TL;DR: In this article, the authors presented a less complex and simplistic way to do all the calculations of all vital parameters needed for building any drone, and the theoretical validation of the equations which are derived and mentioned in the paper with the practical data obtained from the prototype built.
Abstract: Drone are now commercially used in almost every industry from delivery to defense, general people also make them for hobbies, but due to lack of clear open source information, new enthusiast and even the existing one find it very difficult to build it on their own without any professional help. This paper presents a less complex and simplistic way to do all the calculations of all vital parameters needed for building any drone. This paper presents the theoretical validation of the equations which are derived and mentioned in the paper with the practical data obtained from the prototype built. The analysis of each parameter is done very precisely to make the mistakes as low as possible. All the equations which are mentioned have some assumptions and use of standard values, which is clearly mentioned with the work. The prototype built is an autonomous system containing six rotors and communication modules for sending data on the ground. The conclusion of the paper shows the difference in the accuracy between theoretical values calculated from the derived equations and what practical testing gives.

TL;DR: This work tries to evaluate multicopter sizing process for performance targets, and finds that, there are different ways to maximize endurance time.
Abstract: We present a conceptual approach for multicopter sizing and performance analysis. Our conceptual approach allows users to choose the multicopter components, and evaluate flight performance of the chosen configuration. Weight model of our approach is induced by regression equations of parameters of multicopter components such as BLDC motor, propeller, battery and airframe. In addition, propulsion model is developed through modification of momentum theory for propeller diameter, pitch, and rotating speed. We try to evaluate multicopter sizing process for performance targets, and find that, there are different ways to maximize endurance time

TL;DR: In this paper, the authors focused on how the weight and thickness of the multicopter power wires affects the flight time keeping in mind that flight time is directly related to the weight of the multi-rotor.
Abstract: a multicopter is a coaxial flight system using two or more spinning propellers. This paper is focused on how the weight and thickness of the multicopter power wires affects the flight time keeping in mind that the flight time is directly related to the weight of the multirotor. A high diameter wire can lower the energy loss but will increase the weight of the system resulting shorter flight time. The author had developed an application who analyze the multirotor configuration and give a graphical estimation of the best wire to use.

TL;DR: The test results in the study showed that communication system built on multi quadrotor had been done and there is conformity between AR.Drone 1 and AR.drone 2.0.
Abstract: A quadrotor is one of Unmanned Aerial Vehicle that has a capability to flight in the restricted area. Quadrotor as the flying robot attracted the interest from various groups such as researchers, hobbyists, and military for doing particular tasks. Although a single quadrotor is capable of overcoming multiple missions, however, a multi quadrotor has advantages for overcoming communication failures. Multi quadrotor in its application is identical with a formation that required leader-follower, behavioral structure, virtual structure, multiple-input-multiple-output approaches for communication between quadrotor. In this study, communication system and multi quadrotor established using AR.Drone 2.0. A study of a formation based on connection has made by AR.Drone. Wi-Fi communication types designed as the communication which is subsequently tested with various flight movements to study the responses that obtained from each AR.Drone. The test results in the study showed that communication system built on multi quadrotor had been done. There is conformity between AR.Drone 1 and AR.Drone 2 motion due to navigation data is taken from a roll, pitch, and yaw parameters.

TL;DR: In this paper, a test rig for the identification of the propulsion subsystem and control system design for small unmanned aerial vehicles (UAV) helicopter type is presented. And the test rig can be used for identification of drives with variable step propellers, which requires the additional channel for swashplate control.
Abstract: The article is devoted to the parameter's identification of the propulsion subsystem and control system design for small unmanned aerial vehicles (UAV) helicopter type. Parameter's identification is realized with a special test rig developed by authors of the project, the description of which is presented in the article. The designed test rig application is the parameter's identification of power systems with fixed step propeller. The test rig can also be used for identification of drives with variable step propellers, which requires the additional channel for swashplate control. The measurements are static and dynamic characteristics of the propulsion subsystem and can be used for computer model design and verification. The parameters identification results can be used to develop control systems for UAV control systems propulsion systems of the UAV. Moreover, UAV control system performance allows it to keep stable flight and execute various tasks. To debug and tune control system gimbals test rig was designed. The gimbals test rig has a capability to research various control system behaviors without probable injuries of untuned subsystem UAV.

TL;DR: In this paper, the flight and sensor performance of a multicopter mini unmanned vehicle is analyzed, and the authors aim to deeply analyze the flight, sensor, and battery performance of the mini-UAV.
Abstract: Multicopters have started to be easily obtained and widely used. Even many people are trying to build them by themselves. However, since a multicopter is a dynamical system with many parameters and many sensors on it, the proper controller PID tuning or correct matching of right propeller, weight, motor and battery is complete engineering problem and if a good multicopter in means of good stability and good “handling qualities” is wanted to be built than good understing of PID tuning, sensor reading and motors and propellers is necessary. In this study we aim to deeply analyze the flight and sensor performance of a multicopter mini unmanned vehicle.
