  Rolls-Royce develops world-first electrical technology for next-generation Tempest programme

  Over the last five years Rolls-Royce has been pioneering world-first technology that will contribute to the UK's next-generation Tempest programme. In an aim to be more electric, more intelligent and to harness more power, Rolls-Royce recognised that any future fighter aircraft will have unprecedented levels of electrical power demand and thermal load; all needing to be managed within the context of a stealthy aircraft. Before the launch of the Tempest programme, Rolls-Royce had already started to address the demands of the future. Back in 2014, the company took on the challenge of designing an electrical starter generator that was fully embedded in the core of a gas turbine engine, now known as the Embedded Electrical Starter Generator or E2SG demonstrator programme. Conrad Banks, Chief Engineer for Future Programmes at Rolls-Royce said: "The electrical embedded starter-generator will save space and provide the large amount of electrical power required by future fighters. Existing aircraft engines generate power through a gearbox underneath the engine, which drives a generator. In addition to adding moving parts and complexity, the space required outside the engine for the gearbox and generator makes the airframe larger, which is undesirable in a stealthy platform." Phase two of this programme has now been adopted as part of Rolls-Royce's contribution to the Tempest programme. As part of this journey, the company has been continuously developing its capabilities in the aerospace market, from gas turbine technologies through to integrated power and propulsion systems. The goal being to provide not only the thrust that propels an aircraft through the sky, but also the electrical power required for all the systems on board as well as managing all the resulting thermal loads. Rolls-Royce is adapting to the reality that all future vehicles, whether on land, in the air or at sea will have significantly increased levels of electrification to power sensors, communications systems weapons, actuation systems and accessories, as well as the usual array of avionics. The launch of phase one of the E2SG programme saw significant investment in the development of an integrated electrical facility – a unique test house where gas turbine engines can be physically connected to a DC electrical network. The launch of the second phase of the project in 2017 saw the inclusion of a second electrical generator connected to the other spool of the engine. It also included an energy storage system in the electrical network and the ability to intelligently manage the supply of power between all these systems. The two-spool mounted electrical machines allows, by combination of operation as either a motor or a generator, the production of a series of functional effects on the engine, including the transfer of power electrically between the two spools. As part of the E2SG programme, Rolls-Royce is investigating the feasibility of using dual spool generation to influence the operability, responsiveness and efficiency of the engine. Another key technology under development is the Power Manager intelligent control system, which uses algorithms to make real time intelligent decisions about how to supply the current aircraft electrical demand while optimising other factors including engine efficiency to reduce fuel burn or engine temperature to extend component life. Throughout the Tempest programme, Rolls-Royce will be continuing to mature the electrical technologies demonstrated by the E2SG programme, with a third phase of testing likely to include a novel thermal management system being integrated with the overall system, as well as more electric engine accessories. The company also intends to showcase a full-scale demonstrator of an advanced power and propulsion system. There will be new technologies in all parts of the gas turbine, including twin spool embedded generation to higher power levels, an advanced thermal management system, an energy storage system tailored to the expected duty cycle of the future fighter and an intelligent power management system which will be able to optimise the performance of both the gas turbine and the power and thermal management system.

  Companies are lining up to build a replacement for the MQ-9 Reaper drone

  Valerie Insinna WASHINGTON — As the U.S. Air Force embarks on a new effort to field a replacement for the MQ-9 Reaper drone, multiple defense companies are stepping up with new, long-range, stealthy design concepts for the emerging MQ-Next competition. On Sept. 11, Northrop Grumman and Lockheed Martin released renderings of their respective offerings for the Air Force's MQ-Next program. Northrop made public its swarming SG-2 concept, and Lockheed announced its flying-wing design. General Atomics put out a concept drawing of a next-generation uncrewed aerial system on Sept. 14 to correspond with the first day of the Air Force Association's Air, Space and Cyber Conference. For the past two decades, the Air Force has relied on the MQ-1 Predator and then the MQ-9 Reaper — both made by General Atomics — as its workhorse drones for surveillance and strike missions in the Middle East. But as more commercial drone makers enter the fray, it may become more economical and effective to operate a family of UAVs, with some built for high-end penetrating strike and reconnaissance missions, and others for low-end surveillance from commercial off-the-shelf manufacturers, said Will Roper, the Air Force's top acquisition official. “You might make the case that the Department [of the Air Force] needs both,” he said during a Sept. 15 roundtable with reporters. “But I wanted to give our team time to discuss with industry options that exist on both sides of that divide. We've got a lot of interesting responses, and I'm in discussions right now with the operational side of the Air Force about what they think the requirement is going to be.” The Air Force issued a request for information to industry on June 3, seeking market research on available technologies as well as conceptual designs. Boeing and Kratos each confirmed they responded to the request for information but have not released concept art for their potential offerings. General Atomics, Lockheed and Northrop have begun to shed light on their respective designs. Northrop's flying-wing design bears a close resemblance to the X-47B the company designed for the Navy, including using the same Distributed Autonomy/Responsive Control flight management system, which allows for operators to task multiple drones to fly autonomously according to parameters set by the user. However, the aircraft in the rendering is just one potential concept that Northrop could develop for the MQ-Next family of systems, said Richard Sullivan, the company's vice president of program management. “The customer didn't really give us strict requirements. We know that the [National Defense Strategy] scenario calls out environments with a pretty significant threat scenario. And so, what would we do to mitigate those?” he said. “We looked at those things, and we came up with a family of concepts ... trying to solve the problem across the landscape in terms of the ranges, the threats and the costs.” The General Atomics concept features a stealthy, long-winged, jet-powered air vehicle — a departure from the turboprop-powered MQ-9 Reaper. Dave Alexander, president of General Atomics Aeronautical Systems, told Defense News that the aircraft's survivability and endurance, which is “significantly longer” than the Reaper, will be defining characteristics for the company's offering. Alexander also pointed to internal investments made by the company's aeronautics division and its Electromagnetic Systems Group on advanced propulsion systems, though he declined to say more about potential engine advancements. Keeping costs down will also be an important factor, he said. “Some platforms that get up to super high costs, even though they're unmanned — you can't afford to lose them. So they're not attrition-tolerant, and we want to hang on to that piece of it.” Lockheed Martin's operational analysis has found that an optimal-force mix of drones will require high-end aircraft and low-cost, expendable systems that can operate in swarms, according to Jacob Johnson, the company's unmanned aerial systems program manager. The company's next-generation UAS concept art features a tailless, stealthy, flying-wing design geared toward the high-end fight, although Johnson said Lockheed may put forward less exquisite systems depending on the Air Force's final requirements. “Over the last few years, with a lot of the [drone] shootdowns across the globe, one of the trends that I think is hard to ignore is what used to be considered permissive airspace. [It] is becoming increasingly contested,” he said. “Survivability is really the key to almost any mission, and I think that trend is going to continue into the future.” However, survivability alone will not be enough, Johnson said. The Air Force has made clear that any future air system must plug into the service's Advanced Battle Management System and export data across that system. Lockheed also plans to develop the drone using digital engineering to lower the total cost. https://www.defensenews.com/digital-show-dailies/air-force-association/2020/09/17/defense-companies-are-lining-up-to-build-a-replace

  Lockheed to make wings for F-16 jet in India with partner Tata

  Neha Dasgupta NEW DELHI (Reuters) - Lockheed Martin (LMT.N) will build wings for its F-16 combat plane in India with its local partner, Tata Advanced Systems Limited, an executive at the U.S. company said on Tuesday. Lockheed is bidding for a contract - estimated at more than $15 billion - to supply the Indian air force with 114 combat planes, which must be all manufactured locally under Prime Minister Narendra Modi's flagship Make in India program. However, Vivek Lall, vice president of strategy and business development at Lockheed, said the proposed Indian production of the F-16 wings would not be contingent upon the company winning the order for the planes. “Producing F-16 wings in India will strengthen Lockheed Martin' strategic partnership with Tata and support Make in India,” the company said in a statement. Modi has been pushing for local manufacturing that will provide jobs and also end the military's dependence on imports. Lockheed's announcement came just days ahead of top level talks between the United States and India aimed at expanding defense ties. U.S. Secretary of State Mike Pompeo and Defense Secretary Jim Mattis will meet with Indian Foreign Minister Sushma Swaraj and Defence Minister Nirmala Sitharaman. Boeing (BA.N) has pitched its F/A-18 Super Hornet for the Indian contract as well as Sweden's Saab with its Gripen fighter. France's Dassault (AVMD.PA) Systemes SE's Rafale, the Eurofighter Typhoon and Russian aircraft are also in the fray. Lall said Lockheed had offered to make India its sole F-16 production facility that would supply the Indian military but also other countries. “If India buys the F-16 then it becomes the center of manufacturing for the global market,” he said. Lall said the company planned to begin production of the F-16 wings in the southern Indian city of Hyderabad from 2020. He said these were being produced at a facility in Israel and would not impact any jobs in the United States. The Israeli center will continue to be involved in other production, he said. “All F-16 wings globally are to be built in the Hyderabad facility,” he said. https://www.reuters.com/article/us-india-usa-lockheedmartin/lockheed-to-make-wings-for-f-16-jet-in-india-with-partner-tata-idUSKCN1LK17T
