  Hanwha-led team launches Redback vehicle for Australian Army competition

  By: Mike Yeo MELBOURNE, Australia — Hanwha-led Team Redback officially launched its Redback infantry fighting vehicle on Tuesday ahead of delivering three for evaluation trials as part of a risk mitigation effort for the Australian Army. The infantry fighting vehicles are undergoing trials as part of Project Land 400 Phase 3, which is tasked to acquire about 450 tracked IFVs that will replace Australia's fleet of M113AS4 armored personnel carriers. The Redback, which is named after a venomous spider found in Australia, is up against Rheinmetall's Lynx KF41 for the program, which is due to announce a winner in 2022. The risk mitigation effort involves detailed test and evaluation of the vehicles throughout 2021 with the aim of providing objective quality evidence to support a government decision on the preferred platform. Team Redback is the group of companies led by Hanwha Defense Australia, and includes Electro Optic Systems, Elbit Systems and several other Australian companies. Protection for the Redback meets STANAG Level 6 requirements (a NATO standard), and is fitted with a range of active and passive protection systems in addition to survivable seats in the troop compartment, a floating floor to mitigate the effects of mines or improvised explosive devices, and Plasan-made add-on armor. The passive protection system includes Elbit laser warning devices providing all-around coverage, while active protection comes in the form of the Israeli company's Iron Fist active protection system. The Redback is based on South Korea's AS21 infantry fighting vehicle and is fitted with an EOS T2000 turret mounting a Mk44S Bushmaster II 30mm cannon and a 7.62mm coaxially mounted machine gun. An EOS R400 four-axis remote weapons station is also mounted on the turret roof and can be fitted with a range of weapons including machine guns or an automatic grenade launcher. Grant Sanderson, CEO of the Defense Systems division at Electro Optic Systems, told Defense News that the coronavirus pandemic has slowed efforts to integrate the turret, pointing out that having to fly engineers between Australia, Israel and South Korea has been a challenge. However, the lethality testing of the integrated turret is continuing and is expected to culminate in a live-fire demonstration of the turret with Australian optics and systems in August. The Redback is also designed with ride comfort in mind, with rubber tracks and independent suspension in lieu of more common metal running gear and torsion bar suspension. Hanwha added that noise reduction measures has also meant it is possible to conduct conversations in the troop compartment, even when the vehicle is moving. https://www.defensenews.com/industry/2021/01/12/hanwha-led-team-launches-redback-vehicle-for-australian-army-competition/

  Sikorsky ratchets up robotic control of Black Hawk in runup to pilotless flight

  Sikorsky has dialed up the autonomous flight control system on an experimental UH-60A Black Hawk to where a pilot can “set it and forget it” during long surveillance missions, another step toward flying the aircraft remotely from the cabin or from the ground without pilots on board. To date, Sikorsky has put 54.5 flight hours on its optionally piloted vehicle (OPV) flight control system, which is designed as a kit that replaces all legacy mechanical controls in existing aircraft with its MATRIX autonomous fly-by-wire controls. It has also run about 30 hours on the ground in the UH-60A, one of the oldest Black Hawks in the Army's inventory, according to chief test pilot Mark Ward. During the first of MATRIX in a Black Hawk in May, Sikorsky focused on the direct mode control scheme, which means the fly-by-wire controls should fly and respond to pilot input like a conventional UH-60 Black Hawk, Ward said. Technically, the mode is “direct stick-to-head with stability augmentation in the loop.” “Direct mode is supposed to be, more-or-less the service mode or an emergency mode, but we found the aircraft behaved quite well throughout all the speed regimes in that mode,” he said. Sikorsky briefly paused the flight test program to “fine tune” some of the pilot control augmentation modes, “so that when we go to autonomy we're going to have a very mature system that goes from full-spectrum of pilot 100 percent in the loop, to autonomy 100 percent in the loop and everywhere in between,” he said. Test pilots have since ratcheted up computer control of the aircraft and expanded the flight envelope out to 150 knots indicated airspeed. Most interestingly, the test team is beginning to increase the level of flight control augmentation beginning with “direct mode.” In “rate command attitude hold” mode, the fly-by-wire system takes over more control of the aircraft, Ward said. That mode was tested through low-speed hover maneuvers out to 150 knots. “When you put a control input, you're controlling a rate or an attitude change and when you release the control, you're capturing that attitude,” he said. From there, test pilots increased autonomous control of the aircraft to the full authority control scheme, or FACS, in which “rather than commanding a rate, you're actually commanding a parameter, such as airspeed or altitude or heading using the control stick,” Ward said. “To change from one mode to the next is simply a button push away to go from direct to rate command, up to FACS and back down,” he said. “Think of full authority as being an ultra-stable ISR platform that is going to be holding flight parameters for very long periods of time,” he said. “You kind of want to set it and forget it. You're not turning knobs on a flight director. You are actually flying the aircraft with the control stick.” “Rate command is when you kind of want to . . . throw it around a little bit, you want to do some low-and-slow or low-and-fast maneuvering where you're going from stop to stop to complete a mission.” Sikorsky uses the phrase “optimally piloted vehicle” as well as “optionally piloted vehicle” when discussing OPV and MATRIX because the ultimate goal is to develop a system that can act as an autonomous co-pilot quietly but constantly aiding human operators during specific missions. The OPV kit is tailored to the UH-60, but is retrofittable onto the Army's entire helicopter fleet and Sikorsky's commercial S-92 and S-97 rotorcraft, according to Igor Cherepinsky, the company's director of autonomy. Sometime in 2020, Sikorsky will demonstrate that the system can be remotely piloted from both inside and outside the aircraft, he said. “We will show the world this system is capable of being operated from the ground,” he said. Sikorsky continues to demonstrate MATRIX on a modified S-76B called the Sikorsky Autonomy Research Aircraft (SARA). The aircraft, which has been in test since 2013, has more than 300 hours of autonomous flight. The company announced in March that its S-92 helicopter fleet update will include the introduction of phase one MATRIX technology, which will allow for autonomous landing. The U.S. Army has plans to outfit a UH-60M with the system but is about six months behind Sikorsky's OPV test program. “Our vision is, obviously, not to replace the pilots, but to augment the pilots,” Cherepinsky said. “Once we field the technology, we never want to see another controlled flight into terrain or degraded visual environment issue accident ever happen with any of our aircraft.” https://www.verticalmag.com/news/sikorsky-ratchets-up-robotic-control-of-black-hawk-in-runup-to-pilotless-flight/
