“…The additional weight of the shroud is a major disadvantage of shrouded rotor systems as the aerodynamic benefit is penalized by the additional thrust requirement to carry the shrouds. Kuantama et al [13] demonstrated the use of CFD to analyze shrouded and open rotor configurations. The study compared different shroud geometries with the aim to minimize the total weight of the shroud.…”

A novel approach for the rapid design of unconventional rotor shrouds combining a rapid manufacturing approach with a high-fidelity CFD prediction tool is proposed in this work. Using 3D printing and thrust stand measurements, different shroud designs have been explored experimentally to evaluate the performance gains of propeller shrouds for multirotor vehicles with small-scale, off-the-shelf propellers. The experimental studies are complimented with 3D quasi-steady CFD simulations to gain further insights into the flow fields for unconventional shroud geometries. The framework has been demonstrated for a commercial 5-inch racing-drone propeller, featuring significant performance gains using NACA-shaped shroud profiles.

Ducted propeller is an engineered propeller drive which aimed to enhance thrust force. Many ways can be done in purpose to enhance thrust force, such as geometry variation in term of Ld/D ratio. Ld/D ratio is a ratio between duct length and duct diameter. In this research, an analysis was conducted using numerical simulation. This research used two Ld/D ratio (0.4 and 0.5) and three propeller angular velocities as the variables (1000, 3000, and 5000 rpm). The result of this research showed that higher Ld/D ratio produced higher thrust force. At 5000 rpm the thrust fore increased 26.3% on duct with Ld/D ratio of 0.5. Moreover, higher propeller angular velocity produce higher fluid velocity at the ducted propeller outlet. The highest fluid velocity reached at 5000 rpm propeler angular velocity with the value of 9.8 and 10.8 m/s.Keywords: ducted propeller; Ld/D ratio; numerical simulation; thrust force

The subject of the study is the characteristics of the quadrocopter propeller. The object of the study is a two-blade propeller of a quadrocopter. The aim of this study was to evaluate the efficiency, acoustic characteristics of the propeller of a quadrocopter and optimize the angles of laying out carbon fiber with minimization of deflection. To achieve this goal, the following tasks were solved: simulation of the flow in a two-blade propeller of a quadrocopter in a given range of rotation frequencies; calculation of the efficiency of a two-blade propeller of a quadrocopter; calculation of the level of acoustic pressure of the studied propeller; and calculation of the deflection of a two-blade propeller of a quadrocopter at different angles of carbon laying out. The study of the flow in the propeller was carried out using the method of numerical experiment. The calculation for the deflection was carried out on the basis of the aerodynamic characteristics of the propeller using the method of a numerical experiment. The level of acoustic pressure L was estimated at 1 m from the source of acoustic radiation (screw). Results: the optimal mode of operation with a maximum efficiency is observed at a speed of 9000 rpm. and reaches a value of 0.853. At the minimum investigated speed of 3000 rpm. The propeller efficiency has the lowest value and is 0.638. With an increase in the speed of the rotor of the engine, the efficiency of the propeller gradually increases. With the increase of rotational speed from 9000 rpm. up to 10000 rpm. the efficiency decreases from 0.853 to 0.833. Estimation of the level of acoustic pressure of the studied two-bladed propeller showed that the rotation frequency had a significant effect on the level of acoustic pressure of the propeller. With an increase in rotational speed from 3000 rpm. up to 10000 rpm. propeller acoustic pressure-level increases from 56.62 dB to 90.57 dB. The calculation results showed that the deflection of the propeller blades under study depends on the laying angles of the carbon fiber layers. Blade deflection varies from 0.76 mm to 0.821 mm. The greatest deflection of the blades was achieved with the option of laying out layers of carbon fiber 0°/30°, the smallest - at angles of 0°/80°. The scientific novelty and practical significance of the conducted research is that new data on the characteristics of a two-blade quadrocopter propeller have been obtained. The data obtained will help create and optimize the parameters of a two-bladed quadrocopter propeller.
