Rocket Propulsion 101
This three-day course is based on the popular text Rocket Propulsion Elements by Sutton and Biblarz. The course provides practical knowledge in rocket propulsion engineering and design technology issues. It is designed for those needing a more complete understanding of the complex issues. The objective is to give the engineer or manager the tools needed to understand the available choices in rocket propulsion and/or to manage technical experts with greater in-depth knowledge of rocket systems. Attendees will receive a copy of the book Rocket Propulsion Elements, a disk with practical rocket equations in Excel, and a set of printed notes covering advanced additional material.
