- Shape Measurement of Deployable Flexible Aeroshell during Ventilation in Low-Speed Wind Tunnel using ToF Camera
抄録
<p>Deployable flexible aeroshells have the potential to innovate atmospheric entry systems and space transportation technology. This study constructed and validated a shape measurement system for deployable flexible aeroshells during low-speed wind tunnel ventilation. The system consists of two Time of Flight (ToF) cameras with a wide measurement range and a high sampling rate. By software control, these can simultaneously capture and store depth images at 30 fps. A post-analysis method for ToF camera data with moving objects is proposed, and the obtained front projected area of the flexible aeroshell was verified. The proposed method could provide reasonable results and adapt to the object's position changes without readjusting parameters. The front projected area of the flexible aeroshell estimated from the ToF measurement data was consistent with trends that can be visually observed and with the results of structural strength tests. A positive correlation between aerodynamic forces and the front projected area was also confirmed. </p>
