Eidetics Awarded NASA Dryden SBIR Phase I Contract for Enhanced
NLF Air Foil Pressure Recovery with Boundary Layer Mixing Devices
14, 1998 - Eidetics Corporation was recently awarded a Phase I Small Business Innovation
Research contract sponsored by NASA Dryden. The Phase I program, entitled Enhanced
NLF Airfoil Pressure Recovery with Boundary Layer Mixing Devices was one of
345 proposals selected from a total of 2,335 proposals submitted.
"The Phase I research has shown that Boundary Layer Mixing Devices are
capable of preventing separation in an adverse pressure environment, with
laminar flow conditions upstream. This capability makes BLMDs well suited to
enhancing the pressure recovery of an extremely aggressive NLF airfoil design. A
relationship between device drag and the ability of BLMDs to overcome larger
adverse pressure gradients has been observed. A variety of BLMDs were tested
during the Phase I research, and the effects of size, shape, spacing and
location were quantified.
Phase II research will concentrate on the design of a
new family of NLF airfoils that take advantage of BLMDs. The knowledge gained in
the Phase I research will be used to create a design toolkit that integrates
with existing inverse airfoil design software. The result will be a new software
design tool and an airfoil design service capability."
