Aerodynamic performances of all sample shapes chosen via DOE were evaluated by N-S equations CFD calculation, and the grid of each shape was generated automatically through Gridgen-based script. Then, the multi-object genetic algorithm NSGA-1I was employed to find the optimized design based on ...
Insects impress by their agility and their performances in flight. Understanding the aerodynamic mechanisms involved constitutes a considerable challenge for biologists and physicists, but also for engineers responsible for the design of robotics such as micro air vehicles, whose principal model is the ...
Skin corrugation and tandem configuration are two distinct features that characterize the flow around dragonfly wings. In contrast to the smooth airfoil and single pair of wings of conventional airplanes, corrugated surfaces and tandem wings influence ae
The measured and predicted overall performances of the 5-stage compressor at design speed are presented in Figure 4. Compared with the test data, it is clear that the shape of the speed line predicted by the multi-stage CFD is similar to the experimental line, where the error bars were ...

The blended-wing-body (BWB) aircraft equipped with distributed propulsion (DP) has gained continued attention due to its obvious potential in improving the performances of aerodynamics, propulsion, flight control, noise, and emissions [1,2,3,4]. This configuration is widely used in the concept ...
CRM-NLF configuration—global aerodynamic performances (M = 0.8565, Re = 15 × 106). Lines—aerodynamic module; symbols—experiments. (a) CL(α). (b) CL(CD). 4.1.4. NLF Regional Aircraft Configuration The CRM-NLF configuration considered laminar flow on the upper wing only. In order to...
The ∆z = 0.875b and ∆z = 1b positions with the best performances are the 13th and 23rd analyses, respectively. In both analyses, ∆y = 0 m and the performance improvements are 11.43% and 11.56%, respectively. The histogram also shows us that there are performance degradations as ...
