  Northrop to build 3D-printed scramjet engine for Raytheon hypersonic weapon

  By: Valerie Insinna LE BOURGET, France — Raytheon has partnered with Northrop Grumman on its air-breathing hypersonic weapon, which will be powered by a Northrop-made scramjet made entirely of 3D-printed parts, the company announced Tuesday. Raytheon and Northrop's weapon is one of the competitors in the U.S. Defense Advanced Research Projects Agency's HAWC project, short for Hypersonic Air-Breathing Weapon Concept. The companies' offering — which comprises Northrop's scramjet engine and Raytheon's air vehicle — is ready to make its first flight, said Tom Bussing, vice president of Raytheon's advanced missile system segment. “We have a flight test planned for the near future where we will begin flying this particular class of weapon system,” he said during a briefing at Paris Air Show. While the exact schedule is classified, Bussing noted that the companies have already conducted “significant” ground tests “The combustor, everything that we do now is done by additive manufacturing, so its driving affordability into the hypersonic boost missile's scramjet engine. We are also looking at ways to reduce the weight so we can have more fuel, more payload,” he said. The entirety of Northrop's scramjet is 3D printed using advanced materials, said John Wilcox, the company's vice president of advanced programs and technology. “There gets to be points where you have to weld additive manufactured parts, but right now even the full combustor [is printed],” he said. “We think we're the first to ever 3D print a full combuster for an air-breathing scramjet engine. That's what's going to drive the affordability for air-breathing scramjet missiles.” According to Raytheon, scramjet engines use high vehicle speeds to then compress air moving into its inlets before combusting it. The process allows a vehicle to maintain hypersonic speeds — more than five times the speed of sound — over longer periods of time. The Raytheon-Northrop team is competing against Lockheed Martin for the final HAWC contact. https://www.defensenews.com/digital-show-dailies/paris-air-show/2019/06/18/northrop-to-build-3d-printed-scramjet-engine-for-raytheon-hypersonic-weapon/

  Diversification dans le secteur de la défense : focus sur des PME « duales »

  L'Usine Nouvelle consacre cette semaine un important dossier à l'aéronautique civile et militaire. Eric Trappier, président du GIFAS, y accorde une interview (voir synthèse de presse du 2 juillet). Un article détaillé est par ailleurs dédié aux PME françaises qui trouvent dans les activités défense un amortisseur dans le contexte de la crise du secteur aérien. « Notre dualité est un facteur de robustesse », souligne Bruno Berthet, président de Rafaut. Gauthier Connectique, PME exclusivement positionnée sur l'aéronautique civile il y a dix ans, a opéré avec succès sa diversification. « Entre la décision de se diversifier et les premières commandes, il faut compter environ trois ans. Le fait d'avoir déjà comme clients Dassault Aviation, Safran et Thales nous a beaucoup aidés », explique son président, Luc Sevestre. Le cluster Normandie AeroEspace (NAE), qui regroupe plus d'une centaine de PME de l'aéronautique, a également lancé des actions pour obtenir une habilitation et une accréditation défense, et monte des rencontres avec des représentants du ministère des Armées, de la DGA et des grands industriels de l'armement.

  CAE wins US Navy contract to train UC-12 aircrews

  CAE USA has received a contract to provide classroom and simulator training for the US Navy's UC-12 aircraft's aircrews. As part of the training programme, the company will provide initial and refresher training courses for naval pilots and flight officers. The programme will include training on the King Air 200 Pro Line 21 and non-Pro Line King Air 200 cockpits, in addition to the King Air 350 Pro Line 21 and Fusion cockpits. CAE USA president and general manager Ray Duquette said: “CAE has an unmatched ability to leverage a global network of training centres and training programmes. “The award of this contract is a great example of CAE's Defense and Civil business units working together to deliver a comprehensive training programme for the US Navy. We are particularly pleased that navy C-12 aircrews will be joining the army and airforce in training C-12 pilots at our Dothan Training Center in Alabama.” Alongside Alabama, training will also be delivered at the firm's facilities in Dallas, Texas, and Morristown, New Jersey. The UC-12 is a military version of the Beechcraft King Air multi-mission aircraft. Variants of the Beechcraft C-12 Huron are in service with the US Air Force, Army, Navy and Marine Corps. The navy uses the UC-12 to transport personnel and cargo, as well as for range clearance, medical evacuation, and humanitarian assistance. The department's UC-12B/F/M Huron is based on the King Air B200 aircraft, while its UC-12W Huron is as a modified version of the King Air 350. In May last year, CAE was awarded a contract to deliver instructor support services for providing ground-based training to the US Navy. https://www.naval-technology.com/news/cae-wins-us-navy-contract-to-train-uc-12-aircrews/
