	Example of a schematic of a proposed test cell

All aspects of the test cell are designed by Southwest Research Institute (SwRI), and a complete drawing package and all documentation necessary to fabricate a test stand and/or test facility are provided.

• 3D CAD models are generated that allow for tradeoff studies to be conducted and space allocation to be evaluated in advance of fabrication. These studies further help eliminate installation problems.

• Where mechanical fixturing is required, SwRI provides detailed designs. In addition to mechanical designs, SwRI incorporates the following functions:

  • Mechanical

  • Pneumatic

  • Hydraulic

  • Electrical

• Electronic systems involving instrumentation and data acquisition hardware are designed, and drawings showing point-to-point locations, grounding, and shielding are developed.

• A typical drawing package consists of:

  •  50 to 75 mechanical, electrical, and electronic drawings

  • Outline and installation drawing

  • Parts lists

  • Assembly drawings

  • Subassembly drawings

  • Detailed component fabrication drawings

  • Mechanical component drawings

  • Duct work drawings

  • Wiring diagrams

  • Facility modifications

  • Assembly/disassembly and maintenance procedures

• Fixture design includes:

  • Finite element analysis

  • Structural strength evaluation

  • Temperature considerations

  • Tolerance studies

  • Material requirements

  • Welding

  • Surface finishes

  • Fabrication instructions

• Data acquisition channel and system requirements are defined with a simultaneous selection of complimenting instrumentation and data acquisition hardware.

• Stringent software specifications are developed that encompass all aspects of the test cell including:

  • Data recording

  • Data analysis,

  • Data display

  • Calibration

  • Test stand control

  • Historical buffer

  • Emergency shutdown

  • Graphical user interface
