Hollow three-dimensional model for fuel reduction in aviation industry

In the past two years, the pandemic situation has affected the aviation industry drastically. This situation starts to change,
gradually, which is about to highly increase the international air travel around the world. Commercial air transport emission
contributes a significant amount to global warming. Hence, in this research, to reduce the fuel consumption in commercial
aircraft the aerodynamic surface of the wing is improved with the help of a hollow model in three dimensions. This biomimetic
model named Raw Riblet was derived from a shark’s skin texture. The cross-section of the wing was (NACA 0012) designed
and the Raw Riblet model was implemented in two different ways, computationally, and formulated biomimetic aerofoil
models such as BRR and LRR (0.455). All these aerofoil models were analysed in high-speed airflow, computationally, and
the aerodynamic performance values were noted. All the computational results were validated, and the result analysis showed
a promising decrease in viscous drag of up to 11%. Both biomimetic models performed well in disturbance reduction when
compared to the NACA model. This improved aerodynamic surface with reduced drag would decrease the fuel consumption
in aircraft. This computational model would help us to fight the war against global warming.
