ATI's Space Mission Structures: From Concept to Launch course
|
Summary:
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.

Course Outline:
- Introduction to Space-Mission Structures
Structural functions and requirements, effects of
the space environment, categories of structures,
how launch affects things structurally,
understanding verification, distinguishing between
requirements and verification
- Review of Statics and Dynamics
Static equilibrium, the equation of motion, modes
of vibration
- Launch Environments and How Structures
Respond
Quasi-static loads, transient loads, coupled loads
analysis, sinusoidal vibration, random vibration,
acoustics, pyrotechnic shock
- Mechanics of Materials
Stress and strain, understanding material variation,
interaction of stresses and failure theories, bending
and torsion,
thermoelastic effects, mechanics of composite
materials, recognizing and avoiding weak spots in
structures
- Strength Analysis
The
margin of safety, verifying structural integrity is
never based on analysis alone, an effective process
for strength analysis, common pitfalls, recognizing
potential failure modes, bolted joints, buckling
- Structural Life Analysis
Fatigue, fracture mechanics, fracture control
- Overview of Finite Element Analysis
Idealizing structures, introduction to FEA,
limitations, strategies, quality assurance
- Preliminary Design
A process for preliminary design, example of
configuring a spacecraft, types of structures,
materials, methods of attachment, preliminary
sizing, using analysis to design efficient structures
- Avoiding Problems with Loads and Vibration
Introduction to passive loads control, adding
passive damping, isolating frequencies, isolating
the spacecraft from the launch vehicle
- Improving the Loads-Cycle Process
Overview of loads cycles, managing math models, integrating
stress analysis with loads analysis
- 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
- 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
- A Case Study: Structural design, analysis, and test of The FalconSAT-2 Small Satellite
- Final Verification and Risk Assessment
Overview of final verification, addressing late
problems, using estimated reliability to assess risks
(example: negative margin of safety), making the
launch decision
Testimonial:
