    Lockheed, Bell begin forging prototypes to compete for Army’s future armed recon aircraft

    Jen Judson WASHINGTON — Lockheed Martin's Sikorsky and Bell have each begun to forge the aircraft that will compete to become the U.S. Army's Future Armed Reconnaissance Aircraft (FARA) expected to be fielded by 2030. “It's become very real to me,” Brig. Gen. Wally Rugen, who leads the Army's effort to develop future vertical lift aircraft, told Defense News in a recent interview. “We're seeing forgings, castings, transmissions, gear boxes, blades, cockpits, airframes, real tangible things that are already built, already manufactured and going together,” he said. Final designs on the aircraft are due from both Bell and Lockheed in November, according to Rugen. And despite complications across the defense industry due to the coronavirus pandemic, both vendors “see no problem” achieving that original schedule. The Army will take about a month to review those final designs, Rugen said, and then the service will conduct a readiness review with Army senior leaders in mid-December, where the hope is the program will get the final go-ahead. The service is pushing for the prototypes to fly for the first time in the first quarter of fiscal 2023. One major factor in getting those prototypes airborne is whether the Army's Improved Turbine Engine Program (ITEP) engine is ready to drop into the aircraft. The ITEP engine has been developed to replace the engines in UH-60 Black Hawk utility and AH-64 Apache attack helicopters, but will also be FARA's first engine. Key to progress with that is getting the first engine into testing starting in late 2021, Rugen said. “That is our engine and that is our critical path really through the engine,” he said. General Electric, which is building the ITEP engine for the Army, “understands that,” Rugen said. “They've had a lot of friction to fight through and they're fighting through it very well from what I can see,” he added, referring to the impact of the pandemic on the company's progress. While the ITEP engine schedule has not slipped, it has now essentially lost any padding and is aligned with the original schedule, Rugen said. General Electric and the Army had previously found some ways to accelerate the timeline. In addition to ITEP, the Army is also planning on furnishing a gun and a modular effects launcher to both competitors. The 20mm gun has begun firing live rounds and will fire 285,000 rounds “this year,” Rugen said. The modular effects launcher is in the prototyping phase, but Rugen added that, like the 20mm gun, it will fly at Project Convergence 2021 on a FARA surrogate aircraft. Sikorsky has pitched a design based off of its S-97 Raider that it is calling the Raider X. The S-97 has been flying for more than five years. “These flights have produced tremendous data that inform our flight program, help refine the design of Raider X ... and reduce risk for the program,” Jay Macklin, Sikorsky's business development director for FVL, told Defense News. The company began building physical components last year in anticipation of a contract to build a prototype, he said. Sikorsky also has had key suppliers under contract for more than a year. During the flight test period, Sikorsky plans to be “more focused on validation of design versus traditional methods of fly-fix-fly that have been used on many past aircraft across industry,” Macklin said. Bell unveiled its design — the 360 Invictus — for FARA a year ago just ahead of the Association of the U.S. Army's annual conference. Bell has completed multiple design and risk reviews and reports it is on schedule for its build, according to Chris Gehler, vice president and program director of the Invictus program. The company has completed critical design reviews for rotors and drive systems, and the team has been accepting parts at its Amarillo, Texas, facility where it will soon begin to build the aircraft, Gehler told Defense News. https://www.defensenews.com/digital-show-dailies/ausa/2020/10/14/lockheed-bell-begin-forging-prototypes-to-compete-for-armys-future-armed-recon-aircraft/

  • Robots Autonomously Navigate Underground in DARPA Challenge

    Robots Autonomously Navigate Underground in DARPA Challenge

    Whether robots are exploring caves on other planets or disaster areas here on Earth, autonomy enables them to navigate extreme environments without human guidance or access to GPS. The Subterranean Challenge, or SubT, is testing this kind of cutting-edge technology. Sponsored by the Defense Advanced Research Projects Agency (DARPA), the contest concluded its second circuit on Wednesday, Feb. 27. Taking first in the competition was CoSTAR, a 12-robot, 60-person team led by NASA's Jet Propulsion Laboratory (there were also winners declared for a separate, virtual competition). SubT is divided into four circuits spread over three years. With each, teams program their robots to navigate a complex underground course. The first contest, held last August, took place in a mine. For the most recent, called the Urban Circuit, teams raced against one another in an unfinished power plant in Elma, Washington. Each team's robots searched for a set of 20 predetermined objects, earning a point for each find. For the Urban Circuit, CoSTAR earned 16 points; the No. 2 team, with 11 points, was Explorer, led by Carnegie Mellon University. "The goal is to develop software for our robots that lets them decide how to proceed as they face new surprises," said CoSTAR's team lead Ali Agha of JPL. "These robots are highly autonomous and for the most part make decisions without human intervention." CoSTAR, which stands for Collaborative SubTerranean Autonomous Robots, brought machines that can roll, walk or fly, depending on what they encounter. Along the way, the bots have to map the environment and find objects like a warm mannequin that simulates a disaster survivor or a lost cellphone with a Wi-Fi signal. This particular course, which aims to simulate an urban environment, also included a carbon dioxide leak and a warm air vent. Joining the team for the Urban Circuit was a four-legged robot called Spot, which was provided by Boston Dynamics. "One of the two courses we had to run had multiple levels, so it was great that the Boston Dynamics robots were fantastic on stairs," says Joel Burdick, a Caltech professor and JPL research scientist. He is the leader of the Caltech campus section of the CoSTAR team. As the bots explore, they send back video and digital maps to a single human supervisor, who they remained in radio contact with for the first 100 feet (30 meters) or so of the course. They can extend that range by dropping communications nodes, a kind of wireless repeater. Once out of contact, it's up to each robot to decide whether to proceed or backtrack in order to update the team. Each must also rely on fellow robots to access different levels of the course. For example, a wheeled robot might request a quadrupedal one to climb or descend a flight of stairs. "These courses are very, very challenging, and most of the difficulty lies in communicating with the robots after they've gone out of range," Agha said. "That's critical for NASA: We want to send robots into caves on the Moon or Mars, where they have to explore on their own." Mapping caves on the Moon or Mars could identify good shelters for future astronauts. Moreover, if it exists at all, microbial life has a better chance of survival under the surface of Mars or within the icy seas of planetary moons, like Europa, Enceladus and Titan. NASA wants to search for life in these regions, where robots would be frequently out of contact. The next circuit in the Subterranean Challenge will be set in an undisclosed natural cave network this August. A final circuit that blends tunnels, urban environments and natural caves will take place in August of 2021. Teams competing in that final event have the opportunity to win up to $2 million in funding from DARPA. CoSTAR, includes JPL; Caltech, which manages JPL for NASA; MIT; KAIST (Korea Advanced Institute of Science and Technology); Sweden's Lulea University of Technology; and industry partners.
