Current depot-level manufacturing systems are not responsive to changing requirements and flexible specifications. The serial arrangement of individual work cells results in a lengthy timeline to complete the critically-needed part; thus, critical assets

With today's IRLED devices, >99.4% of input electrical power is converted into parasitic/waste heat. Moreover, as the local temperatures of the pixels increase due to the generated heat, IRLED optical efficiency is further reduced. Overall this severely limits the number and intensity of array pixels that can be simultaneously operated at high apparent temperatures. In Phase 2, we focus on develop ...

High pressure compressor blades are subject to damage due to debris strikes and warping due to the elevated pressures and temperatures within the engine. Blade repair is currently performed manually using grinding to blend out the damaged regions. Reliance on manual grinding operations requires highly skilled operators, fails to reach the optimal blade shape, lacks repeatability, and is extremel ...

The Air Force has identified a need for a display agnostic common streaming model for 3D data. Third Dimension Technologies (TDT) and Oak Ridge National Laboratory (ORNL) have formed a consortium to define a 3D streaming model based on open standards for Display Agnostic 3D Streaming (DA3DS). Two factors are driving this need. The first is the dramatic increase in the collection, storage and trans ...

Developers of modern software, particularly those targeting mobile or embedded platforms, are presented with a wide variety of hardware choices. Solutions can be built on microprocessors (e.g. x86, ARM, or Power architecture), GPUs (e.g. NVIDIAs Tegra), DSPs, FPGAs, or some combination of these technologies. Not only does this place a significant burden on programmers in understanding the intricac ...

Hypersonic flight environments can include motion with high frequency spectral content that is difficult to simulate.This high frequency vibration may adversely affect the accuracy of guidance and control sensors, so it is very important to the Air Force Research Laboratory to be able to recreate the motion in a way that allows sensor performance to be evaluated.Motion platforms such as the KHILS ...

Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make large effective apertures in low SWaP form factors thereby maximizing achievable resolution. This sensor ...

ABSTRACT: Spacecraft power management relies upon DC-DC converters to provide multiple voltages from the storage battery. Currently available converters have shortcomings in areas of power density, tolerance to radiation and wide operating temperatures, and excessive development cost. We propose to develop a high density power converter that is compatible with spacecraft operational environments a ...

Inspection of inserted compressor blades is difficult due to the complicated geometry of the blades, the need for high accuracy, and the safety risk posed by undetected cracks. At present, the time and cost associated with airfoil inspection forces many

Use of motorcycles helmets significantly reduces the risk of fatality or serious brain injury to riders in the event of a crash, but riders often do not wear helmets in warm weather because of thermal discomfort. We propose to develop an innovative ventilation and cooling system that will maintain a cool, dry environment inside the helmet while also meeting applicable safety standards. The key the ...
