A SIMPLE SAFETY ARMING SWITCH FOR GUIDED MISSILES CAN BE BUILT AROUND AN ACCELEROMETER AND INTEGRATING CIRCUIT. IN GENERAL, DURING THE LAUNCH BOOST PHASE, THE ACCELERATION OF A MISSILE INCREASES TO A MAXIMUM JUST BEFORE BURNOUT. CHARACTERISTIC ACCELERATION PROFILES FOR A PARTICULAR MISSILE ARE DEPENDENT UPON FUEL TAILORING AND MISSION REQUIREMENTS; I.E. AIR-TO-AIR MISSION, GROUND-TO-AIR MISSION, E ...

Given the high cost and criticality of training, decisions about which training methods to employ and how best to use them are vitally important to today's military and to the commercial sector. Unfortunately, most training decisions are made in the absence of meaningful or valid information, often without appropriate representation from relevant stakeholders. A better informed and structured de ...

Bends in waveguides are a problem for high-voltage Ultra-Wideband (UWB) systems. The difficulty arises because only a straight section of standard transmission line can support a pure TEM mode. And a pure TEM mode is necessary to preserve the risetime of the transmitted impulse. When there is a bend in the waveguide, the transmitted signal is a broader impulse than the incident signal. This ca ...

Maintaining straightness of continuously welded high speed DoD track rails is critical to the facility's mission, since test vehicles, often traversing the track at up to Mach 10, can experience dangerous dynamic loading due to track irregularities. Although facilities are constructed with adequate pretension to reduce undesirable effects of irregularities and thermal expansion/contraction over w ...

There is a critical need for an all weather capability to detect and classify military targets concealed in foliage and/or camouflage. Recent advances in high resolutions synthetic aperture radar (SAR) technology, operating at low frequencies (VHF-UHF), have demonstrated significant capability for detection and classification of such targets. However, one of the primary difficulties is the signi ...

CURRENT NUMERICAL COMPUTATIONS TO DESCRIBE NUCLEAR GROUND SHOCK ENVIRONMENTS, NUCLEAR CRATER FORMATION, IMPACT DYNAMICS AND PENETRATION MECHANISMS PRESENTLY EMPLOY EULERIAN-BASED FINITE DIFFERENCE CODES BECAUSE OF THEIR ABILITY TO MODEL THE MASS FLUX PHENOMENA IN TRACKING MATERIAL MOVEMENT THROUGH THE DISCRETIZED SPACE. THE FINITE DIFFERENCE CODES SUFFER IN COMPARISON TO FINITE ELEMENT CODES, HOWE ...

THE MECHANICAL PROPERTIES OF BRITTLE MATERIALS UNDER HIGH STRAIN RATE LOADINGS IS A MAJOR CONCERN TO THE AIR FORCE IN THEIR DEVELOPMENT OF LOW COST AND HIGHLY SURVIVABLE MATERIALS. THE ABILITY TO VIEW THE MICROSTRUCTURE EVOLUTION DURING SHOCK LOADING IS CRITICAL TO GAINING A BETTER UNDERSTANDING OF THE MATERIAL DUE TO RATE EFFECT. AT PRESENT NO DIAGNOSTIC INSTRUMENTATION IS AVAILABLE TO MAKE REALT ...

ILINC proposes to develop software tools for facilitated synchronous and asynchronous training through Internet or intranet networks. These tools will allow training and performance support at a distance using standards based technologies and cognitive approaches that are of demonstrated effectiveness. The objective of Internet access is to reduce/control costs of training. The tools would be d ...

Real-time video enhancement can be accomplished in two areas. First, optics and optical systems can readily be applied to the incoming image. The nature of this solution is such that the results occur in real-time. Secondly, if the video is to be digitized, a variety of hardware and software solutions can be applied to the digital data. Processing time is the single largest constraint on digit ...

This Phase I SBIR demonstrates the underlying technology required to construct an ultraspectral imager that has the ability to spectrally resolve molecular absorption lines while simultaneously creating a two dimensional spatial mapping. The proposed instrument will have a spectral resolution that is better than 2 cm-1 and two dimensional spatial resolution that exceeds 2 milliradian. Based on Fou ...
