“The cooperation between government and industry has been a model of how a complex development program can be completed on an expedited schedule, within budget,” said Steve Pruitt, DTS President and CEO. “Starting from a concept technical data package in early 2015 to delivery of four WIAMan Gen 1 manikins in less than three years is a remarkable achievement.”Pruitt said WIAMan will significantly increase the Army’s capability to assess probably of injury to warfighters in a wide range of underbody blast events—saving lives and reducing injuries by helping the Army and industry to design vehicles that best protect them. According to Hughes, the WIAMan package is a key delivery to the material developer for the continued development and production of WIAMan manikins to support the upcoming armored multi-purpose vehicle under-body blast testing in fiscal 2020.“Maintaining our technological advantage in warfare is found in dogged scientific advancements and decisive programs that are steadfast in its pursuit,” said Col.Scott McIntosh, PEO STRI Joint Project Manager Medical Modeling and Simulation.“None are more crucial than those that underpin the survivability of our warfighters.”He said the collaborative work between the WIAMan Engineering Office and JPM MMS embodies this determination to save lives.

“Our two offices’ shared commitment to the program’s purpose combined with an innovative strategy with our industry partners has provided the DOD a cutting-edge test capability that is irreplaceable,”McIntosh said.“Our work illustrates that when the entire process is agreeably focused on the problem set, challenges can be quickly surmounted. Our work will be used for decades to support force wide modernization efforts and evaluate threats to our service members.”The formal transition of the management of the manikin from ARL to PEO STRI culminated in a technology readiness level 6 live-fire test demonstration held at APGJune 13.Army S&T laboratories will continue to execute additional critical elements of the effort, to include ongoing biomechanical research and development of a virtual WIAMan finite element model.

DTS & U.S. Army Celebrate WIAMan Test Lab

DTS & U.S. Army Celebrate WIAMan Test Lab

Seal Beach, CA (February 2017) – Nearly 100 DTS employees and several key U.S. Army personnel gathered for the official ribbon-cutting ceremony at the new WIAMan ATD Lab located inside DTS headquarters in Seal Beach, California. The new lab is being used exclusively to support the design, development and testing of the first blast test dummy, officially called the Warrior Injury Assessment Manikin (WIAMan). DTS is the Prime Contractor to the U.S. Army for the WIAMan project, which is the first anthropomorphic test device (ATD) designed specifically to withstand underbody blasts (like IEDs). The goal of all WIAMAN testing is to advance soldier protection and improve military vehicle designs.

The new 3,000+ sq. ft. lab is furnished with state-of-the-art test equipment including an 11-foot drop tower used to simulate the vertical impact experienced by an occupant in a vehicle blast. A 5-point harness secures WIAMan in the drop tower seat while a 200g pulse simulates blast forces. Load cells in the seat measure five different load paths through the pelvis and femur to quantify potential spine and lower extremity injuries. A linear impactor performs iterative testing on lower leg and pelvis components, accelerating a 20kg impact mass to a velocity of 20 meters/sec. Analyzing gross motor movement in slow motion helps engineers better understand the forces soldiers experience in the field, so multiple high speed cameras capture the action at over 100,000 frames/second.

“The program provides a state-of-art test capability to assess potential skeletal injuries of Soldiers exposed to under-body blast,” said Fred Hughes, director of the WIAMan Engineering Office. “The manikin’s sophisticated biofidelity and robust sensor design provides an unmatched level of accuracy determining the potential effects of blast on Soldiers in new vehicle systems. The WIAMan effort is an example of outstanding collaboration among academia, industry, and the government.”

The WIAMan project is especially important because no human surrogate for blast testing exists today. Automotive crash test dummies have been used in the past, but they are built to withstand frontal and side impacts, not the vertical acceleration of an under-body blast. The multi-year project includes not only building the new ATD, but also a next generation in-dummy sensing and data acquisition solution that goes inside the dummy.

To measure potential skeletal injuries, WIAMan currently uses 146 channels of embedded data acquisition and sensors, but is designed to support up to 180 channels. The self-contained miniature data acquisition systems are distributed throughout the test manikin and include internal power and a variety of sensors. The data collected includes six degree of freedom of forces, moments, accelerations and angular velocities from sensors located along the pelvis, spine, tibia and foot/heal. The data WIAMan will measure has far reaching, life-saving implications not only in the development of safer military vehicles and tactical gear, but to families around the world.

DTS Data Recorders Help NASA Assess Splashdown Impact on Orion Crew

DTS Data Recorders Help NASA Assess Splashdown Impact on Orion Crew

DTS OnBoard NASA Orion Capsule

Seal Beach, CA (Sept. 2016) – Engineers at NASA’s Langley Research Center in Hampton, Virginia, will conduct nine water-impact drop tests to evaluate the Orion spacecraft and crew safety when they return from deep-space missions and touch down on Earth’s surface. Onboard will be two test dummies wired up to Diversified Technical System (DTS) data acquisition systems that will ride along to collect critical test data as NASA prepares Orion for its next mission, Exploration Mission-1. During Exploration Mission-1, the uncrewed Orion spacecraft will launch atop the Space Launch System (SLS) rocket, travel more than 40,000 miles beyond the moon and return at speeds up to 25,000 mph.

Water-impact testing is one of many steps required to ensure Orion will meet the demands of sending humans to deep space for the first time and in the future on the journey to Mars, which is why extensive testing is so critical. Engineers at Langley will mimic various scenarios by dropping a mockup of Orion, coupled with the heat shield from the spacecraft’s first flight, into Langley’s 20-foot-deep Hydro Impact Basin.

This will help NASA evaluate how the spacecraft may behave when landing under its parachutes in different wind conditions and wave heights. Langley has already conducted dozens of splash tests with DTS data recorders inside a less sophisticated capsule mockup, but this is the first time it will assess the higher fidelity Orion ground test article. Unlike many data recorders, DTS systems are so small and lightweight that they fit on-board and run autonomously to collect both structural and crew safety data.

“We are excited about this testing because we’ll have suited-up test dummies inside the capsule,” said Ellen Carpenter, Langley project manager. “Including test dummies will help NASA ensure the crew is protected from injury during splashdown in future missions.”

“These test dummies are the same type of test dummies that are used in the automotive industry for front collisions,” said Rick Ybarra, test engineer at NASA’s Johnson Space Flight Center.

Each dummy was lifted and then manually installed into the interior of the capsule. Prior to installation, engineers placed tiny sensors inside the test dummies, which will be used to help NASA understand the loads the crew could experience when returning from deep space destinations.

Before testing begins, engineers will apply a waterproof coat to the capsule and complete final sensor checks with a DTS data acquisition system. The capsule itself is wired with sensors that allow engineers to collect data during the water-impact testing.

“Preliminary work is key to a successful drop,” Carpenter explained. “It allows the sensors to be verified ahead of time, so that the most accurate test data can be acquired.”

For over 15 years, NASA has used DTS data acquisition systems to capture critical test data on helicopter hard landings, test Emergency Locator Transmitters (ELTs), and even onboard the LDSD-low density supersonic decelerator in the outer stratosphere. Providing accurate test data prior to real-life missions is an important part of research for understanding crash dynamics and improving occupant safety in any arena.
