Spacecraft Structural Design

Learning Outcomes

Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

• Calculate loads on the spacecraft structural elements
• Perform a high level spacecraft structural analysis
• Understand the mechanical design requirements quoted in launcher user manuals
• Select appropriately the structural parameters to meet the requirements

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• The basic principles of the spacecraft structural design process
• The development of the spacecraft structural design, starting from the definition of the structural requirements to the final structural test campaign

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Solve problems systematically
• Study and learn independently

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Gain an awareness of structural analysis approaches and testing methods for spacecraft design

Learning Outcomes

Having successfully completed this module you will be able to:

• M1 As part of the final assessment and module quizzes the student must apply a comprehensive knowledge of mathematics, statistics and engineering principles to the solution of complex spacecraft structural problems. Much of the knowledge will be at the forefront of spacecraft engineering and informed by a critical awareness of new developments and the wider context of Aerospace engineering. M2 As part of the final assessment the student must formulate and analyse complex problems to reach substantiated conclusions. This will involve evaluating available data using first principles of mathematics, statistics and engineering principles, and using engineering judgement to work with information that may be uncertain or incomplete, discussing the limitations of the techniques employed. M3 As part of the final assessment the student must select and apply appropriate computational and analytical techniques to model complex spacecraft structural problems, discussing the limitations of the techniques employed. M6 As part of the final assessment the students must apply an integrated or systems approach to the solution of complex problems. M13 As part of the final assessment and module quizzes the student must select and apply appropriate materials, equipment, engineering technologies and processes, recognising their limitations.
