“…Figure 1 shows the blade element of a propeller with the corresponding aerodynamic forces and velocities. Static thrust is the thrust generated by the propeller when the aircraft is in a stationary condition [9]. To obtain the thrust of a propeller, the static thrust test was carried out using the bench test method [10].…”

The Serindit V-2 is a flying vehicle (UAV) that was successfully developed to participate in the Indonesian Flying Robot Contest with a mission to fly at high speed and acceleration. The purpose of this research is to obtain the optimum aerodynamic performance of the propeller and its effect to the flight performance of the Serindit V-2 Unmanned Aerial Vehicle (UAV). The study began by testing the aerodynamic performance of propellers (static thrust value, time consumed, and power consumed) with different sizes of propellers, ranging from 8 inches to 12 inches. From the test results, the 12-inch propeller at 100% throttle generates the highest thrust value of 29.607 N, time consumed of 4.91 minutes, and power consumed of 717.57 Watt. The study was continued by calculating the flight performance with the results that the maximum speed value was 24.11 m/s, the rate of climb was 3.347 m/s, and the stall speed was 14.6 m/s. Finally, the Serindit V-2 UAV was tested to fly using a propulsion system with a 12-inch propeller and varied throttle opening from 50% to 100%. The test results show the vehicle's maximum speed of 24,562 m/s is obtained at a throttle opening of 100%. The climb rate and the flight time at 100% throttle opening is 2,656 m/s and 3 minutes 27 seconds, while the vehicle's stall speed during cruising flight (angle of attack at 1 degree) is 13 m/s. The difference between the theoretical calculation results and the actual test is at least caused by 2 factors. The first is the aerodynamic factor, in theoretical calculations, the overall aerodynamic design of the aircraft is considered very smooth/seamless. This has an impact on the fluid flow that occurs on the aircraft. On the actual conditions, the vehicle has several parts that cause drag, such as the pitot sensor located at the tip of the right-wing, and the ballast located on the left-wing.

PurposeThe aim of this research paper is to design a motor holder in order to minimize the weight of the motor and to reduce its vibrations causing noise pollution.Design/methodology/approachTo meet the requirements of the purpose the use of cellular lattice structures is ideal. Lattice structures ensure both low mass and high strength. Moreover, their absorption properties are relatively interesting concerning the attenuation of vibrations.FindingsThe result of this paper shows that lattice structure can answer to the need of different fields such as aeronautics in the design of lightweight structures which are strong with a low mass. Indeed, the weight of the final structure of the holder is 0.92 g and its safety factor is 5.1 which met the requirements.Research limitations/implicationsThe limitations of the research paper were the RAM capacity of the computer.Social implicationsTo minimize the weight of the holder in a patroller or a plane is to reduce the consumption of fuel. Moreover one of the reasons of optimizing the vibrations is to reduce noise pollution.Originality/valueThis paper is directed to students, designers who want to know more about the use of lattice structure and more precisely honeycomb sandwich structure.
