Abstract

PurposeThus, in this work the goal is to design, simulate and optimise a holder of a brushless motor in lattice structure to get the best performance in terms of mechanical strength, vibration absorption and lightness.Design/methodology/approachNowadays, most manufacturers and designers' goal are to sell efficient products in mass to keep up or outrun competition. Medical, aeronautical, automobile and civil engineering sectors produce complex parts and products that encompasses multiple properties such as lightweight, energy absorbance, vibration reduction and stress resistant. Studies found that lattice structures are more and more useful in these fields since their characteristics satisfy complex behaviour.FindingsThe study's outcome suggests that the use of lattice structure reduces 60% of the actual motor holder mass while keeping the strength of the material, meeting initial specifications.Research limitations/implicationsThe Ram capacity of the PC.Practical implicationsLight materials for aerospace engineering elongate the range of the unmanned aerial vehicle (UAV) to an extra range of flight.Social implicationsSituation awareness of the country border using surveillance drone and minimising the consumption of fuel.Originality/valueThe research allowed reducing 60% the actual holder mass.

Highlights

Nowadays, vibrations are present in almost all mechanical systems if these systems have parts that translate and rotate with each other
This study consists of designing a holder allowing to fix the brushless motor to the fuselage of an aeroplane
The study’s main goal is to reduce the mass of the holder while maintaining its capability to resist to mechanical forces as well as vibrations caused by the motor which have revolutions per minute (RPM) of 10,000

Summary

Introduction

Vibrations are present in almost all mechanical systems if these systems have parts that translate and rotate with each other. In aviation, the vibrations produced by aeroplane’s engines or rotors in propeller plane can sometimes cause problems for the avionics systems (electronic system), the loss of thrust or be uncomfortable for passengers They can cause a bumpy and loud flight and increase part fatigue in the aircraft, which can cause excess in maintenance and accidents as shown in the following article (Laurent, 2019). The study’s main goal is to reduce the mass of the holder while maintaining its capability to resist to mechanical forces as well as vibrations caused by the motor which have revolutions per minute (RPM) of 10,000. This mass reduction will allow the plane to have more flight autonomy. The full terms of this licence may be seen at http://creativecommons.org/licences/by/4.0/ legalcode
