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 environmen ...

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 int ...

ANP Technologies proposes to integrate a commercially available air sample concentrator from ICx MesoSystems with our automated detection instrument that uses the NIDS® multiplexed assays and NIDS® Auto-Reader (AR) device. A trigger device may also be incorporated into the final system, which might better enable the system to serve as a remote monitor of air streams. The proposed effort will b ...

Blade-to-blade variations in frequencies lead to the phenomenon of mistuning. Even very small amounts of mistuning can cause some blades to vibrate much more than others. Mistuning can cause an amplification of resonant response by up to 400 percent, and has been identified as a primary factor in HCF failures. One issue in setting blend limits is whether or not the blending operation will exacerba ...

The overall goal of this STTR program is to develop an efficient, high-fidelity, CFD-based design tool for the simulation of ship-board flight testing of autonomous UAV systems. In Phase I, an overall flight simulation framework that employs a modular approach to the flight simulation problem was developed. The effort was successful in demonstrating a lower-cost aerodynamic modeling approach tha ...

The inlet section of a high speed supersonic (Mach 2 to 5+) missile captures and compresses the free stream flow, slowing it down to subsonic speeds (through a normal shock) where it is fed into the combustor section. Through the use of design optimization and high-fidelity CFD analysis, CRAFT Tech and University of Minnesota are developing a new tool for high-speed inlet design that will evaluate ...

FPGAs have attracted a great deal of attention over the past decade because of their performance, scalability, and cost relative to traditional hardware platforms. However, one of the most significant disadvantages of FPGAs is based on the underlying architecture on which they are built. Specifically, routing delay through the chip is one of the largest bottlenecks in developing FPGA-based appli ...

KCF Technologies will develop compact Power Harvesting devices to enable Navy distributed wireless sensor systems. The power harvester will be developed as an enabling component in RLW Inc.’s S5NAPTM wireless sensor. The target application, in collaboration with JCI/YNS, is Condition Based Maintenance of AC plants on Navy ships and submarines. Follow-on applications will expand the deployment ...

This Phase II project will develop a system for the perioperative management of head trauma patients that is compliant with the proposed Integrated Clinical Environment (ICE) standard. Device interoperability will be implemented using a microprocessor-based adapter that translates communication protocols of specific legacy medical devices into a standard protocol readable by an open-source API. T ...

Prior work has indicated that a trimodal, cryomilled, Aluminum matrix has potential for being a lightweight armor. Recent data has indicated the need to confirm the most cost effective and repetitive manufacturing process. This Phase II STTR proposal addresses that need.
