“…On the other hand, at the angles of attack accompanying the stall, a much larger angle can be noticed that is needed to lose the lift in relation to the LS model [27]. The PD model, on the other hand, excels here with a very high value (24.7 • -marked with the green circle in Figure 10).…”

The purpose of this article is to present and discuss the results of a non-standard unnamed aerial vehicle construction with a constant cross-section square-shaped avionic profile. Based on the model’s in-air observed maneuverability, the research of avionic construction behavior was carried out in a water tunnel. The results show the model’s specific lift capabilities in comparison to classical avionic constructions. The characteristic results of the lift coefficient showed that the unmanned aerial vehicle presents favorable features than classic avionic constructions. The model was created with the prospect of using it in the future for dual-use purposes, where unmanned aerial vehicles are currently experiencing very rapid development. When creating the prototype, the focus was on low production cost, as well as convenience in operation. The development of this type of breakthrough avionic solution, which shows extraordinary maneuverability, may contribute to increasing the popularity and, above all, the availability of unmanned aerial vehicles for the largest possible group of recipients because of high avionic properties in relation to the technical construction complexity.

“…To analyze the maneuver control in gliding/soaring flight (without wings flapping) initial conditions for aerodynamic simulation are required for characteristic angles of the lifting surfaces (eg: the dihedral angle of the wing, lateral and longitudinal angles of the tail assembly/tail). Validation of the results with free software tools should be compared with commercial CFD codes (i.e., Solidworks-Floworks, Ansys-Fluent) which provide a high degree of confidence on the pre-processing and post-processing data analysis, [29,30].…”

In the international research, biomimetic lifting surface are analyzed in various aspects: construction, aerodynamics and energy. The specificity of the flying wings determined similarity between the aeromechanical and the biomimetic concepts leading to numerous challenges in terms of construction, aerodynamics and actuation. The Aeromechanics of the biological flight focuses both on the various forms of lifting surfaces and the biomechanical aspects. This article contains a number of references to the biological inspiration of the morphing concept, a brief introduction to the theoretical area of the flying wings and a numerical analysis of biologically similar morphing geometry completed by conclusions and future approaches.

“…Mokhtar [6] conducted a parametric study of high-lift airfoils including the Eppler E423, Douglas/Liebeck LNV109A, NACA 9315 and Selig S1223, and proposed a new WM004 airfoil section. Prisacariu [7] used Easy CFD software to analyze the Phoenix, Clark YH, and MH91 airfoils for flying wings. Dinh et al [8] concluded that the TL54 airfoil provides superior aerodynamic performance based on a collection of low-speed FW UAV airfoil series (Eppler, MH, HS series etc.).…”

The aim of the study is to investigate how the choice of airfoil affects the aerodynamic characteristics of a flying wing UAV. For this purpose, comparative analyzes were performed for four different airfoils: MH60, TL54, Eppler 339, and TsAGI 12%. Given the maximum range performance (maximum lift /drag ratio), the best aerodynamic efficiency is given by the flying wing UAV with MH60 and TL54 airfoil. Based on their maximum lift-to-drag ratio, the flying wing UAVs made with MH60 and TL54 airfoils exhibited the best aerodynamic efficiency. Specifically, the maximum lift-to-drag ratio for the flying wing with the MH60 airfoil was 33.1, while that for the flying wing with the TL54 airfoil was 32.7. Considering the pitching moment coefficient, the flying wing made with the MH60 airfoil and TsAGI 12% exhibited a more stable characteristic than the TL54 and Eppler 339 airfoils. Based on the results of the study, it was found that the flying wing UAVs made with the TL54 and MH60 airfoils outperformed those made with the Eppler 339 and TsAGI 12% airfoils in terms of maximum range, minimum descent rate, and maximum endurance performance.
