SOLID BORON HAS LONG BEEN RECOGNIZED AS A POTENTIAL HIGH VOLUMETRIC DENSITY PROPELLANT FOR VOLUME LIMITED ROCKET AND AIR BREATHING PROPULSION SYSTEMS. HOWEVER, ACHIEVING THIS POTENTIAL HAS BEEN DIFFICULT DUE TO LOW COMBUSTION AND HEAT RELEASE EFFICIENCIES IN CONVENTIONALLY DESIGNED COMBUSTORS. A THREE PHASE MODEL OF BORON ASSISTED COMBUSTION IS POSTULATED AND THE ROLE THAT KINETIC SENSITIVITY ANAL ...

The use of Kinetic Energy Weapons (KEW) against theater missile threats, such as the SCUD, require fast and accurate aim point determination to maximize the kill probability. It is proposed to incorporate an innovative active three-dimensional (3-D) imager in each KEW seeker to significantly improve the kill rate. The proposed 3-D Imager uses a rugged laser diode illuminator to generate a narrow b ...

ARPA has identified an important need for improved noise abatement while providing increased fuel economy for automobiles and other motor driven vehicles. This proposal is responsive to this need. It provides for a Phase I project to design and prove the feasibility of a noise abatement device for use on automobiles instead of conventional resonators and mufflers. This concept uses active noise ab ...

Compromise of security networks is easiest through the communication links. Wired links between sensors and their controls require skilled preplanning and installation. They are expensive to maintain, especially in the connections to central security monitors and command centers. We propose to use a radio based communication system to replace the hardwire/fiberoptic links. This sysem is packet rad ...

ACOUSTIC RESONANCE CREATES A PROBLEM WITH BOTH THE OPERATION AND THE DURABILITY OF CURRENT HIGH PERFORMANCE GAS TURBINE AUGMENTORS. FUTURE GAS TURBINES ARE EXPECTED TO HAVE AN EVEN MORE SEVERE ENVIRONMENT FOR AUGMENTOR RESONANCE. THE CURRENT LEVEL OF UNDERSTANDING OF THIS PROBLEM GIVES NO ASSURANCE THAT SATISFACTORY PERFORMANCE CAN BE OBTAINED FROM THE MORE ADVANCED AUGMENTORS WITHOUT MAJOR DEVELO ...

Impulsive acoustic sources have several advantages and disadvantages On the positive side, they are highly mobile and deliver a high source level without the use of connecting cables. On the negative side, their combination of high power and nondirectionality yields a high background of reverberation or clutter that obscures the desired echo. In addition, the transmit waveform cannot be easily alt ...

An affordable processing and manufacturing system for production of fiber reinforced complex shape metal matrix composites (MMCs) is proposed. The composites are precision cast by pressurized infiltration casting. Thin-walled ceramic molds are used to contain and infiltrate complex-shaped preforms. A powerful, user-friendly 3D graphics software package is used to interactively create mold designs ...

Vertical Cavity Surface Emitting Lasers (VCSEL) offer unique optical and electrical characteristics including single mode operation, low power requirements, low beam divergence, circular beam shape and 2D configurability. As in any semiconductor laser these lasers lack temporal and spatial uniformity in wavelength for most present application. With the fast growing interest and development of appl ...

This SBIR proposes the development of an expendable probe required for in-situ or post analysis of environmental ocean measurements in support of Air Undersea Warfare (USW) surveillance systems. Variants may provide affordable monitors for commercial environmental applications. The technical objective is to formulate a design concept and demonstrate feasiblity of an air-deployed expendable multip ...

Aspen Systems proposes to develop a high speed, electronic camera that features a large format and a diode laser illuminator. This system will offer greater resolution and versatility than has been previously available. Using illumination from a compact laser diode, the new camera will resolve the image of an object (projectile, for instance) obstructed by intense ambient light (explosive fumes) ...
