Silver thiogallate, AgGaS2[sub], is an attractive nonlinear crystal for the generation of tunable laser radiation from 2 to 12 microns. Its application is limited by surface and bulk absorption. It is proposed to address this absorption problem by characterizing single crystals grown from off-stoichiometric Ag2[sub]S-rich solutions, as well as from conventionally grown crystals from near stoichio ...

Successful rocket sled testing stretches the limits of known science in many areas including aerodynamics, thermal heating, impact dynamics and material structural integrity to name a few. As sled speeds and payload weights have increased over recent years, the margin of tolerable error in engineering judgment has been shrinking. Computational tools for predicting aerodynamics and structural res ...

The Holloman High Speed Test Track (HSTT) requires the ability to accurately predict the amount of wear occurring on rocket sled slippers during testing. The sliding interface speeds and pressures experienced by slipper materials on the HSTT rail far exceeds any phenomena studied and documented to date. During the Phase I effort, a math model was developed to predict slipper wear using the free ...

A CENTRALIZED FAULT DIAGNOSIS AND CORRECTION (CFD&C) SYSTEM HAS THE BASIC REQUIREMENTS OF MONITORING THE HEALTH OF THE TARGET SYSTEM, DETECTING AND DIAGNOSING ANOMALIES AND RECOVERING FROM THE ANOMALIES. THIS PROPOSAL DESCIRBES THE DESIGN OF A CFD&C WHICH WILL HAVE THE CAPABILITY TO PERFORM ON-LINE DIAGNOSTICS AND CORRECTION FORM A CENTRAL LOCATION WITHIN A MULTI-NODE CONFIGURATION OF ELEMENTS. TH ...

The Microballoon Manufacturing and Autopilot Development Program proposed under the scope of this effort is a comprehensive initiative focusing on advancing the production process and flight controls of stratospheric microballoons. The program emphasizes

This Small Business Innovation Research Phase I project is to develop a compact deployable micro immersive display component for augmented reality (AR) and virtual reality (VR) based simulation, training, exercises or mission rehearsal applications. The proposed display component is an eye protection goggle type wearable high resolution stereo display. With head tracking and registration, it enabl ...

Small Unmanned Aircraft Systems (SUAS) platforms fit into the USAF Intelligence, Surveillance, and Reconnaissance strategy by providing local persistence, operation in contested environments, and low probability of detection. SUAS gimbal performance is typically limited to full color full motion video, limiting target detection and identification information available to image analysts and detecti ...

AIRCRAFT DESIGNED FOR FLIGHT IN THE MACH 3-6 RANGE MUST INCORPORATE ACTIVE COOLING IN THE TURBORAMJET PROPULSION SYSTEM. THE REQUIRED COOLING CAN BE PROVIDED BY AN ENDOTHERMIC REACTION OF THE FUEL. ENDOTHERMIC-FUEL REACTORS MUST BE SMALL AND LIGHT. HEAT TRANSFER TO THE LOW THERMAL-CONDUCTIVITY, CERAMIC, CATALYST SUPPORT IS A MAJOR LIMITATION TO THE REACTOR DESIGN. TDA RESEARCH PROPOSES TO FABRICAT ...
