Customized Pilot Cervical Spine Protection Orthosis DevelopmentF-0080-2024-10765/7/2024
Pilots and crew of rotary-wing aircraft can be exposed to inertial and task position stressors that generate pain. Repeated painful exposures with or without tissue damage are precursors to pain sensitization and chronic pain. Chronic pain leads to reduced operational readiness and long-term medical treatment. This study investigated protection orthosis for unrecoverable effects on the cervical spine by heavy helmets and accessories. A user-customized product has been developed and customization has been intended to be done with multi-body dynamic modeling and testing. Although there are many biomechanical models of the human cervical spine in the literature, their analysis capabilities to perform modal analysis and frequency response analysis are limited. Especially for Rotary-wing applications, models with such capabilities will play an essential role in diagnosing and rehabilitating musculoskeletal disorders and designing engineering devices to prevent and heal cervical spine injuries. Therefore, a detailed head-cervical spine model is developed in which frequency domain analysis is possible. Alternative design solutions have been investigated to support helmets to decrease the load exerted on the neck periphery. Finally, tests have been performed to correlate analysis with a real helicopter environment. At the end of the study, a customizable neck orthosis has been developed and verified with the tests that it reduces the adverse effects of heavy helmets on the cervical spine periphery.

Test Method for Catalytic Carbon Brake Disk OxidationAIR5567A (Current)9/16/2020
The scope of the test method is to provide stakeholders including fluid manufacturers, airport operators, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This simple test is only designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions. It is not possible to set a general acceptance threshold oxidation limit based on this test method because carbon brake stack oxidation is a function of heat sink design and the operating environment.

PTW Passive Safety: Numerical Study of Standard Impact Scenarios with Rider Injury Risk Assessment2020-01-09304/14/2020
Powered two-wheeler (PTW) riders and passengers are among the group of vulnerable road users (VRU). This group uses the road transportation system together with other better-protected users such as passenger cars and truck drivers. The main vulnerability of PTW rider lies in their unequal position during the crash, due to the inability of application of the crashworthiness concept during the PTW vehicle design. This inequality could be somehow mitigated by the design of personal protective equipment (PPE). Mostly the design of the PPE’s is led by the standards which often are obsolete and takes into account only simple drop-tests (ECE 22.05). Those tests did not take into account complicated kinematics of the motorcycle accidents and biomechanics of the human body (the assessment is based only on the linear acceleration of the headform center of gravity). The authors propose a virtual approach for the PTW rider injury risk assessment, which coupled with the pre-impact conditions, could be used for the new PPE protection standards preparation. In this paper, authors want to present a numerical study on the most common PTW impact scenarios, which are described in ISO 13232. The simulations of the accidents were conducted in the VPS numerical environment (PAM-Crash explicit solver). Accidents participants, namely opposite vehicle (OV) modeled by finite element method (FEM) approach, powered two-wheeler (PTW) modeled by multi-body system (MBS) approach, PTW driver represented by hybrid FE-MBS human body model Virthuman and a helmet (modeled by FE approach) were coupled to represent the 7 most common accident scenarios. The helmet is the only PPE enforced by the law, but not in all territories (Afghanistan, Dominica, Guyana, Mexico, Libya, Senegal, USA). Due to the complexity of the OV FE model, there was a necessity of model simplification and revalidation, which also was done in this work. The results of the simulations were examined with special emphasis on realistic representation of real accident kinematics. In each configuration, an injury risk assessment was done on the PTW rider model. The assessment was done based on injury criterion used by the NCAP, UNE 135900 and the LNL criterion. The paper shows that the virtual approach using the Virthuman human body model could be used for the simulation of PTW accidents. The results of this paper could be used for future PPE design.

Production Method for High-Performance PolymerTBMG-361973/1/2020
A method was developed to produce a polymer material called PBO — known commercially as Zylon — that’s used in bulletproof vests and other high-performance fabrics. The new approach could be useful in making PBO products that resist degradation — a problem that has plagued PBO-based materials in the past.
‘Hyper Glue’ Could Be Used for Medical ImplantsTBMG-360152/1/2020
Researchers hope to make everything from protective clothing to medical implants stronger and more corrosion resistant thanks to a newly developed hyper glue formula. The team of chemists and composite materials researchers discovered a broadly applicable method of bonding plastics and synthetic fibers at the molecular level in a procedure called cross-linking. The cross-linking takes effect when the adhesive is exposed to heat or long-wave UV light making strong connections that are both impact-resistant and corrosion-resistant. Even with a minimal amount of cross linking, the materials are tightly bonded.
Threads Detect Gases When Woven into ClothingTBMG-359892/1/2020

Durable Polyimide AerogelsTBMG-3572712/1/2019
Innovators at NASA's Glenn Research Center have developed polyimide aerogel technologies that are 500 times stronger than traditional silica aerogels. These durable polyimide aerogels are highly flexible and foldable in contrast to traditional silica aerogels, which shed dust particles and are notoriously fragile and brittle. Polyimide aerogels possess remarkable strength, flexibility, and moisture resistance and make excellent “wrappable” insulators. No other aerogel possesses the compressive and tensile strength of this organic polyimide aerogel while still retaining its ability to be flexibly folded to contour to whatever shape is needed such as automotive shields, pipeline insulation, and protective clothing.

CONTI SUITS UP19AUTP10_0110/1/2019
A team of young innovators aims to transform a critical piece of safety equipment - and create new business - through collaboration. Few colors shock the human brain into attention more than high-visibility Yellow. “Hi-viz” as it's known in the safety-apparel industry, is an on-the-job requirement for first responders, road workers, tow-truck drivers, linesmen, loggers, couriers, coast guard deck crews - any all-weather vocation for which being seen in low-visibility situations can make the difference between life and death. Included are overnight package-delivery drivers who must sprint across busy city streets - at night, in the fog and rain - to deliver the goods. But hi-viz, even when combined with reflective fabrics, is often not sufficient for wearers to be seen.

U.S. Army Aeromedical Research LaboratoryTBMG-346366/1/2019
In October 1962, the U.S. Army Aeromedical Research Unit was established with a goal of providing specialized medical and physiological support to help close the gap between Army combat aviation needs and human capabilities, and to protect aviators from altitude, climate, noise, acceleration, impact, and other stressors in a growing hostile environment. In 1969, the Army re-designated the unit as the U.S. Army Aeromedical Research Laboratory (USAARL).
Comparison of Two Visual Symbology Sets in Rotary-Wing AircraftF-0075-2019-145605/13/2019
Two sets of visual symbology in conjunction with two display types (helmet mounted and panel mounted) were examined for their usability in maintaining flight performance within a simulated degraded visual environment. Eight rated Army Aviators completed a series of flights using the two symbology sets with each display type. Flight performance data was collected and used to assess performance resulting from symbology and display used. Overall, the assessment found one symbology set to result in better performance across several phases of flight and no significant differences due to display type, although a few interactions between symbol set and display type are noted.

Sound Attenuation of Neoprene Wetsuit Hoods as a Function of Dive Depth and Acoustic Frequency: Hyperbaric Chamber Trials19AERP05_105/1/2019
Data gathered during testing will help develop strategies to protect Navy divers from loud underwater sounds. Naval Submarine Medical Research Laboratory, Groton, Connecticut The U.S. Navy is interested in strategies that divers could employ to protect them from loud underwater sounds. Sonar transmissions and other forms of underwater sound, such as that produced by noisy underwater tools, are an occupational hazard for U.S. Navy divers. At the time this research was conducted, the U.S. Navy guidance for diver exposure to underwater sound accounted for the diver wearing a wetsuit hood but did not account for any changes in the hood's sound attenuation properties with dive depth. Characterizing how the hood's attenuation properties change with depth and frequency is critical to creating appropriate guidance for diver's exposure to underwater sound.

Behavior of Electric Scooter Operators in Naturalistic Environments2019-01-10074/2/2019
The use of electric scooters (e-scooters), which are more generally categorized as motorized scooters, has undergone explosive growth owing to “scooter share” programs in which an e-scooter is rented for a limited period of time. The near-spontaneous ubiquity of e-scooters has prompted government and scooter share companies to address issues partly motivated by concerns related to the inclusion of a large population of e-scooters into vehicular traffic. These issues are influenced by the decisions and behaviors of the scooter operators, who, despite being licensed to drive passenger vehicles, potentially have limited experience operating an e-scooter in the presence of traffic. E-scooters are in a relative unique position where they are small enough to negotiate pedestrian traffic, yet fast enough to travel on roadways. This enables an e-scooter operator to change when and where he rides, e.g., from traveling on a sidewalk to riding in a clear traffic lane in order to avoid a group of pedestrians standing at an intersection. Such changes may catch nearby motorists off-guard, thereby increasing the risk of a collision with the e-scooter. The present observational study assessed e-scooter rider behavior in west Los Angeles, a region with a robust presence of rental e-scooters. The large population, preponderance of e-scooters, and high traffic volumes provide an exemplary area to observe not just how drivers and e-scooter riders adapt to one-another’s presence, but also the increased risk of an interaction between e-scooters with other vehicles and pedestrians. Operator behavior of rented e-scooters is quantified and reviewed according to current regulations, public concerns regarding e-scooters, and behaviors present that may affect an individual’s ability to safely operate an e-scooter in the presence of traffic, including both vehicular and pedestrian.

Rider Stature Influence to Injury Risk in Motorcycle Rear Impact to Car2019-01-14363/25/2019
Road traffic accidents cause one of the highest numbers of severe injuries. Approximately 1.25 million people die each year as a result of road traffic crashes and between 20 and 50 million more people suffer non-fatal injuries, with many incurring a disability. Nearly half of those dying on the roads are so-called vulnerable road users, namely pedestrians, cyclists and two-wheeler riders including motorcyclists. Those vulnerable road users usually undergo complex kinematics and complex loading caused by the other vehicle impact. Virtual human body biomechanical models play an important role to assess the injuries during the impact loading especially for scenarios, where complex dynamical loading is taken into account. An additional benefit of some virtual human models is their scalability, so that they can assess the injury risk for the particular subject taking into account a wide spectrum of the whole population. The presented work shows the motorcycle rider injury risk analysis during the rear motorcycle accident to the car using the virtual approach by the numerical simulation taking into account the variability of the human body. The main aim of the work is to show the injury risk for a varying anthropometry of the motorcycle rider, when a rear impact occurs. Several virtual human body models based on the population variability are concerned. Each virtual human body model is scaled automatically by the previously developed scaling algorithm, coupled to personal protective equipment and sit on the motorcycle. The rear impact to a car is assessed by the numerical simulation. The sensitivity study is processed by evaluating the anthropometry dependent injury risk assessment for the rear impact scenario. The paper contributes to the field of vehicle safety technology by the virtual approach for the assessing the anthropometry dependent injury risk using scalable virtual biomechanical human body models. The personal protective equipment optimization and the injury risk mitigation is consequent result considering the motorcycle impact to the rear end of the car.

Dynamic Spine Brace Characterizes Spine DeformitiesTBMG-336291/1/2019
Spine deformities, such as idiopathic scoliosis and kyphosis (also known as “hunchback”), are characterized by an abnormal curvature in the spine. The children with these spinal deformities are typically advised to wear a brace that fits around the torso and hips to correct the abnormal curve. Bracing has been shown to prevent progression of the abnormal curve and avoid surgery; however, the underlying technology for bracing has not fundamentally changed in 50 years.
Wearable “Microbrewery” Monitors Radiation ExposureTBMG-336261/1/2019
Radiology workers are regularly exposed to low doses of radiation when they obtain patient imagery such as X-rays. While protective gear largely keeps workers within a safe range of radiation exposure, absorbing a little bit is still inevitable. Radiation doses creeping above regulated guidelines pose risk for developing conditions such as cancer, cataracts, skin irritation, or thyroid disease.
Optically Transparent Polyimide AerogelsTBMG-335931/1/2019
Innovators at NASA's Glenn Research Center have expanded their growing portfolio of aerogels to include a new optically transparent polyimide aerogel. Aerogels — low-density, highly porous, ultralight materials derived from gels — can be fabricated to achieve specific desirable traits including various ranges of optical transparency. In the past, high optical clarity was most commonly produced in silica aerogels, which shed dust particles and are notoriously fragile and brittle. In contrast, polyimide aerogels possess remarkable strength and flexibility. They are often used in aerospace applications due to their ability to retain their physical and mechanical properties in thermally and chemically demanding environments.
Energy-Storing Material Folds Onto ItselfTBMG-3322211/1/2018
Eagles can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. New materials have been created that can store energy this way. The materials, called auxetics, behave quite differently from regular materials. Instead of bulging out when squeezed, they collapse in all directions, storing the energy inside.

3D-Printed Device Produces Nanofiber MeshesTBMG-296997/1/2018
Nanofibers are useful for any application that benefits from a high ratio of surface area to volume, such as solar cells that maximize exposure to sunlight, or fuel cell electrodes that catalyze reactions at their surfaces. Nanofibers can also yield materials that are permeable only at very small scales, such as water filters, or that are remarkably tough for their weight, such as body armor. Most such applications depend on fibers with regular diameters. But their commercialization has been hampered by inefficient manufacturing techniques.
