Abstract - A Quadcopter is a sophisticated mechatronic
logistics, and surveillance. The study addresses the lack of comprehensive research comparing traditional 3-blade propellers to toroidal designs, particularly in terms of thrust and efficiency. This sets the foundation for the research objectives, which include a detailed analysis of both propeller types using advanced simulation tools to optimize their performance.
device characterized by complex dynamics, relying on controlling six degrees of motion using thrust generated by propellers driven by DC motors. The primary objective of this study is to conduct a comprehensive thrust force analysis comparing a conventional three-blade propeller with a toroidal propeller, assessing the thrust force generated by each design under varying angular speeds and velocities.
The problem statement emphasizes the need for improved propeller designs to meet the rising demands for UAV efficiency and performance. While conventional propellers are widely used, they may not always provide optimal thrust or efficiency under varying conditions. The study seeks to address this gap by comparing the aerodynamic and performance characteristics of conventional and toroidal propellers, particularly under different operational scenarios. The research will use advanced 3D modelling and fluid flow simulations to analyse the propellers and provide practical insights for propeller design in UAV applications.
To achieve this, 3D CAD models of both the three-blade conventional propeller and the toroidal propeller were meticulously designed using Onshape software. These models were then imported into SimScale software for fluid flow simulation, where the aerodynamic characteristics over the propellers were analysed under different angular speeds and free-stream velocities. The simulation data provides insights into how each propeller design affects thrust force generation and overall efficiency. Additionally, this study evaluates and compares the efficiencies of both propeller types. Efficiency metrics consider factors such as thrust force output relative to power input. By systematically comparing these aspects across various operating conditions, the study aims to highlight the performance advantages and potential drawbacks of each propeller design in diverse flight scenarios.
The significance of the research lies in its potential to advance UAV technology by offering data-driven insights into propeller dynamics and performance. By focusing on both conventional and toroidal designs, this study aims to guide future propeller selection and optimization for various UAV applications. The scope includes designing and simulating propellers using CAD and CFD software, followed by an evaluation of thrust, efficiency, and potential design improvements, contributing to the development of more efficient UAV systems across diverse industries.
This outlines a structured approach to quantify and analyse the thrust force capabilities of conventional threeblade propellers versus toroidal propellers using SimScale software. The findings are expected to contribute to advancements in propulsion technology, improving the efficiency and effectiveness of aerial vehicles, marine vessels, and industrial machinery.

Key Words: 3D CAD models, Aerodynamic characteristics, Angular speeds, Conventional threeblade propeller, Efficiency, Fluid flow simulation, Onshape software etc
The design process for the 3-blade conventional propeller begins by setting up a project in Onshape, ensuring consistent units of measurement for accurate modelling. The overall dimensions are defined, with a propeller diameter of 6 inches (152.4 mm) and a pitch of 4 inches (101.6 mm). The initial geometry is created by drawing concentric circles on the top plane to form the hub and blade base, followed by extruding these shapes to establish the blade profiles and hub geometry.
