The Phase II program proposed here represents a novel approach to provide a PC-based tool for the design and evaluation of Visual Landing Aids (VLAs) in supporting Naval aviation launch and recovery operations. The software is based on the use of a suite of tools built around Virtual Reality Modeling Language (VRML) and X3D constructs. VRML and X3D are open 3D graphics standards supported by sev ...

In Phase I, a demonstration SUpersonic Rain Erosion (SURE) facility was developed which demonstrated the capability of producing spherical, millimeter-sized droplets repeatedly at velocities up to 1200 feet per second. Data were collected to extend the speed range of the facility and droplet size. Based on these results, a Phase II prototype facility will be built that could attain speeds of 240 ...

Current Navy simulations for representing Dynamic Interface (DI) operations are often restricted to include only one aircraft interacting with a ship airwake structure. Phase I work identified extensions to Continuum Dynamics, Inc.'s CHARM module for computing free vortex wake structures from rotorcraft that permit multiple aircraft interactional aerodynamic effects to be modeled simultaneously. ...

Accurate performance prediction is crucial to the simulation, analysis and flight testing support of rotorcraft. In this regard, current analysis tools inadequately model key phenomena like blade dynamic stall, rotor tip loads, and rotor downwash because of their failure to predict the true unsteady three-dimensional nature of the aerodynamic environment near the rotor. Continuum Dynamics, Inc. ...

The field of hyperspectral imaging has undergone tremendous development in the past decade. Research and development of the hyperspectral imaging in military applications has primarily focused on air-to-ground and space-to-ground reconnaissance of stationary military targets and terrestrial backgrounds. In this SBIR program, researchers of Dymas Research propose an innovative hyperspectral imaging ...

Near-infrared light (NIR) can detect intracranial hematomas with good sensitivity and specificity. However, commercial systems have not proved clinically useful. Early detection of hematomas is important for emergency head injury evaluation. The resulting pressure can cause significant brain damage or death, yet the pressure can be relieved if detected. We propose to create a portable NIR system ...

The proposed effort will actively reduce noise from flight operations at watchstander stations below the flight deck to levels that do not require hearing protection. Long-term hearing loss of personnel is projected to cost the Navy on the order of $12.6 billion over a 30 year retirement period. Active noise reduction (ANR) has long been known as the best method of controlling low-frequency nois ...

Highly reactive nanocomposite powders will be consolidated into solid shapes suitable for use as structural components of munitions. Nanostructured, reactive composites of intermetallic or thermite compositions have been prepared recently by Arrested Reactive Milling (ARM). Specific materials prepared previously include compositions in the systems Al-Fe2O3, Al-MoO3, and B-Ti. The prepared nanoco ...

Recent advent, and significant progress made in the wide-band-gap semiconductor technology offer today a promise for a superior high power phase shifter. More specifically, emerging Gallium Nitrate (GaN) HEMT devices are shown to operate in extreme temperatures (~600C), exhibiting high breakdown voltages (~100V) and high current densities (~1.5A/mm). In order to meet these challenging technical re ...

The objective of this proposal is to demonstrate the feasibility of an innovative design that utilizes ozone to break the oil-in-water emulsion stability in bilge water by oxidation. Ozone, a very strong oxidant, is capable of reacting with many substances by either directly or indirectly attacking the bonding substrates. This process can convert surfactant coated oil into a non-polar sensitive ...
