摘要

Research analyses extensive optimizations of UAV frame structures for multi-rotor vehicles by studying aircraft aerodynamics with structural materials and deployment requirements. This work explores four drone models through mathematical evaluation of Tri-copters, Quadcopters, Hexacopters and Octocopters. The research analyses the structural strength properties and weight distribution parameters, along with evaluating aerodynamic performance through a carbon fibre, aluminium alloy, with polyamide nylon composite analysis. Force platforms gain their strength from efficient power consumption and quick handling across various operations, but payload carrying abilities and stability benefits come from drones beyond four and six rotors. The combination of environmental conditions, together with wind speed variations and payload mass, results in noticeable modifications of power usage efficiency and flight time while affecting stability performance. The study of materials selection determines that carbon fibre delivers better weight reduction than polyamide nylon or aluminium composite materials. The research brings essential engineering data about UAV frames for establishing improved performance, which benefits safety operations and delivery systems.
