Design Space Exploration of the Hall Effect Thruster for Conceptual Design

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Design of a Miniaturized Hall Thruster for Microsatellites

Microsatellite technology has become increasingly popular in recent years as it can offer significant cost savings, higher reliability, and is generally more affordable for a large variety of commercial applications. Since many microsatellite missions require considerable propulsion capabilities, miniaturization of the propulsion subsystem is critical in the design of most miniature spacecraft....

Design Knowledge Exploration for the Conceptual Design of Tire Contours

The importance of the rule of simulation at a conceptual design stage is pointed out recently. The methodology using multi-objective design optimization and data mining, which is called MODE (Multi-Objective Design Exploration), is helpful to find out design knowledge. In this study, we show that the design knowledge found by MODE is fruitful for decision making at a conceptual design stage of ...

Bismuth Hall Thruster I: Simulation-suggested Design and Performance

A two-dimensional radial-axial hybrid simulation of the xenon-fueled Stanford Hall Thruster has been adapted to model a bismuth-fed thruster with varying channel geometry. The simulation treats the electrons as a quasi-one-dimensional fluid and the neutrals and ions as discrete superparticles advanced using a particle-in-cell (PIC) approach. Since experimental data of the electron cross-field m...
