The analysis of different feature geometries reveals varying efficiency trends across the designs. The fillet edge tail feature design demonstrates superior performance, particularly at higher flap angles, due to its ability to reduce drag and optimize airflow, ensuring stable efficiency. The full aerodynamic tail feature design performs well at lower flap angles but declines significantly as the flap angle increases, likely due to airflow separation. The partial aerodynamic tail feature design offers moderate and steady efficiency, balancing lift and drag. These findings highlight the aerodynamic advantages of the fillet edge tail for enhanced efficiency.

The analysis of different feature geometries attached to the wing reveals varying performances in terms of efficiency at higher AOA. The configuration with a full aerodynamic tail feature exhibits superior efficiency, attributed to enhanced airflow control and reduced drag. In contrast, the design with a partial aerodynamic tail shows lower efficiency, indicating some aerodynamic inefficiencies. The feature with a fillet edge tail performs slightly better than the partial design, demonstrating the benefits of reduced turbulence. Additionally, the straight triangular pointy tails, at both 45 degrees and 80 degrees, contribute to distinct efficiency levels, while the curved triangular tail shows potential for further optimization. Overall, the geometric design significantly influences performance, highlighting the importance of optimizing these features for enhanced efficiency.

The analysis of different tail geometries reveals varying efficiencies. The design with the full aerodynamic tail feature initially offers the highest efficiency but decreases as the flap angle increases, likely due to changing airflow dynamics. The design with the partial aerodynamic tail feature performs well at lower flap angles but also shows a decline with increasing flap angle, suggesting moderate aerodynamic benefits. The design with the fillet edge tail feature starts with competitive efficiency but declines more sharply, possibly due to increased drag. Overall, the full aerodynamic tail design demonstrates the best initial performance, highlighting the importance of optimal tail design for enhanced aircraft efficiency.

The fillet edge tail design of the feature attached to the wing demonstrates considerable variability in performance, reflecting a pronounced sensitivity to variations in flight parameters. This variability suggests that the aerodynamic effectiveness of this tail design is highly contingent on specific operational conditions, leading to inconsistent performance outcomes. Such sensitivity indicates potential challenges in achieving reliable and stable efficiency across diverse flight regimes. Future research should prioritize the optimization of this fillet edge tail design to address these performance fluctuations and enhance its aerodynamic stability and effectiveness under a wider range of flight conditions.

The stability analysis of subsonic aircraft with varying tailed feature configurations at higher angles of attack reveals that the full aerodynamic tailed feature maintains consistent performance across both alpha and beta angles, indicating its reliable aerodynamic behavior. The partial aerodynamic tailed feature shows optimal efficiency up to an alpha of 1 and performs best at lower beta angles, suggesting that smaller flap deflections favor its design. In contrast, the fillet edge tailed feature displays an efficiency peak at alpha=2, beyond which its performance declines, and demonstrates better stability at higher beta angles. These results suggest that the full aerodynamic tailed feature's consistent surface area provides stable airflow management, the partial aerodynamic tailed feature's design minimizes drag at lower flap deflections, and the fillet edge tailed feature's geometry might induce beneficial vortices at specific angles, enhancing lift temporarily before increased drag reduces efficiency.

The analysis of stability variations among prototypes with distinct tailed features reveals crucial insights into subsonic aircraft aerodynamics. Configurations featuring a full aerodynamic tailed feature exhibit superior stability at lower Alpha values, benefiting from streamlined airflow management and reduced drag. In contrast, prototypes equipped with triangular pointy tailed features, whether straight at 45 degrees or curved at 80 degrees, demonstrate enhanced stability at higher Beta values by minimizing vortex shedding and optimizing control effectiveness. Tailored design considerations based on these aerodynamic characteristics are essential for optimizing aircraft stability across varying flight conditions, highlighting the importance of tail geometry in aerodynamic performance and design optimization.

The analysis unveils varying efficiency levels among different tail geometries for feature prototype tails at different angles of attack (AOA). Notably, while the 45-degree triangular (straight) pointy tail consistently exhibits high efficiency, the unexpected decrease in efficiency observed with the fillet edge tail configuration may stem from its potential to disrupt airflow patterns and induce drag. Conversely, the prototype with an 80-degree triangular (curved) pointy tail showcases a remarkable increase in efficiency, likely due to its ability to minimize separation and reduce drag through optimized airflow control. These findings underscore the intricate interplay between tail geometry and efficiency in feature prototype design, offering valuable insights for future optimization aimed at enhancing aerodynamic performance.

The current findings illuminate the intricate relationship between feature geometry and aircraft efficiency, particularly at higher angles of attack (AoA). The observed dramatic fluctuations in efficiency in a prototype featuring a fillet edge tail suggest a heightened sensitivity to variations in AoA, highlighting the importance of tail design in influencing performance. Furthermore, the competitive efficiency levels demonstrated by prototypes equipped with aerodynamic tails showcase the effectiveness of this design approach. However, the stability exhibited by one specific prototype with a full aerodynamic tail underscores the robustness of this configuration in maintaining efficiency across diverse conditions. These insights emphasize the critical role of feature geometry in shaping aircraft efficiency and warrant further investigation for optimization and improvement in future research endeavors.
