  1. Revisions of the Aerospace Engineering Curriculum at the University of Texas at Austin Dr. Wallace Fowler Department of Aerospace Engineering

  2. What I Will Cover • Emphasis on the Design Sequence • No boring overview of entire curriculum • Limited discussion of “Atmospheric Flight” option • Focus on “Space Flight” option • Highlight Changes Made to Accommodate Integration of Systems Engineering into curriculum

  3. Opportunity Knocked • Fall 2005 - Mike Griffin visited University of Texas at Austin - Strongly suggested including Systems Engineering instruction in engineering programs. • ASE Department Chair invited Ms. Lisa Guerra of NASA ESMD to UT to accomplish this task.

  4. Subsequent Events • 2005-2006 - Dr. Mark Maughmer (Penn State) • Revitalized aeronautical segment of curriculum • Greatly improved Design-Build-Fly efforts • 2006-Present – Ms. Lisa Guerra (NASA ESMD) • IPA from NASA to UT Austin • Extensive Systems Engineering experience • 2006-2007 – Curriculum Revision Opportunity (A RARE Occurrence)

  5. Curriculum Change Constraints • New courses require extra effort – takes time from research • Faculty under pressure to bring in $ (17% of UT funding provided by state) • Curriculum changes need multiple approvals • Old and New Curricula exist together for at least 4 years – increasing number of courses that must be taught

  6. 2006-2008 Curriculum 128 Semester Credit Hours • 30 hours of Math & Science • 24 hours of Humanities/Social Science/Liberal Arts • 22 hours of Basic Engineering Topics • 14 hours of Aerodynamics/Propulsion/Fluids/Flt Mech • 6 hours of Electric Circuits / Controls • 16 hours of Structures/Materials/Measurements • 3 hours of Orbital Mechanics / Attitude Dynamics • 6 hours of Technical Electives • 7 hours of Option Area Courses (Atmospheric / Space)

  7. 2008-2010 Curriculum 128 Semester Credit Hours • 30 hours of Math & Science • 24 hours of Humanities/Social Science/Liberal Arts • 23 hours of Basic Engineering Topics • 14 hours of Aerodynamics/Propulsion/Fluids/Flt Mech • 6 hours of Mechatronics / Controls • 9 hours of Structures/Materials/Measurements • 3 hours of Orbital Mechanics / Attitude Dynamics • 6 hours of Technical Electives (Six 1 credit projects) • 13 hours of Option Area Courses (Atmospheric / Space)

  8. Major Changes in Curriculum • Added 1 hour to Engineering Computation • Moved Technical Writing to fourth semester • All students take Compressible Aerodynamics • Electric Circuits  Mechatronics • Thermodynamics  Thermodynamics & Heat Transfer • Added up to six one-hour project credits • Basic Orbital Mechanics  Intro to Orbital Mechanics and Attitude Dynamics • Technical Areas increased from 7 to 13 hours

  9. Space Flight Technical Area Changes • Advanced Orbits / Attitude Dynamics  Attitude Dynamics (3 hours) • Added Advanced Orbital Mechanics (3 hours) • Orbital Computations Lab  Spacecraft Systems Modeling Lab (1 hour) • Added (Space) Systems Engineering (3 hours) • Modified Capstone Spacecraft/Mission Design (3 hours )

  10. S/C Systems Modeling Lab • Replaces Space Applications Lab • Replaced material goes into Advanced Orbital Mechanics course • Focus on Spacecraft Subsystems • Working Knowledge of Subsystems • Preliminary Sizing • Estimating Performance • Modeling and Simulation Techniques

  11. One Hour Project Credits • Up to six one-hour credits (one per semester) for non-class related project participation. • Satellite build projects • Design – Build – Fly Projects • Student participation in research projects • Hours accumulate along with COOP hours for technical elective credit. • Previously, students received no formal credit for these efforts.

  12. Satellite Design/Build Projects • Air Force NanoSat Program • Nano Satellite (FASTRAC) • Dual Satellites (Texas2step) • NASA/TAMU/UT Project • Dual Satellites – Autonomous Rendezvous (Paradigm) • WIPSat Project • Wireless Internet Protocol Communications Information from the Systems Engineering Course has already strengthened these efforts

  13. 2006-08 Design Sequence • Structural Design and Testing – 4 hrs • Primarily a structural testing project course • Spacecraft/Mission Conceptual Design – 3 hrs • Team design projects course taught only in Fall • 60 students in class in Fall 2007/Six teams • Ideal is 5-7 students per team • Limited “systems engineering” instruction in class • Focus on getting a project done

  14. 2008-2010 Design Sequence • Space Systems Engineering – 3 hours • Replaced Structural Design and Test • Pilot Class in Spring 2008 • Required in 2008-2010 Curriculum (Offered regularly beginning Fall 2008) • Prerequisite for Spacecraft/Mission Design • Spacecraft / Mission Design – 3 hours • Project types will change • Students will be better prepared

  15. Student Concept Awareness • Project Life Cycles • Project Scoping • Concepts of Operations • System Hierarchy • Requirements • Functional Analysis • Trade Studies • Design Margins • Costs / Risks / Verification and Validation • Technical Reviews

  16. Expectations • Better understand the “whole picture” • Aware of the importance of subsystems and interfaces between them • View from multiple perspectives • Understand the importance of requirements • Understand the concept of “unintended consequences” • Earlier focus on problem identification and solving

  17. September 2008 • Transition Period • Systems Engineering • Required for Space Flight Option (roughly half of students in department) • Spacecraft/Mission Design • Taught both Fall and Spring  Smaller classes • Have 4 students with Systems Engineering background
