    New Images Of The Tempest Sixth-Generation Aircraft Revealed During UK Industry Engagement Event

    Development for the new Tempest sixth-generation fighter is moving on with some revolutionary concepts. Team Tempest and the Royal Air Force recently held a virtual event to provide an update about the development opportunities of the new sixth generation aircraft to industry and government representatives from Northern Ireland, the first of a series of events to engage with industries across the UK. Within the press release there is also some new renderings of the aircraft which, we have to note, is not in its final shape as it's being designed “from the inside out” and the airframe's exterior design may change to reflect changes in the internal systems. According to the press release, “Delegates heard from Air Chief Marshal Sir Michael Wigston and other RAF senior leaders who highlighted how Team Tempest is taking a revolutionary approach to partnership, engaging with a wide range of leading companies, SMEs and academia to bring leading innovators into the endeavour and ensure the UK remains at the leading edge of Combat Air systems development. The RAF Capability leadership team highlighted updates in emerging strategy and identified examples of innovation and future opportunities. Key members from the Team Tempest industry partner community also provided attendees with updates on the programme and explained how Tempest is working in radical ways to develop world-leading capability, with a focus on affordability and efficiency.” Team Tempest is currently made of the core industry partners BAE Systems, Rolls Royce, Leonardo UK and MBDA UK, which were joined last year by Leonardo Italy, Elettronica, Avio Aero, MBDA Italy, Saab and GKN Aerospace Sweden and, more recently, by Thales UK, Bombardier Belfast, Collins Aerospace, GE Aviation UK, GKN Aerospace, Martin Baker and QinetiQ. A widespread industry participation is considered essential for the programme to bring the best expertise to work on the more than 60 technology demonstrations which are currently in progress. According to a statement shared by the UK Ministry of Defence and the core industry partners, “Tempest is one of the UK's most ambitious technological endeavours and designed to deliver a highly advanced, adaptable combat air system to come into service from the mid-2030s. This next generation combat aircraft, which forms part of a wider combat air system, will exploit new technologies as they evolve to respond to the changing nature of the battlespace, addressing increasingly high-tech and complex threats and conflict.” Back in October, engineers working on the project revealed some of the highly innovative systems that are being developed for Tempest as part of the Future Combat Air System Technology Initiative (FCAS TI) programme. Here is what has been disclosed to the public so far. Leonardo, which is the project lead for electronics, is developing a new radar technology called Multi-Function Radar Frequency System. The new sensor will reportedly collect and process 10'000 times more data than existing systems, or “equivalent to the internet traffic of a large city every second”, providing the operators with a clear view of the battlespace and of potential targets. According to the company, complete sub-systems have already been built and successfully tested, paving the way eventually to future airborne testing. BAE Systems if working on another revolutionary concept, the “wearable cockpit”. In this case, the cockpit as we know it, full of switches, gauges and screens, becomes completely digital and all physical controls are replaced by Augmented and Virtual Reality systems. The new cockpit would be projected inside the pilot's helmet and completely customizable according to the pilot's preference and mission's needs. As human-AI teaming, a virtual copilot is being developed to interact with the pilot and provide support during the flight. “Psycho-physiological” technologies are also being trialed to study the operator's physical and cognitive processes to better understand increasing exertion, stress, workload and fatigue. According to the company, some of these technologies are being tested controlled test flight conditions aboard the Typhoon to inform further development. MBDA UK is also working on the wearable cockpit concept to integrate weapons systems information and operations. Rolls-Royce is working on the advanced combustion system technology that will power Tempest. The next-generation system is being designed to be hotter than previous ones to increase the efficiency of the engine, its range and speed, while reducing carbon dioxide emissions. Together with the higher-temperature combustion, there will be a new thermal management system that will use the turbine as a heat sink to recycle thermal energy, removing the need for overboard venting and improving the efficiency, and an increased electrical power production, reportedly in the order of one megawatt, that will be used to power all the aircraft's subsystems. This follows the assessment by Rolls Royce that future fighter aircraft will have unprecedented levels of electrical power demand and thermal load that need to be managed accordingly to maintain the airframe's low observability. Being more specific, the company stated that they will integrate an Electrical Embedded Starter Generator that will function both as an APU and as an electrical generator after the engine is spooled up. The Tempest is expected to have also his own loyal wingman, currently being developed as the Lightweight Affordable Novel Combat Aircraft (LANCA) concept. According to the MoD, LANCA will offer “increased protection, survivability and information for the manned aircraft – and could even provide an unmanned combat air ‘fleet' in the future.” A demonstration project, called “Moquito” and comparable to the Skyborg program of the U.S. Air Force, is currently in its first phase of evaluation. Three teams, Boeing Defence UK, Team Avenger (led by Blue Bear Systems Research), and Team Blackdawn (Callen-Lenz, Bombardier Belfast and Northrop Grumman UK), submitted designs for the flight demonstrations phase, which could begin in 2022-2023, after two finalists are selected during second phase of evaluation. LANCA will reportedly be a transonic aircraft costing one-tenth of a fighter aircraft, able to employ multi-role sensors, Electronic Warfare suites and both air-to-air and air-to-surface weapons. The unmanned aircraft project, led by the RAF Rapid Capabilities Office and the Defence Science and Technology Laboratory, originated in 2015, three years before the Tempest announcement. While a timeline for its entry into service has not been disclosed, the LANCA may be first deployed alongside the Typhoon and the F-35, before the entry into service of the new Tempest in 2035. https://theaviationist.com/2020/12/09/new-images-of-the-tempest-sixth-generation-aircraft-revealed-during-uk-industry-engagement-event/

  • F-35 stress tests raise possibility of longer service life

    F-35 stress tests raise possibility of longer service life

    SOURCE: FLIGHTGLOBAL.COM, BY: GARRETT REIM After completing static, drop and durability testing on the F-35A, Lockheed Martin believes that early results indicate potential for an increased service life certification of the stealth fighter. The F-35's service lifetime is designed to be 8,000h, but each test airframe is required to successfully complete two lifetimes of testing, the equivalent of 16,000h. The F-35A exceeded the requirement by completing three full lifetimes of testing, 24,000h, prompting Lockheed to moot the potential service-life extension. “We look forward to analyzing the results and bringing forward the data to potentially extend the aircraft's lifetime certification even further,” said Greg Ulmer, Lockheed Martin's vice president and general manager of the F-35 program. “Already certified for one of the longest lifetimes of any fighter, an increase would greatly reduce future costs for all F-35 customers over several decades to come.” The USAF plans to fly the F-35A until at least 2070, so a longer lifespan per aircraft may allow the service to reach that goal without having to purchase new fighters. However, as aircraft age they become more expensive to maintain and operate, making it unclear if a service life extension of the F-35A would be economical. The F-35A airframe completed its testing at BAE Systems in Brough, England. The F-35B and C variants were tested at Lockheed Martin's facility in Fort Worth, Texas, though the company did not release the results for those variants. All variants will eventually undergo final teardown inspections at the National Institute for Aviation Research in Wichita, Kansas. https://www.flightglobal.com/news/articles/f-35-stress-tests-raise-possibility-of-longer-servic-451964
