This study develops an end-to-end load analysis scheme for flap and slat actuators, which comprise the aircraft’s high-lift system, and the analysis results are directly integrated into hardware optimization. Because they shoulder heavy responsibilities during the takeoff and landing phases, whether they can remain rock-solid under complex aerodynamic conditions or even remain unmoved in emergencies is directly related to their overall safety performance. This work process is closely linked and includes three major links. First of all, according to the CCAR-25.301 standard, the load envelope under normal working conditions is sorted out, and the limit cases of abnormal faults are exhausted. Subsequently, ANSYS Workbench pulled silk and peeled off the cocoons to capture the peak stress at the engagement between the output shaft and the gear. In the end, the closed-loop verification of the customized test bench made the theoretical calculations and the hardware-measured data exactly the same. The entire package provides designers with hardcore data support, and always uses airworthiness, not convenience, as the criterion when improving actuator performance.
Heavy-lift cargo aircraft operate under strict aerodynamic constraints due to high wing loading, large gross weight, and the need to balance low-speed lift with cruise efficiency. This study presents a comparative aerodynamic analysis of NASA Phase-2 supercritical airfoil–flap configurations for heavy-lift cargo aircra...

Owing to its superior aerodynamic efficiency and structural lightweighting potential, the blended-wing-body (BWB) layout has emerged as a promising configuration for next-generation unmanned aerial vehicles. However, the inherent aerodynamic deficiencies of the BWB configuration (e.g., poor low-speed takeoff and landin...

It is noted that in agriculture, fixed-wing unmanned aircraft systems successfully perform the tasks of crop monitoring, pest and disease detection across large areas remote from the operator. Further improvements in unmanned aircraft speed, flight range, and payload capacity can be achieved by reducing aerodynamic dra...
