Multirotor vehicles propulsion systems are based on the assembly of a (usually fixed pitch)
propeller with an electric motor, powered by a battery pack. Resulting endurance and range …

Aerodynamic characteristics of commercially available off the shelf propellers for smallscale
multi-rotors have been discussed. Six-axis force and moment measurements have been …

Drones are nowadays becoming more and more common. This paper presents a way to
improve their performance and increase their versatility based on a faster design and …

Unmanned Aerial Vehicles (UAVs) have become one of the most promising technologies in
our days due to their outstanding autonomous capabilities, versatility and flexible operation …

The wide spreading market of unmanned aerial vehicles (UAVs) is requiring more and more
performing flying platforms. For rotary wing systems, especially multicopters, the leading …

At early stages of design, where the airplane layout is not established yet, a large spectrum
of aircraft configurations remains being a design alternative. In this way, the large amount of …

The high-power density and good scaling properties of electric motors enable new
propulsion arrangements and aircraft configurations. This results in distributed propulsion …

This paper deals with the design and the implementation of experiments for the performance
characterisation of the main power devices of the hybrid propulsion system of a lightweight …

A large part of small-sized UAVs that are used for surface scanning, video-and photography,
or other similar applications are of the multirotor type. These small aircraft perform mainly in …

This paper presents an analytical framework for addressing the hovering performance of a
battery–powered multirotor. The estimation of power required for flight is investigated and an …
