A sizing tool for the preliminary design of an unmanned aerial vehicle for student projects

A general procedure of preliminary design of aircraft and one-way fluid-structure interaction (FSI) applied to aircraft design is introduced briefly. Then, FSI and optimization technique are implemented to optimize a wing shape of an unmanned aerial vehicle (UAV) for minimum cruise drag. FSI analysis and optimization processes for minimizing drag of UAV are explained. Design variables are wing taper ratio and dihedral angle, and objective function is the cruise drag of UAV. Fluid solution is generated with Euler solver and structural analysis is performed with FEM solver, Diamond. Sample points are selected by Design of Experiment (DOE) method and Kriging method is used for generation of an approximation model.

Main Components

Applications involving the use of alternate, renewable energy sources are expanding exponentially, and are in high demand. Solar power has long been harnessed for such applications and aviation is no stranger to it with its strong drive towards becoming an environment-friendly industry. This paper describes a straight forward procedure to design and test a solar powered unmanned aerial vehicle that can fly continuously for 24 hours at any day of the year. The paper introduces the modeling and preparation of hardware testing of the propulsion and power sub-system. The main components of this sub-system are solar panels, the electromechanical drive train and the propeller. A design for a thrust stand to measure the performance of the system is also introduced.

The problem of selecting a propeller-driven power plant including a single propeller and a piston engine for an aircraft taking into account the requirements for community noise is considered. The competitively necessary community noise levels for light propeller-driven aircraft are formulated, focusing on which it is necessary to design modern aircraft that meet the current and future requirements of ICAO. Modern noise reduction technologies are considered and their effectiveness is evaluated. The main parameters when choosing a propeller are its diameter, the number of blades, the configuration (pusher or tractor) and the presence of a duct. When choosing a piston engine you should take into account the higher acoustic efficiency of two-stroke engines compared to fourstroke engines. The use of intake and exhaust mufflers, as well as sound-proofing hoods, significantly affects the mass and size restrictions, so the need to install mufflers and hoods should be determined at the preliminary design stage. The design mode for the design of light propeller-driven aircraft is the take-off power condition, for propeller unmanned aerial vehicle is maximum cruising level flight mode.
