Reliability calculation with error tree analysis and breakdown effect analysis for a Quadcopter power distribution system

Abstract

Today, quadcopters play an important role in a variety of industries due to their many advantages over other aircraft. In addition to their high level of technology, quadcopters are susceptible to damage, and their repair can be costly. On the other hand, today, reliability is recognized as a critical design feature in most industries. A device's reliability is one of the most important issues in the field of engineering since it provides engineers with an insight into how a device performs. The reliability of a system is one of the most important and complex issues. Since reliability is a key factor in all industries and can have significant effects on increasing the life and quality of products, we tried to use reliability using statistical relationships and mathematical models as well as past experiences. Due to their reliability, cost-effectiveness, and multifunctionality, they are frequently used in a variety of locations Then, by examining the failures modes and their results on the system, the effects of the quadcopter failures are analyzed using the FMEA method, in order to determine the modes and causes of failure. Finally, to determine the causes of failure, we have checked the quadcopter by FTA method to minimize the possibility of failure. The purpose of this article is to first discuss definitions and concepts in the field of reliability and then to analyze the quadcopter and its components.
