“…The rotors are mounted under the fuselage and pusher propellers are used. This approach increases flight times of multicopters by several percent as shown in Zabunov and Mardirossian (2018). Another novelty is the positioning of 16 rotors in an optimal geometric coverage.…”

“…A single cell has rated capacity in the range of 3 Ah and its nominal voltage is 3.6 V. This results into an energy capacity of is 10.8 Wh per cell or 21.6 Wh in total can be expected. Having data from earlier experiments (Zabunov and Mardirossian, 2018), the total required power for flight shall not exceed 35 W. This is a predicted value that includes the motors and the avionics power requirements and it strongly depends on flight conditions, weather, type of payload, etc. According to this predicted figures the flight time is expected to exceed 37 mins – quite adequate for many mission scenarios.…”

“…This method of designing the rotors' positions on the airframe has been already successfully implemented in a 12-rotor multicopter model (Zabunov and Mardirossian, 2018). Another innovation in the current design is the mounting of the rotors under the airframe (fuselage) with the help of pusher propellers.…”

Purpose The current manuscript aims to propose a novel multirotor design. Design/methodology/approach This paper presents a novel 16-rotor multicopter design named Emerald. The novel design innovations and benefits are disclosed. Comparison to existing 16-rotor designs is carried out. Implementation areas where the novel idea shall yield benefit are discussed. A prototype of the presented design is described. Findings The herein proposed 16-rotor design has a number of benefits over existing 16-rotor multicopters. The paper elaborates on those advantages. Research limitations/implications The research was limited to prototype testing, as the presented design is a novel concept. Practical implications The motivation to research and develop this novel design is implementing the vehicle for stereoscopic photography and reconnaissance. The design is also applicable to carrying payloads while flying indoors.

Nowadays, the use of multi-propellers has been increased, because of some basic advantages such as vertical take-off and landing, simple mechanical structure. In addition, different usage fields such as carrying an object and making video records over the cities. This paper exposes design and control of two different multi propeller systems and both systems have 12 rotors to carry more load. In first, all motors are arranged at identical angles in the same plane. In the other, the motors are mounted in two groups, eight and four in two different planes, the lower and upper. Flight performances of these two different UAVs were compared under disturbing effect. It was observed that the flight performances were close in the simulation study. Although the average and maximum of the position errors for three axes in the first model was less than the other, for the same propeller dimensions, the first model must have larger dimensions than the other in the context of the smallest vehicle dimensions.

“…The importance of multirotor aircraft has increased significantly during the recent years and the need for innovations is becoming well pronounced (Zabunov and Mardirossian, 2018). Except multirotor aircraft, fixed-wing drones also have significant applications in a number of areas and require innovations in accord with the development of the modern electronic technologies.…”

Purpose This paper aims to reveal the authors’ conceptual and experimental work on an innovative avionics paradigm for small unmanned aerial vehicles (UAVs). Design/methodology/approach This novel approach stipulates that, rather than being centralized at the autopilot, control of avionics devices is instead distributed among controllers – spread over the airframe span, in response to avionics devices’ natural location requirements. The latter controllers are herein referred to as edge controllers by the first author. Findings The edge controller manifests increased efficiency in a number of functions, some of which are unburdened from the autopilot. The edge controller establishes a new paradigm of structure and design of small UAVs avionics such that any functionality related to the periphery of the airframe is implemented in the controller. Research limitations/implications The research encompasses a workbench prototype testing on a breadboard, as the presented idea is a novel concept. Further, another test has been conducted with four controllers mounted on a quadcopter; results from the vertical attitude sustenance are disclosed herein. Practical implications The motivation behind developing this paradigm was the need to position certain avionics devices at different locations on the airframe. Due to their inherent functional requirements, most of these devices have hitherto been placed at the periphery of the aircraft construction. Originality/value The current paper describes the novel avionics paradigm, compares it to the standard approach and further reveals two experimental setups with testing results.
