ABSTRACT: The proposed effort builds upon previous results obtained independently by the Optical Sciences Company and in collaboration with the DARPA InPho Program and other AFRL activities to develop a quantum communication system between ground links and a constellation of satellites. To address the losses in the link an advanced adaptive optics system is used to provide a robust classical cha ...

IFOS proposes to develop a fiber-optic-based sensing system and a unified damage mechanism model utilizing an integrated fiber Bragg grating (FBG) sensor system for prediction of remaining useful life of rotorcraft structures. The proposed new rotorcraft damage modeling technique makes it possible to incorporate temperature and acoustic emission (AE) measurements with load tracking techniques for ...

Conduct comprehensive experimental tests using an existing microwave generated plasma igniter (M/W Igniter) that provides a continuously stabilized heat release source to suppress augmentor combustion instability or screech and to reduce the lean blowout (LBO) and light-off (LO) limits in modern/advanced or legacy augmentor flameholders. The test flow environments will include known combustion tes ...

Historically, aircraft engines have featured relatively simple axisymmetric exhaust shapes with several moving parts; however, future engine exhaust systems are expected feature compact, sinuous ducts with complex non-axisymmetric shapes, fixed exit areas, thrust vectoring etc., constructed with a minimum number of moving parts. Their exhaust plumes are currently not well understood; however, LES ...

Cascade Technologies and its collaborators from the Florida State University and Stanford University propose to develop a robust computational framework to enable geometrical optimization of complex non-axisymmetric exhaust systems with controlled accuracy and low computational cost. In this framework, Reynolds-averaged Navier-Stokes (RANS) surrogates will be constructed based on extensive databas ...

Humans are still unsurpassed in their ability to search for objects in visual scenes. On the other hand, object detection continues to be one of the hot areas of computer vision, and it attests both to the fundamental importance of the problem and the fact that existing state-of-the-art algorithms are still shy of performing well in practice. We propose to utilizes human vision modeling of a fovea ...

Toyon Research Corporation, together with the University of California, Santa Barbara (UCSB), propose to develop a Local Carrier-based Precision Approach and Landing System (LC-PALS) that provides a full navigation solution (3-D position and altitude) for platforms within range of an aircraft carrier equipped with at least one beacon. Preliminary analysis indicates that the system will achieve 10- ...

ABSTRACT: The secure transmission of digital information is of extreme importance for military and commercial applications. The need for protecting information from hostile eavesdroppers has motivated the search for novel security schemes. This EPR-based Quantum Key Distribution (QKD) approach promises to provide a final solution to the problem by insuring ultimate security based upon the laws o ...

We propose to develop a multi-functional coating technology using a three-component nanocomposites to achieve excellent syperhydrophobicity, anti-icing, enhanced track-resistance, and high dielectric breakdown strenght. The coating will be compatible with current Navy existing VLF device materials and be ease of applications in outdoor field, and be long lasting requiring infrequent applications.

Atomic Layer Deposition (ALD) offers a powerful technique for changing the surface properties of a material while maintaining the bulk properties. This allows one to create a new class of materials where one combines excellent bulk properties of lower cost materials, such as copper, with desirable surface properties of rare or expensive materials, such as tungsten, platinum, titanium, molybdenum, ...
