PROTEIN CRYSTAL GROWTH (PCG) DIFFUSION CONTROLLED CRYSTALLIZATION APPARATUS FOR MICROGRAVITY (DCAM) VERIFICATION REQUIREMENTS
|Publication Date:||31 October 2001|
This document establishes the verification requirements for the Diffusion controlled Crystallization Apparatus for Microgravity (DCAM) flight hardware and its Ground Support Equipment (GSE). These requirements are the basis for a verification program that will demonstrate that the DCAM satisfies safety, interface, and performance requirements. These verification requirements will ensure the DCAM capacity to perform ground processing at the Kennedy Space Center (KSC) and/or Dryden and mission objectives while located in the Shuttle Middeck, Spacehab, and/or ISS. If the DCAMS are flown inside an STES, then the STES-DCAM assembly will be mounted in an Expedite the Processing of Experiments to Space Station (EXPRESS) Rack in the US Lab of the ISS. Ascent / descent location of the STES-DCAM assembly will be in the Shuttle Middeck or Spacehab. Ascent / descent location of the stowage (ambient) DCAM assembly will be determined by the availability of stowage space.
Compliance with safety, interface, and performance verification requirements will ensure that the DCAM can be installed in either a Single locker Thermal Enclosure System (STES) or a standard middeck locker as stowage. Verification activities include demonstration, testing, inspection, and analysis. The majority of these requirements will be verified at the Marshall Space Flight Center (MSFC); however, because the DCAM is a late-load experiment (Launch minus 24 hours), some verification requirements must be completed at the Kennedy Space Center (KSC).
The DCAM will be verified to the specific safety and interface design requirements contained in NSTS 1700.7 & ISS Addendum, KHB 1700.7, NSTS-21000-IDD-MDK, MDC91W5023K, and SSP 57000. The DCAM will have its performance verification requirements certified via the DCAM CEI Spec, MSFC-SPEC-2498. In order to satisfy these requirements, this document addresses the following disciplines: environmental, mechanical, structural, thermal, materials, human factors, performance, safety, and Ground Support Equipment (GSE).
Each Verification Requirement Definition Sheet (VRDS) is set up to accommodate requirements originating from the Shuttle Middeck, the ISS, or the Spacehab. In conjunction with each one of these requirements is a block devoted to the CEI Spec requirements. Verification compliance data shall be submitted based on the current manifest. In other words, if the hardware is planned for ascent in the Shuttle Middeck, flight operations on the ISS, and descent in the Shuttle Middeck, then verification compliance data shall be submitted to satisfy both cases, where required. Should there be conflict between a CEI Spec requirement and another requirement block, the more stringent of the two requirements shall be met.
This verification requirements document was prepared and submitted by the Program Development branch, Teledyne Brown Engineering, Contract # NAS8-00205, in accordance with Marshall Work Instruction (MWI) 8050.1, Revision B, Effective Date March 6, 2000.
