  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.

  Trump signs defense spending plan, with one more swipe at Democrats

  By: Leo Shane III WASHINGTON — President Donald Trump finalized an $854 billion spending bill on Friday that fully funds the military for fiscal 2019 and prevents a government shutdown next week, accomplishments that congressional leaders have called important and laudable. But Trump's signature came with one final attack on Democrats over the spending measure, lamenting lawmakers' decision not to include extra money in the appropriations package for his planned wall along the southern U.S. border. “Unfortunately, the radical Democrats refuse to support border security and want drugs and crime to pour into our country,” he said in a statement after signing the bill. The comments came just a week after Trump took to social media to blast “this ridiculous Spending Bill,” raising fears of a presidential veto on Capitol Hill. Instead, Trump largely praised the measure on Friday, calling it “important legislation to rebuild our military” and promote other domestic priorities. The appropriations measure includes $674 billion in defense funding for fiscal 2019, and marks the first time in a decade Congress has finalized the spending measure before the start of the new fiscal year. The measure funds a 2.6 percent pay raise for troops starting next January and a boost in military end strength of 16,400 spread across the active-duty and reserve forces. Trump, in his statement, praised the measure for including “93 new F-35 Lightning Joint Strike Fighters, 142 Apache and Black Hawk helicopters, and 13 Navy battle force ships — made right here in the USA.” In a statement after the signing, House Armed Services Committee Chairman Mac Thornberry, R-Texas, praised the president for pushing for the funding increases in his budget request and past public statements. “By funding our military in full and on time, we can begin to restore its strength, agility, and effectiveness,” he said. “As I have said before, the task before us now is to make full, on time funding of our military the rule in Washington, and not the exception.” The spending bill also includes full-year funding for the departments of Health and Human Services, Education and Labor, as well as bridge funding for a handful of other government agencies to keep them operational through Dec. 7. Last week, Trump signed into law a separate package that included full-year funding for the Department of Veterans Affairs and for military construction projects. https://www.militarytimes.com/news/your-military/2018/09/28/trump-signs-spending-plan-avoiding-shutdown
