  • Fiber optic tufts for flow separation detection
    Patent number: 6636320
    Abstract: Flow separation detectors and, more particularly feedback sensor arrangements consisting of optical fiber tufts adapted to provide for the measurement of surface aerodynamic flow phenomena through the effects birefringence or transmitted light, and especially with regard to aerodynamic flow separation which is encountered over a surface. Also facilitated is the detection of aerodynamic flow separation with a concurrent detection of encountered mechanical strain and stresses on the surface structure being monitored.
