Don Edberg's Spacecraft Design & Systems Engineering Class

The lecturer for this class is Donald Edberg, PhD, Professor of Aerospace Engineering, California State Polytechnic University, Pomona, CA.  Formerly a Boeing Technical Fellow at Boeing Information, Space, and Defense Systems, Huntington Beach, CA, Dr. Edberg has 20+ years of experience in the aerospace industry and has been employed at General Dynamics, the Jet Propulsion Laboratory, AeroVironment, McDonnell Douglas, and the Boeing Company in addition to his position at Cal Poly Pomona.  Dr. Edberg has also taught aircraft, spacecraft, and structural design courses at UCLA, UC San Diego, and UC Irvine, and has consulted for a number of small companies.  He teaches full-time at Cal Poly Pomona, and was a Technical Fellow at Boeing’s Phantom Works until June 2009.

During his career, Dr. Edberg has worked on launch vehicle and on-orbit space environments, aerodynamic testing of launch vehicles at high angles of attack, experimental modal and dynamic analysis, smart structures and materials, launch vehicle load mitigation, reduction of on-orbit mechanical vibrations, and microgravity isolation systems as well as the development of an electric-powered, back-packable UAV now in service as the FQM-151 Pointer.  Dr. Edberg holds ten U.S. patents in aerospace and related fields and was the inventor of and chief engineer for the patented McDonnell Douglas STABLE (Suppression of Transient Acceleration by Levitation Evaluation) vibration isolation system.  STABLE was successfully demonstrated during flight on space shuttle flight STS-73 carrying USML-2 during Oct. 1995.  Dr. Edberg is an Associate Fellow of the American Institute of Aeronautics and Astronautics and an active UAV pilot.

Don has put together a comprehensive class on Spacecraft Design and Systems Engineering.  The class is offered by UCLA Extension and Taksha University, and can be taken on the UCLA campus or can be presented on-site (over 250 have attended this class, which has been given on 19 separate occasions since 2005 at UCLA, Boeing Satellite Systems, El Segundo, CA, Northrop-Grumman Space Technology, Redondo Beach, CA, Norfolk, VA, and at NASA Langley Research Center, Hampton, Virginia).

This course presents an overview of all the factors that affect the design and operation of satellites and spacecraft. It begins with an historical review of unmanned and manned spacecraft, including current designs and future concepts. All the design drivers, including launch, on-orbit environment, and atmospheric entry are covered, including launch vehicle engineering and its effect on the spacecraft design. Orbital mechanics is presented in a manner that provides an easy understanding of underlying principles as well as applications, such as maneuvering, transfers, rendezvous, and interplanetary transfers. Considerable time is spent defining the systems engineering aspects of spacecraft design, including the spacecraft bus components and the relationship to ground control. Design considerations, such as structures and mechanisms, attitude sensing and control, thermal effects and life support, propulsion systems, power generation, telecommunications, and command and data handling are detailed. Practical aspects, such as fabrication, cost estimation, and testing, also are discussed. The course concludes with several examples of and the lessons learned from spacecraft failures.

This course is ideal for an engineer with a particular specialty, as well as a scientist or instrument specialist, who needs to obtain a solid background in the "big picture" of spacecraft design and how the pieces of the puzzle have to fit together. Managers who want to understand the many aspects of spacecraft design that affect their work, tasks, and scheduling should also benefit from this course. Note that the course may be presented over three contiguous days (see schedule below) or can be presented over six weeknights, each three hours long (Los Angeles area only).

Testimonials:

"This course expanded my general knowledge and broadened my basic understanding of spacecraft design. It covered and explained areas of design that I had very limited understanding of." S.R., Engineer Specialist, Northrop-Grumman Corp.

“I again wanted to say that I really enjoyed your class and recommended to my management that all of our new hires should take such a class.  It is certainly very useful to see your own area in the context of the entire space picture.” C.S., Senior Engineering Specialist, Aerospace Corp.

"This is an excellent course!! Dr. Edberg is an excellent communicator and has the ability to explain complex terms in an intelligible manner." S.Y., Principal Investigator, NASA Langley

"Excellent course for people like me who wish to go into program management." M.R., Engineer, Boeing Houston

"This course was great. Instructor was able to simplify but not talk down to audience. He explained all terms likely not to be understood." Anonymous.

"Thanks! This was a great course. I especially liked the launch vehicle section and some of the communication and CDHS stuff." Anonymous.

"The course was both enjoyable and very thorough. Having the slides available for additional notes was very helpful. Great course!" Anonymous.

"Would recommend. As a non-technical person some content was beyond my job scope, but explained well and gives me a reference for later." N.P., Contract Administrator, Boeing

"Great lectures. Interesting. Not boring at all. Great notes, references for further investigation and research." V.B., Engineer, Boeing
