Design of a quad copter to reduce energy consumption

초록

Background/Objectives: In recent years, as interest in the drones has been increasing worldwide, it has been used in various fields. We propose a quadcopter to reduce energy consumption. Methods/Statistical analysis: We investigated and analyzed the flight principles of the drones, especially the quadcopter. Generally, the quadcopter rise vertically up to a certain height from the ground and then move forward. In addition, to apply the paragliding principle as a way to increase the flight time of the quadcopter, we investigated the paragliding that can fly without any power and applied it to the quadcopter. Findings: Because of its small size compared to manned aircraft, lithium-polymer batteries are mainly used as a power source for the quadcopter. But flight time is not long due to limitations of battery capacity. Therefore, it is necessary to reduce the energy consumption in the operation of the quadcopter. In this paper, we have tried to reduce energy consumption of the quadcopter and apply paragliding method which can fly without any power. The overall structure of the quadcopter can be divided into a sensor part, a control part and an operation part. In the sensor part, an accelerometer gyro sensor is used for attitude control. The control part processes the sensor value received from the sensor part and transmits the result to the operation part. It requires the fast processing. The operation part consists of four BLDC motors for operating the quadcopter, two servo motors for switching to the paragliding mode and two servo motors for rotating two BLDC motors in order to move the quadcopter forward in the paragliding mode. Improvements/Applications: We propose a hybrid type quadcopter that can fly in a paragliding mode to reduce energy consumption. It is possible to improve the overall energy efficiency by reducing battery usage. © 2018, Institute of Advanced Scientific Research, Inc. All rights reserved.
