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 ...

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 ...

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)

Through previous research and development, the team created a teacher platform that suggests research-based strategies for supporting students with special needs or targeted skill gaps. This project will develop a prototype of a dashboard for teachers to create, access, and track student's Individual Educational Plans (IEPs). At the end of Phase I, in a pilot study with six middle school special e ...

Through a previous grant award from the U.S. Department of Education, researchers developed Read for Success, an intervention designed to stem the summer slide among struggling readers. This project will develop a prototype of Mix Libris, an Augmented Reality (AR) enhanced mobile literacy platform designed to support and motivate grade 3 students in acquiring and improving literacy skills. Mix Lib ...

Through previous grant awards from IES and the National Science Foundation and an ED/IES SBIR award, researchers developed a virtual laboratory with performance-based simulations aligned to Next Generation Science Standards (NGSS) in physical, life, and earth science for middle school, as well as a dashboard to provide teachers real-time formative and summative assessment reports on students doing ...

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 ...

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 ...
