The Department of Defense uses large-scale high-resolution federated simulations to propagate rocket vehicle trajectories. Runge-Kutta methods have served as a de-facto standard while conducting such simulations. However, there are several challenges while using Runge-Kutta methods for this task. Firstly, there should be exact time-step matching between federates, otherwise the states have to be i ...

Magnesium alloys have 35% lower density compared to aluminum, with improved temperature stability compared to high strength aluminum.They can also be fabricated with minimum gauge thicknesses considerably thinner than fiber composites, and are weldable, with much higher impact resistance.Traditional magnesium alloys, however, have had lower strengths than more developed aluminum alloys.Powder meta ...

The Iris Technology team which also include Northrop Grumman Aerospace Systems (NGAS) and the University of Wisconsin, is attacking the problem of high-efficiency, low-volume, space-qualified cryocooler systems.The team has a firm starting point by leveraging the Northrop Grumman Microcryocooler and the Iris Technology mLCCE (Miniature Low Cost Control Electronics).TMU enhancement will start with ...

The proposed work will incorporate the newly released software into the signature analysis workflow. Extensions of the US3D flow solver will include improvements to the decoupled implicit solver to robustly and efficiently handle reacting flow. Trajectory specification, conjugate vehicle heating, and ablation with surface recession will be enabled through use of a Trajectory Ablation & Shape Chang ...

The premise of this work is that the main barrier to optimizing battery performance lies in understanding the relationship between bulk solids and particle flow properties and the flow into the die.Our hypothesis: an increase in quality battery production can be achieved if product preparation can be optimized and/or the die filling process controlled.Since die compression is mainly one-dimensiona ...

In a pilot study effort in 2013, the Secretary of Defense for Manufacturing and Industrial Base Policy (ODASD (MIBP)) developed a methodology that goes beyond legacy reactive and program-centric frameworks for assessing industrial base risk. This proposed effort leverages the pilot studys work with the fragility and criticality (FaC) assessment to develop a predictive and proactive tool to assist ...

Space Micro and partner institution Arizona State University propose to design and prototype a Programmable Multi-Frequency Transmitter (PMFT) that is compliant with both the Kill Vehicle Modular Open Architecture (KVMOA) and Space Telecommunications Radio System (STRS) standards. The KVMOA maximizes reuse of components and system designs and reduce total ownership costs. The STRS standard allows ...

An advanced hit detection technology is needed for missile testing that can report impacts at hyper-velocities and at multiple hit locations.We present a technology with an attractive cost and performance that leverages decades of hit technology experience and utilizes existing technologies developed under previous efforts.Our technology offers a low latency non-interpolated direct indicator of mu ...

FreEnt Technologies, Inc., along with A2Z Innovations, Inc. (A2Z) and the University of Alabama in Huntsville (UAH) are teaming together to design and develop a High-Speed Simultaneous Multiple Object Detection (HS-SMOD). The HS-SMOD system uses a simple but innovative technique of a passive fiber-optic grid and opto-electronic detectors to measure the initial and subsequent hit points of extremel ...

Future, large footprint weapon systems can benefit from a multi-frequency telemetry system that provides support for multiple bands and various Advanced Range Telemetry (ARTM) waveforms. The overarching objective of the proposed research is to develop a low power, miniaturized, multi-frequency transmitter for intelligent missile flight test applications. The system will remotely relay telemetry da ...
