Area of Science:

  • Fluid dynamics
  • Aerodynamics
  • Experimental methods

Background:

  • Transonic airfoil aerodynamics are complex, requiring precise flowfield measurements.
  • Understanding flow separation and wake behavior is crucial for aircraft design.

Purpose of the Study:

  • To investigate the flowfield around a transonic airfoil using FLEET velocimetry.
  • To assess the capabilities of FLEET for aerodynamic research.

Main Methods:

  • Femtosecond laser electronic excitation tagging (FLEET) velocimetry was employed.
  • Two-component velocity measurements were taken in a transonic wind tunnel.
  • Data was collected at various angles of attack (0°, 3.5°, 7°).

Main Results:

  • FLEET accurately resolved mean and fluctuating velocities in the airfoil wake.
  • Flow separation was identified at higher angles of attack.
  • Measurement precision reached 1 m/s with a dynamic range of 500.

Conclusions:

  • FLEET velocimetry is a sensitive tool for aerodynamic flowfield analysis.
  • The technique effectively captures complex flow phenomena like shear layers and separation.
  • FLEET offers high precision and dynamic range for transonic flow studies.
