RESEARCH PROJECTS

From 2019-2022, CAM-STAR has been working on the following three main projects, focusing on ‘Devices and tools enabled by Advanced Manufacturing (AM) for Space Technology and Applied Research’. All three projects are interconnected to each other by complementary niche areas.

Project 1 Passive Thermal Control

Faculty Team: Jiajun Xu (UDC), Pawan Tyagi (UDC), Angel Alvarez-Hernandez (JSC), Mike Ellis (ACT), Calin Tarau (ACT), Bao Yang (UMD)

UDC team led by Dr. Xu and external collaborators (including Advanced Cooling Technologies, University of Maryland, and NASA Johnson Space Center) have been working collaboratively.

Project 2 Thermal Protection System

Faculty Team: Pawan Tyagi(UDC), Kate Klein(UDC), Jiajun Xu(UDC), Devdas Shetty(UDC), Angel Alvarez-Hernandez (JSC), Mike Ellis (ACT), Calin Tarau (ACT), Bao Yang (UMD)

UDC team led by Dr. Tyagi and external collaborators (including Advanced Cooling Technologies, University of Maryland, and NASA Johnson Space Center) have been working on the task 1 in which methods to process the surface finishing of AM produced parts is being developed

 

Project 3 ISRU

Faculty Team: Lei Wang (UDC), Qiushi Chen (Clemson), Jiajun Xu (UDC), Kamlesh Lulla (JSC)

UDC team led by Dr.  Wang and external collaborator at Clemson University, have been working on the task 1 in which they are working on how to formulate a bio-inspired energy-efficient drilling method and develop a discrete element model for evaluating the mechanism for interaction of drilling tool and the lunar regolith (granular materials). The technical lead has engaged three UDC students to work on this project.

CAM-STAR also has the following two other space-related projects, as shown below.

Project Title:

Investigation of the Effect of Cross Section & Aspect Ratio on Heat Transfer Performance of Nanoemulsion Flow in AM Microchannel Heat Exchangers.

Design and Development of an AM Geothermal Heat Exchanger for Easy Installation under Ground Surface.

 

Moving along from 2022, in addition, the team with expanded faculty researchers have started to work on newly proposed projects. The new projects in four main research thrusts are listed below which are aligned with NASA mission directorates in Space Technology Mission Directorate and Human Exploration (STMD) & Operations Mission Directorate (HEO).
