Objective

• From ESMD site this project will investigate
  concepts for Lunar Regolith Excavation equipment
  and propose solutions in the form of completed
  designs and prototypes, using a Systems
  Engineering Approach
• Topic Lunar Regolith Excavation for Oxygen
  Production and Outpost Emplacement
• A standalone Systems Engineering Overview for
  Application of the Process on a Student Project
• Technical Contact and Monitor Rob Mueller,
  Surface Systems Lead Engineer
• Dont give students any design ideas let their
  creative juices flow!

Is Your Situation My Situation?

• I teach a senior project class (capstone
  design), working with a team of students
  assigned to a project. You could be AE, ME, EE,
  etc.
• Minimal or no lecturing students spend their
  time on a project designing and building a
  prototype.
• Faculty guides the student team through the
  design process.
• Project could, but not necessarily, be
  multidisciplinary (single subsystem or many
  subsystems).
• So does this describe your situation??????
• AND
• Are you interested in a NASA capstone design
  project???

6
NASA and Our Situation if you Choose a NASA
Project

• NASA will support student teams with 7K through
  the Space Grant Consortium
• Pick a Project from the ESMD website I chose the
  lunar excavator
• But students need some background information to
  proceed
• Need to know about designing for the lunar
  environment (although they build a prototype for
  use on the earth)
• Need to know about Systems Engineering because
  NASA wants a Systems Engineering Approach
• What Resources are Available????

The Lunar Engineering Handbook and
Webpagehttp//www.eng.auburn.edu/dbeale/ESMDCour
se/

• On Systems Engineering (SE) Provides background
  by a brief, but complete SE guidebook chapter
  (Chapter 3) for a student-team Systems
  Engineering Project.
• Student Friendly, with lots of examples and
  direction meant to simplify a complex process and
  APPLY IT.
• Faculty Friendly faculty lectures for 2 weeks,
  and then guides the process per the process in
  the handbook and webpage (webpage is
  step-by-step).
• Co-authored by a NASA Systems Engineer.
• Strongly influenced by a special NASA SE course
  developed and tested at Univ of Texas Spring 08,
  by a NASA engineer with 20 years experience in
  SE.
• An application example project is presented in
  Chapter 4 on the CubeSat - led by JM Wersinger
• On the Lunar Environment Provides background on
  past and future lunar missions, lunar
  environment, materials and components, thermal
  control, CAE

8
Handbook Content Goals

• Made it student friendly. Cut through the
  clutter that SE literature is full of.
• A linking webpage a chronology for the
  course, basis for the 2 weeks of lectures.
• Meant not to impede student design efforts with
  lots of lectures.
• Faculty should lecture about 2 weeks on SE,
  taking students through the webpage. Students
  read Chapter 3 (Systems Engineering) and CubeSat
  chapter. Quiz Students
• Thereafter faculty guides student team, who are
  referring back to the webpage for guidance.

9
Handbook and Webpage

• Webpage is a Cliff Notes format and project
  chronology, that links to the in-depth content of
  the following chapters
• Chapter 1 Introduction
• Chapter 2 Systems Engineering
• Chapter 3 Systems Engineering Example of a
  Cubesat
• Chapter 4 Systems Engineering Tools
• Chapter 5 The Lunar Environment
• Chapter 6 Component Design and Selection
• Chapter 7 Thermal Control
• Chapter 8 CAE Tools

10
Overview of Chapter 1 Introduction

• Best reference The Lunar Sourcebook, the book
  by Eckhart if you can find it.
• Review of the LPI website with the students.
• Objective Provide background. Excite students.
  Students have little knowledge about what
  happened in early lunar missions, rovers are fun
  and legacy, neat lunar bases, teleoperated and
  autonomous robonaut, chariot.

11
Goals, Objectives and Overview of SE Chapter 2-4

• Best references AU CubeSat Report, NASA SE
  Handbook as a reference, U of Texas Course notes.
• Systems Engineering literature is a mess,
  particularly if you want to apply it and learn it
  quickly. Complex and inconsistent terminology.
• Big questions How to simplify SE, and apply on a
  student project?
• Sought help from experts who have applied it
  Dick Cook, Lisa Guerra, Joe Bonometti, JM
  Wersinger
• It is possible to use these chapter for any SE
  student project!!!

12
A Systematic Process for SE

• The Vee Chart Vee Chart for the lifecycle,
  from A through D
• The 11 SE functions NASA Document GPG7120 Used
  this and description of 11 SE functions
• A Good Example JM Wersingers student report
  that demonstrate SE tools, management structure,
  documentation, requirements, architecture,
  condensed in Chapter 3.

Chapter 5 The Lunar Environment very
important information here

• 1 The Lunar Environment and Issues for
  Engineering Design
• 1.1 Gravity and the Lunar Vacuum
• 1.2 The Lunar Day and Night
• 1.3 Radiation
• 1.3.1 Electromagnetic and Particle Radiation
  (Smithers, 2007 Tribble, 2003)
• 1.3.2 Ionizing Radiation
• 1.3.3 Radiation and Survivability
• 1.4 Surface Temperature
• 1.5 Micrometeoroids
• 1.6 Regolith
• 1.6.1 General Characteristics
• 1.6.2 Other Physical Properties
• 1.6.3 Chemistry
• 1.6.4 Geotechnical and Engineering properties
• 1.6.5 Regolith Simulants
• 1.7 Summary of Lunar Resources
• 1.8 APPENDIX SOIL AND ROVER FORCE CALCULATIONS

17
Chapter 6 Material and Component Selection

• Best Reference Conley (Satellites), Lunar Rover
  pages at LPI
• When designing the excavator, not much guidance
  is available in the literature for lunar
  components, so turned to space engineering
  literature that focused on satellites.
• The Lunar Rover represents legacy, students can
  view a successful lunar product
• I sent students out to do trade studies,
  looking at materials for a bit, conveyor belt,
  support structure, etc.
• Found and listed a number of standards
• Considered fasteners, bearings, motors, power
  components

18
Chapter 8 CAE Tools (demonstration only)

• Modeling and simulating is often used in the
  design phases of Systems Engineering
• Demonstrated a multi-body dynamic simulation of a
  excavator using Dynamic Designer

19
The Webpage System Engineering of an Excavator
by a Multidisciplinary Student Project Team

• In response to and suggested by reviewer
• Rearrangement of order of topics to suit a course
• Content when needed in the course, based on SE
  approach and sequence of SE events as the course
  proceedes.
• Also a kind of Cliff Notes with links to
  content already in other chapters

How to Run Your Class

• Follow the Process on the Webpage
• Pick a mission objective
• Get money in place from Space Grant
• Contact other faculty for multidisciplinary teams
  (although you can run just an ME team with the
  mechanical excavator missions objective)
• Design and build for one or two semesters,
  excavator to mate to KSC vehicle
• Test in bin full of dry concrete.
• Compete???
• Send video to NASA report
