The stabilator was mounted on a 10-chord boundary 45 45 subsonic wind tunnel. The stabilator was mounted on a 10-chord boundary layer layer splitter plate. Because the stabilator was balanced around the aerodynamic centers, splitter plate. Because the stabilator was balanced about the line of line of aerodynamic centers, there was no adjust in quasi-static deflectionwith rising airspeed. there was no modify in quasi-static deflection levels levels with escalating airspeed. The dynamic testing did show some rather profound variations because the closed-loop dynamic test frequencies became so high that the reduced frequencies exceeded a worth of 1 at low speeds. Accordingly, shed spanwise vortex damping clearly impacted resonance peak maxima. Testing was performed at 72 F (22 ) 29.97 inches (761 mm) mercury.Actuators 2021, ten,13 ofThe dynamic testing did show some rather profound variations as the closed-loop dynamic test frequencies became so higher that the lowered frequencies exceeded a value of 1 at low speeds. Accordingly, shed spanwise vortex damping clearly impacted resonance peak maxima. Testing was carried out at 72 F (22 C) 29.97 inches (761 mm) mercury. Figure 16 displays the effects of high reduced frequency damping on dynamic deflections. Clearly, aerodamping effects are elevated with rising frequency. While the resonance peak was clearly lowered at resonance, the dynamic corner frequency was nonetheless in excess of 140 Hz. Given the aeromechanics explained within the introduction of this paper, a corner frequency in excess of 140 Hz is far more than enough to appropriately capture and control even the quickest aeromechanical modes for the higher speed subscale aircraft below consideration. Though driving the stabilator at higher deflection levels was absolutely Actuators 2021, 10, x FOR PEER Evaluation 13 of 15 doable, as the deflections would breach 1 , the shell would attain the bump stops, which would avoid rotation levels beyond the rotational limit.Figure 16.
