This course presents a systems perspective of structural engineering in the space industry. Originally based on the instructor's book, Spacecraft Structures and Mechanisms: From Concept to Launch, this course has evolved and been improved continuously since 1995.

If you are an engineer involved in any aspect of spacecraft or launch–vehicle structures, regardless of your level of experience, you will benefit from this course. Subjects include functions, requirements development, environments, structural mechanics, loads analysis, stress analysis, fracture mechanics, finite–element modeling, configuration, producibility, verification planning, quality assurance, testing, and risk assessment. The objectives are to give the big picture of space-mission structures and improve your understanding of

• structural functions, requirements, and environments
• how structures behave and how they fail
• how to develop structures that are cost–effective and dependable for space missions

Despite its breadth, the course goes into great depth in key areas, with emphasis on the things that are commonly misunderstood and the types of things that go wrong in the development of flight hardware. The instructor shares numerous case histories and experiences to drive the main points home. Calculators are required to work class problems.

Each participant will receive a copy of the instructors’ 850-page reference book, Spacecraft Structures and Mechanisms: From Concept to Launch.

Instructors:

Tom Sarafin as worked full time in the space industry since 1979, at Martin Marietta and Instar Engineering. Since founding Instar in 1993, he has consulted for DigitalGlobe, AeroAstro, AFRL, and Design_Net Engineering. He has helped the U. S. Air Force Academy design, develop, and test a series of small satellites and has been an advisor to DARPA. He is the editor and principal author of Spacecraft Structures and Mechanisms: From Concept to Launch and is a contributing author to all three editions of Space Mission Analysis and Design. Since 1995, he has taught over 150 short courses to more than 3000 engineers and managers in the space industry.

Poti Doukas worked at Lockheed Martin Space Systems Company (formerly Martin Marietta) from 1978 to 2006. He served as Engineering Manager for the Phoenix Mars Lander program, Mechanical Engineering Lead for the Genesis mission, Structures and Mechanisms Subsystem Lead for the Stardust program, and Structural Analysis Lead for the Mars Global Surveyor. He’s a contributing author to Space Mission Analysis and Design (1st and 2nd editions) and to Spacecraft Structures and Mechanisms: From Concept to Launch. He joined Instar Engineering in July 2006.

11. Designing for Producibility
    Guidelines for producibility, minimizing parts, designing an adaptable structure, designing to simplify fabrication, dimensioning and tolerancing, designing for assembly and vehicle integration

12. Verification and Quality Assurance
    The building-blocks approach to verification, verification methods and logic, approaches to product inspection, protoflight vs. qualification testing, types of structural tests and when they apply, designing an effective test

13. A Case Study: Structural design, analysis, and test of The FalconSAT-2 Small Satellite

14. Final Verification and Risk Assessment
