Sinha Deturbulators: Flight Test Evaluation

Jim,
Is it a passive system, no current?

it six times with those shiny silver strips on the wings, then three
times without. What did they learn? Come to the Convention in Memphis
to find out. Dick, as usual, will tell it straight. Will you laugh?
Will you be dumbfounded? Will you believe?

Mike,

Yes, it is passive. Dr. Sinha started his research with active
surfaces. He used them both as sensors to frequency content in the
flow and drivers to control the flow. He eventually learned that you
can dispense with the complications of electrical control simply by
using the energy present in the flow-surface interaction. Think of
filtering attached turbulence flows into frequencies that are hard to
maintain down stream.
