1 Warrior Injury Assessment Manikin (WIAMan) Overview Frederick Hughes, Director U.S. Army Research Laboratory To: International Test and Evaluation Association Date: Mike Landers, Assistant Program Manager Program Executive Officer for Simulation, Training and Instrumentation

2 Why WIAMan? WIAMan is the world's first test manikin that is purpose-built for military use in under-body blast (UBB) testing of ground vehicles in LFT&E Strategic Readiness Future Force Benefits include: Soldiers and People Improving soldier survivability and quality of life when subjected to the effects of UBB Improving the protection of ground vehicle systems Evaluating the effects of UBB on mission-critical tasks Quantifying the risk to the Warfighter and identifying tradeoffs during vehicle design 2

3 Program Milestones Program is on schedule and budget Jan 2016: WIAMan TCRD signed / Approved by DOT&E 4QFY19: WIAMan Final VV&A 3QFY19: Delivery of 10 Fieldable Prototypes 3QFY18: Transition of TRL 6 Hardware FY17: WIAMan Gen 1 Injury Testing June 2017: WIAMan Gen 1 ATDs Delivered 1QFY16: RMD700A1 established WIAMan acquisition funding 1Q/3QFY18: AMPV SL UBB Test Events 4QFY20: AMPV FUSL UBB Test Events Sep 2015: ASA(ALT) directs PEO STRI to adopt program of record path Dec 2014: DASA-RT initiates discussions with PEO STRI on WIAMan Feb 2013: WIAMan Project Office (ARL) established Jan 2013: Johns Hopkins University APL leads biomechanics testing Jan 2011: RMD 700 provides 6.2/6.3 funds for WIAMan research and engineering efforts Q1FY11: RMD700 established Army S&T and DHP funding for WIAMan Sep 2010: DOT&E Issue Paper #1: Improvements in Occupant Injury Assessments to Support Ground Vehicle Under Body-Blast LFT&E serves as catalyst for WIAMan effort 3

4 DOT&E Capability Gap DOT&E Issue Papers and RMD700 were based on creating a DoD capability for UBB injury risk assessment that is equivalent to that used by DOT Current capability based on Hybrid III is inadequate for determining the risk of skeletal injury to vehicle-mounted Soldiers subjected to UBB threats The HIII s lack of injury resolution and biofidelity does not support requirements development, system design, vulnerability evaluation, or the modeling and simulation of UBB events. - Dr. J Michael Gilmore, DOT&E Issue Paper, 2013 Army commitment to DOT&E as presented at inaugural meeting of WIAMan SSG in Feb 2011 Create a new military Anthropomorphic Test Device based system for under-body blast injury assessment for Title 10 LFT&E The HIII s verified lack of injury resolution and biofidelity in the UBB environment makes it inadequate to assess injuries in the UBB loading regime. - Dr. J Michael Gilmore, DOT&E Issue,

5 Requirements Snapshot Test Capability Requirements Document (TCRD) Reflects the Department of Transportation s standard for developing a valid ATD-based injury assessment capability Signed by CG ATEC and CG RDECOM; approved by DOT&E in Jan KPP Description #1: Biofidelity WIAMan shall exhibit human-like motion and load transfer when subjected to UBB loading #2: Data Collection WIAMan shall measure and record data that correlate to UBB-related injuries #3: Injury Assessment The relationship between WIAMan response and probability of injury shall be understood #4: Operational Readiness WIAMan shall be available to support multiple concurrent LFT&E UBB vehicle tests 5

6 Governance Regular engagement with DoD and Army stakeholders through Senior Steering Group (SSG) action officers Biweekly council of colonels meetings Program management and technical reviews ASA(ALT) directs PEO STRI to adopt nontraditional, rapid system acquisition with DOT&E sponsorship MOA signed by CG, RDECOM and PEO STRI in Dec. 15 MOA delineates S&T and material developer responsibilities PEO STRI is fully integrated into S&T program activities (technical/schedule) Transition TRL 6 WIAMan system to PEO STRI for material development/procurement (FY18) Mature injury assessment capability through ongoing biomechanics research (FY 17-FY 20) Requirements - OSD-DOT&E - ATEC - RDECOM SSG Acquisition and Sustainment - PEO STRI - ATEC - RDECOM Resources - Army EE PEG - Defense Health - Army S&T - OSD-DOT&E 6

10 Hybrid III vs. WIAMan Gen 1 Hybrid III WIAMan Gen 1 1. Design based on 50 th percentile 1970s male citizen 2. Poor durability compromises reproducibility, repeat testing, and total lifecycle costs 3. Lack of on-board data acquisition; increases set-up times and requires harness 44 miles of cable 4. Legs have no biofidelity or sensors in foot/ankle 5. Rigid design of spine prevents assessment of spinal injury 6. Pelvis does not reproduce human response, offering no relevant instrumentation for injury prediction 1. Design based on today s Warfighter in a seated posture 2. Excellent durability to ensure repeatable injury prediction and reduced lifecycle cost 3. On-board data acquisition to reduce set-up times and eliminate cabling 1 mile of cable 4. Fully instrumented lower extremities for high-fidelity UBBcentric injury prediction 5. Spine curvature allows for improved acceleration response and spinal injury assessment 6. Anatomically accurate pelvis with full instrumentation for pelvic injury prediction 10
