Test Stand Design
Test Stand Development
4000 HP tail rotor gearbox test stand
Hydraulic test facility
1000 HP prototype engine 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, we provide
detailed designs. In addition to mechanical designs, we
incorporate 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
