3.3. Influence of Initial Airspeed on Maximum Energy HarvestingThis section explored the influence of initial velocity change on the maximum energy gain of the UAV. The previous initial airspeed is 20 m/s, and the stall speed of the glider Fox is 7 m/s. Hence this paper selected the initial airspeed from 15 m/s to 25 m/s to compare the energy change. Figure 12 and Figure 13 show the results of the energy variation and maximum energy gain achieved.
