US warfighter safety could be significantly improved by providing an ability to quickly and accurately assess the acoustic impact of rotorcraft operations in the field and reduce the likelihood of detection. Current mission planning tools are empirical in nature, limited to operating conditions for which flight test data exists and challenged in predicting the acoustic impact of maneuvering flight ...

Vascularized composite allotransplantation (VCA) is a surgical approach for the clinical management of non-salvagable injuries. Tissue rejection is a major issue for patients receiving VCA. Tacrolimus is the most common immunosuppressant employed to minim

The nature of complex combat operations must now include adversaries that have peer-level capabilities, such as the ability to locate friendly troops by their transmissions and jam their radios so they can’t call for help, setting them up for attack. However, critical to all combat scenarios, regardless of adversary capability levels, is the need to command, control, communicate and exchange inf ...

Current soldier Individual Water Treatment Devices (IWTD’s) are limited to use with freshwater sources since they lack desalination capabilities. State of the art desalination technologies such as reverse osmosis are too energy intensive and heavy for individual soldier applications. Lynntech has developed a desalination battery that removes salts from feed water as it discharges which eliminate ...

Existing wired and wireless communication systems are simplex, also called half-duplex. The transceiver nodes today either transmit or receive at a given time. Typically, a Frequency Division Duplex (FDD) system is used by radios to transmit and receive at the same time but at different frequencies. GenXComm has developed the world’s first wide-band, small-form-factor single frequency simultaneo ...

To meet the demands of topic A19-009, the MaXentric team proposes the MAESTRO (Millimeter-wave Amplifier under Efficient Switching-mode and Time-multiplexing Operations), which provides a new concept of a power amplifier in millimeter-wave frequency band for commercial and military communication and electronic warfare applications. Using time-multiplexing technique and switching-mode amplifier, hi ...

Dense Urban Environments (DUE) are characterized by large concentrated populations that tend to cluster into groups networked together by common interests and needs. Populations cluster along political, social, cultural, ethnic, economic and other social lines. Networks among these groups, formed along lines of shared characteristics, are often in friction with one another as they contend over sca ...

A major innovative thrust in Army tactical operations is routine use of small Group 1 UAS for surveillance and sensing missions. However, for effective and stealthy use of such assets, low acoustic signature is critical. At present, capabilities for designing such vehicles for minimum noise is extremely limited, especially when combined with the challenge of designing to meet critical mission requ ...

Rotorcraft, both civilian and military, suffer from higher operating costs relative to their fixed-wing brethren due to cyclical loading that limits the useful lifetime of key structural components. Important recent advances in aeromechanics prediction capabilities, coupled with enhanced modeling of fatigue growth on life-limited parts, now allows development of a methodology both to predict real- ...

The objectives of this SBIR include the development of a modeling framework to predict mechanical properties of as-manufactured AM parts accounting for microstructure. The final product will (1) accept a reconstruction of the interior and exterior geometry of structural component including accurate 3D measurement of defects using x-ray computed tomography (CT); (2) allow for input of material prop ...
