Concurrent engineering of space missions

Caution, these contents corresponds to the coursebooks of last year

ENG-411 / 2 credits

Language: English

Withdrawal: It is not allowed to withdraw from this subject after the registration deadline.

Summary

The main objective of this course is to teach the students the fundamentals of concurrent engineering for space missions and systems. The course is built around a similar framework to that of the European Space Agency's (ESA) Concurrent Engineering Challenge.

Content

Note: Up to date information about this course can be found in https://cdf.epfl.ch/en/eng411

Students are teamed up to design a space mission together in an intensive 2-week-long workshop, using the tools & process of Concurrent Engineering. During the course they will be at all times supported by experts from eSpace. This is a cooperative challenge, meaning team members will share progress at the end of every day and collaborate to design a mission or system. Course ends with a final presentation of the mission/system designed by each team. By the end of the course students shall become familiar with the foundation, benefits, and application of concurrent engineering practices when applied to solving complex engineering problems.

Introduction:

What is concurrent engineering?
Introduction to common concurrent engineering practices and tools.
Target mission design: mission overview, science objectives, and high-level requirements.

Practical engineering of a space mission:

Primer on the space environment & spacecraft subsystems. Students form a team and are individually assigned to a given subsystem based on their competencies & interests. The involved disciplines include: structures & mechanisms, configuration, power, thermal, AOCS, propulsion, trajectory analysis, communication & data handling, and systems engineering.

Concurrent & Systems Engineering techniques in action:

Real-time concurrent engineering processes, including: mission phases & modes definition, identification & resolution of key design trade-offs; design budgets; product tree; design iterations; preliminary subsystem design; trades between subsystems.

Engineering teamwork:

Structured, intensive collaboration within and between engineering disciplines to rapidly design, in a realistic environment with tooling. Leadership & interpersonal skills, including presentations to peers & expert review, and their impact on design process success.
