  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/

  The Hornet Jumps

  Marc Cook December 21, 2020 Boeing has demonstrated yet another capability of the ever-young F/A-18 Super Hornet by proving it can “operate from a ‘ski jump' ramp, demonstrating the aircraft's suitability for India's aircraft carriers,” according to the company. India uses something called STOBAR, for Short Takeoff But Arrested Recovery, that uses a ramp-assisted takeoff relying only on the aircraft's thrust and benefiting from the ship's forward motion, combined with more conventional arresting methods for landing. It's said that STOBAR carriers are cheaper to build than those with powered catapults. “The first successful and safe launch of the F/A-18 Super Hornet from a ski jump begins the validation process to operate effectively from Indian Navy aircraft carriers,” said Ankur Kanaglekar, India Fighter Sales lead for Boeing. “The F/A-18 Block III Super Hornet will not only provide superior war fighting capability to the Indian Navy but also create opportunities for cooperation in naval aviation between the United States and India.” “This milestone further positions the Block III Super Hornet as a versatile next-generation frontline fighter for decades to come,” said Thom Breckenridge, vice president of International Sales for Strike, Surveillance and Mobility with Boeing Defense, Space & Security. “With its proven capabilities, affordable acquisition price, known low documented life-cycle costs and guaranteed delivery schedule, the Block III Super Hornet is ideally suited to meet fighter aircraft requirements of customers in India, North America and Europe.” The demonstration is part of Boeing's sales pitch to the Indian navy, which has not chosen which fighter to purchase. It will be looking to add to its fleet of MiG-29K fighters and is considering both the F/A-18 and the Dassault Rafale. Also part of the pitch: “Boeing has strengthened its supply chain with 225 partners in India and a joint venture to manufacture fuselages for Apache helicopters. Annual sourcing from India stands at $1 billion. Boeing currently employs 3,000 people in India, and more than 7,000 people work with its supply chain partners.” https://www.avweb.com/aviation-news/the-hornet-jumps/
