A Comparative Study of Simulations and Experimental Testing on Screw-Propelled Vehicle in a Lunar Simulant

Mentor: Hamid Marvi
FURI: Spring 2019

Screw-propelled vehicles are effective in difficult environments on earth; however they have not been properly investigated for space application. A better understanding of the terra-mechanics of dirt in lesser gravities is necessary to understand how a rover will move and interact with its surroundings on different planets or smaller bodies. Through experimentations and Discrete Element Modeling (DEM) simulations, a better understanding of how a screw-propelled vehicle moves in a lunar simulant called Black-Point 1 (BP-1) was developed. By developing and verifying accurate simulations of this environment, rover designs can be tested in different scenarios before even leaving earth.

A Comparative Study of DEM Simulations with Testing of a Screw-Propelled Vehicle in BP-1

Mentor: Hamid Marvi
FURI: Fall 2018

Space exploration is a very costly yet important endeavor. Screw-propelled vehicles are often used to overcome difficult terrain on earth. However, they have not been fully explored for space application. The primary goal of this research is to understand how a screw-propelled vehicle behaves in extraterrestrial environments through the testing of a rover design in a lunar stimulant known as Black Point 1 (BP-1). Experimental results were compared to simulations created using DEM (Discrete Element Modeling) software. By creating accurate simulations, vigorous testing can be done before spending millions of dollars on the construction and launch of a design.
