ATI's Spacecraft Power Systems course
|
|
Summary:
This two-day course covers the requirements-driven design principles of the spacecraft power subsystem and its major components. Power source section evaluates available and future technologies in power generation, with a focus on photovoltaic technologies. Energy storage section evaluates available and future storage technologies with a focus on battery technologies. Course cites multiple real-life examples to illustrate the relevancy of the presented material.
Instructor:
Jay Jenkins is a Senior Professional Staff member at the Johns Hopkins University Applied Physics Laboratory. He has over 15 years of experience in design and test of Aerospace Power Systems including roles as Battery Lead, Solar Array Lead, and Power Subsystem Lead. His career has afforded him opportunities for hands-on fabrication and test, concurrent with his design responsibilities. He has been recognized as a winner of the ASME International George Westinghouse Silver Medal for his development of the first solar arrays beyond Mars' orbit and the first solar arrays to orbit the planet Mercury. He is active in publication and has been recognized with two Best Paper Awards in the areas of Aerospace Power Systems.
Course Outline:
Day 1:
- Introduction to Space Power Systems Design. Power System overview with focus on the origin of design-driving requirements, technical disciplines, and sub-system interactions.
- Environmental Effects. Definition of the environmental considerations in the design of power systems including radiation, temperature, UV exposure, and insolation.
- Orbital Considerations. Basic orbit geometries and calculations for common orbits. Calculation of illumination profiles including effects of spacecraft geometries.
- Power Sources: Solar cell technologies and basic physics of operation including electrical characteristics and environmental susceptibility. Solar panel design, fabrication, and test considerations.
Day 2:
- Energy Storage: Battery technologies, and flight-readiness of each. Battery selection and sizing characteristics. Battery voltage profiles, charge/discharge characteristics, and charging methods. Special battery handling considerations. Alternative storage technologies include fuel cell technologies, and fly-wheels.
- Power System Architectures: System architecture and regulation options including direct energy transfer, peak-power tracking, and hybrid architectures. System level interactions and trade-offs.
- Design Example: Sample power system concept design of a LEO mission including selection and sizing of batteries, solar arrays. Focus on real-life trade-offs impacting cost, schedule, and other spacecraft activities and designs.
