  Open source platforms, flexible airframes for new drones

  Kelsey D. Atherton Designing a drone body is about settling on the right compromise. Multirotor drones excel at vertical lift and hover, while fixed wing drones are great at both distance and wide-open spaces. In February, Auterion Government Solutions and Quantum-Systems announced a two-pronged approach to the rotor- or fixed-wing drone market, with a pair of drones that use the same sensor packages and fuselage to operate as either the Scorpion Trirotor or the Vector fixed wing craft. “As we started to develop our tactical UAS Platform, our plan was only to develop a VTOL fixed wing solution (like our Vector),” said Florian Siebel, managing director of Quantum-Systems. “During the development process we decided to build a Tri-Copter Platform as well, as a result of many discussions with law enforcement agencies and Search and Rescue Units.” Adapting the fixed-wing fuselage to the tri-copter attachments means the drone can now operate in narrow spaces and harsh conditions. Scorpion, with the rotors, can fly for about 45 minutes, with a cruising speed of zero to 33 mph. Put the fixed wings back on for Vector, and the flight time is now two hours, with a cruising speed of 33 to 44 mph. The parts snap into place without any need for special tooling, and Auterion recommends the drone for missions in rain or snow. Both platforms share a gimbal EO/IR with 10x optical zoom, 720p EO video, 480p IR video, laser illuminator, IR laser ranger. Common between modes is also a tactical mapping tool using a 21 megapixel Sony UMC R10C camera. For the scorpion, there's also the option of a gimbaled electro-optical camera with a 30x optical zoom. Both drones are designed to fit in rucksacks that a person can carry one at a time. While many features are common across Vector and Scorpion, the plan is not to include both rotors or wings in the same kit. Once a team packs into the field with a drone on its back, that's the mode the drone can be used in. Auterion intends to ship the drones by the fourth quarter of 2020, with preorders available. Designing a drone body is about settling on the right compromise. Vector and Scorpion are built on top of open source code. This includes an operating system capable of programmable autopilot , as well as machine-vision collision prevention and obstacle detection and avoidance. Software for the ground station and cloud data management of the drone are also built on open source code. The Pentagon's Defense Innovation Unit awarded Auterion a $2 million contract last year to work on the PX4 software to help drive compatibility standards in the drone industry. As militaries across the world look to the enterprise sector for capable drones at smaller profile than existing military models, transparency in code and flexibility in airframe could become more widely adopted trends. In the meantime, there is Vector, and there is Scorpion. https://www.c4isrnet.com/unmanned/2020/03/25/open-source-platforms-flexible-airframes-for-new-drones

  Soldiers to get a say in light tank competition

  By: Jen Judson WASHINGTON — Two companies are competing to build the Army's new light tank for Infantry Brigade Combat Teams and, in order to win, their prototypes will be judged by the users themselves. Those tests will be part of an extensive evaluation beginning roughly a year from now, Maj. Gen. Brian Cummings, Army program executive officer for ground combat systems, told Defense News. BAE Systems and General Dynamics Land Systems were chosen in December 2018 to build 12 prototypes each of the Army's future Mobile Protected Firepower vehicle identified in the Army's ground combat vehicle strategy, released in 2015, as much needed capability the service lacked. GDLS will build a vehicle that takes the United Kingdom's AJAX chassis and combines it with an Abrams turret. BAE Systems will bring an M8 Buford Armored Gun System with new capabilities and components. The MPF is going to be critical for the infantry, according to Brig. Gen. Ross Coffman, who is in charge of combat vehicle modernization. “Looking in every war movie ever watched, the infantry has been pinned down and they have a machine gun nest or another enemy vehicle that's preventing them to get their objective,” Coffman said. “It takes an Audie Murphy-like character to go up and sneak around and take it out from the rear.” MPF is going to take care of those impediments to forward progression, he said, and is a “vital piece of equipment for our Army. Right now we are doing that with Humvees and Javelin.” The soldier vehicle assessment will take place at Fort Bragg, North Carolina, and Fort Stewart, Georgia, and will include live-fire tests and operating in IBCT formations, Cummings said. The assessment will not just cover how the vehicles perform operationally, but how they hold up when assessed against warfighting doctrine, organization, training, maintenance in the field, logistics and sustainment. “This will be different, even though we've done it in history,” Cummings said. A team will look at doctrine in terms of having a light tank in the formation as well as having mechanics, fuel and the ability to recover vehicles as part of the operational assessment. “It's important we learn that early on,” in the prototyping process rather than after choosing a winning vehicle, Cummings noted. The Army is now reviewing design maturity of the vehicles and is making sure that everything stays on track to meet the soldier vehicle assessment requirements. These prototypes have to be ready for prime time when they get into an operational environment toward the end of next year, according to Cummings. Cummings also has two groups working with each vendor that are firewalled from one another. Those groups will be working with vendors through the SVA and to eventual down-select to one vehicle around the second or third quarter of fiscal year 2022 to go into production. The prototypes are expected in the third quarter of fiscal 2021. The first units will get MPF by FY25. The Army plans build 26 vehicles initially with an option to build 28 more and retrofit eight prototypes. https://www.defensenews.com/digital-show-dailies/ausa/2019/10/15/soldiers-to-get-a-say-in-light-tank-competition
