“…UAV and related technologies are developing quickly with more and more efficiency and currently, the main limitation of UAV multirotor is energy (batteries). However, as the following papers show [57,58], these problems are being addressed by several research groups. Our research does not depend on the crop field size.…”

This article describes the technical specifications and configuration of a multirotor unmanned aerial vehicle (UAV) to acquire remote images using a six-band multispectral sensor. Several flight missions were programmed as follows: three flight altitudes (60, 80 and 100 m), two flight modes (stop and cruising modes) and two ground control point (GCP) settings were considered to analyze the influence of these parameters on the spatial resolution and spectral discrimination of multispectral orthomosaicked images obtained using Pix4Dmapper. Moreover, it is also necessary to consider the area to be covered or the flight duration according to any flight mission programmed. The effect of the combination of all these parameters on the spatial resolution and spectral discrimination of the orthomosaicks is presented. Spectral discrimination has been evaluated for a specific agronomical purpose: to use the UAV remote images for the detection of bare soil and vegetation (crop and weeds) for in-season site-specific weed management. These results show that a balance between spatial resolution and spectral discrimination is needed to optimize the mission planning and image processing to achieve OPEN ACCESS Remote Sens. 2015, 7 12794 every agronomic objective. In this way, users do not have to sacrifice flying at low altitudes to cover the whole area of interest completely.

“…Following the original sizing approach by Raymer [8] for fixed-wing aircraft, the empirical trends from the market survey subsequently drive the mass sizing and loading aspects of the design phase. In this work, however, we follow the modifications in [9] to adapt the original sizing methodology to multirotor UAVs as shown in the flowchart in Fig. 3.…”

“…Raymer's theory for fixed-wing aircraft [8]. Starting from Raymer's traditional aircraft sizing methodology [8], Gatti and Giulietti [9] developed a sizing technique for electric M-UAVs through market trends of existing commercial drones. Since most multirotor drones are powered electrically, the traditional method developed for fuel-powered vehicles has been adjusted to replace the fuel mass with a constant battery mass which does not decrease over the flight duration.…”

“…This work proposes a design methodology for heavy-lift M-UAVs starting from Raymer's theory [8] and its extensions to multirotor vehicles in [9]. The novel sizing technique is tailored towards compact vehicles with coaxial propulsion systems suitable for delivery applications in urban settings, and accounts for the aerodynamic deficiencies of coaxial rotors.…”

This work presents a novel design methodology for multirotor Unmanned Aerial Vehicles (UAVs). To specifically address the design of vehicles with heavy lift capabilities, we have extended existing design methodologies to include coaxial rotor systems which have exhibit the best thrust-to-volume ratio for operation of UAVs in urban environments. Such coaxial systems, however, come with decreased aerodynamic efficiency and the design approach developed in this work can account for this. The proposed design methodology and included market studies have been demonstrated for the development of a multi-parcel delivery drone that can deliver up to four packages using a novel morphing concept. Flight test results in this paper serve to validate the predictions of thrust and battery life of the coaxial propulsion system suggesting errors in predicted flight time of less than 5 percent.

This paper addresses the need for sizing of rotors for multirotor vehicle applications such as personal air transport, delivery, surveillance, and photography. A methodology for the propeller and motor selection is developed and augmented with flight time estimation capabilities. Being multirotor-specific it makes use of the platform’s simplicity to rapidly provide a set of off-the-shelf components ready to be used in the vehicle. Use of operating points makes the comparison process fast, precise, and tailored to specific application. The method is easily implemented in software to provide an automated tool. Furthermore, clearly defined input and output parameters make it also usable as a module in other multicriteria optimisation algorithms. The new methodology is validated through comparison with a consumer-grade drone and the calculated results are compliant with manufacturer’s specification in terms of maximum hover time.
