  Raytheon Wins Air Force F-15, C-130 Cyber Contracts

  By COLIN CLARK PARIS AIR SHOW: Raytheon, which has increasingly focused on its growing cyber and network business, has won contracts to find and fix cyber vulnerabilities in the Air Force's F-15 fighter and C-130 transport fleets. Those are the company's latest deals in what is a business worth at least hundreds of millions of dollars in the last 18 months. It's a big shift, says Dave Wajsgras, president of Raytheon intelligence, information and services. “I think a few years ago there was a lot of talk, and not a lot of action.” But the 2016 National Defense Authorization Act required that all weapons begin to be assessed for cyber vulnerabilities, and the 2019 bill kept pressing ahead. The F-15 and C-130 contracts are among those that have resulted from the NDAA language, Todd Probert, Raytheon's VP for mission support, told me. Because so much of this is classified, Raytheon had to get Air Force permission to talk about the F-15 and the C-130 projects. So what kind of cyber vulnerabilities does an aircraft have? “It's a flying network in and of itself,” Todd said. Aircraft, it turns out, are just as vulnerable as cars, and we've all read stories how hackers have been able to take autos over remotely and stop cars in their tracks. Airplanes have similar points of access, and thus vulnerabilities. Maintainers hook into a plane to find out what's wrong with it. Smart weapons connect to the plane's network. The pilot's helmet mounted display taps into onboard and offboard data. “All these are potential threat vectors we're concerned about,” Todd said. https://breakingdefense.com/2019/06/raytheon-wins-air-force-f-15-c-130-cyber-contracts/

  French vehicle maker Arquus sets its sights on new European battle tank

  By: Christina Mackenzie PARIS – Arquus, formerly Renault Trucks Defense, is keen to get a piece of the emerging Franco-German Main Ground Combat System (MGCS) program. "We think we have things to contribute, notably concerning fuel cells, hybrid drivetrains and robotization,” CEO Emmanuel Levacher told reporters in Paris on Tuesday. While the Franco-German program is generally thought of as a future main battle tank, Arquus is thinking more along the lines of the program's official name: a combat system. “Will tomorrow's tank even be a tank?” asked Arquus' director of innovation, François Deloumeau. He argued that “pushing existing concepts further is not very interesting,” contending that the MGCS was “unlikely to be a super Leclerc tank or a Leopard 3.” Arquus is not being financed to develop ideas for the MGCS, “but we are thinking about it and thinking out of the box,” said Levacher. He mentioned that France and Germany “are not yet aligned in terms of concept, or even of their needs,” which means nothing has been set in stone. “We are talking with the end-users, the DGA and other manufacturers about this,” Levacher said, using shorthand for the French government's defense-acquisition organization. Also on the subject of Germany, Levacher remarked that Arquus was forced to find alternative suppliers of components such as joints, automatic gear boxes or engines designed for civilian vehicles but destined for inclusion in military products for export. That is because Germany export approval procedures “are extremely long” for these types of products, he explained. In addition, the list of countries that Berlin will not give approval for “is getting longer,” with Indonesia and India recently added to Egypt and Saudi Arabia, Levacher said. https://www.defensenews.com/global/europe/2019/02/06/french-vehicle-maker-arquus-sets-its-sights-on-new-european-battle-tank/

  European Hypersonic Cruise Passenger Study Set For New Tests

  By Guy Norris A team of European hypersonic researchers are preparing for wind tunnel tests of a Mach 8 concept that is designed to prove technologies for the development of future ultra-long-range, high-speed commercial vehicles and air-breathing space launch systems. Funded under Europe's Horizon 2020 research and innovation program, Stratofly (Stratospheric Flying Opportunities for High-speed Propulsion Concepts) is targeted at fostering hypersonic capabilities for a 300-seat passenger vehicle cruising above 30 km (19 mi.) to TRL (technology readiness level) 6 by 2035. The project builds on the Lapcat waverider concept developed under earlier programs by the European Space Agency/European Space Research and Technology Center. Using the 310-ft.-long Lapcat II MR2.4 version as a reference vehicle, the 30-month Stratofly effort is focused on classic hypersonic technology challenges such as propulsion integration, hot structures and thermal management. In addition, with environmental concerns at the forefront in Europe, the project also includes sustainability considerations such as fuel-burn efficiency, noise and emissions reductions, as well as operational issues such as life-cycle costs, safety and certification. Coordinated by The Polytechnic University of Turin, Italy, the project team believes that sustainable hypersonic travel is feasible through the use of liquid hydrogen fuel and new trajectories that would enable flights from Europe to Australia in 3 hr. Specific targets include 75-100% CO2 reductions per passenger kilometer and 90% reductions in nitrous oxide (NOx) compared to current long-range transport aircraft. A version of the vehicle could also be adapted into the first stage of a two-stage-to-orbit space launch system, says the group. Other members of the 10-strong consortium include the von Karman Institute for Fluid Dynamics in Belgium, which is focused on propulsion and noise; the Netherlands Aerospace Center, NLR, which is also part of the noise study; and CIRA, the Italian aerospace research center, which is conducting high-speed flow analysis. Propulsion systems and climate impact input is provided by Germany's DLR research organization, while ONERA, the French aerospace research center, is focused on emissions as well as plasma-assisted combustion in the vehicle's combined-cycle propulsion system. Sweden's FOI defense research agency is also part of the plasma combustion study. The French National Center for Scientific Research is also evaluating the vehicle's potential climate impact, particularly in areas such as the effects of water droplets from the exhaust in the upper atmosphere. Studies of the overall business plan, human factors and hypersonic traffic management are being conducted by the Hamburg University of Technology, while the Spain-based Civil Engineering Foundation of Galicia is focused on structural analysis and optimization. Like the original Lapcat design, the Stratofly MR3 waverider configuration is dominated by a large elliptical inlet and an integrated nozzle aft located between two canted tail fins. For takeoff and acceleration up to Mach 4.5, the vehicle is powered by six air turbo ramjets (ATR, also known as air turbo rockets) in two bays of three, each fed by secondary inlets in the primary intake. Above this speed, sliding ramps cover the ATR inlets as the vehicle accelerates and transitions to a dual-mode ramjet/scramjet (DMR) for the next phase of the flight. The DMR is housed in the dorsal section, nested between the ATR ramjets, and is designed to operate in ramjet mode to above Mach 5 and scramjet mode up to Mach 8. The scramjet will incorporate a plasma-assisted combustion system to maintain the stability of the flame front and prevent the potential for flameouts. Tests of the plasma system in a combustor will take place later this year at ONERA, where supersonic combustion testing also took place for Lapcat. The tests will be conducted in November-December at ONERA's ATD5 facility and will focus on inlet conditions at Mach 3.7. Also planned for later this year is a test of the full vehicle in the high-enthalpy wind tunnel at DLR's Gottingen research facility. Testing at DLR will run through September 2020 and is expected to target similar free-stream conditions as those tested on Lapcat II—around Mach 7.8. The work will assess aerothermodynamic characteristics and be used to validate the results of earlier computational fluid dynamics analysis of the MR3 design, which incorporates external and internal differences against the reference vehicle. “We elevated the canard [a retractable feature for lower-speed flight] and redesigned the vertical tails,” says Davide Ferretto, a research assistant on the Stratofly team from The Polytechnic University of Turin. “We also redesigned the leading-edge radius of the inlet for increased efficiency as it feeds both propulsion systems.” As part of the redesign, the enclosed passenger compartment, which was divided into two sections running along each side of the vehicle, has been combined into a single cabin in the lower lobe of the fuselage. https://aviationweek.com/propulsion/european-hypersonic-cruise-passenger-study-set-new-tests
