There is a need to achieve 10^-9 reliability for actuators for critical aerospace applications and this precludes single point failure for all but the simplest and most reliable electrical and mechanical components. LC Drives proposes a method of constructing a high reliability linear actuator for critical aerospace applications that is designed such that jams caused by conventional electrical a ...

Fiber reinforced composites are attractive for several light-weight defense and aerospace applications. However, their inherent anisotropy and complex failure mechanisms limit their use in high-performance structures or components. In order to accurately predict the damage behavior and durability of composite parts exposed to extreme conditions, there is a need to develop new analysis tools that c ...

In this Phase II SBIR project, Daniel H. Wagner Associates (DHWA), with NASAs Jet Propulsion Laboratory (JPL), MARK Resources, Inc. (MRI), and Spatial Integrated Systems (SIS) as our subcontractors, will develop a prototype lightweight, low-cost Wave Detection, Prediction, and Reaction System (WDPRS), and then test and evaluate its performance at-sea. The proposed WDPRS is designed to reduce the h ...

ABSTRACT: The ultimate goal of this Phase II SBIR is to provide the Air Force with a game-based approach to train Air Force maintenance personnel. Sonalysts believes that the most cost-effective solution will include: The continued development of specifications for a SAM-T that uniquely uses game engine AI, scenario generation, IMI, IETMs, event management, performance tracking tools, and eve ...

ABSTRACT: Sheets, or"mats"of EMI protective materials have critical value for many systems of strategic importance for the Department of Defense (DoD). It is of great importance that all such materials that are integrated into fielded systems are fully capable of meeting shielding requirements; however, detecting defects or flaws that compromise performance using current methods is extremely tim ...

The proposed effort will seek to further design and develop vacuum brazed high density folded-fin modular heat exchangers. The scalability of these heat exchangers would provide a means for fabricating large area high performance cold plates by joining via friction stir welding. The advantages of this approach would be an increase in system performance, reliability and efficiency. From a manufactu ...

ABSTRACT: This proposal describes an analytical software approach to model rolling element bearings for gas turbines and similar drive systems. Detailed approaches for modeling bearing material fatigue life, oil churning, and tribology are presented. The resulting analytical bearing code will enable gas turbine engineers and designers to better assess engine lubrication system thermal loads and ...

Phase I of the STTR program will be a collaborative research effort between high fidelity computational simulations and experimental testing. The primary aim of this initiative will be to measure laser beam distortion, using aero-optic metrics, due to flowfield turbulence. The results from the computational simulations and experimental test will be compared to ensure agreement between the two. Ini ...

Corrosive environments together with cyclic loading can lead to the formation of localized corrosion pits and corrosion fatigue cracks, which can significantly deteriorate the structural integrity of aircraft components. The exact nature of corrosion fatigue damage is dependent on the competing multi-scale processes resulting from complex interactions between the structural material, its environme ...

It is critical to the safe use of ceramic matrix composite components that information on the fracture toughness of these materials be available, in order to allow an assessment of the likelihood for crack growth. Although Military Standards and American Society for Testing and Materials both serve as resources for room and elevated temperature test methods, there are no standards to obtain the in ...
