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.

Pentagon AI team sets sights on information warfare
Mark Pomerleau About two years after it was created, the Pentagon's artificial intelligence center is setting its sights on new projects, including one on joint information warfare. This initiative seeks to deliver an information advantage to the Department of Defense in two ways. The first is improving the DoD's ability to integrate commercial and government AI solutions. The second is improving the standardization of foundational DoD data needed to field high-performing AI-enabled capabilities to support operations in the information environment, said Lt. Cmdr. Arlo Abrahamson, a spokesman for the Joint Artificial Intelligence Center. Nand Mulchandani, the JAIC's acting director, told reporters in early July that this initiative also includes cyber operations — both broad defensive and offensive measures for use by U.S. Cyber Command. The DoD is discovering that it needs ways to process, analyze and act upon the vast amounts of data it receives. “As we look at the ability to influence and shape in this environment, we're going to have to have artificial intelligence and machine-learning tools, specifically for information ops that hit a very broad portfolio,” Gen. Richard Clarke, commander of Special Operations Command, said at the Special Operations Forces Industry Conference in May. “We're going to have to understand how the adversary is thinking, how the population is thinking, and work in these spaces in time of relevance. If you're not at speed, you won't be relevant. “To make sure the U.S. message and our allies' and partner message is being heard and it's resonating. What we need is adapting data tech that will actually work in this space and we can use it for our organization.” A program in support of network incident detection, called MADHAT — or Multidimensional Anomaly Detection fusing HPC, Analytics, and Tensors — is helping the JAIC develop an information warfare capability. The program allows for the exploration of network data as a way of enabling more effective detection of nuanced adversarial threats, Abrahamson said. MADHAT has already been deployed, he added, and analysts working on the High Performance Computing Modernization Program are being trained on the tool for operational use. This program accelerates technology development and transitions it into defense capabilities through the application of high-performance computing. Mulchandani also told reporters that other information warfare-related efforts include using natural language processing, which involve processing and analyzing text. “NLP and speech-to-text is actually a fairly mature AI technology that can be deployed in production. And that actually is going to be used in reducing information overload,” he said. “So being able to scan vast quantities of open-source information and bring the sort of nuggets and important stuff on the NLPs.” https://www.c4isrnet.com/smr/information-warfare/2020/07/22/pentagon-ai-team-sets-sights-on-information-warfare/

Is Germany’s Puma combat vehicle still tickling the US Army’s interest?
By: Sebastian Sprenger COLOGNE, Germany — German and U.S. military officials had planned, then canceled, a demonstration this week of the Bundeswehr's Puma infantry fighting vehicle, as the U.S. Army surveys candidates for its Next-Generation Combat Vehicle program. A German Army spokesman confirmed that an event had been scheduled at the Munster tank-training area for Jeffrey White, a deputy to U.S. Army acquisition chief Bruce Jette. White ended up canceling because of a scheduling conflict, the spokesman told Defense News. Officials on both sides of the Atlantic were tight-lipped about the details of the planned visit and whether another date is being explored. It is also unclear which country initiated the contact, though the government interested in another's hardware would typically lodge the request for a demonstration. The apparent curiosity by the U.S. Army in the Puma evokes memories from 2010 and 2011, when the German vehicle, still largely in the development stage at the time, was a contender for the now-defunct Ground Combat Vehicle program. Boeing and SAIC, along with the German manufacturing consortium of Rheinmetall Defence and Krauss-Maffei Wegmann, had pitched a modified version of the vehicle for the U.S. Army. Contenders for the new Army vehicle program, NGCV, are still getting into position to pounce on a request for proposals. Rheinmetall this time has teamed with Raytheon to offer the Lynx vehicle, unveiled last June at the Eurosatory trade show in Paris. News that the Puma is on the Army's radar brings up the question of how Rheinmetall, a co-developer of the vehicle, would proceed if the Americans were to invite the Puma to join the field of contenders. Another unknown is how Rheinmetall's stated desire to acquire Krauss-Maffei Wegmann is going play out. In any event, it remains to be seen how a German tank design will fare in the race for a high-profile U.S. defense program in the age of President Donald Trump's sour attitude toward Berlin. Trump has repeatedly berated Germany about what he considers lackluster defense spending, and he has threatened to impose tariffs on German cars in retaliation for what he deems unfair trade practices.
