Small-unmanned aerial vehicle propellers usually have a low figure of merit due to operating in the low Reynold’s number region due to their size and velocity. The airflow on the airfoil becomes increasingly laminar in this region thus increasing the profile drag and consequently reducing the figure of merit of the rotor. In the article, the airfoil geometries are parameterized using the Class/Shape function transformation. Particle swarm optimization is used to design an airfoil, operating in a Reynolds number of 100,000, which has a high lift to drag ratio. To avoid exceeding geometric constraints of the airfoil, a deterministic box constraint is added to the algorithm. The optimized airfoil is then used for a preliminary design of a rotor; given some design, constraints on the tip chord the rotor radius and the blade root chord, with parameters that achieve the highest theoretical figure of merit. The rotor parameters are obtained using a combination of momentum theory and blade element theory. The figure of merit of an optimal propeller with the same geometric parameters is then compared using the optimized airfoil and the Clark Y airfoil. The optimization is done in MATLAB while the aerodynamic coefficients are obtained from XFOIL. The results of the numerical simulation are presented in the article.

Aviation is becoming more and more popular. It is influenced, inter alia, by the development of general aviation (GA) and unmanned aerial vehicles (UAV). Due to the increasing number of qualified UAV users (in April 2018 there were 6846 operators in Poland with a valid certificate of qualifications) and those performing only recreational flights, it is important to ensure an acceptable level of risk in these operations. Using the available methods, the risk of five exemplary unmanned operations was assessed. The results were compared to determine their validity.
In connection with the rapid development of commerce of unmanned aerial vehicles (UAV), the optimality of their use with UAV companies (UAVCo) is becoming increasingly important. The basis of such companies are mobile units (mobile units (MU)), which include UAV, means of their delivery to the place of rendering services and maintenance personnel. A problem of determining the optimal level of orders for the use of MU with UAVCo has been formulated and solved. The task is formulated as an overbooking task. The process under investigation is described as a discrete-time Markov chain corresponding to 24 hours. Based on a fixed number of MU and a fixed overbooking level, distributions for the number of orders on hand, the number of unfulfilled customs, and the average income with an MU usage fee and penalties for unfulfilled orders factored in have been calculated. The solution method has been tested on a particular model. For calculation used language and computer environment MathCAD.

Commercially available drone type unmanned aerial vehicles (UAV), as well as parts and subsystems enabling the assemble of UAVs, are becoming more and more widely available, and their performance is constantly improving. The current possibilities of a drone assembled by a hobbyist predispose are not only to be used as a reconnaissance tool but also as a guided missile. The use of a camera with a video stream transmitter simultaneously with virtual reality goggles and video stream receiver gives the pilot an impression of being on the drone, which makes it possible to control it with extreme precision, even at high speeds. The article presents research aimed at determining the extent and type of damage made on exemplary racer drone caused by intense microwave field radiations.
