Vertical temperature profiles obtained from Venus Express and Akatsuki radio occultation data using FSI
<p>Vertical temperature profiles of Venusian atmosphere obtained from selected radio occultation data taken in ESA's Venus Express and JAXA's Akatsuki missions. The temperatures were retrieved using a radio holographic method, Full Spectrum Inversion (FSI). The data list and format are given in two Excel files and the data are given in text files with an extension ".dat".</p>

The present paper focuses on a parametric<br>study of the aerodynamic performance of a bionic flexible clapping wing. The proposed<br>model deforms the wing in spanwise and chordwise directions based on the six rigid<br>bodies connected along the wing veins using ball links and springs. Unsteady effects of<br>flapping wing micro air vehicles with a double clap-fling configuration are investigated<br>using an air-solid interaction model based on smoothed particle hydrodynamics and<br>rigid multi-body dynamics. A validation experiment determined the convergence<br>conditions and computational model accuracy. The proposed numerical model is<br>evaluated in terms of flexible variation law and aerodynamic performance. The results<br>indicate that the flapping frequency, angle of attack, and wind velocity significantly<br>influence the lift. Furthermore, increasing the frequency will monotonically expand<br>the maximum and time-averaged lift curve values. When the angle of attack is less<br>than 30 ◦, the influence on the time-averaged and maximum lift is proportional to the<br>angle of attack. When the angle of attack is larger than 45 ◦, a stall-like condition<br>is detected. To broaden the applicability of the present findings, a dimensionless<br>parameter, reduced frequency, is defined, and its influence on the maximum and time-<br>averaged lift is investigated. This parametric study shows that as the reduced frequency<br>increases, the maximum and time-averaged lift increases and then decreases. The<br>present study could reach a modeling framework that better explains the clapping<br>wing aerodynamics.<br> </p>
