  DoD researchers literally reinvented the wheel with shape-shifting tracks

  By: Kyle Rempfer Wheels are faster on hard surfaces, while a tracked design performs better on soft ground. Rather than pushing a ground combat vehicle through terrain it doesn't perform well on, why not just slap on some shape-shifting wheels? A team from Carnegie Mellon University's National Robotics Engineering Center demonstrated the feasibility of such shape-shifting wheel-track mechanisms for the Defense Department recently. The new technology, dubbed a “reconfigurable wheel-track,” can transition from a round wheel to a triangular track and back again while the vehicle is in motion — allowing for an instant improvement in tactical mobility on shifting terrain. The wheel-track is part of the Defense Advanced Research Projects Agency's Ground X-Vehicle Technologies, or GXV-T, program, which aims to improve mobility, survivability, safety, and effectiveness of future combat vehicles without piling on more armor, according to a June 22 press release. “We're looking at how to enhance survivability by buttoning up the cockpit and augmenting the crew through driver-assistance aids,” said Maj. Amber Walker, the program manager for GXV-T in DARPA's Tactical Technology Office. “For mobility, we've taken a radically different approach by avoiding armor and developing options to move quickly and be agile over all terrain.” The DARPA initiative is looking to build a future in which combat vehicles can traverse up to 95 percent of off-road terrain, including slopes and various elevations. The new wheel-track design is just one of the contract awardees that recently demonstrated advances on a variety of potentially groundbreaking technologies that meet the program's goals. DARPA also showcased a new “multi-mode extreme travel suspension” system that allows for "high-speed travel over rough terrain, while keeping the vehicle upright and minimizing occupant discomfort,” the agency said in its statement. The suspension can move 42 inches upward and 30 inches downward, and keeps itself level on steep grades by adjusting each wheel. Other enhanced mobility designs include an electric in-hub motor built by QinetiQ, which puts motors directly inside the wheels, offering heightened acceleration and maneuverability with optimal torque, traction, power, and speed over rough or smooth terrain. “QinetiQ demonstrated a unique approach, incorporating three gear stages and a complex thermal management design into a system small enough to fit a standard military 20-inch rim,” according to the release. Another new development could impact a vehicle crew's awareness. Most combat vehicles have small windows. This improves the protection offered to troops, but limits their visibility to spot threats and targets. The GXV-T program is looking at sensor technologies to give mechanized troops their eyes back. One design by Honeywell International boasts an enhanced 360-degree awareness suite through virtual windows. The company showed that capability off in a windowless cockpit of an all-terrain vehicle with an opaque canopy, according to the DARPA release. “The 3D near-to-eye goggles, optical head-tracker and wrap-around Active Window Display screens provide real-time, high-resolution views outside the vehicle,” the release reads. “In off-road courses, drivers have completed numerous tests using the system in roughly the same time as drivers in [ATVs] with full visibility.” No fielding date has been announced by DARPA's offices for the new mobility technologies, but the program could help solve many of the ongoing mobility issues troops have experienced in recent conflicts.

  Critics point out holes in Swiss government’s $8.2 billion ‘Air 2030’ plan

  By: Sebastian Sprenger COLOGNE, Germany — The Swiss are choosing sides over how to shepherd an $8.2 billion package of new combat aircraft and air-defense equipment through the country's unique political process. Defence Minister Guy Parmelin favors subjecting the “Air 2030” program to a public referendum, eyed for 2020. If approved, that step could secure the population's thumbs-up for a blank check covering the cost of the entire project while leaving the administration to sort out the details of which planes to buy and how to split the aerial and ground components. This course of action is still preferred, a defense department spokesman told Defense News on Thursday, even though opposition to the plan became increasingly evident as the public feedback period ended Sept. 22. For now, there appears to be support across the major political parties for the main objectives of Air 2030, which aims to replace the country's aging fleet of F-18 and F-5 combat aircraft and install new ground-based weapons against aerial threats. But critics in parliament contend that the risk of a referendum defeat is too high, arguing nothing less than that the very future of the Swiss military is at stake. Depending on which political party is asked, some prefer putting the project out for separate votes for the larger aircraft portion, estimated at roughly $6 billion, and the ground segment. But others want the government to proceed without any referendum at all, arguing that the program — despite its hefty price tag — should be treated like other critical government purchases. The government's strategy of seeking popular approval only for the broad contours of Air 2030 follows the still-fresh memories of a failed attempt to replace the Swiss air-policing fleet. The population in 2014 voted against a measure to buy 22 Saab Gripen planes in a referendum that some analysts said was muddied by questions over the aircraft's specific capabilities and drawbacks. Swiss defense procurement agency Armasuisse on Monday invited bids for the ground-based program segment from the military sales offices of the United States, France and Israel. Those countries' anti-missile systems — Raytheon's Patriot, Eurosam's SAMP/T and Rafael's David's Sling — are expected to go toe-to-toe in a competition. For the aircraft portion, the Swiss in July invited bids from the Airbus Eurofighter, the Dassault Rafale, the Saab Gripen E, the Boeing F/A-18 Super Hornet and the Lockheed Martin F-35A. Armasuisse requested pricing proposals for a fleet of 30 or 40 planes. Meanwhile, government officials will sift through the fresh feedback from Swiss stakeholders — including political parties, regions and trade unions — in the coming months and formulate a measure for parliamentary debate by year's end, defense department spokesman Renato Kalbermatten told Defense News. And while the course of putting the entire investment plan out for a referendum remains the goal, there appears to be a willingness to adjust in case the risk of rejection is deemed to high. “We will put forward the best solution,” Kalbermatten said. https://www.defensenews.com/global/europe/2018/09/28/critics-see-big-holes-in-swiss-governments-82-billion-air-2030-plan
