This proposed study intends to develop a model and prototype of a flapping winged vehicle through the incorporation of elastic components. This will allow the manufacture of such vehicles with greatly enhanced flight duration and agility. Work will include the design, prototyping, and testing of micro air vehicle wing flapping mechanisms with tunable elastic components for increasing throughput po ...

Linearizer Technology Inc. produces analog predistortion linearizers. Integrated with a power amplifier (PA) and used for SATCOM applications they approach the performance of an ideal amplifier. Limitations of LTIs linearizers are the need for meticulous tuning to achieve the desired characteristics over frequency, and the need for adjustment to match a PAs specific characteristics. LTI has d ...

Because of the overwhelming migration to composites, particularly exotic thermoset materials from the bismaleimide (BMI) family, the PNTS team is focusing its work on this topic on composite structures. The team's high level approach will be to demonstrate an innovative and practical design using dielectric spectroscopy at millimeter wave through terahertz frequencies that will provide compos ...

MSI successfully demonstrated modification of its existing extended range 40mm non-lethal munition to carry and deploy a molecularly imprinted polymer (MIP) payload intended to detect and confirm explosives at 100m stand-off. Based on analysis and air-gun testing, as well as legacy performance of MSIs munition, key characteristics of the explosive detection munition include over 25 square inch co ...

Millimeter-wave RADAR imaging holds significant promise for many applications from rotorcraft DVE mitigation to standoff security screening. A key challenge of this imaging modality, however, has been the implementation of an effective method for creating an image without relying on either mechanical scanning or expensive, high SWAP phased array techniques. Herein, we present a concept for creat ...

New enhancements to mobile computers including smaller sensors, displays and powerful processors have made them much more attractive for the battlefield, not only as wearable systems for soldiers, but also unattended ground sensors a warfighter can leave behind for situational awareness. Unfortunately, while the technologies for hands-free interfacing have improved greatly, the challenge of limiti ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Accurate flow calculation is crucial to the development and support of air platforms, and CFD has been successful at predicting aerodynamic performance for a variety of flows. The accuracy of CFD is governed by the quality of the surface mesh, and much work has been undertaken to automatically generate surface grids from CAD. Unfortunately, quality is quantified in terms of conformance to the surf ...

This SBIR Phase I proposal is aimed at the development of the ultra-sensitive detector for the far infrared (FIR) and terahertz (THz) bands of electromagnetic radiation. The device is inherently optical, operates at room temperature and of submillimeter size. The proposed technology is based on coupling the radiation to be measured to the mechanical degree of freedom of an optical microcavity and ...

The Phase I project analytically demonstrated that significantly improved engine cooling fan performance levels can be achieved for Paladin Integrated Management (PIM) vehicle that uses the same engine as the Bradley Fighting Vehicle, and the heavy payload variant of the Joint Light Tactical Vehicle (JLTV). The Phase I project provides a solid foundation to implement highly efficient cooling fans ...
