31 Αυγ 2021 · Menezes et al. compared the effects of different aerospikes in reducing drag and aerodynamic heating. The geometric model for their experiment is shown in Figure 1(a) and is widely used to verify the accuracy of numerical methods.
1 Ιαν 2013 · Drag reduction for aerial vehicles has a range of positive ramifications: reduced fuel consumption, larger operational range, greater endurance and higher achievable speeds.
23 Ιουλ 2018 · Energy deposition techniques by using laser and plasma can reduce aerodynamic heating and wave drag of hypersonic flows. Magneto aerodynamic technique can reduce drag and aerodynamic heating, by the addition of the magneto technology in hypersonic flows.
Aerodynamic drag reduction plays an important part in achieving fuel consumption targets. Cooling intake areas are smaller and flow through the radiator is often extremely inhomogeneous, which can substantially reduce cooling performance, as shown by Chiou [1].
12 Μαρ 2022 · Efforts in the form of sleek aerodynamic designs, better propulsion systems, and the implementation of passive and active techniques are generally adopted to achieve a weaker shock wave system. Shock reduction can improve flight range, reduce fuel consumption, and provide thermal protection of the forebody region.
1 Ιουν 2020 · A novel combinational configuration is proposed to reduce the hypersonic aerodynamic drag (Fig. 1). The basic configurations are the spike, nose cone, front and rear jets, respectively. The nose cone is a hemisphere, and its diameter D is 100 mm.
22 Οκτ 2019 · From examination of the instantaneous flow fields, a drag reduction mechanism by riblets is proposed: riblets with small spacings reduce viscous drag by restricting the location of the streamwise ...
