  New USAF Materials Hint At High-Altitude Role For B-21

  Steve Trimble The design of the Northrop Grumman B-21's trailing edge has led to speculation about a high-altitude role for the secretive stealth bomber, and new U.S. Air Force statements appear to confirm that analysis. As the U.S. Air Force enters a legally required environmental impact review process for basing the new bomber, service officials disclosed a few new details about the design on large poster boards displayed at public meetings since February. The posters are now available on B21EIS.com, a clearinghouse web site set up by the Air Force to share data during the year-long process to complete the final environmental impact statement. “The B-21 is not expected to use low altitude training routes,” the Air Force poster says. The B-2 was originally conceived as a high-altitude bomber, but a last-minute requirements change during the development phase forced Northrop Grumman to redesign the bomber for a low-altitude mission. As a result, the trailing edge was transformed from a simple W-shape to the sawtooth design seen today. The B-2, like the preceding B-52 and B-1B fleets, need low-altitude training routes. The renderings of the B-21 released by the Air Force so far reveal a trailing edge that resembles the original, high-altitude design for the B-2. The Air Force has never confirmed operational details about the future stealth bomber. Another comment on the Air Force's poster provides the first official description of the B-21's acoustic signature, as well as the performance of the engines. “The B-21 engine noise is expected to be quieter than the B-1B and about the same or quieter than the B-2,” the poster says. Previously, the only detail released by the Air Force about the B-21's engines is that Pratt & Whitney is named as one of seven of Northrop's suppliers. The poster data appears to confirm expectations that the B-21 would use a non-afterburning engine, like the similarly subsonic, flying wing-shaped, B-2. The supersonic B-1B is powered by afterburning engines. The Air Force has selected Ellsworth Air Force Base in South Dakora as the site for the first B-21 operational squadron, followed by Dyess AFB in Texas and Whiteman AFB, Missouri. The environmental impact review is evaluating Ellsworth and Dyess for the main operating beddown 1 location. https://aviationweek.com/defense-space/aircraft-propulsion/new-usaf-materials-hint-high-altitude-role-b-21

  General Atomics to make first transatlantic flight of a MALE RPA

  Written by Wings Staff General Atomics Aeronautical Systems Inc. plans to make the first-ever transatlantic flight of a Medium-altitude, Long-endurance (MALE) Remotely Piloted Aircraft (RPA). GA-ASI's company-owned MQ-9B SkyGuardian RPA is scheduled to fly from the company's Flight Test and Training Center in Grand Forks, North Dakota, to Royal Air Force (RAF) Fairford in Gloucestershire, UK. The aircraft will then be on static display July 13 to 15 for the Royal International Air Tattoo (RIAT) airshow being held at RAF Fairford. The flight and display will help commemorate the RAF's centenary celebration (RAF100). “GA-ASI is proud to have supported the RAF over the past decade with our MQ-9 Reaper. In honour of the RAF100 celebration, and to demonstrate a new standard in RPA flight endurance, we will fly SkyGuardian across the Atlantic,” said Linden Blue, CEO, GA-ASI. “Given the distinguished 100-year history of the RAF, we believe that this flight is an appropriate way to celebrate the RAF's position as a leader in innovation.” In 2017, GA-ASI and the RAF marked the 10-year anniversary of RAF MQ-9 operations, which coincided with the RAF completing 100,000 flight hours with its Reaper force. The entire Reaper fleet has completed over two million flight hours to date and is comprised of over 300 aircraft within the NATO alliance. The RAF is acquiring MQ-9B SkyGuardian as part of its PROTECTOR RG Mk1 program. MQ-9B is the latest evolution of GA-ASI's multi-mission Predator B fleet. GA-ASI named its baseline MQ-9B aircraft SkyGuardian, and the maritime surveillance variant SeaGuardian. MQ-9B is a certifiable (STANAG 4671-compliant) version of the MQ-9 Predator B product line. The company explains its development is the result of a five-year, company-funded effort to deliver a RPA that can meet the airworthiness type-certification requirements of various military and civil authorities, including the UK Military Airworthiness Authority (MAA) and the U.S. FAA. GA-ASI explains type-certification, together with an extensively tested collision avoidance system, will allow unrestricted operations in all classes of civil airspace. Several important MQ-9B milestones were achieved in recent months, explains the company, including the first FAA-approved flight for a company-owned RPA through non-segregated civil airspace without a chase aircraft, and an endurance record of more than 48 hours of continuous flight. As part of the transatlantic flight, GA-ASI has partnered with Inmarsat, a provider of global mobile satellite communications (SATCOM) services. Inmarsat's SwiftBroadband SATCOM will be used by the MQ-9B's ground control station to communicate and control the aircraft and also will be used in the RPA's final configuration for capabilities such as automatic takeoff and landing. https://www.wingsmagazine.com/news/general-atomics-15726
