ABSTRACT:The goal of the Space Test Program is to enable the US Air Force to rapidly develop emerging space technologies by providing economical flight opportunities to increase a technologys TRL. Over the past decade, the CubeSat form factor has emerged as an economical platform for testing technologies that can be packaged within the 10x10x30 cm form factor. However, the lack of a programmable S ...

This project improves the capabilities of hardbody optical signature programs to accurately support predictions in visible wavelengths. These improvements are primarily associated with 1) advancing Bidirectional Reflectance Distribution Function (BRDF) measurement techniques and associated databases, 2) providing accurate representations of the Earth radiance for any geographic location, time-of- ...

ABSTRACT:Specialty elastomers, such as hydrogenated acrylonitrile-butadiene rubber (HNBR) and fluoroelastomer (FKM), are widely utilized as high performance seals in numerous aerospace vehicles and components. The elastomer sealing industry and its products are primarily based on a limited pool of feedstocks that were last advanced in the 1970's. Using current technology, elastomeric seals must b ...

ABSTRACT:This Small Business Innovation Research Phase I project will develop a vacuum compatible, high gradient insulator (HGI) based on low SEE yield aluminum nitride (AlN) ceramic with high surface flashover resistance for pulse power applications. In Phase I we will design and fabricate AlN-Metal HGIs, and investigate the effects of AlN and metal layer thicknesses, and number of layers on the ...

ABSTRACT:The objective of this solicitation is to develop real-time automatic scaling software for oblique ionograms (OIs). The NWRA team has developed an extensive HF propagation computational tool set, which includes a capability called APEx (Automated Point Extraction) for automatically finding vertical ionogram (VI) traces within an ionogram image. APEx does not require pre-separation of the O ...

ABSTRACT: With the increasing demand on structural performance as well as decreasing size and weight of advanced flying structures, there is a reduction in the available volume for aircraft instrumentation. In addition, integral fabrication of structures using composite materials and close integration and optimization of aircraft system and subsystems limit further access and space for sensors, ...

ABSTRACT: To produce high dielectric strength insulator materials, our approach, called Optimized Additive Manufacturing for High Dielectric Strength (OAHDS), will optimize fused filament fabrication (FFF) 3D printing in order to fabricate high density parts. Currently, thermoplastics 3D printed via FFF have dielectric strengths one to three orders of magnitude lower than injection molded parts ma ...

ABSTRACT:The need for a natural language query capability for DoD regulations is identified. A technical solution based on artificial intelligence, cognitive computing, and natural language query technology is presented. In Phase I, various techniques will be investigated, and one or more solutions will be developed and tested. In Phase II, the down-selected technologies will be refined and built- ...

ABSTRACT:Abstract: Electromagnetic signals used in communications and sensor systems can be seriously impacted after propagation through a region of the atmosphere or ionosphere disturbed by turbulence. This work will develop new physics-based technology that calculates EM propagation from HF to laser frequencies, including the effects of turbulence with long correlation length in the direction of ...

ABSTRACT:Systima Technologies, Inc. proposes the development of an unmanned hypersonic test vehicle recovery system that will greatly enhance the effectiveness of hypersonic flight testing.Systima plans to perform a comprehensive review of the various hypersonic vehicle test environments and recovery requirements in order to develop recommendations for suitable vehicle recovery technologies for th ...
