Satellite Liquid Propulsion Systems Training Course – Hands-on
Liquid Rocket Propulsion Systems have been used on near-earth orbiting satellites and deep space interplanetary missions for the last five decades. This four-day Satellite Liquid Propulsion Systems Training course provides a comprehensive treatment of all types of spacecraft pressure-fed liquid propulsion systems including (1): Monopropellant hydrazine and hydrogen peroxide systems, (2): Bipropellant MMH/NTO systems, and (3): Dual Mode Hydrazine/NTO systems. This hands-on, application-oriented course covers the fundamentals and applications of liquid rocket propulsion to satellite design and operation for both spinning and three-axis configurations. The course includes propulsion Trade studies, Design and analyses, Component sizing and selection, Propulsion manufacturing, integration, and cleaning, System testing, Propellant loading and pressurization, Vertical and horizontal launch processing, Launch, Mission operations, On-station operations and Final de-orbiting of the satellite. Each student will receive a copy of complete set of lecture notes and the AIAA papers by the instructor.
Satellite Liquid Propulsion Systems Training Course – Customize it
- We can adapt this training course to your group’s background and work requirements at little to no added cost.
- If you are familiar with some aspects of this training course, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the Satellite Liquid Propulsion Systems Training around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the training course in manner understandable to lay audiences.
