Introduction

The development of lightweight drone quadcopters has seen exponential growth owing to their applications in surveillance, delivery, agriculture, and recreational activities. A pivotal challenge in drone design is to minimize weight to maximize efficiency and flight duration while ensuring adequate payload capacity. This project focuses on creating a simple, lightweight quadcopter that meets the operational constraints specified, including size, weight, and environmental considerations. Literature suggests that optimizing component weight, choosing standard parts, and ensuring ease of maintenance significantly enhance drone performance and longevity (Chen et al., 2018; Wang & Huang, 2020). The integration of protective seals for environmental exposure and accessible maintenance panels forms a core part of the design philosophy, emphasizing sustainability and practical usability.

Design Concept and Methodology

The drone's core design revolves around a modular, robust frame constructed from lightweight materials such as carbon fiber or aluminum alloys, compliant with the dimension constraints of 150mm to 300mm radius from the center to the rotor shaft. The overall weight balancing is achieved by strategic placement of the battery pack at the center, aligning with the mass of the propulsion system, which includes imported brushless motors and compatible rotor blades sourced from reputable suppliers.

The rotor blades are designed to operate efficiently at 2000 rpm, powered by motors capable of delivering the required thrust while maintaining minimal weight. The threading of the input shaft (5 mm diameter) is catered for by standardized fasteners, ensuring compatibility with off-the-shelf components. Protective seals are incorporated around all exposed electrical and rotating parts using IP-rated enclosures to withstand environmental challenges such as dust and moisture. The entire assembly is designed with maintenance accessibility in mind, with removable cover plates secured with standard fasteners, facilitating repairs and component replacements.

Assembly Drawing and Major Component Detailing

The detailed assembly drawing illustrates the placement of key components: the central battery compartment, four arms extending outward to support the rotor assemblies, landing skids, and protective covers over electrical elements. Each arm is designed with standardized fasteners for easy assembly and disassembly. A major component, such as the motor and rotor blade assembly, is detailed with precise dimensions, tolerances, and surface finishes, ensuring proper fit, minimal vibration, and optimal aerodynamic performance.

Material Selection and Components

Material choices prioritize lightweight yet durable options such as carbon fiber composites for the frame and aluminum or plastic for protective covers. The motors are imported from established suppliers like DJI or T-Motor, which provide specifications aligning with the design criteria. Batteries are selected based on capacity-to-weight ratios, ensuring a balance between payload and flight time, with considerations for thermal management and safety.

Environmental Protection and Maintenance Features

All exposed electrical connections and rotating components are sealed with rubber or silicone gaskets to prevent ingress of dust and moisture, complying with IP ratings suitable for outdoor environments. The removable cover plates are designed with standard fasteners and gaskets, enabling maintenance access without compromising environmental sealing when reassembled. The drone's design promotes ease of repair, with clearly accessible components and modular assembly, reducing downtime and facilitating repairs.

Impact on Society and the Environment

The lightweight drone design promotes environmental sustainability by reducing energy consumption and manufacturing resource usage. Its application in environmental monitoring and disaster management exemplifies positive societal impact, providing a tool for data collection without causing ecological disturbance. The use of environmentally friendly materials and efficient electrical systems further enhances the drone's social acceptability and environmental footprint, aligning with the principles of sustainable engineering (Elgin et al., 2017; Zhang & Liu, 2019).

Conclusion and Recommendations

The proposed design successfully balances weight reduction, payload capacity, environmental protection, and maintenance accessibility within specified operational constraints. Future enhancements could include integrating sensors for autonomous navigation, exploring alternative energy sources like solar cells for extended flight times, and utilizing advanced lightweight materials to further reduce weight. Emphasis on modularity and standard parts simplifies manufacturing and repairs, promoting wider adoption and use in various applications.
