The goal of the project is to develop a handheld instrument that detects, identifies, and categorizes radioactive sources based on gamma, thermal-, and fast-neutron signatures. Existing radioisotope identification devices (RIIDs) are typically biased toward gamma spectroscopy; some instruments may use an additional inefficient neutron counter in form of a He-3 tube. The recent development of mat ...

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 ...

Triton Systems, Inc. proposes to develop a method for efficiently running federated simulations of atmospheric and orbital rocket flight. Tritons proposed method will be able to get information between time steps without the need for interpolation and will significantly reduce the computational time needed to run Federated simulations.Approved for Public Release | 18-MDA-9522 (23 Feb 18)

CU Aerospace (CUA) and team partners San Jose St. University (SJSU) and Lockheed Martin Space Systems Company (LMSSC) propose to develop a robust epoxy resin regenerator capable of improving cryocooler efficiency by more than 30%, and to design an enhanced compressor motor capable of improving the cryocooler efficiency by more than 20%. LMSSC manufactures a space cryocooler that already meets most ...

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 ...
