In Phase I of the proposed program we plan to demonstrate the feasibility of manufacturing bladetrack components using an approach that will result in substantial reductions in cost and cycle time compared with conventional 2-D lay-up methods. The approach involves use of a 3-D fiber preform with the shape of the final component, produced by an orthogonal weaving process developed at 3TEX, which ...

Strength, durability and reliability of commonly used bonded and bolted composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic properties, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature failure of adhesive bonded joints. The proposed work offers substantial enhancement ...

Many technical challenges will need to be surmounted to create practical cybercraft: assurance, control, rules of engagement, representation and discovery of the target environment, among others. However a serious challenge lurks behind all of these: scaling solutions to fleets of up to a million craft. New approaches are needed to deploy and control the craft at this scale. Failure to come to gr ...

Current base and force protection vulnerability assessments tools are limited in their ability to a) prioritize prevention, detection, and mitigation options based on adversary intent and defense objectives, b) share results between different sites and support new (rapid) force protection training as personnel rotate, c) reuse past analyses and keep adversary data, defender data and the resulting ...

With improvements in high performance military jet aircraft engines and the increase in complexity of the exhaust systems the noise produced has become problematic. Reducing these noise levels, while maintaining overall system performance, has become the driving issue in new nozzle designs. This proposal will focus on nozzle designs of practical application that can be implemented on current high ...

Alaska Native Technologies (ANT) and Johns Hopkins University-Applied Physics Lab (JHU-APL) have teamed to present an innovative, solution to the acoustic inversion sensor problem by combining a new, cost effective, high gain, broadband array (JHU, sponsored by ONR Code 32) with a new UUV (glider, ANT, sponsored by ONR Code 321) designed to operate in littoral areas that has extensive onboard proc ...

The proposed MFA is a complex, highly integrated architecture comprising a number of distinct radiating structures in a very compact package. The antenna design centers around a pair of conical radiators, which are DC (Direct Current) connected to the chassis/fuselage of the aircraft, as required in MIL-E-5400. These conical radiators are shared for simultaneous operation on 30-88 MHz, 118-174 MHz ...

Due to the phasing out of TNT usage in explosives due to safety and environmental concerns, insensitive explosives utilizing wax binders instead of TNT have gradually replaced TNT in bombs and other explosive shells. The wax material that has been the most utilized in this application has been carnauba wax, but due to its non-domestic production and its dependence on natural growth and harvest me ...

To address the Army need for development of designed-by-reliability zero-maintenance air filtration system for modernization of military air filtration systems for ground vehicles to increase the system service life and reduce operation and support costs, BuckyTech, LLC proposes to develop an Embedded Resonated Screen Air Filtration device, based on a new, highly efficient nano-fiber mesh with emb ...

Develop the Lightweight Aerostat System – Deployable Communications Network (LAS-DCN) to provide an inexpensive, long endurance relay capability for small ships such as the Littoral Combat Ship (LCS) or USVs. It can also be airlifted by aircraft or helicopter to remote sites if required. LAS-DCN consists of a communications relay payload suspended from a new type of small specially designed te ...
