1. Space Power Facility (SPF) CEV Environmental Qualification Testing DISCLAIMER: This Initial Government Concept does not represent a preferred Government approach or solution.

3. Space Power Facility Cutaway View

4. Facility Architecture for CEV Testing
Random and Acoustic Vibration Test Area
Thermal/Vacuum and EMI/EMC Test Area
Assembly and Integration Area

5. Operations Flow
* SPF Specific Schemes/Techniques Provide Low Risk Handling of Hardware

6. Major Area for Facility Upgrades Vibration Test Area

7. EMI/EMC Testing
All tests are performed inside the aluminum vacuum chamber using the chamber as an RF shield
Minimum facility modifications required
Facility survey was performed showing very low RF noise
Utilizes large chamber size to position EMI equipment using movable platforms

8. EMI/EMC Testing
Aluminum vacuum chamber is well suited for radiated susceptibility testing, and for radiated emissions testing
Data traces shown in figure indicate that the RF energy penetrating into the chamber is below thresholds used in the International Space Station Program

9. Random Vibration Testing
Large 3 axis state-of-the-art shaker system sized to test CEV full stack and LSAM (LSAM mass 120,000 lbs)
7 shaker system allows for ease of changeover to vertical axis testing
4 – 45,000 lb horizontal
3 – 65,000 lb vertical
New data acquisition and control system
450 channel data acquisition system will be used for both random and acoustic vibration testing
1.4 million lb seismic mass installed in high bay
Shaker slip table below grade allows for full stack testing
Facility can be modified to handle tanks filled with isopropyl alcohol

10. Acoustic Vibration Testing Chamber Characteristics
Build a new 80,000 ft3 (40ft x 45ft x 46 ft tall) RATF with capability of 163 dB in the empty chamber
The design of this chamber utilizes known state-of-the-art technology for acoustic testing at these levels and is considered the most powerful chamber that can be built of this size
Chamber size is large enough to test the integrated SA/SM/CM/LAS boost cover and the LAS tower as a separate test
Chamber size and chamber access doors are large enough to allow testing of the LSAM
GRC Utilized Wyle Laboratories for proposal information (worlds leading expert in building acoustic facilities)
