Threaded fastening systems in vibrating environments require a secondary locking feature, augmenting primary locking provided by an applied preload, to prevent vibration-induced loosening. The secondary locking feature can be mechanical, prevailing torque-type, or an adhesive. Self-locking nutplates and inserts are often more expensive than adhesives, require retorquing or on-torque adjustments, a ...

Physical Sciences Inc. has successfully demonstrated the operational capability of a filament wound composite case designed to mitigate against slow cook-off, fast cook-off, bullet and fragment impact threats for solid rocket motor (SRM) systems. The implemented manufacturing, quality control and assurance processes enable production of small and large diameter motors to satisfy strategic and tact ...

This Phase II SBIR project will advance the technical readiness level (TRL) of our Phase-I-demonstrated strategy for mitigating radiation damage in GaSb/InAs Type II Strained-Layer-Superlattice (SLS) long-wave infrared (LWIR) detectors. Our mitigation strategy will be optimized for detectors to be deployed in interceptor seeker systems that will be exposed to radiation in the near-Earth orbital en ...

Physical Sciences Inc. (PSI) proposes to utilize a ground-based simulation facility based upon its patented FAST technology to obtain critical data necessary to validate and extend the capabilities of the MDA’s high altitude plume code, SOCRATES-P, to model plume signatures with high fidelity. In Phase I PSI demonstrated the model validation approach by measuring the velocity dependent cross sec ...

QuNav proposes to validate and prototype a TRansform-domain INS Mechanization and Algorithmic Correction (TRIMAC). TRIMAC utilizes joint time/frequency domain processing of inertial sensor data in order to mitigate INS drift in the absence of external navaids (such as GPS). Frequency-domain implementation is particularly designed to improve the inertial performance in high-vibration missile enviro ...

Large federated simulations are inherently complex to design and execute effectively to meet experiment objectives. When running a series of computationally expensive simulations, simulation engineers need to quickly analyze critical events of interest (e.g., time of detection) without being inundated with GBs of irrelevant data. Unfortunately, many critical events are sporadic, so to ensure that ...

Data logging of complex simulations can easily overwhelm computer resources or risk losing critical data. Knowing what data is most relevant while simultaneously minimizing collection resources, is extremely challenging.Intelligent Dynamic Data Logging (IDDL) senses run-time data volume, considers scenario objectives, and monitors system performance to record only the most relevant data. It maximi ...

MDA’s Objective-Simulation-Framework (OSF) is a crucial infrastructure for improving the nation’s BMDS. Albeit successful in enabling high-quality ground tests, OSF’s distributed simulations are hampered by hefty data transmissions that could consume up to 50% of the time in a single run. To address this problem, and with the ultimate goal of substantially accelerating OSF tra ...

Missile seekers are precision guided munitions that are a key element of modern defense systems.Seekers using laser guidance or imaging require IR-transparent protective windows domes.One of the most challenging applications is in endo-atmospheric interceptors. The ultimate achievable performance of missile seekers under such extreme conditions is limited by the available infrared window materials ...

CeraNova conformal spinel windows that will provide enhanced performance over traditional, flat sapphire windows.Conformal spinel windows will maintain the curvature of the nose cone and will thus eliminate aerodynamic hot spots caused by flat surfaces.CeraNovas transparent ceramics and experience in manufacturing conformal optics will be leveraged to enable design and fabrication of a conformal w ...
