Environmental forces, whether natural or induced, produce mechanical and thermal loadings on spacecraft. Early in the development of any spacecraft, these loads must be estimated and incorporated into the design, analysis and test programs. Environmental specifications are the basis for test levels which are used to verify the design and workmanship of a space vehicle. The Spacecraft Environments Course provides participants with the necessary background and tools to produce a set of environmental specifications and test levels for any satellite development program. Emphasis is placed on how to progress from the measurement or analytical estimation of launch and on-orbit environments to a specification that can be incorporated into a space vehicle test verification program.
Each attendee will receive a complete set of course notes and materials.
WHO SHOULD ATTEND:
The course is also ideal for managers and systems engineers wishing to gain an in-depth understanding of how spacecraft environments and resulting requirements creep can impact their program risk.
WHAT YOU WILL LEARN:
How to Estimate environmental loads on spacecraft.
How to plan a test program to fully qualify a flight spacecraft for a variety of environmental load scenarios.
Key spacecraft testing rules-of-thumb and sanity checks.
Environmental test criteria.
Acceptance test facility design considerations.
The use of test data to support analytical model validation.
