  The Flying Car Of the Future Looks to Flying Cars of the Past

  The Air Force is close to testing an experimental vertical takeoff prototype under its new program. The first contract in the U.S. Air Force's bid to acquire flying cars has gone to a company whose design harks back to a pioneer in the field. California-based Sabrewing Aircraft Company received a $3.25 million Phase II Small Business Innovative Research earlier this month to test its Rhaegal-B, a four-rotor craft that the company says can carry up to 5,400 pounds up to 200 knots some 1,000 nautical miles. With its four electric rotors, two on either side of the aircraft, the 60-foot Rhaegal-B somewhat resembles the M400X Skycar from Paul Moller. Moller is, in many ways, the Nikola Tesla of the flying car field. In the early 2000s, the Moller International Skycar became the first non-helicopter vertical takeoff and landing aircraft to actually get off the ground. The four motors would lift the car up and then swivel to propel it forward, like a V-22 Osprey. Even though the design worked, it never made it into showrooms. “For the engine, the most critical element is power,” Moller told The Futurist magazine in 2008. “Once you reduce the diameter of the propulsion system [making the propellor smaller] you go from a helicopter to a fan system. So you're moving less air, and the less air you move, the more power it takes to generate a certain kind of thrust. If I took a helicopter and made it one-half the diameter, I would have to immediately add 60% more power. I halve the diameter again, I have to add 60% more power, again. The M400 Skycar has over 1,000 horsepower.” Given the high cost to power it, the M400 Skycar was impractical for most locations outside of the Middle East, where oil sheiks would use them to traverse wide distances, Moller said at the time. Sabrewing CEO Ed De Reyes, who once worked for Moller, said his former boss was restricted by the engines of his time. The best-suited for the purpose were Wankel rotor engines, and internal combustion engines, which offered high speeds but limited torque. The electric motors that have arrived in recent years are far more promising: smaller, lighter, yet capable of producing more torque than an internal combustion engine. The Rhaegal-B design is highly but not fully autonomous, De Reyes said. A controller will command it from a ground station, but with the sort of low-effort, push-button interface you would encounter on a Northrop Grumman Global Hawk, rather than the more hands-on piloting needed for General Atomics MQ-9 Reapers. Something else that's come a long way since the early 2000s is the ability to detect and avoid objects in mid-air. Ssense-and-avoidance systems are a major stepping stone to more widespread use of drones in U.S. civilian airspace. A lot of drone manufacturers are hoping for the FAA's blessing for their versions. The Rhaegal-B combines radar and nine other sensors to give the aircraft a picture of the environment around it. It can take evasive action without any human control. (In fact, humans can't override it to accidentally steer the vehicle into something else.) If communication is cut off, it can continue to its destination with no additional imput from the ground operator. The appeal for the Air Force has to do with versatility and even detectability. During a webcast on Monday, Air Force Col. Pete White, with Air Force Warfighting Integrating Capability, said that traditional helicopters are noisy compared new vertical-lift aircraft. Thanks, in part, to the new electric motors. “Within feet of an enemy, they can't hear you,” He said that new, nimble electric air vehicles that could take off and land without a runway could help the military “maneuver around the battlefield at a pace that would be impossible today” The Air Force says it wants flying cars to evacuate wounded soldiers from the battlefield, among other missions. That means that they could be operating under fire. De Reyes says the military version of the aircraft has a Kevlar coating to protect it from small ballistics and can operate even when one of the motors is damaged. Air Force officials have also said that they are looking to fund and support U.S. flying-car companies, lest they migrate to China or accept lots of foreign investment. De Reyes says he's often approached by Chinese investors looking to gain a foothold in his company and other entrepreneurs in this space are as well. Sabrewing will test the Rhaegal-B at the Air Force's Edwards Air Force Base, hoping to meet safety requirements that will clear it for more military work and perhaps even commercial use. A June flight demonstration with its prototype has been postponed due to travel restrictions https://www.defenseone.com/technology/2020/04/flying-car-future-looks-flying-cars-past/164995

  DISA opens a new operations floor in Utah to boost resiliency

  By: Daniel Cebul WASHINGTON — The Defense Information Systems Agency (DISA) has opened a second operations watch floor to help operate and secure global information-sharing and command and control capabilities, according to a Sept. 12 press release from the agency. The organization opened the new floor July 15 at Hill Air Force Base in Utah. The center is now known as DISA Global West. The original operations watch floor, DISA Global Operations Command, headquartered at Scott AFB, Illinois will now be known at DISA Global East. Opening a second watch floor improves the survivability and redundancy of global network operations, the DISA statement said, and allows for what's described as 24/7 “Active-Active” operations. “Active-Active” means that DISA is continuously available to provide operational and security capabilities, even if one of the two operation centers goes down. This added layer of redundancy is viewed as critical in an increasingly hostile cyber environment. “In a world where our cyber adversaries are becoming more and more sophisticated in their abilities to infiltrate networks and interfere with services, Active-Active operations allows DISA Global to reduce continuity risks and make the Defense Information Systems Network and DISA services more agile and responsive,” said Laura Williams, the agency's Active-Active program manager. While dividing the work force between locations introduces new difficulties to operations, the agency is confident the move will improve resiliency without compromising capability. “It's always a challenge when you have a geographically separated work force,” said Army Col. Lisa Whittaker, DISA Global commander said in the release. “But we are a tremendous team coming together for this effort. The teammates that work at DISA Global West are closely integrated with those at DISA Global East. They work in the same divisions, have the same leadership, and use the same tools, techniques, tactics, and procedures on a daily basis.” One reason teammates are able to stay on the same page despite being over 1,300 miles apart is the agency's use of an Enterprise Virtual Watch Desk, which provides organizations across the agency a common picture of the operational network. https://www.c4isrnet.com/disa/2018/09/12/disa-opens-a-new-operations-watch-floor-in-utah-to-boost-resiliency

  SOCOM seeking technologies for war in a post-cyberpunk era

  By: Kelsey Atherton The great trick of computers is that they enable people to be more than human. In a new request for information, the United States Special Operations Command is looking for a range of computer and computer-enabled technologies, all designed to make Special Operators function in some way more than human. These technologies range from sensors to nano-drones to biomedical performance enhancements. Taken together, the list of desired capabilities is a preview of what may be possible in the near-future to shape the intimate fights on the edges of wars. Miniature robot scouts, hyper-aware data collection and monitoring riding along low-bandwidth nodes, tailorable hyperspectral imaging sensors, biometric tracking resistance, and go-pills without adverse effects are all on asking, and that's just a handful of the dozens of capabilities sought. The full request for information is available online. To parse through it, here are some of the standout categories. Robots, blood-transporting robots How many pounds of blood is a reasonable amount of blood for a robot to carry? Ten pounds, answers the SOCOM request. Specifically, SOCOM is looking for an unmanned aerial blood delivery system that can do vertical takeoff and landing (VTOL), or at least operate without a runway. The 10 pound requirement is a minimum, and roughly approximate to the amount of blood in a person weighing 150 pounds. In order for the blood to be useful, it has to be kept between 35-46 degrees Fahrenheit, ideally through passive means, all the way from loading through transit, delivery, and unloading. That unloading should “minimize shock to the payload for any proposed delivery concept,” because again, this is about making a robot that can deliver blood in a useful and life-saving state. Blood transport drones already exist, and have safely demonstrated blood transport in small amounts and over modest distances. SOCOM wants a blood drone that can transport its cargo over 100 miles and back, while staying in contact and control of human operators. That's an ambitious ask, and it's one of just five named categories of drone technology sought by SOCOM. Another is a platform-agnostic desire for an expeditionary ISR platform, which can operate as individuals, in pairs, or in meshed swarms. These drones will have modular payloads, carry at least two sensors, and require minimum logistics support. One asked-for way to sustain these drones is by “alternative power through environment,” like directly sipping power from power lines or incorporating a way to charge off renewable energy. The other three categories of drone are ambitious, though in more familiar terms. There's a listing for a Nano VTOL drone, with a takeoff weight of 2.6 ounces that can fly autonomously inside and avoid collisions, with a human monitoring but not directly piloting the drone. Ten times the size is the Micro VTOL drone, at about 1.6 pounds, capability of all-weather an autonomous flight, and able to operate both without GPS and in caves. The biggest non-blood-carrying drone SOCOM is looking for is a hand-launched or fixed-wing VTOL vehicle that can be recovered without special equipment, will weigh no more than 7.8 pounds, and can fly for at least 90 minutes at sea level. These drones are familiar machines, mostly, even if some of the payloads are a little unusual. Sensors in a robot are common enough. SOCOM is also looking for a way to increase the sensors carried and used by a person on foot. Hyper-sensors Collecting information is nothing without processing it into a useful form, and this SOCOM RFI seeks information on both. While the specific means are not detailed, there's a desire for “edge computing” to “derive useful information at the point of collection through sensor fusion and forwards processing without reliance on high bandwidth, long haul communications.” That likely means computers and AI already in the field and embedded in equipment carried by the special operations forces. Making that information intelligible is one task a Heads Up Display (HUD), but SOCOM is also open to audio cues and haptic feedback, among other means, for relaying processed information in a useful and immediate form. Collecting that information will be a new suite of Intelligence, Surveillance, and Reconnaissance (ISR) sensors, designed with the limitations and hard conditions of present and future special operations missions in mind. That means working without “owning the air domain,” a break from decades of assumptions for conventional and counter-insurgent warfare, but a break that acknowledges the likely presence of cheap drones on all sides of future battles. These sensors will include visual spectrum, infrared, hyper-spectral imaging, LIDAR, electronic warfare, can operate autonomously and be mounted on drones or scattered on the ground to work and transmit data remotely. For good measure, SOCOM is also asking for technologies that would allow drones to work as something like a universal translator even in denied connectivity environments. With linguistic expertise, regional dialects, demographic information and cultural sensitivities programmed in, the drones will do the fraught social massaging around war. If there is anything that will convince a local population about the right intentions of the people presently fighting nearby, it's a robot that's hip to the local slang. More than human All this collecting and transmitting information is likely to produce a host of signals, so SOCOM is also looking for technologies that “help avoid physical detection by acoustic, thermal, radar, visual, optical, electromagnetic, virtual, and near infrared means.” Finding a way to remain discreet in an information rich environment is a challenge for everyone in society today, one tacitly acknowledged by an ask for a technology to “help manage digital presence within the realm of social media.” (Step 1 for that is probably not using a jogging app with geolocation turned on.) Biometric technologies (think: facial recognition, etc) are often seen as a tool of the powerful, wielded by governments against vulnerable populations. While they certainly can be that, they can also pose a challenge to individuals in the employ of one military trying to evade the sensors used by another. To that end, SOCOM is looking for technologies that provide resistance to biometric tracking. (While it's not specified, Juggalo-style face paint might work for this exact purpose). Finally, once a special operator has evaded detection, used the sensors on hand, and has an adequate amount of robot-delivered blood to keep going, there is an interest in human performance and biomedical enhancements. These include drugs and biologics that can enhance cognitive performance, increase “peak performance sustainability, including increased endurance, strength, energy, agility, and enhanced senses” and a whole other wish list of capabilities that officers from time immemorial have demanded of the people under their command. Most promising, perhaps, is the ask for “medical sensors and devices that provide vital sign awareness and send alerts,” and “austere trauma treatment,” both of which don't require transformative properties in the people using them. Science fan-fiction It's too early to say how many of the asks in this RFI are realistic, though some are already delivered technologies and others certainly seem near-future plausible. More importantly, the request as a gestalt whole suggests a desire for people that are more than human, and capable of performing everything asked of them in remote battlefields, far from home. As the United States approaches its 17th continuous year of war abroad, asking that science deliver what science fiction promised feels at least as plausible as imagining a future where deployments abroad are scaled back. https://www.c4isrnet.com/unmanned/2018/08/28/socom-seeking-technologies-for-war-in-a-post-cyberpunk-era
