“…The airflow domain, as shown in Figure 4, was built around both Neo-Ptero models according to the total chordwise aircraft length (C = 594.5 mm) as proposed by [9,10]. Only half of the airflow domain and the Neo-Ptero models were implemented in the virtual wind tunnel analysis to avoid computational burden [11].…”

This paper presents the investigation and improvement of lift and drag characteristics of Neo-Ptero micro-UAV models based on the virtual wind tunnel method. Despite its successful development and flight stability, the lift and drag coefficients characteristics of the current Mark 1 Neo-Ptero remain unknown. To improve the Mark 1 Neo-Ptero performances, Mark 2 Neo-Ptero model has given a new unsymmetrical airfoil wing configuration. The computational aerodynamic analysis was executed and focused on certain lift and drag coefficient characteristics. Lift coefficient results showed that Mark 2 improved in overall lift characteristics such as zero-lift angle, maximum lift magnitude and stall angle magnitude. Conversely, Mark 2 model suffered a slightly higher drag coefficient magnitude and more significant drag increment percentage than Mark 1. However, the trade-off between superior lift magnitude and minor drag generation induced by Mark 2 boosts the model’s aerodynamic efficiency performances but is only limited at early angle stages.

“…Research shows that fuel consumption will be reduced by 7percent to 9percent if the aerodynamic drag coefficient is reduced by 20percent for a medium duty van when traveling at 80Km/h [1]. Therefore, reducing the aerodynamic drag of vehicle when driving plays a significant role in energy saving, emission reducing and environment protecting [2][3][4].…”

Aerodynamic drag reduction of commercial truck at high speed is one of the important ways to reduce its energy consumption. CFD simulation and wind tunnel tests are performed on a kind of commercial truck, to study the influence of the cab shape and different kinds of guide cowls on aerodynamic drag, and the impact mechanism was also analyzed. It shows that the cab shape will make great contributions to the aerodynamic drag while the truck travelling, and through improving the shape of cab, guiding the air flow passed, it can effectively reduce the aerodynamic drag and achieve energy saving.
