My guess is that the original collection of test stands was created as each different type of helicopter was designed, probably by the first builders of each model. It often happens that way. And so there is a collection of test stands, each representing a different approach to different requirements and built over a span of many years. Designing a different stand to test all of the models with a different set of requirements is a great idea, but it is quite different from what the first projects were. And as system requirements change a lot, the original systems are not able to meet the new requirements. Not bad engineering, just "long ago and different specifications" engineering. Change will bury us if we aren't careful.
Thanks for the interest and question. RedViking has developed a test stand control and software platform called RedRaven that incorporates a supervisory host system, PLC based machine function and safety control, high performance drive control, and integrated high speed data acquisition. The manufacturers of the hardware can very but in this case we integrated Rockwell AB PLCs, NI data acquisition hardware, and Siemens drives and Motor. The host system, which includes the HMI software, is all custom LabVIEW code.
I would have thought that the old system would have, at the least , had test pallets where the device under test could have been loaded, off the test stand, and then put on the test stand and the test stand connections quickly made.
It sounds like the original stands were made to maximize cost at the expense of efficientcy.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
