Small unmanned aerial vehicles (SUAVs) have found a widespread application in past decades. However, as the criticality of the missions for which they can be used increases, the demand for improvement of their efficiency increases as well. The paper focuses on a propeller driven SUAVs of a multirotor type, equipped with an electric motor, battery and propeller. The paper presents a simplified method of calculation of the SUAV maximal endurance, if the characteristics of all components of the propulsion system are known. To improve the overall efficiency of the propulsion system of an SUAV, the correct combination of all propulsion system components is critical. However, the largest impact on the maximal endurance is, arguably, caused by the propeller. The paper proposes a simple method of optimizing the propeller characteristics for hover and compares the proposed propeller design with conventional and commercially available propellers.

The objective of this research was to develop a process for the design and manufacture of mission- and aircraft-specific propellers for small unmanned aerial vehicles. This objective was met by creating a computer program to design a propeller that meets user-defined aircraft performance requirements within the limitations of the electric motor, user-selected materials, and manufacturing methods. A comprehensive review of prior UAV propeller design and additive manufacturing for small propellers is also presented in this paper. The use of additive manufacturing (3D printing) in making flightworthy propellers was explored through material testing, manufacturing trials, and by testing the propellers under simulated flight conditions in a wind tunnel. It was found that the propeller performance generated nearly the predicted design thrust but the efficiency and power consumption could not be accurately measured with the present test setup. While flight testing was not completed at this time, ground and wind tunnel testing were sufficient to demonstrate the feasibility of producing flightworthy propellers using additive manufacturing.

Abstract The paper proposes an analysis of Unmanned Aerial Vehicles (UAVs) features that enable them to support naval operations in general, but the focus drawn to the Black Sea basin peculiarities in particular. In the introductory part, the authors succinctly present the Black Sea basin’s physical and strategic characteristics. Then, follows a description of UAVs features and potential missions conducted by these types of robots. In the next section, the article presents the uninhabited aerial vehicle classification and system components. The last chapter analyses the efficiencies and vulnerabilities of these vehicles. The closing section gives some short conclusions regarding the suitability of using such assets to support naval operations and a few further research directions..

The design of the propulsion system for Unmanned Aerial Vehicles (UAVs) demands an inclusive multidisciplinary approach from the earliest design phases, since every design choice strictly affects and is affected by the overall working conditions. This paper presents a review of the scientific literature focused on the design methods applied in defining and sizing the propulsion system of drones. The analysis, performed with a systematic approach, evaluated 123 papers according to two custom classification taxonomies, which investigated respectively the primary aim and specific content of the works. Finally, literature indications and hints were combined into an integrated framework for the functional design of the propulsion system of UAVs. The procedure aimed to support the designer in the preliminary selection of the propulsion candidates and the quick sizing of the supply system, during the first phases of the design process. According to the literature, design methods dramatically change depending on the expected applications and working conditions of UAVs, so that the detailed design of specific drone elements and propulsion components represents the focus of most of the papers in this field.
