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

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

Major Area for Facility Upgrades Vibration Test Area

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

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

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

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) Typical 60,000 ft3 Reverberant Acoustic Test Facility

Thermal Vacuum Testing Cryogenic Systems Reconfigure existing shroud panels to 40 foot tall x 40 wide x 80 ft long envelope Cryopanel end walls will swing open to allow test article insertion Assembly platform with attached cryofloor will be used for build-up of test article in Assembly Area and allow integrated unit to be moved to test chamber on rail system ISS Testing Cryoshroud Configuration Solar Simulation Build test specific lamp structure Full surround lamp structure with movable sections to allow deployments Existing Power Supply/Controllers 14 zones (7.2 MW) Maximum 400 kW/zone.
