"The aim of our Phase II activity is to incorporate the Cohesive Volumetric Plate and Shell (Finite) Elements into LS-DYNA3D, thus enhancing its capabilities in modeling HRAM loading and damage in composite structures. In Phase I, we reported oninterlaminar failure criteria and modes, based on fracture mechanics. A damage-dependent bilinear cohesive element is used to capture the crack initiatio ...

"A method for generating a high power, continuous wave (cw) monolithic micro-laser with rapidly tunable, narrow linewidth output is proposed. The concept employs a semiconductor laser coupled to an electro-optically controlled Bragg waveguide in PotassiumTitanyl Phosphate (KTP) providing single frequency output. Frequency tuning is achieved by applying a voltage across the waveguide, thereby cha ...

"The acoustic signature generated by test articles in high speed wind tunnel tests is difficult to measure due to the high level of background noise created by the wind tunnel flow. A unique research program using microphone arrays is proposed to addressthis issue. The program combines experimental tests and analytical algorithm development to devise a system able to reject the undesirable wind tu ...

"Aetion Technologies LLC will study the feasibility of applying its SFV decision-support technology to modeling, Monte Carlo simulation, and analysis of depot shop processes. The project will assess whether SFV can be used to model heterogeneous depot shopelements and systems with multiple states at multiple levels of resolution, and to simulate the flow of items through them. By running many simu ...

"Sandwich structural designs are the most weight efficient concepts for stability-critical components such as control surfaces. The objective of this proposal is to demonstrate the feasibility of producing honeycomb sandwich structure using a unique DoubleWalled Honeycomb design. This new ARDL honeycomb design is called Hexagonal Double walled structure or "HexD" This is depicted in Figure 1.HexD ...

"Development of compact, high energy, pulse power capacitors is the gating technology for Pulse Forming Networks (PFNs) used in directed energy and kinetic energy weapons and microwave systems. This proposal is to explore high permittivity (high-қ)dielectric films and superior electrode materials in a solid state configuration to obtain capacitors that have high voltage breakdown and low leakage ...

"The proposed effort will research development of an onboard 1 MW auxiliary power unit (APU) and cooling capability for installation on heavy aircraft. One important objective is that the total package that includes a generator, a prime mover, and anauxiliary compressor to weigh no more than 1400 lb. Such a solution does not currently exist. Development of technical objective is to be carried o ...

"Applied Optimization, Inc. proposes to develop a solution to monitor the health of the GPS Block II, IIA and IIR satellites using the LWIR and Visual Spectrum intensity tracking data obtained by a SBIRS-Low satellite. The Phase I calculations havedemonstrated that the radiometric signature for older GPS satellites is stronger than their newer counterparts. This is consistent with the fact that th ...

"During this project, Applied Sciences, Inc. (ASI), and its strategic allies, seek to exploit the unique combination of electrical and dimensional properties found in carbon nanofibers to minimize both differential and absolute charging of satellites, andthe dangers presented by such charging. Methods to be developed include: 1) incorporation of nanofibers into the dielectric materials commonly u ...
