Free Vibration of a Panel Supported by a Shear Compliant Tow Flexure HingeEmbargoed
Jan 8, 2024
Juan Mejia-Ariza, 2024, "Free Vibration of a Panel Supported by a Shear Compliant Tow Flexure Hinge", https://doi.org/10.48577/jpl.O3Q2PJ, American Institute of Aeronautics and Astronautics, JPL Open Repository
Elastically deformable hinges or deployable booms commonly follow architectures with face-skin layers only, cutting out the core to facilitate folding. This significantly reduces the shear stiffness of the hinge, which might reduce the first resonance frequency of the structure....
High-Throughput Viscoelastic Testing for Composite Laminates
Jan 8, 2024
Serena Ferraro, 2024, "High-Throughput Viscoelastic Testing for Composite Laminates", https://doi.org/10.48577/jpl.N6Y2K4, 2024 AIAA Science and Technology Forum and Exposition, JPL Open Repository
Composites are excellent material candidates for large deployable spacecraft structures. Prior to deployment in space, these structures are stowed in the furled configuration for prolonged periods. The mechanical response of composite laminates used in these structures is greatly...
Starburst: A Concept for a New Deployable Structure Architecture
Jan 8, 2024
Jonathan Sauder, 2024, "Starburst: A Concept for a New Deployable Structure Architecture", https://doi.org/10.48577/jpl.M8DFZC, AIAA SciTech 2024, JPL Open Repository
This paper presents Starburst, a novel architecture for deployable structures that has the potential to revolutionize the way rigid panel deployables are approached in future missions. The core elements of the Starburst architecture consist of rigid segments, high strain rods for...

Magnetically Shielded Miniature Hall Thruster: Flight Qualification, LIF, and Krypton Performance
Jan 8, 2024
Jacob Simmonds, 2024, "Magnetically Shielded Miniature Hall Thruster: Flight Qualification, LIF, and Krypton Performance", https://doi.org/10.48577/jpl.KJ2VYG, AIAA SciTech 2024, JPL Open Repository
Experimental and theoretical studies of magnetic shielding of Hall thrusters have shown significant enhancement of lifetime through reduced erosion of the thruster discharge channel. This enabling technology provides the capability for Hall thrusters to operate in deep space miss...
To Boldly Go Where No Robots Have Gone Before – Part 3: Characterizing the Performance of Screw Propulsion for Robust Surface and Subsurface Mobility of EELS on Highly Unknown Terrains
Jan 8, 2024
Eloise Marteau, 2024, "To Boldly Go Where No Robots Have Gone Before – Part 3: Characterizing the Performance of Screw Propulsion for Robust Surface and Subsurface Mobility of EELS on Highly Unknown Terrains", https://doi.org/10.48577/jpl.JHDWAY, AIAA SciTech 2024, JPL Open Repository
The Extant Exobiology Life Surveyor EELS system is a snake-like robot, with active skin screw propulsion, composed of a series of repeating segments, each housing both the actuation and propulsion mechanisms. By displaying versatile adaptability to different types of terrains, th...
Performance dryout limits of oscillating heat pipes: a comprehensive theoretical prediction from an analytical approach and experimental determination
Jan 8, 2024
Scott Roberts, 2024, "Performance dryout limits of oscillating heat pipes: a comprehensive theoretical prediction from an analytical approach and experimental determination", https://doi.org/10.48577/jpl.W4KRBM, 2024 AIAA SciTech Forum and Exposition, JPL Open Repository
The performance limits of oscillating heat pipes (OHP) have been the subject of research in recent years, in order to understand their limitations and allow their broad application in the aerospace field. The present work describes the experimental determination of the performanc...
Multiphysics Level-Set Topology Optimization of a Rover Chassis for Extreme Cold Environments
Jan 8, 2024
Alex Guibert, 2024, "Multiphysics Level-Set Topology Optimization of a Rover Chassis for Extreme Cold Environments", https://doi.org/10.48577/jpl.8ROITN, AIAA SciTech 2024, JPL Open Repository
Topology optimization is applied to design a lunar rover chassis to reduce thermal losses while maintaining adequate structural strength and stiffness. Space missions in extreme cold environments, such as the permanently shadowed regions (PSR) of the moon, are designed to reduce...
