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 ...

Since the 1990's, applications requiring high power (>1 KW) millimeter wave energy have relied on either gyrotrons or multiple gryotwystron amplifiers. While the gryotwystron approach offers bandwidth and single point failure benefits, it is inherently more complex and larger than that of the single gyrotron. The gyrotron however requires a superconducting magnet to create the 3.7 Tesla field ne ...

We propose to determine what outputs from the SSAJ measurement system would be suitable for traffic control applications, to determine what the "real time" needs and accuracies are for measurements of signature, speed, acceleration, and jerk (SSAJ), to integrate the output of our IST-222 Standard Signature Output Card with and Advanced Transportation Contorller (ATC) and finally to demonstrate pro ...

Accurate projection of costs remains an intractable problem in the defense industry despite more than a decade of focus on affordability. The impact to DoD acquisition programs, from cost escalation and the cost of countering capability shortfalls, runs to billions of dollars annually. The objective of this proposal is to develop and demonstrate an ontology-based framework for requirements-based ...

This SBIR program will develop a novel software methodology for the management of gas turbine usage data in real time for accurate prediction of engine life. The approach will be flexible enough to allow for re-assessment of life consumption when subsequent knowledge provides a revised understanding of the way the damage is accrued. Phase II will further investigate potential data compression meth ...

As the Army’s current fielded ground combat and combat support systems continue to age, there are increasing performance and reliability issues being encountered by our troops. Vehicles and equipment once designed using the best practices available at the time, can now be better engineered through state-of-the-art computational processing through coupling of engineering, business and maintenance ...

Air Force engines are required to satisfy both safe-life and fatigue crack growth (damage tolerant) design criteria under the engine structural integrity program (ENSIP). To achieve this requirement, nondestructive inspection techniques are used to detect cracks that can potentially grow to failure within the next inspection interval. However, these nondestructive inspections cannot be performed o ...
