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.

By: Jen Judson WASHINGTON — The Army is wading back into an effort to replace the Bradley Infantry Fighting Vehicle with the release of a market survey on Feb. 7, tapping industry for ideas on what a future Optionally Manned Fighting Vehicle (OMFV) might look like. After receiving only one bid in its previous attempt to develop and procure the OMFV and subsequently deciding to cancel the existing solicitation last month, the Army has a new plan to move forward that seeks to avoid some of the pitfalls encountered during its first try. The market survey itself asks companies to weigh in on what affected their decisions to participate, or not, in the previous OMFV competitive effort and how the Army might better engage with industry this time around. Instead of a laundry list of requirements that when paired together became unachievable — especially when delivered over an ambitious fielding goal of 2026 — the Army will be giving industry roughly nine characteristics, each of which will be laid out simply enough to take up just a page-and-a-half including a signature block, Army Futures Command Commander Gen. Mike Murray told a group of reporters at the Pentagon shortly before the release of the survey. The Army had previously laid out requirements such as the need to transport two vehicles in a C-17, for example, which turned out to be a difficult ask to industry within the timeline the Army was pushing. While the list of characteristics did not post with the market survey, Murray said the vehicle will have to protect soldiers, keep pace in a combined arms formation, be able to upgrade over time through open architecture, and be capable of growth without significant weight increases. It also must be lethal, and able to traverse bridges and main supply routes. Additionally, the vehicle should be transportable by rail, air or sea, and crew members have to fit in the back. An on-board training system would also be nice, Murray said, adding that the Army wants to take a look at different options for power and energy sources. Murray also stressed the document outlining the characteristics would change as the Army learned more down the road. Not required of industry will be physical bid samples as it previously requested. Only General Dynamics Land Systems was able to deliver a bid sample, but it did not meet all the requirements the service had laid out. Defense News first broke the news that a Raytheon-Rheinmetall team was unable to get its Lynx combat vehicle to the United States from Germany in time and was subsequently disqualified and that BAE Systems, the incumbent, wouldn't participate in the competition either. The ability to see what was possible from a technology and integration standpoint “was important to us and so I wouldn't say it was a mistake," Murray said of the decision to require a bid. “Did it lead to some problems we had? Maybe. But I would not characterize that as a mistake.” The Army, instead, will take a more measured approach, holding conversations with industry, requesting white papers and then choosing five prime contractor teams to design rough digital prototypes, according to the Army's acquisition chief, Dr. Bruce Jette. The Army plans to involve “soldier touch points” at every stage of the process and give soldiers a chance to heavily evaluate designs along the way, he said. Murray took pains to emphasize that soldiers would be involved in the design process, calling it “soldier-centered design,” which takes a page from other modernization efforts like the Integrated Visual Augmentation System (IVAS) program. And before ever bending any metal, the service will downselect to a group of three contractors that will provide more refined and detailed digital prototypes akin to a critical design review stage. Then the Army will choose two prime contractors to build prototypes that will be heavily tested and demonstrated in order to potentially choose a winner that would move into a manufacturing contract, Jette explained. While the timeline was ambitious in the previous effort and Army modernization goals dictated that it had to stick to schedule over all else, a schedule or even a benchmark for the first unit equipped isn't defined this time around. Murray said the Army will look to early conversations with industry to inform possible schedules based on what is feasible rather than setting an “arbitrary date” right up front. The Army is also planning to look at up to five vendors for major subsystems or components, Jette said. He also noted the service wants to “encourage companies to bring forth technology” that may not want to be a prime contractor, but have capabilities like automated loaders and fire control systems as well as in-cab wireless connectivity. “The barrier to entry is much lower for their investment,” he said. “By going to a digital design, as most do anyway, it makes it much easier for a company to participate as an [Original Equipment Manufacturer] OEM.” https://www.defensenews.com/land/2020/02/07/army-wades-back-into-effort-to-replace-bradley-vehicle/
