  Armed Services committees and the election: Here’s what we know

  By: Joe Gould WASHINGTON — As results for key congressional races and the presidency continue to roll in, several Senate Armed Services Committee leaders are still battling tough races. But here is what we do know, as of mid-morning Thursday. This story will be updated as results come in: • Georgia Republican Sen. David Perdue, the chairman of the Seapower Subcommittee, is leading in his race against Democrat John Ossoff, potentially denying Democrats what would have been a vital pickup for seizing control of the Senate. It's also too soon to call the race between Vice President Joe Biden and President Donald Trump for the state's 16 electoral votes. Democratic hopes of controlling the Senate for the first since 2015 appear to be slipping. To win the Senate, Democrats would have to gain three seats if Biden prevails against Trump, or four seats if Trump wins the election. • Senate Military Personnel Subcommittee Chairman Thom Tillis, R-N.C., led challenger Cal Cunningham by 96,000 votes and declared victory Wednesday, but Cunningham refused to concede while more than 117,000 absentee ballots were outstanding. • Senate Readiness and Management Support Subcommittee Chairman Dan Sullivan, R-Alaska, on Thursday morning appeared to have a 60,000-vote lead on Independent challenger Al Gross, with only half the votes counted. However, Alaska's tally is expected to take days as officials count mail-in ballots. • Sen. Joni Ernst, R-Iowa, had a similarly tough race but denied Democrats what would have been a key pickup for seizing control of the Senate. Ernst, the Emerging Threats and Capabilities Subcommittee chair and a member of Senate Republican leadership, is the first female combat veteran elected to Congress. • Michigan Democrat Sen. Gary Peters, the ranking member on the Emerging Threats and Capabilities Subcommittee, prevailed Wednesday night in a razor-tight race against businessman and Iraq war veteran John James. Hours after Biden defeated Trump in the state, Peters was roughly 60,000 votes ahead. • Senate Armed Services Committee Chairman Jim Inhofe, R-Okla., and ranking member Sen. Jack Reed, D-R.I., both won reelection handily, and if the Senate stays in Republican hands, they will almost certainly stay in their leadership roles. Senate Airland Subcommittee Chairman Tom Cotton, R-Ark., had no Democratic challenger and won reelection. Senate Cybersecurity Subcommittee Chairman Mike Rounds, R-S.D., also won. New Hampshire Democrat Sen. Jeanne Shaheen, another senior member of SASC, easily won a third term. All three were projected wins. • SASC Republican Sen. Martha McSally, the Air Force's first female fighter pilot to fly in combat, lost to Mark Kelly, an astronaut and retired Navy captain, in Arizona. She has yet to concede, however. • SASC Democrat Sen. Doug Jones, D-Ala., lost decisively to Republican opponent Tommy Tuberville. • House Armed Services Committee Chairman Adam Smith, D-Wash., soundly defeated his Republican challenger, while two lead Republican contenders to replace Rep. Mac Thornberry, R-Texas, as ranking member ― Reps. Mike Turner of Ohio and Mike Rogers of Alabama ― also won reelection. • Two Democratic freshmen on HASC ― Reps. Kendra Horn of Oklahoma and Xochitl Torres Small of New Mexico ― lost seats that Democrats flipped in 2018. As of Wednesday afternoon, Rep. Anthony Brindisi, D-N.Y., was trailing his Republican challenger but refused to concede until absentee ballots are counted. • Nebraska Republican Rep. Don Bacon, a former Air Force one-star general whose policy positions sometimes clashed with Trump, carved out a reelection win. Because Nebraska awards its electoral votes by congressional district, NE-02 was also a crucial win for Biden. • Rep. Elissa Slotkin, D-Mich., won reelection. Slotkin, a former CIA analyst and Pentagon official, is at the top of an influential class of Democratic freshmen who have hands-on national security experience. Addressing supporters Wednesday, she reportedly said Biden will win in Michigan, but there may be a tumultuous transfer of power. https://www.defensenews.com/congress/2020/11/04/armed-services-committees-and-the-election-heres-what-we-know/

  The next few months are ‘critical’ for the Army’s new helicopter engine

  By: Aaron Mehta WASHINGTON — The Army's Improved Turbine Engine Program is facing a “critical” stretch which will determine whether testing on the engine will occur on time or be delayed, thanks to challenges related to the COVID-19 pandemic, a pair of Army officials said Wednesday. Patrick Mason, the program executive officer for Army aviation, and Brig. Gen. Walter Rugen, the director for future vertical lift inside Army Futures Command, said that the service has finished its component critical design review (CDR) process, and has moved on to its full program CDR, a key milestone before moving into testing. However, “given COVID and all of the factors that have gone on with COVID,” the plan to have the full CDR done during second quarter has been pushed to third quarter, Mason said at an event hosted by the Heritage Foundation. ITEP is “the number one watch item we've had across the future vertical lift portfolio for COVID impacts,” Mason said, because “hardware needs to be coming in the latter part of this year so we can test at the component level, assemble into the engine, and then go to first engine test.” “So that's going to be critical over the next month to two months, to see where we stand on hardware deliveries with that, and then whether or not we will reach first engine test at the time that we had originally stated,” he said, noting the plan is for engine tests to proceed in 2021. Mason also noted that the delay is less dramatic than it may seem, because the original plan for ITEP called for the full CDR to be completed in the fourth quarter of this year; the Army felt it was ahead of schedule enough to shift that target to second quarter, until COVID caused the delay. In other words, CDR being completed in Q3 still means the program is ahead of its original baseline. General Electric Aviation won the $517 million award for the engineering, manufacturing and development phase in February 2019. The requirements included developing a 3,000 shaft horsepower engine that reduces fuel consumption by 25 percent and increases service life by 20 percent compared to the legacy T700 currently used in the Army's AH-64 Apache and UH-60 Black Hawk helicopters. In addition to replacing the engines on those two leacy platforms, ITEP is expected to power the Future Attack Reconnaissance Aircraft, or FARA design. For the heavier future rotorcraft known as the Future Long-Range Assault Aircraft, or FLRAA, the Army is looking at a heavier engine design, although the companies competing for the design will have the ability to pick their own engine designs as part of their pitches. “We really think the efficiencies there with a two engines strategy across all of Army aviation's tactical fleet would be a powerful way to go at both readiness and affordability concerns,” said Rugen. https://www.defensenews.com/land/2020/06/10/the-next-few-months-are-critical-for-the-armys-new-helicopter-engine/

  NFAC Tests Next-Generation Military Helicopter

  Wind Tunnel Test Designed To Validate The Aerodynamic Performance And Flight Mechanics Of Sikorsky's X2 Technology Aircraft The U.S. Army is looking to improve its aviation technology and recently called upon the AEDC National Full-Scale Aerodynamics Complex at Moffett Field in Mountain View, CA, to advance this effort. Engineers from Sikorsky Aircraft Corporation and The Boeing Company, in partnership with the U.S. Army Combat Capabilities Development Command Aviation & Missile Center Army Aviation Development Directorate, recently conducted a series of tests at NFAC to support the development of the SB>1 DEFIANT, a military helicopter being developed for the Army's Joint Multi-Role Technology Demonstrator (JMR TD) program. The goal of this wind tunnel test was to validate the aerodynamic performance and flight mechanics of Sikorsky's X2 Technology aircraft. These configurations, which are being utilized on the SB>1 DEFIANT, include a lift-offset coaxial rotor system, composite fuselage and rear-mounted pusher propulsor that provides increased speed. The SB>1 DEFIANT, which made its first flight in March, is a technology demonstrator for a medium-lift utility helicopter. Future uses of this type of air vehicle could include attack and assault, troop transport or MEDEVAC. The testing was conducted throughout the first half of 2019 and concluded in mid-June. To accomplish the tests, a 1/5 scale model of the SB>1 DEFIANT airframe with powered coaxial main rotors was placed in the NFAC 40- by 80-foot wind tunnel. Measurements included forces and moments on the various components, as well as fuselage, empennage and blade surface pressures. David Wang, NFAC test engineer, said the recent tests expanded on data collected from a JMR wind tunnel entry conducted at NFAC in 2016 by gathering data at faster speed ranges. “From the NFAC perspective, the wind tunnel test was successful,” Wang said. “The test customer was able to collect performance and handling qualities data for their subscale model up to their maximum design flight speed.” Data collected during the recent tests is undergoing review and analysis. It is unknown at this time if there will be future testing of the SB>1 DEFIANT model at NFAC. The full-scale SB>1 DEFIANT flight demonstrator is currently undergoing ground and flight tests at Sikorsky's flight test facility. According to the Sikorsky-Boeing JMR Team, data from SB>1 DEFIANT will help the Army develop requirements for new utility helicopters expected to enter service in the early 2030s. A previous DOD study concluded that upgrades to the aging DOD rotary wing aviation fleet would not provide the capabilities required for future operations. Significant improvement in several attributes of fleet aircraft, such as speed, payload, range, survivability and vertical lift are required to meet future needs. It was determined this improvement could be achieved through application of new technologies and designs. To accomplish its goal, the Army has been executing a science & technology (S&T) effort to mitigate risk associated with maturity of critical technologies, feasibility of desired capabilities and cost of a technical solution. An aspect of this effort is the air vehicle development associated with the JMR TD program. JMR TD is the alignment of Army Aviation's S&T with the Future Vertical Lift initiative, which seeks to develop a new family of system to modernize and replace the government's current fleet of rotorcraft. According to the Army, the intent of the JMR TD is to mitigate risk for the Future Vertical Lift program through means that include the testing of advanced technologies and efficient vehicle configurations. NFAC, managed and operated by Arnold Engineering Development Complex (AEDC), is the largest wind tunnel complex in the world. It consists of both the 40- by 80-foot and 80- by 120- foot wind tunnels. These tunnels, which share a common drive system, are primarily used for aerodynamic and acoustic tests of rotorcraft and fixed wing, powered-lift V/STOL aircraft and developing advanced technologies for these vehicles. Both subscale and full-scale models are tested at NFAC. The speed range of the 40- by 80-foot wind tunnel test section is continuously variable from 0 to 300 knots, while the speed range in the 80- by 120-foot wind tunnel section is continuously variable from 0 to 100 knots. http://www.aero-news.net/index.cfm?do=main.textpost&id=021bcb83-4df9-4253-b7a3-ff3805b7b16a
