Introduction to Orbital Mechanics & Lunar Mission Planning
LOCATION: YOUR FACILITY
DURATION: THREE DAYS
COURSE NO.:2020
COURSE SUMMARY
This professional course covers basic orbital mechanics and includes an introduction to the concepts needed to design a trip from the earth to the moon. The course also includes historical information about the development of classical orbital mechanics, modern astrodynamics and the Apollo lunar missions. Two-body and multi-body orbital dynamics will be discussed, especially as they apply to lunar missions. In addition to classical propulsive maneuvers based on chemical rockets, electrical propulsion will be introduced as well, to include a discussion of optimal steering control laws for continuous-thrust space transfers. Recent examples of electric space propulsion will be provided, including science missions to the moon and asteroids.

INSTRUCTOR:
Dr. James D. Thorne (Jim) is a leading expert on astrodynamics at a national security research center. He is a career veteran of the US Air Force during which time he focused on space technology, acquisition and policy. He has conducted analyses of space-related program concepts and also does independent research in the field of orbital mechanics. Jim published a time-explicit power series solution to a classical orbit determination problem, known in the literature as "Thorne's solution of the Lambert problem" and has also published basic research in continuous-thrust trajectory optimization. He holds a BS from Purdue University and MS & PhD degrees from the AF Institute of Technology, all in Astronautical Engineering. Jim is a member of the American Astronautical Society and is a frequent reviewer of technical journal articles in the field of astrodynamics.

Liquid Rocket Engine Design
DURATION: THREE DAYS
LOCATION: YOUR FACILITY
COURSE NO.: 5095
COURSE SUMMARY
This course explores the liquid rocket engine design problem from a system level. The requirements, issues, problems, and criteria that define and shape a new engine system design are covered in detail. The compromises involved in system level design, such as component interactions, are also covered at length. Several existing liquid rocket engine systems are used as case studies to illustrate the various principles involved. This course (or equivalent knowledge and experience) is a prerequisite to the three-day Course Number 5098, Advanced Liquid Rocket Engine Design Workshop, which is most often conducted on a client-site basis.
COURSE MATERIALS:
Each attendee will receive a printed copy of the class notes and an individual Certificate of Completion.
WHO SHOULD ATTEND:
Launch vehicle propulsion system engineers, project engineers, program managers, and other technical professionals who require or desire a well-grounded knowledge of how basic requirements evolve into rocket engine systems design, and how system level requirements influence component designs.
WHAT YOU WILL LEARN:
Classification of various types of liquid rocket engine systems. An overview of types of components employed in the above systems. The reasons for design trade-offs and choices.
