2017 Projects and Teams

Attitude of Small Satellites Under High Thrust

Mentors: Nick Dallmann (P-21) & Bryce Tappan (M-7)

Students: Andrea Martinez, Nicholas Stull, Gregory Taylor

A very high thrust solid rocket system has been developed at LANL.  There is interest in employing this technology in small satellites.  However, the rocket would impart a large impulse over a very short timeframe to a vehicle with low moment of inertia.  Even the slightest misalignment between the thrust vector and the vehicle center of mass will impart a torque and integrated angular momentum in excess of the satellite’s attitude control system capabilities.  Traditionally, this type of problem would be solved with a combination of additional thrusters, active thrust vectoring, and/or additional vent paths.  However, due to the very small size and very high level of impulse, these approaches are not likely adequate.  High temperature valves, gimballing actuators, etc. are large and would likely add significant weight cutting into the mass fraction and effective performance of the system.  The students working this project will need to become familiar with what has been done to solve this problem in the past and why those approaches are inadequate for this application.  Then, the students will need to think outside the box to brainstorm and then analyze new solutions.  See the link to an animation with LANL’s CubeSat and motor.  http://www.lanl.gov/discover/news-release-archive/2016/October/10.13-rocket-motor-concept-could-boost-cubesat-missions.php

Hanford Tank Solid Waste Characterization and Removal

Mentors: Paul Dixon (SPO-CNP) & John Ahern (MET-1)

Students: Jacob Stinnett, Brendon Parsons, Elizabeth Phillips

There are 177 underground high-level waste storage tanks at Hanford. A significant number of these tanks are known to leak or be of unknown structural integrity.  The current method of tank waste retrieval includes various permeations of using liquid to slurry waste and pump it to the treatment facility.  This method utilizes large amounts of water and in known leaker tanks this presents risk of waste release to the environment. This makes the current water based waste removal systems difficult or impossible to use to remove the waste in many of tanks.  A significant improvement to the waste removal process for these tanks could be realized if the waste was dry mined using small robotic based mining techniques.  Development of a durable  robotic mining capability is needed.  In addition, if there was a way to stabilize the waste in the tank before it is mined out for instance using something like a 3D printing technique to make an intermediate waste form then fine particulate/dust control could be minimized making this mining technique safer.   If this methodology were employed, it is likely that the mined waste could be placed in compliant shipping/disposal containers and directly disposed at an alternative disposal facility and not have to be made into glass logs.  Using robotic mining and avoiding liquids in retrieving Hanford tank waste will lead a significant reduction in the potential for contaminated waste release to the environment and it will reduce exposure to the workers.  The goal of this work is to explore and develop potential techniques to remove the waste from the Hanford Tanks in such a manner that it can be transported safety.  Furthermore, we anticipate that part of this project may involve characterization of the waste to aid in the processing.

Characterizing the Seismic Activity/Response of Planets Remotely from Space

Mentors:  Reinhard Friedel (Center for Space and Earth Science) & David Mascareñas (Engineering Institute)

Students: Tiffany Desjardins, Angelika Leskovskaya, Ryan McCombe

Understanding the seismic response of planets is often of interest.  This information can be used to help determine the geophysical composition of a planet or moon.  Similarly, asteroseismology focuses on developing techniques for inferring the internal structure of stars by considering how waves propagate inside the stars.  By analyzing small variations in the light that is emitted by stars the natural frequencies of vibration can be measured.  In the last few years there have been significant breakthroughs in image processing techniques for estimating the natural frequencies and full-field mode shapes of structures using only a video camera.  The literature suggests these techniques have the potential to be very sensitive.  The goal of this work is to explore the realm of the possible with respect to performing techniques such as elastic wavefield tomography of planets and moons using only imagers placed on a spacecraft.  The team will explore what level of sensitivity could be achieved by such techniques, they will explore the possibility of novel imagers to make remote seismographic characterizations that have not been considered in the past, and they will propose a path forward on future engineering/science work that can enable the next generation of space-based seismology for inferring the internal structure of planets.

Efficient Nearest Neighbor Communication in Application Specific Integrated Circuits for Physics

Mentors:  Nandu Santhi (CCS-3) & Stephan Eidenbenz (Information Science & Technology Institute)

Students: Spencer Johnson, Rose Long, Benjamin Winter

Custom hardware architectures in the form of application specific integrated circuits (ASIC) can potentially accelerate physics applications several orders of magnitude. A common communication pattern in many of these architectures involves exchanging information with so called nearest neighbors of physical entities such as atoms. However, limited routing resources in current planar semiconductor technologies means that, we can physically interconnect to only a few neighbors at a time. Under such conditions, a way to achieve an all to all pattern is to let the communications be time multiplexed across available metal routes - which means that the overall architecture has a reduced performance per clock cycle. In essence, custom architectures have to either limit the number of neighbors to a small constant or, if all to all communication is a must, then severely limit the achievable hardware speedups. The objective of this project is to come up with novel solutions to this nearest neighbor communication problem, so that custom integrated circuits for typical physics problems such as the Ising problem, molecular dynamics and KMC may achieve the highest possible theoretical speedups in practice.
