs right now to make sure we're going to lead the way to sixth-generation systems," Roper said. Roper and Donovan said they have yet to have a full briefing about what Europe's latest fighters, including the United Kingdom's Tempest jet, look like beneath the surface design. "We would just like to cooperate and collaborate ... as well as to share technology, [which is] absolutely important for future interoperability if we're going to go to war as coalitions, which we always do, so that's really important," Donovan said. Roper said it's not just about what a fighter can do, but also how it's made. Discussions are ongoing within the Air Force about the need for a sixth-gen fighter, he said. Leveraging the use of "digital engineering," which sometimes allows the service to bypass the regular manufacturing process for parts, will give developers the ability to design and change blueprints with more flexibility, Roper said. The Air Force is currently using digital engineering for A-10 Warthogs, as well as the Ground Based Strategic Deterrent program, which is set to replace the Minuteman III intercontinental ballistic missile system. "We [believe the] production technology may be the most game-changing component if it allows us to move into a different paradigm of doing rapid design spirals and updates," Roper told reporters here, adding that technology growth paired with digital engineering will allow for faster production of future aircraft. Roper said the Defense Department is used to outdated acquisition practices, out of step with what the pilot may need to outpace adversaries. "In addition to looking at a lot of classified capabilities we want to give future warfighters, we also want to give manufacturers a different way of making that cutting-edge technology. Expect [that] for what we bring to the table for sixth-gen," he said. "We're here to also ... connect with the future," Roper added. "Aviation is a booming business right now in Europe, so we're interested in seeing who the new movers and shakers are, engaging with some of the companies here in France, but also showing that some of the systems that we bring to bear from the U.S. are the best in the world, and we see a future where we maintain that edge far past our successors." https://www.military.com/daily-news/2019/06/18/european-nations-are-teaming-make-6th-gen-fighter-can-us-keep.html
