    Romania set to choose four new corvettes, frigate upgrade

    Richard Scott, London and Luca Peruzzi, Genoa - Jane's Navy International Romania's Ministry of Defence is nearing a decision on the procurement of new multirole corvettes after receiving final bids at the beginning of October from Damen Schelde Naval Shipbuilding of the Netherlands, Italy's Fincantieri, and France's Naval Group. The EUR1.6 billion (USD1.85 billion) programme covers the acquisition of four corvettes, as well as the combat system modernisation of the Romanian Navy's two ex-UK Royal Navy Type 22 frigates Regina Maria and Regele Ferdinand . A source selection is scheduled for 26 October, although industry sources suggest this could slip by a number of weeks. Romania's requirement calls for a 2,500-tonne class multipurpose ship with capabilities across anti-submarine warfare, anti-surface warfare, anti-air warfare, electronic warfare, naval gunfire support, and search and rescue. The design is also required to provide aviation facilities suitable for an IAR 330 Puma 10-tonne helicopter and a shipborne unmanned aircraft system. In line with Romanian stipulations for local industry participation, all three contenders are proposing build and in-service support in conjunction with subsidiaries or partners based in country. Romania has asked for the first corvette to be delivered inside three years, with the programme to be completed in seven years. Damen Schelde Naval Shipbuilding is bidding a variant of its SIGMA 10514 design with sister yard Damen Shipyards Galati. To meet the Romanian requirement, Daman has specified a Thales Nederland combat management system (CMS)/sensor fit, the Raytheon Evolved SeaSparrow Missile System and Boeing Harpoon Block II anti-ship missiles. The underwater warfare suite would be provided by General Dynamics Mission Systems-Canada. Fincantieri, which owns the Vard Braila and Tulcea shipyards in Romania, is offering a customised variant of the Abu Dhabi corvette previously built for the United Arab Emirates. It is likely that Vard Braila would be the focal point for both construction and in-service support if Fincantieri is selected. https://www.janes.com/article/83937/romania-set-to-choose-four-new-corvettes-frigate-upgrade

    T-X competition to end in September with selection of new USAF trainer aircraft

    2018-08-30 WILLIAM KUCINSKI Officials will soon award a 350-unit contract to one of three competing aircraft teams. According to officials, the U.S. Air Force (USAF) will select a new trainer aircraft by September 30 – before the end of the 2018 fiscal year. The aircraft will be one of the three remaining next-gen trainer candidates from the USAF's ongoing T-X competition, either the clean-sheet T-X from Boeing and Saab, the T-50A from Lockheed Martin and Korea Aerospace Industries, Ltd. (KAI), or the T-100 from Leonardo DRS. The USAF will replace its aging fleet of Northrop T-38 Talon supersonic jet trainers with 350 new aircraft from the T-X competition, spending approximately $16 billion to acquire and maintain the new trainers over the course of their service life – one of the largest USAF contracts in recent times. The seasoned T-38 has been in use since 1961, training nearly 50,000 pilots who would later fly aircraft like the Boeing B-52 Stratofortress, Lockheed SR-71 Blackbird, McDonell Douglass F-15 Eagle, and Fairchild Republic A-10 Thunderbolt II. However, as the USAF transitions employs more and more cutting-edge technologies, a next-gen trainer is needed to better facilitate fifth-gen fighter aircraft pilot training for the Lockheed Martin F-22 Raptor and F-35 Lighting II. The winning T-X aircraft will serve as a platform to acclimate pilots to aircraft with extreme agility, full-sensor fusion, integrated avionics, supercruise, and consolidated and integrated battlespace management technologies. Industry analysts currently favor the Lockheed/KAI T-50A – based on KAI's T-50 trainer used by South Korea's Republic of Korea Air Force and co-developed by Lockheed Martin, manufacturer of the F-22 and F-35; and the Boeing/Saab T-X – which, as a completely new design – benefited from additional development time due to the T-X competition's repeatedly protracted award announcement. While speculation has floated that the T-X award announcement would occur during the Air Force Association's Air, Space & Cyber (ASC) Conference from Sept. 17-19, those close to the program hinted at a decision coming through the following week of Sept. 24. https://www.sae.org/news/2018/08/t-x-competition-to-end-in-september-with-selection-of-new-usaf-trainer-aircraft

  • New policy addresses 3D parts for Army aircraft

    New policy addresses 3D parts for Army aircraft

    By Courtesy As the Army explores the potential of some advanced manufacturing methods and 3D-printed parts to maintain and sustain its aviation fleet, recently published guidance aims to strike a balance between safety, improvements to readiness and escalating costs. Advanced manufacturing refers to new ways of making existing products and the production of new products using advances in technology. Advanced manufacturing includes additive manufacturing, a process of joining materials to make parts from 3D-model data. Additive manufacturing differs from the traditional subtractive process that cuts away material to shape and produce parts. The U.S. Army Aviation and Missile Command recently published a policy memorandum addressing advanced manufacturing for Army aircraft parts, components and support products. “Evolving technologies create a unique challenge as we determine the airworthiness of parts when the data is immature, incomplete or even non-existent,” said AMCOM Commander Maj. Gen. Todd Royar, who serves as the Army's airworthiness authority, responsible for ensuring the safety of the service's aircraft components. As enduring aircraft, like the UH-60 Black Hawk helicopter, continue in service, the supply system with face challenges with obsolescence, meaning parts that are difficult to acquire or receive no bids from potential vendors to manufacture. As the Army keeps pace with technology, advanced manufacturing creates opportunities to optimize long-term sustainment efforts. The Army established a partnership recently with Wichita State University's National Institute for Aviation Research (NIAR) to create a “digital twin” of an aging Black Hawk model. “One of the primary tasks in this effort is to convert all legacy 2D drawings of this aircraft into modern 3D parametric models,” said John Tomblin, senior Vice-President for Industry and Defense Programs and Executive Director of NIAR at Wichita State University. “This will allow the Army to source parts that are out of production as well as use advanced techniques, such as additive manufacturing, to produce parts.” The digital twin opens a door to the 3D modeling and more opportunities to use parts made through additive manufacturing. The NIAR project is not the Army's only effort. Army Aviation is already using advanced manufacturing methods and 3D-printed parts to solve specific challenges. When several CH-47 helicopters experienced structural cracks at a certain portion of the frame assembly, an initial solution was to replace the entire frame assembly. “Replacing the entire assembly is a time-consuming task that also poses logistical challenges because replacements are difficult to obtain,” said AMCOM's Aviation Branch Maintenance Officer, Chief Warrant Officer 5 Michael Cavaco. Instead, engineers designed a solution to restore the cracked frames to their original strength by creating repair fittings using Computer-Aided Design models. “After five iterations of 3D-printing prototypes, test fit and model adjustments, a final design solution was achieved,” Cavaco said. Additionally, 3D printers have created several tools and shop aids that have benefitted the field. Many of these stand-alone items that support maintenance operations are authorized within Army technical manuals, depot maintenance work requirements or similar publications. While too early to predict overall cost and time savings, the advantages of advanced manufacturing are significant. The use of advanced manufactured parts will eliminate wait time on back-ordered parts that, ultimately, delay repairs. A key focus of AMCOM's AM policy is on inserting evolving technologies into enduring designs that have relied on traditional manufacturing processes throughout their acquisition lifecycle. However, future Aviation are benefiting as well from advanced manufacturing. The Improved Turbine Engine Program (ITEP) includes a number of advanced manufacturing elements. “ITEP benefits from advanced manufacturing include reduced cost, reduced weight, increased durability, and enhanced performance when compared to traditional manufacturing methods,” said Col. Roger Kuykendall, the project manager for Aviation Turbine Engines. “The benefits of AM stem from the unique capability to produce more complex hardware shapes while simultaneously reducing part count.” The fine details of airworthiness expectations asserted in this policy were crafted by a team of engineers at the U.S. Army Combat Capabilities Development Command Aviation and Missile Center, led by Chris Hodges, the current acting associate director for Airworthiness-Technology. Hodges said the new policy was drafted after his team collaborated with stakeholders from across the aviation enterprise, reaching across Army organizations and out to sister services and the Federal Aviation Administration. “We considered a lot of input and ultimately organized expectations and requirements by category, spanning from tools and shop aids to critical safety items,” Hodges said. “The resulting policy sets a solid foundation with room to grow and fill in details as the story evolves.” For Army aviation applications, advanced-manufactured parts and components will be managed under six categories that range from articles that support maintenance operations to those aviation critical safety items, whose failure would result in unacceptable risk. The designated categories prescribe for engineers and manufacturers the allowed materials and appropriate testing methodology for each particular part. The new guidance is not intended as a replacement for other existing policies that address advanced manufacturing. “We intend to be in concert with Army policies and directives that pertain to readiness, maintenance and sustainment,” Royar said. “Our policy provides a deliberate approach to ensure airworthiness and safety while determining where research and efforts may best supplement the supply chain and improve performance while balancing cost.” AMCOM Command Sgt. Major Mike Dove acknowledged the methodology must continue to mature in multiple areas before confidence grows in the ability to measure airworthiness qualification requirements for advanced-manufactured parts. “We fully support the maturation requirements for advanced-manufacturing technology, but not at the expense of flight safety,” Dove said. As Army aviation continues to pursue and include advanced-manufacturing methods, Royar noted the potential impact as the technology evolves. “Advanced manufacturing touches units, depots and the broader supply chain,” Royar said. “As we sustain our enduring aircraft and look to future systems, it is important that we keep pace with this and other emerging technologies for the sake of the warfighter.” https://www.army.mil/article/238868/new_policy_addresses_3d_parts_for_army_aircraft
