This course offers a detailed look at reusable launch vehicles, how they function, insight into limitations and opportunities for the future. Technology requirements and design challenges are addressed. Special payload accommodations and interfaces are discussed. Material includes a survey of the international inventory of potential contender reusable designs and appropriate rocket engines. Essential systems and subsystems are defined and explained. Case studies addresses design requirements and constraints for a fully reusable vehicle concept. Partially reusable systems are also considered, such as the recoverable Falcon 9 first stage. Proposed recovery and recycling operations are presented. The course includes a discussion of suborbital reusable systems such as Virgin Galactic and other contenders. Discussions include the impact of FAA licensing, spaceport selection criteria and novel applications of commercial and government reusable vehicles. Attendees are exposed to the latest developments throughout the reusable launch vehicle world and given a complete survey of concepts and design developments.
Each attendee receives a copy of the presentation and reference materials.
