Infrared Thermography and DIT of Quadcopter Rotor Blades Using Laser Heating

A measuring method to detect wall flow topologies by active infrared thermography coleman 125 ut parts was developed.Quadcopter rotor blades were studied in typical hover and forward flight conditions, while using a high-power infrared laser to heat the blade surface.By this, the distance between heat source and measuring object could be significantly increased compared diablo 2 amn rune to conventional heat sources.The resulting images show little blurring at high signal-to-noise ratios.

In steady-state flow conditions, wall flow topologies could be detected reliably and show good agreement with performed oil-film interferometry measurements.Wind tunnel experiments at forward flight conditions were conducted and indicate unsteady shifts of the transition location.
