Aculight proposes the development of a frequency tunable source suitable for LADAR measurements from compact military platforms. The source will use a fixed frequency diode pumped solid state drive laser and an optical parametric oscillator, tunable from 1.6 to 2.4 microns. Output energies will be over 100 micro-J through the spectral range at pulse rates of 10kHz. The major technical challenge, ...

High pulse energy, high repetition rate, tunable, narrowband sources are needed for optical pumping of mid-infrared gas laser converters. The source needs continuous tunability over the 1-3 micron band to access different overtone bands in various gaseous gain media. Due to the need for diode pumping of the source, efficiency is critical to minimizing diode costs. Our approach is efficient gene ...

A Cartesian, multigrid, Euler solver is investigated for development as a module suitable for the multidisciplinary design optimization (MDO) environment. The ultimate objective is not to improve the Euler solver (it is already a mature code) but rather to augment or replace the linear panel method flow solvers used in the Automated Structural Optimization System (ASTROS) for the purpose of airfr ...

Thermal control of spacecraft is accomplished through the optical and thermal properties of the eternal surfaces of the vehicle. The use of thermal control coatings or second surface mirrors on these surfaces ar common methods for managing the overall thermal environment of spacecraft. The proposed low solar absorbance ( ) high emittance ( ET ) thermal control (TC) coating(s) shall be developed ...

High performance military aircraft operating in the hypersonic regime produce large heat loads that can only be managed with endothermic fuels. However, the current knowledge of endothermic chemistry in fuels and its effects over a range of aircraft flight conditions is extremely limited. The proposed Phase I study is aimed at the development of advanced finite rate models to characterize dehydr ...

Wheelchair users are severely restricted from participation in outdoor activities due to the inability to traverse rough and sloped terrain. A novel wheel camber adjustment mechanism for hand powered, all-terrain, wheeled vehicles will be designed and evaluated. This system addresses the central technical issue in achieving high stability in such vehicles. The wheel camber adjustment system all ...

Focal plane arrays (FPAs) are one of the most critical and expensive components in infrared imaging equipment, such as nigh vision, security and surveillance systems. In the device manufacturing processes, at present, it is not possible to determine if the final product is successful until all steps and materials have been incorporated. Since this entire manufacturing process can take up to 12 w ...
