The accurate representation of the rotor wake, especially the tip vortex structure, in a computationally efficient and algorithmically straight forward way is crucial for prediction of rotor aerodynamic performance, noise emission, and rotor structural dynamics. A promising approach for design and optimization is the vorticity confinement (VC) method that minimizes the numerical diffusion of vorti ...

The Quantum Engineering Design, Inc. (QED) Mission Module Handling Device (MMHD) is designed to meet the Navys requirements of minimizing the deck point loading while lifting and omni-directionally maneuvering ISO containers and Twenty foot Equivalent Units (TEUs) aboard both the Littoral Combat Ship (LCS) Freedom and Independence class of vessel. Special attention is paid to the need for operatin ...

KaZaK Technologies and our program subcontractors and technical associates are proposing several concepts to reduce Medium Tactical Vehicle Replacement (MTVR) wheel hub weight to increase cargo capacity and improve vehicle handling. An increase in cargo capacity provides the MTVR to be outfitted with the MAS up armor protection minimizing impacts to vehicle performance. One obvious approach to red ...

In this Phase I SBIR program, QuesTek Innovations, a leader in the field of integrated computational materials engineering (ICME), proposes to design and develop novel aluminum alloys specifically optimized for the unique processing conditions and challenges of Additive Manufacturing processing. QuesTek is uniquely suited to rapidly designing new aluminum alloys specifically optimized for AM proce ...

MicroLink Devices has developed, and is currently producing, thin epitaxial lift-off inverted metamorphic solar cells for flexible solar sheets using a four-inch GaAs wafer platform. These cells have been demonstrated in a variety of applications including panels attached to Marines"backpacks and the wings of Raven and Puma unmanned aerial vehicles (UAVs). Although good system performance has su ...

The primary objective of CU Aerospace"s (CUA) Phase I work will be to fabricate and test aromatic thermosetting copolyester (ATSP) composites for use as ablative thermal protection systems for next generation reentry bodies. Unfortunately, there has been little work put into the development of improved ablative materials over the last 30 years, most of the current TPS are based on"new"designs usin ...

In this SBIR program, QuesTek Innovations, a leader in the field of Integrated Computational Materials Engineering (ICME), proposes to develop and apply its microstructure-sensitive models to the"closed-loop,"location-specific prediction of nickel superalloy disk properties (e.g., strength). During Phase I, the goal will be to expand upon QuesTek"s DARPA-"Accelerated Insertion of Materials"effo ...

High-strength gear steels used in helicopter transmission components require a long service lifetime and enhanced fatigue resistance. As the current design approach of these materials uses empirical test data for stress/life predictions, these methods do not capture the scatter in the test data nor do they isolate the dominant microstructural mechanisms that govern fatigue crack initiation. Thus, ...

The use of directed energy at long distances, such as for aircraft defense, requires a high power (>100 W) light source within the mid-infrared spectral region (3-5 micron). Power scaling of individual quantum cascade lasers using 1-D and 2-D arrays seems to be a straightforward approach. However, this process is critically dependent on individual laser output efficiency and thermal management. Ex ...

Sagetech proposes a program that will give rise to a 150 gram Mark XIIA Level 2 IFF Micro-Transponder with ADS-B that meets all requirements for deployment in a Group 2 UAV. The device will be designed to interface initially with a KIV-77 crypto applique, but will be replaced by a micro-KIV in subsequent phases. Phase I activity will focus on singling out those requirements and tests necessary for ...
