    New defense budget bill foresees US-Israel counter-drone cooperation

    By: Seth J. Frantzman JERUSALEM — For the first time, the National Defense Authorization Act includes a section on U.S.-Israel cooperation in countering unmanned aerial systems, in the fiscal 2019 version. The cooperation will identify “capability gaps” of the U.S. and Israel in countering UAVs and seek out projects to address those gaps to strengthen U.S. and Israeli security. The new cooperation envisions funding for research and development efforts and identifying costs that foresee close cooperation modeled on previous successful programs that Israel and the U.S. have collaborated on, including missile defense and anti-tunneling initiatives. Israel and the U.S. have been at the forefront of air defense cooperation for decades. U.S. Reps. Charlie Crist and Mike Johnson introduced in February a bill titled “United States-Israel Joint Drone Detection Cooperation Act.” Parts of the bill were included in the NDAA passed in both houses of Congress in July. “I am honored to have our bill included in the NDAA and to see it signed into law by President [Donald] Trump. This is an important step not only for our strongest ally in the Middle East but for the United States as well,” Johnson said in July. The president signed the NDAA into law on the afternoon of Aug. 13. The initiative foresees “joint research and development to counter unmanned aerial vehicles [which] will serve the national security interests of the United States and Israel.” Included as Section 1272 of the final NDAA presented to the president on Aug. 3, the cooperation contains five parts, including identification of the capability gaps that exist, identifying cooperative projects that would address the gaps, assessing the costs of the research and development, and assessing the costs of procuring and fielding the capabilities developed. Reports on the cooperation will be submitted to the congressional defense committees, the Senate Foreign Relations Committee and the House Foreign Affairs Committee. The threat of drones has increased in recent years. On Feb. 10 an Iranian-made drone entered Israeli airspace near the northern town of Beit Shean. It had flown from the T4 air base in Syria. Israel identified and tracked the drone from Syria and sent an Apache helicopter to shoot it down. The drone was revealed to be armed with explosives. Former Mossad chief Danny Yatom said in an interview in April that the drone was sophisticated and “an exact replica of the U.S. drone that fell in their territory,” referring to the American RQ-170 Sentinel, which was downed in Iran in 2011. Iran developed two drones based on the Sentinel, one called Shahed 171 and an armed version dubbed Saeqeh, which debuted in 2016. In 2012, Hezbollah used a drone to try to carry out surveillance of the Dimona nuclear reactor in southern Israel. “It's not the first time and it will not be the last,” warned Hezbollah leader Hassan Nasrallah. Conflict Armament Research reported in March 2017 that kamikaze drones using Iranian technology were being used by Houthi rebels in Yemen against Saudi Arabia and the United Arab Emirates. The UAE has sought to bring attention to this threat during the conflict in Yemen, in which a Riyadh-led coalition is fighting the Houthis. Drones were also used by the Islamic State group to attack U.S.-led coalition forces in Syria and Iraq. And Afghan officials reported an Iranian drone entered their airspace in August 2017. In September 2017, Israel used a Patriot missile to down a Hezbollah drone. Israel used Patriotmissiles twice to down Syrian UAVs near the Golan Heights demilitarized zone in July 2018. The U.S. reportedly used an F-15E Eagle to shoot down an Iranian-made Shahed 129 drone in June 2017 in Syria. The drone was heading for the U.S. base at Tanf, which is located in Syria near the Jordanian border. A systematic examination of the emerging drone threat is in the works. The U.S. Defense Department has been allocating resources to counter UAVs, with U.S. Central Command requesting up to $332 million over the next five years for efforts to counter drones. The U.S. Army has been looking for new missiles to defend against a variety of threats, including drones. This will include the Expanded Mission Area Missile and may include other Israel missiles such as the Tamir interceptor for use with a multimission launcher. https://www.defensenews.com/unmanned/2018/08/13/new-defense-budget-bill-foresees-us-israel-counter-drone-cooperation/

  • Military Technology Could Bolster Bell’s Commercial Helicopters

    Military Technology Could Bolster Bell’s Commercial Helicopters

    Tony Osborne October 30, 2020 Bell is pondering how to incorporate advanced technologies developed for its future military platforms into its commercial rotorcraft. Since its rebranding as more of a technology company than a helicopter OEM, CEO Mitch Snyder has been pushing the company on a course of innovation, investing in autonomous flight and electric propulsion as well as advancing defense capabilities. But there appears to be little obvious gain for Bell's line of civil rotorcraft. In the last couple of years, its commercial helicopters have received only fairly minor upgrades. The Model 407GXi light single-engine platform had its avionics upgraded so that it can fly under instrument flight rules, while the Model 412 medium twin received new avionics and uprated power. Yet both upgrades were essentially spun off from modifications for military programs. The 407 update was developed for the U.S. Navy's rotary-wing trainer requirement, which Bell lost to Leonardo, and the 412EPi was born from the type's selection by Japan for its UH-X military utility requirement. Bell's restraint in further developing commercial rotorcraft likely is due to its prolonged effort to bring the new Model 525 to market. Nor is it a great time to bring a new aircraft to market. Sales remain stubbornly slow in the aftermath of a fall in energy prices that dramatically reduced orders from the lucrative oil-and-gas support market. Progress in bringing the fly-by-wire, 9.3-metric-ton 525 super-medium to market—it was launched in 2012 and flown for the first time in 2015—has been painfully slow, in part due to the fatal loss of one prototype but also due to the need to convince certification authorities of fly-by-wire technology benefits. “The hurdle is higher now to try and get [the 525] certified,” Snyder told Aviation Week during a virtual roundtable on Oct. 19. “This technology brings all these benefits and makes the aircraft safer. . . . You have to walk them through and give them time to understand it,” he said. Snyder believes things are on track. “We feel very good about getting certified in 2021,” he added, noting that the company is finishing up testing and preparing for the submission of certification documentation to the FAA. He said Bell is continuing to evaluate new commercial platforms, although the cost of development and certification is prohibitive. “We're always looking to see if there's a clean-sheet out there that we may want to do,” he said. “But I can tell you, at least right now, our focus has been around derivatives to our military products and more about adapting upgrades to our existing models.” The approach appears to be in line with his views at last year's Paris Air Show, where he suggested Bell may not develop a new clean-sheet commercial conventional rotorcraft beyond the 525. One area of opportunity could be development of a single-engine medium helicopter, he hinted, building on Bell's Model 360 Invictus prototype for the U.S. Army's Future Attack Reconnaissance Aircraft (FARA) requirement. “Bell's got a lot of single-mediums out there,” said Snyder, noting that hundreds of Model 204/205 Iroquois helicopters remain in service with militaries, civilian operators and government agencies. Operators have become reliant on twin-engine helicopters, particularly because in some parts of the world, notably Europe, single-engine rotorcraft are banned from flying over urban areas. But Snyder said the 360 Invictus also features a supplemental power unit that can act as an auxiliary power unit as well as provide additional performance or auto-rotation power, and could be an enabler for a single-engine medium. It is possible that Bell is looking at a military utility variant of the 360 Invictus, pairing the aircraft with the attack version in the same way that its UH-1Y Venom and AH-1Z Viper platforms have built on the Huey and Cobra. Such a platform could receive interest from the U.S. special operations community, which is looking to replace the Boeing AH-6/MH-6 Little Bird family. Officials have noted that they would like to be able to adapt a FARA platform to carry troops. Sikorsky's Raider X can do so, but the Bell FARA cannot, until a more utilitarian version emerges (AW&ST June 1-14, p. 28). The Army's selection of Bell's V-280 tiltrotor as the larger Future Long-Range Assault Aircraft could enable a commercial spinoff of the platform, Snyder suggests. Bell is also looking to make commercial use of its Electrically Distributed Anti-Torque (EDAT) technology, a ducted electric tailrotor system tested on a Bell 429 light-twin. Flight tests for it were only revealed in February, despite the aircraft's flights in plain sight from its Mirabel, Quebec, facility since May 2019. Testing showed that the EDAT reduced noise levels, but there were also benefits in terms of safety, enabling the option of switching off the anti-torque system while the engines and main rotor are still turning. The EDAT eliminates complex tailrotor gearboxes and shafts and requires less costly inspections and maintenance as well. “We pulled in off-the-shelf technologies to make the demo occur within one year,” said Snyder. “Now we're evaluating what the real technology needs to be as far as repackaging it in the weight and size that we require.” Snyder said the EDAT technology will be aimed at a commercial rotorcraft, but for which product line or when it might be commercially available has yet to be decided. https://aviationweek.com/aerospace/aircraft-propulsion/military-technology-could-bolster-bells-commercial-helicopters

    Boeing and Etihad Broaden Sustainability Alliance by Testing Innovations on ecoDemonstrator 787

    Seattle, July 20, 2020 /PRNewswire/ - Boeing [NYSE:BA] and Etihad Airways will use a 787-10 Dreamliner to test ways to reduce emissions and noise as part of the aerospace company's ecoDemonstrator program before the airline accepts delivery of the airplane this fall. The collaboration, which includes extensive sound measurement testing with industry partners, builds on a strategic sustainability alliance Boeing and Etihad formed in November 2019. "This is the latest program under Etihad's industry-leading strategic partnership with Boeing, focusing on innovating real-world solutions to the key sustainability challenges facing the aviation industry," Etihad Aviation Group Chief Executive Officer Tony Douglas said. "The ecoDemonstrator program is founded on innovation and sustainability — and these are core values for Etihad Airways, Abu Dhabi and the United Arab Emirates. Etihad and Boeing see a great opportunity to collaborate and share knowledge to minimize the impact of aviation on the environment." The ecoDemonstrator program utilizes commercial aircraft to test technologies that can make aviation safer and more sustainable now and into the future. The 2020 program, which will begin testing in August, is the first to use a Boeing 787-10. "Industry collaboration is a key aspect of Boeing's ecoDemonstrator program that enables us to accelerate innovation," said Stan Deal, Boeing Commercial Airplanes president and CEO. "We're proud to broaden our sustainability partnership with Etihad Airways by testing promising technologies that can reduce emissions, help commercial aviation meet our climate goals, and allow the industry to grow in a responsible manner that respects our planet and its natural resources." Boeing and Etihad will work with industry-leading partners, including NASA and Safran Landing Systems, to conduct aircraft noise measurements from sensors on the airplane and the ground. The data will be used to validate aircraft noise prediction processes and the sound reduction potential of aircraft designs, including landing gear, that are modified for quieter operations. In addition, a flight will be conducted during which pilots, air traffic controllers and an airline's operations center will simultaneously share digital information to optimize routing efficiency and enhance safety by reducing workload and radio frequency congestion. Test flights will be flown on a blend of sustainable fuel, which significantly lowers aviation's environmental footprint. The testing program is expected to last about four weeks before Etihad enters its Boeing 787-10 into service.
