Eidetics Awarded Air Force Research Laboratory Small Business
Innovation Research Phase II Contract for Active Reduction of Skin Friction
August 31, 1998 - Eidetics Corporation was recently awarded a Phase II Small
Business Innovation Research contract sponsored by the Air Force Research Labs.
The Phase II program, entitled Active Reduction of Skin Friction Drag is
a continuation of the Phase I program completed by Eidetics.
"Aircraft range is limited by aerodynamic drag and even a
modest reduction of the drag provides significant fuel savings. Recent advances
in electronics and control technologies make active boundary layer control
practical. The integration of modern control systems with aerodynamic boundary
layer control allows a major reduction in skin friction drag. The overall
objective is to provide a reduction in turbulent boundary layer drag without
offsetting aerodynamic penalties or excessive power requirements.
active flow control devices demonstrated in Phase I will be integrated with flow
sensors and a control system to create a practical turbulent drag reduction
system. The system performance will be demonstrated during wind tunnel tests
with fuselage and wing models. In comparison with passive techniques, the active
device offers the benefits of smaller size, less device drag, greater
effectiveness and flexible control over a wide range of operating
