Multi-perspective Investigations of Aerosol’s Non-linear Impact on Unmanned Aerial Vehicle for Air Pollution Control Applications Under Various Aerosol Working Environments

Abstract

The primary focus of this investigation is to create a unique main rotor equipped rotary-wing unmanned aerial vehicle (RWUAV) to detect and mitigate air pollution, which is major concern in modern civilization. This RWUAV was designed after careful consideration and analysis in a variety of maneuvering phases under the fluid particle-based aerosol conditions. This method of spraying the atmosphere using an RWUAV is meant to eradicate fog and other airborne pollutants. The RWUAV takes a mixture of hydrogen peroxide and nitric acid solution, which it then sprays into the air. The aerodynamic parameters are estimated using ANSYS Workbench 17.2 equipped with computational fluid dynamic (CFD) solver, i.e., Fluent and ANSYS Workbench 17.2 with Finite element analysis (FEA) solver has been used to assess the RWUAV imposed with a variety of lightweight materials. The aforementioned multi-computational techniques are used to examine the structural robustness and aerodynamic performances under different airflow circumstances. As the load acting on the proposed RWUAV in aerosol-rich environment will be different than the normal environment, thus the need of this study to determine suitable material which will be structurally stable in both the environments. Thus, from the cumulative results of the structural analyses for both VTOL and forward maneuverings of the RWUAV it can be concluded that for VTOL the materials CFRP-WN-230-wet, CFRP-WN-230-ppg, CFRP-UD-230-wet, CFRP-UD-230-ppg, GFRP-S-UD, and GFRP-E-UD have proven to perform better than other lightweight composites. And from the cumulative results of structural analysis for forward motion the materials CFRP-UD-230GPa-ppg, CFRP-UD-230GP-wet, and GFRP-S-UD have proven to perform better than other lightweight composites. Thus, in conclusion CFRP-UD-230GPa-ppg, CFRP-UD-230GPa-wet, and GFRP-S-UD are better materials for RWUAV for better performance under aerosol heavy environment as these materials have shown promising results for both VTOL and forward motion under both normal environment and aerosol heavy environment. Developing this RWUAV would be helped along by the fact that this RWUAV might be made in a way that is less harmful to the environment.
