Accurate Automation Corporation proposes to develop a system design for an Ultra Short Pulse Laser beam director. The design and analysis will investigate diffractive and non-diffractive beam shapes as well as refractive and reflective laser optics. A high definition video camera along with a laser range finder and video processing will be used to keep the beam director locked onto the target whil ...

ABSTRACT: Combustion instability (aka thermoacoustic instability) is a significant issue in propulsion systems including augmentors. Oscillations can increase heat transfer to walls 10 fold and cause vibration damage to the propulsion system and the surrounding system. This damage can occur very rapidly. Combustion instability (CI) is challenging to design for due to the complex interactions betw ...

ABSTRACT:The SBIR primary objective will be to show the feasibility of advance modeling for simulating and predicting the surface corrosion leading to fatigue damage. This capability will produce early-life stage models which will enhance state of the art corrosion analysis. The SBIR conceptual modeling method must address small damage, in a corroded microstructure for fatigue crack growth. The me ...

ABSTRACT:The damage tolerance approach is used widely in the aerospace industry and has a physics-based foundation in fracture mechanics. The fatigue crack growth rate can be determined by calculating the SIF (stress intensity factor) and knowing empirically derived material parameters. Similitude is achieved for different loads, different crack sizes, and different crack shapes. The down side to ...

A large portion of the non-recurring cost of throttling type valves is associated with the effort to evaluate the dynamics of the flow through the valve. Not only do these flow dynamics affect the structural and mechanical design of the valve, they have been shown to have an effect on the combustion stability of the rocket engine. Without a means to evaluate the valve dynamics, valve developers ...

The software system, Sensor Atom Configuration Software (SACS), will use of knowledge management techniques through ontologies capturing knowledge about sensor atoms and 3D targets, advance algorithm design, and concept of operations to allow for flexible sensor system design and predict sensor performance. Sensor atoms are the fundamental unit of a sensor embodying the most basic properties in te ...

AAC will consolidate an existing set of server applications, migrating the system to more practical hardware while maintaining all system functions. Advanced VM capabilities ...

In the last decade, researchers have investigated nanofiber based medical vehicles for various biomedical applications. The challenge is to produce nanofiber vehicles outside laboratory environment for clinical trial. This proposed effort is targeted at developing a cGMP compliant prototype process to demonstrate manufacturing of tissue scaffold. During PhaseI, an innovative scaffold will be made ...

Accurate Automation Corporation proposes to develop a system design for a self-contained missile launchable RF Generator based on a frozen wave transmission line technique. The RF transmission line will be charged through an optically activated switch fabricate from silicon carbide. A high energy pulsed laser with an electronic timing control will connect to the switch via an optical fiber. A high ...

In the Phase I effort, GTL will demonstrate the feasibility of the SMFB technology for fusion bonding of thermoplastic matrix composites. GTL will perform a series of experiments to quantify the effectiveness of various SMFB configurations. The effort will also explore several options for introducing the required heat to melt the thermoplastic around the SMFB. Once these data are known, GTL will f ...
