Approved for public release; distribution is unlimited / A low speed wind tunnel investigation was conducted to
examine the aerodynamic characteristics of the flowfield
around a three percent scale YF-17 lightweight fighter
prototype model at high angles of attack using flow
visualization and force and moment measurements. Smoke
filaments, injected into the wind tunnel test section, were
illuminated by a laser sheet to highlight flow phenomena
about the model. Force and moment measurements were made
using a precision six-component strain gage balance. The
investigation marked the first attempt at qualitative flow
analysis using the laser sheet flow visualization system
recently installed in the Naval Postgraduate School low speed
wind tunnel facility. The investigation was undertaken to
specifically identify flow phenomena and/or regions of
interest that may have bearing on the design and performance
of supermaneuverable aircraft. The data indicate a good
correlation between the observed flow phenomena and force and
moment measurements at various angles of attack, thus
establishing the credibility of such experimental
investigations for high angle of attack aerodynamic research. / http://archive.org/details/experimentalinve00leed / Lieutenant Commander, United States Navy
