DITECT Camera Used to Measure Dynamics of Bumblebee Flight
A recent publication relied on DITECT’s motion analysis software “DIPP-MotionV” and high-speed camera “HAS-D73.”
The paper is titled, “Design of a gust-generating wind tunnel for dynamic identification of micro air vehicles and bumblebee flight.”
The Abstract for this paper:
A gust wind tunnel designed to generate predictable wind patterns for aerodynamic testing was developed. From the detailed wind speed measurements in the test section, a wind gust model was constructed to characterize the time and positional variation of the wind speed and direction. The wind gust model, verified using hot-wire velocimetry, exhibited an error of less than 1%. The constructed wind gust model enabled the identification of the flight dynamics of objects in free flight, such as flapping insects. The dynamic model of a bumblebee flying in gusty winds was analyzed in a wind tunnel, and the transfer functions for the pitch angle and z-directional velocity in response to gust inputs were identified. Singular value analysis of the identified dynamics revealed that the control gain was adjusted either to decrease gust responses or improve robust stability according to wind conditions.
