  The US Army is building zombies. (No, not the brain-eating kind.)

  By: Jen Judson WASHINGTON — The U.S. Army is recycling demilitarized rocket motors and repurposing the materials to make test missiles and it's saving the service money, according to Thomas Webber, director of the Army's Space and Missile Defense Command Technical Center. These test missiles are called “zombies” and save the Army from having to destroy old boosters, giving them a new life, Webber said during the Defense News Space and Missile Defense Symposium Debrief event Aug. 5. The effort started several years ago when the Army's Program Executive Office for Missiles and Space and the Patriot air and missile defense lower-tier product office began running out of targets for tests and spending “a lot” of money to buy more targets, Webber said. The tech center proposed a “significantly cheaper” solution of using recycled motors reaching the end of operational life that would be appropriate for both developmental and operational missile tests, which are accurately representative of ballistic missile threats, he said. Following a demonstration at the end of 2016, the zombies have taken off. “We've been very successful,” Webber said. Since then, the program has expanded, providing targets not only for Patriot testing, but also the Missile Defense Agency and foreign military sales test events. The Army has built seven targets to date. There are three variants: Pathfinder Zombie; the Black Dagger Zombie that adds an additional booster — the Terrier MK70 — for longer ranges; and Sabre, a shorter-range version. A zombie was the target used in a recent critical test showing the Patriot system could be interoperable with the Army's Terminal High Altitude Area Defense system, Webber said. Another target was successfully deployed in a June 25 test at White Sands Missile Range, New Mexico, for a foreign military sales customer. The targets will be used in some of the upcoming tests that will help officials make decisions on the Lower-Tier Air-Defense Sensor, the future radar for the Army's Integrated Air-and-Missile Defense System to replace Patriot, Webber noted. Specifically, a Black Dagger will be used during the IAMD Battle Command System limited-user test coming up next month. “It has been a tremendous boon for us to be able to provide a more affordable, effective target,” Webber said. He added that the Army is saving roughly 50 percent of what it would cost to replace targets simply by buying more. “We can turn these around pretty quickly and support those operational test events,” he said. And it has provided “the capability needed to be able to make sure that we're validating and testing those operational weapon systems with regular and recurring test events,” Webber said. https://www.defensenews.com/land/2020/08/16/the-us-army-is-building-zombies-no-not-the-brain-eating-kind/

  FVL: Bell, Sikorsky-Boeing Split $181M To Finalize FLRAA Designs

  After two years of intensive digital engineering, in 2020 the Army will pick either a Bell tiltrotor or a Sikorsky-Boeing compound helicopter to replace the UH-60 Black Hawk. By SYDNEY J. FREEDBERG JR. WASHINGTON: A Sikorsky-Boeing team won a $97 million award to refine their SB>1 Defiant high-speed helicopter over the next two years, the Army announced today, while Bell Textron won $84 million for its V-280 Valor tiltrotor. The two designs are vying to replace the Reagan-era UH-60 Black Hawk, the Army's workhorse air assault and medevac transport. The difference in amounts purely reflects the different approaches the two teams proposed for what's called Competitive Demonstration & Risk Reduction, Army officials told reporters. It doesn't imply either team has an advantage going into 2022, when the service will choose one design as its Future Long-Range Assault Aircraft (FLRAA), with the first operational units flying in 2030. FLRAA is just part of the flying “ecosystem” of manned and unmanned aircraft that the Army is developing under its Future Vertical Lift Cross Functional Team, which in turn is just one of eight CFTs working on 31 high-priority projects. But FLRAA has been unusually visible, literally, because – as part of a program called the Joint Multi-Role Tech Demonstration – both companies have prototype aircraft actually flying. As we've reported previously, the SB>1 Defiant started flight tests a year later than the V-280 Valor, but Army officials reasserted today they'll have enough test data on both aircraft. “The flight envelope continues to expand for Sikorsky-Boeing, so they're flying a bit more aggressively now than the V-280,” said Brig. Gen. Walter Rugen, head of the FVL CFT. “Towards the end of this fiscal year, maybe August, we're going to see very comparable data on both.” “Flight time is only one of the inputs that goes into a multivariable non-linear calculation,” added the Army's aviation acquisition chief, Program Executive Officer Pat Mason. Not all flight hours are equally valuable, he told reporters, and flight hours alone are not enough. “[It's] what you did in flight, what you've done in modeling and simulation, how you're administering model design, how you [set up] your digital engineering development environment, what you've done in your component test, lab test, SIL [System Integration Lab] test. Taking the totality of those elements into consideration, what we see is a good competition between two vendors.” So while the two aircraft will continue flying to provide more performance data, the lion's share of the work over the next two years will be digital, explained the Army's program manager for FLRAA. “The preponderance of this effort is associated with digital engineering and model-based systems engineering,” Col. David Philips said. That means taking the real-world data from physical tests and rigorously refining every aspect of the design to meet the Army's needs from flight performance, combat survivability, affordability, sustainability, safety and more. The program's reached the phase of design refinement that's traditionally handled by engineers with slide rules on “reams of paper,” Mason explained, but which will now be accomplished in painstakingly precise virtual models and simulations of every aspect of the aircraft. “That is the future of design,” Mason said. “The key is that digital environment.... digital engineering and model-based engineering.” The flight tests of physical aircraft are proving out their novel configurations – designed to achieve high speed and long range that are aerodynamically unattainable for conventional helicopters. But the digital design phase is especially suited for working out the software that's essential to everything from flight controls to navigation to evading incoming anti-aircraft missiles. Rather than have each vendor fit the electronic jigsaw together in their own unique, proprietary way, the Army insists that FLRAA, its sister design the FARA scout, and a whole family of drones all use the same Modular Open Systems Architecture. MOSA is meant to ensure that all the aircraft can easily share data on everything from maintenance diagnostics to enemy targets, and that the Army can easily replace specific components (hence “modular”) using whatever vendor offers the best technology (hence “open”). To ensure different vendors' products plug and play together, Mason said, “we specify what we need in those interfaces, and we flow those out in models.” Those models will include simulations of the aircrafts' physical characteristics, but, since they're software themselves, they can contain the actual prototype code for the Modular Open Systems Architecture. In other words — let's get digital. https://breakingdefense.com/2020/03/fvl-bell-sikorsky-boeing-split-181m-to-finalize-flraa-designs
