Launch Vehicle Systems – Reusable
This course provides the practical knowledge to understand the issues of costs, performance, technology, operation and utility of reusable launch systems. The seminar is designed for engineers, decision makers and managers of current and future projects needing a better understanding of the complex issues involved in the optimization of reusable launch vehicles. The seminar describes the choices and consequences of options facing those seeking to improve space transportation through decreased dependence on expending launch vehicle hardware. You will learn a wide spectrum of problems and solutions to reusable launch vehicle technology and how the choices stack-up against current expendable vehicle systems.
The seminar is taught from the point-of-view of reusable launch vehicle decision makers. What do you need to know to achieve a practical and cost-effective reusable launch vehicle, given performance reliability, safety and cost trade-offs? What do you need to know to make the proper decisions from propellant selection and architecture to the level of new technology needed to achieve the desired degree of success? The similarities, and differences between expendable and reusable vehicle systems, design and performance are compared and explained to help understand the optimum launch vehicle design.
Attendees will receive a complete set of printed notes. These notes will be an excellent future reference for current trends to the state-of-the-art in reusable launch vehicle modeling, design, development, operations and decision criteria.
