Main rotor shafts, specifically those used on the CH-47, are among the largest, heaviest, and highly loaded single components on rotorcraft. As the materials technology used in these shafts are decades old, (carburized 9310) there exists an opportunity to redesign the component with state-of-the-art materials technology and reduce component weight 20-25%. Carburizing alloys available today may als ...

The Army has a critical need for high performance robotic mobility platforms that can quickly and efficiently traverse challenging terrain, particularly those that would be encountered in a wartime urban environment. In order to accomplish these tasks, such robotic vehicles must have continuous contact and discrete contact locomotion modalities (e.g., tracks and legs) and must have the intelligen ...

The proposed miniaturized antenna takes advantage of two innovations. These include the novel antenna design concept of coupled sectorial loops and a wideband artificial magnetic conductor substrate utilizing a combination of dielectric and ferromagnetic (ferrite) materials. At its lowest frequency of operation, a coupled sectorial loop antenna (CSLA) can be designed to have maximum dimensions of ...

In this Phase I SBIR program, QuesTek proposes to apply its Materials by Design® technology to the design and development of a new castable titanium alloy. Microstructural concepts for the alloy design will focus on improved castability (near-net-shape formability), improved mechanical strength (including fatigue strength), and lower cost relative to the existing aerospace-grade Ti-6Al-4V alloy. ...

Laser designation plays an essential role in today’s high precision combat environment. The stability of a laser designator is currently limited by the ability of the user to hold the laser on the target. Currently, the only tool to assist the soldier to minimize the beam pointing error is to use a relatively heavy tripod. Given the amount of gear ordinarily carried by today’s soldier, it woul ...

Research is proposed to investigate the feasibility of a high-isolation transmit/receive antenna system for Army land vehicles, using an innovative, circuit-domain, distributed, RF-passive cancellation system with active feedback control. Conventional time- and frequency-domain cancellation approaches have inherently-narrow cancellation bandwidths due to applying amplitude and phase adjustments or ...

A novel surface passivation technique is proposed for InAs/GaInSb-based strained layer superlattice focal plane arrays with a pitch of 15 µm or less. Buffered oxide and sulfur-based surface treatments prior to dielectric deposition are proposed as the most suitable and chemically stable surface treatments. Both processes result in the removal of elemental oxides, while the latter additionally pro ...

The Xenotran Corporation and PrismTech Solutions Americas Inc. (PSA) (the “Team”) along with the U.S. Government proposes to design and develop a comprehensive Software Defined Radio (SDR) tool suite to aid in the development, porting, integration, debugging and analysis of waveform software. This tool suite is comprised of two tools, a Core Framework (CF) Analysis Tool and a SDR Diagnostic To ...

The U.S. Army's soft-sided shelters are in need of lightweight, modular, fire resistant, ballistic protection panels that will provide sufficient blast defense for personnel and equipment within the shelter. Texas Research Institute Austin Inc. (TRI/Austin) proposes a novel composite armor paneling system that can afford this protection by dissipating the energy of the blast while subsequently pr ...

Power demands of objective force warriors are rapidly growing, increasing the need for small, light, energy-dense power supplies. The burden of batteries an individual soldier transports must be reduced. High energy density fuel cell systems offer a promising alternative to batteries with methanol being the most portable, convenient fuel. Conventional direct methanol fuel cells (DMFC’s) based ...
