Stereo-Video Data Reduction of Wake Vortices and Trailing Aircrafts
نویسنده
چکیده
This report presents stereo image theory and the corresponding image processing software developed to analyze stereo imaging data acquired for the wake-vortex hazard ight experiment conducted at NASA Langley Research Center. In this experiment, a leading Lockheed C-130 was equipped with wing-tip smokers to visualize its wing vortices, while a trailing Boeing 737 ew into the wake vortices of the leading airplane. A Rockwell OV-10A airplane, tted with video cameras under its wings, ew at 400 to 1000 feet above and parallel to the wakes, and photographed the wake interception process for the purpose of determining the three-dimensional location of the trailing aircraft relative to the wake. The report establishes the image-processing tools developed to analyze the video ight-test data, identi es sources of potential inaccuracies, and assesses the quality of the resultant set of stereo data reduction.

متن کاملKinematics and Dynamics of Sphere Wake Transition
The wake of a sphere undergoes a number of symmetry-breaking transitions as it changes from laminar to turbulent. This paper concentrates on the "rst two transitions. At Re"212 a regular transition occurs, when the wake develops a spectacular two-tailed structure consisting of two trailing streamwise vortices. During the second transition at Re"272 the #ow undergoes a Hopf bifurcation. In this ...
متن کاملTime-resolved vortex wake of a common swift flying over a range of flight speeds.
The wake of a freely flying common swift (Apus apus L.) is examined in a wind tunnel at three different flight speeds, 5.7, 7.7 and 9.9 m s(-1). The wake of the bird is visualized using high-speed stereo digital particle image velocimetry (DPIV). Wake images are recorded in the transverse plane, perpendicular to the airflow. The wake of a swift has been studied previously using DPIV and recordi...
متن کاملAerodynamics of gliding flight in common swifts.
Gliding flight performance and wake topology of a common swift (Apus apus L.) were examined in a wind tunnel at speeds between 7 and 11 m s(-1). The tunnel was tilted to simulate descending flight at different sink speeds. The swift varied its wingspan, wing area and tail span over the speed range. Wingspan decreased linearly with speed, whereas tail span decreased in a nonlinear manner. For ea...
