Mounting of infrared (IR) windows on hypersonic vehicles is a critical design issue because of the stresses caused by high temperatures combined with the coefficient of thermal expansion (CTE) mismatch between the window and frame materials. Many applications use elastomeric seals to limit window distortion and stress by allowing for joint flexibility. However, windows and frames operating in this ...

The expected life of satellite Li-Ion batteries is determined by many factors, including thermal considerations, electrode chemistries, orbit and mission life, DOD, and pulse power requirements. First-principles battery model literature pertains primarily to orbital cycling at moderate DOD under isothermal conditions without variable power loads. Knowledge must be extended to encompass wider life ...

Our proposed second order uncertainty (SOU) product is a decision making software solution that addresses the problem of providing accurate and precisely defined decision courses of action (COAs) of complex, time-constrained problems in a fraction of the time required by alternative methods striving to achieve the same level of precision. Complex decision situations can deal with large volume of ...

This Phase II effort will further develop a technique to improve current seeker discrimination and tracking capabilities using a unique particle filter algorithm (PFA) approach. The advancement represents a significant upgrade to current and future seekers facing advanced threats in stressing environments. Quantifiable improvements over many facets of the current approach have been realized during ...

The ISSAC Team propose a novel method to encapsulate legacy models and simulations that allows these components to take advantage of modern, multi-core, multi-processor hardware suites. Encapsulating these legacy codes provides 3 primary advantages to deal with complex systems and systems of systems (Air Force, Navy, Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA) ...

There is a critical need for electrification of transportation systems. The proposed technology enables the development of very high-power density permanent magnet motors, which when coupled to an integrated SiC drive allows for an overall specific power beyond 12 kW/kg. The proposed concept relies on the tight integration of a high-power density dual-rotor permanent magnet motor, high power densi ...

Gyroscopes are found in nearly every airplane, many cars, robots, missiles, and more. The reason for such broad, wide-spread use is simple: gyroscopes are excellent tools for determining rotation, and can be quite sensitive. Improving the sensitivity of optical gyroscopes while also reducing their size and weight has proven to be a significant challenge. To provide a solution, Los Gatos Researc ...

Aerius Photonics is proposing to develop high-power Vertical Cavity Surface Emitting Lasers (VCSELs) and arrays on 4” substrates with an integrated thermal management approach to improve the thermal performance on an entirely wafer-level manufacturing compatible process. This is critical as waste heat and wafer-scale manufacturing approaches are driving factors for performance and costs in a la ...

The goal of this program is to design a lightweight optical bench capable of remaining stable under temperature and moisture changes, while isolating the precision optical array from vibrations such as engine noise and air turbulence. By integrating a customizable periodic stack in the bench, vibrations are attenuated more effectively than commercially available mounts. Additionally, the periodic ...
