  Bell’s V-280 Valor hits 200 hours of flight time 3 years after first flight

  By: Jen Judson WASHINGTON — Bell's technology demonstrator designed to show the Army the realm of the possible in Future Vertical Lift capability has flown 200 hours since its first flight three years ago, according to Keith Flail, the company's executive vice president for advanced vertical lift systems. The V-280 Valor tiltrotor parted ways with the tarmac for the first time on Dec. 18, 2017, at 1:59 p.m. CDT at a Bell facility in Amarillo, Texas. Defense News reported the flight as the aircraft was still in the air, but the aircraft logged roughly 15 to 20 minutes before returning to solid ground. Since then Bell's clean-sheet-designed aircraft has flown more than 150 sorties, Flail told Defense News in a recent interview, and the extensive effort has driven down risk for the Future Long-Range Assault Aircraft program for the U.S. Army. Valor hit the 200 flight hour mark on Dec. 4, Flail said. The Army wants to field FLRAA — an aircraft expected to fly twice as fast and twice as far as a conventional helicopter — by 2030. Bell is gearing up to compete head-to-head with a Lockheed Martin's Sikorsky and Boeing team, which built the only other flying technology demonstrator in the effort leading up to a program of record. The SB-1 Defiant coaxial helicopter flew for the first time in March 2019 after struggling with rotor blade manufacturing problems and working through other more minor kinks. Both companies have entered a competitive development and risk reduction phase awarded in March 2020 ahead of the FLRAA program. The Army announced this month that it intends to proceed into a competition between just Sikorsky-Boeing and Bell to produce FLRAA. Valor has been put through its paces, completing key performance parameters and continuing to prove out possible threshold and objective requirements for FLRAA. The aircraft had its first public flight in June 2018 where it reached cruising speeds of 195 knots and was put through its paces in hover mode. In May 2019, the aircraft completed low-speed agility maneuver testing — which made up the final key performance parameters left to prove out with the system as part of the technology demonstration phase. Valor flew autonomously for the first time a year ago. The aircraft performed an autonomous takeoff, conversion into cruise mode, precision navigation to various waypoints, loiter maneuvers, conversion into vertical-takeoff-and-landing mode, and landed autonomously. Other achievements include demonstrating an integrated system from Lockheed Martin that provides the pilots and aircrew a 360-degree view through the skin of the aircraft in the spring of 2019. And in early 2020, Bell also integrated the Tactical Common Data Link and transmitted information between Valor and the ground station to include basic flight data and showed it would be able to provide targeting information to help long-range precision fires weapons hit targets more accurately, according to a Dec. 17 company statement. In the same flight, Bell demonstrated sling-load capability, Flail said. “During a single sortie, the team performed multiple cargo lifts to demonstrate the procedure and coordination of ground crew, aircraft, crew chief, pilots and the behavior of the loads for the V-280,” the statement notes. Over the course of the technology demonstration period, Flail added, the aircraft was also able to show its reliability and availability. “This configuration of tiltrotor really shows how robust it is in terms of reliability and availability because one of the tricks with proving that is you have to accumulate enough data to show that you do have a reliable system,” he said. “A lot of your critical items, your gearboxes and your blades ... those are typical cost drivers downstream and today, we still have the original six blades and gearboxes on this aircraft.” https://www.defensenews.com/land/2020/12/17/bells-v-280-valor-hits-200-hours-of-flight-time-3-years-after-first-flight/

  AF Seeks Freedom To Shift $$ Between Space Programs

  "[T]he way that the Air Force and now Space Force put their budget submissions into Congress, it puts all of the programs into individual program elements," Roper said, "and that's like locking [each] program into a little financial prison." By THERESA HITCHENSon April 16, 2020 at 4:28 PM WASHINGTON: The Air Force wants Congress to approve new powers allowing the service to fund space acquisition in ‘blocks' that would allow it more freedom to shift funds from one specific program to another, says service acquisition head Will Roper. The idea, he told reporters today, is to give the Space Force acquisition authorities that mimic those used by fast-moving and highly capable organizations such as the Special Capabilities Office and the NRO. The mechanism: putting multiple programs into one budgetary program element (PE) number so priorities can be juggled or monies shifted to ailing programs to help them cope with cost or schedule overruns. “One of the things that we are very passionate about for space acquisition is trying to consolidate the space portfolio into a few number of program elements,” Roper said, noting that when he headed the SCO “we funded almost all of our programs out of one program element. That's really important because it let me optimize the portfolio of programs, not just do individual programs,” he explained. “Well, the way that the Air Force and now Space Force put their budget submissions into Congress, it puts all of the programs into individual program elements, and that's like locking [each] program into a little financial prison.” Although it is true that other organizations with acquisition powers — including SCO, NRO and the Missile Defense Agency — have such flexibility, it is unclear whether Congress will acquiesce to the same for the Space Force. The 2016 NDAA created a new “major force program” — MFP 12 — for DoD reporting on the national security space budget precisely to overcome: a) the lack of transparency in DoD budgeting for space programs, and b) the long-standing Air Force practice to shift space funds to air power programs that were suffering setbacks. However, an MFP does not allow the Air Force or other space services to move money around without congressional assent. As late as the 2020 budget request, DoD admitted that it still had not sorted out how exactly to meet the MFP-12 requirement as it was still developing standard practices for determining what should be included or not. Joshua Huminski, director of the National Security Space Program at the Center for the Study of the Presidency and Congress (CSPC), said wryly that the Air Force request is likely to “require very artful selling to Congress.” He explained in a phone conversation today that congressional leaders already are keeping the Air Force on a short leash regarding space acquisition. Roper said the request for such new authorities will be included in the space acquisition report Air Force Secretary Barbara Barrett is required to send to Congress under language in the 2020 National Defense Authorization Act (NDAA). That report was due March 31 but has yet to be transmitted. Roper said the report is finished but is being reviewed by Defense Secretary Mark Esper. As I've reported, Barrett's report will punt on the question of whether the NDAA-required Space Force acquisition executive will be a fully separate office or will be organized in some fashion as a subunit of Roper's current shop. It's no secret that Roper has strenuously opposed a fully bifurcated space acquisition office. Roper confirmed today that the pending report is concentrating on how the service hopes to use its current, and newly proposed, acquisition authorities to speed the often decades-long process of moving new space capabilities from design to procurement. He explained that the Air Force will wait until after Congress decides on its proposal for future space acquisition authorities before circling back to the organizational question — in effect, meaning that the service will not address the issue until after the 2021 NDAA is passed. “And then once we determine what will be given to us or not, then for round two, we'll look at what's the right way to organize with these new authorities, and at that point we'll take on the question of whether there should be one or two service acquisition executives,” he elaborated. The service has until October 2020 to establish the controversial new space acquisition post. https://breakingdefense.com/2020/04/af-seeks-freedom-to-shift-between-space-programs
