Electrical re-gen?

Jason, how much of 6X energy improvement was related to the fact that the original test stands were 20-50 years old, and how much was it about using electrical re-gen?

Most of energy savings comes from recovering the power by applying load using AC motors.  The original test stands used conventional loading techniques, which equates to zero power recovery. Even though the original test stands were 20-50 years in age, this inefficient approach is still being integrated in new test stands to save cost upfront.  RedViking recognized the initial capital investment cost in the additional motors and drives, but saw the benefits in long term energy savings for our customer.

I agree with the concept given that this method eliminates two conversion points where energy would be lost as well as the fact that it increases the overall efficiency. This will not only further increase the overall savings but will also enhance the already enhanced effectiveness given that the energy savings are about six times the energy efficiency formerly required to run the helicopter test stands

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
