Abstract

This paper describes numerical simulation o f flexible High Altitude Long Endurance Unmanned Aerial Vehicle (HALE UAV)wingusing two-way fluid structure interaction (FSI) method. The HALE wing is designed with high aspect ratio. This configuration intended to reduce the vehicle induced drag and reduces the lift-loss at wingtip which caused by wingtip vortex. But the structure of the wing itself becomes more elastic that be able to give large deformation when the aerodynamic loads applied. This deformation changes the aerodynamic loads distribution on the wing that gives a new deformation to the wing structure and vice versa. This interaction in a couple process called as fluid structure interaction (FSI). ANSYS 15.0 software was used to simulate fluid structure interaction on the wing. The unsteadiness and viscous flows at low speed are evaluated using the solution o f timedependent Reynolds Averaged Navier-Stokes (RANS) with SST k-rn turbulent model. In addition, multiblock structured grids are generated to provide more accurate viscous result and to anticipate negative volume o f the mesh which may occur due to the deformation o f the wing during simulation. Five different o f simulations are performed with variation o f material characteristics including Young’s modulus and Poisson’s ratio.The results are global aerodynamic characteristics at various material characteristics.

Abstract

Potential flow over an airfoil plays an important historical role in the theory of flight. The governing equation for potential flow is Laplace’s equation, a widely studied linear partial differential equation. One of Green’s identities can be used to write a solution to Laplace’s equation as a boundary integral. Numerical models based on this approach are known as panel methods in the aerodynamics community. This paper introduces the availability of a computational tool for constructing numerical modelfor potential flow over an airfoil based on panel methods. Use of the software is illustrated by implementing a specific model using Hess and Smith panel method to compute the flow over a member of the NACA four-digit airfoils.

Abstract

The wind speed gauge in a wind tunnel plays an important role in the airflow simulation process so that it is similar to the actual conditions as desired. Wind speed measurement in wind tunnel mostly use manometer with special fluid (red manometer fluid) and the resulting data is in the form of analog data. The red manometer fluid is unavailable in Indonesia and its price is quite expensive so it becomes a challenge for wind tunnels that still use manometer. Therefore, it is necessary to make a new instrument for measuring wind speed that is easy to use by utilizing materials that are easily obtained but still apply the same measurement principles as a manometer in measuring wind speed in wind tunnels. The design of the wind speed measuring device can take advantage of microcontroller technology. The wind speed sensor design process goes through three stages including hardware design, software design, and system design. The hardware used for the system are an Arduino Uno R3 microcontroller, a differential pressure sensor MPXV7002DP, and an LCD. Research results obtain a wind speed sensor that can be used to measure wind speed in a low subsonic wind tunnel based on Bernoulli's principle that utilizes a pitot tube with a maximum speed of 30m/s. The wind speed sensor is an Arduino-based design that can display the wind speed measurement results on the LCD screen. The wind speed sensor was declared valid to be used to measure wind speed because there were no deviations from the wind speed measurement when compared to the measurement results from a calibrated anemometer.

Abstract

EDF is an electric propulsion consists of a duct, fan, and electric motor with the motor power source coming from a battery which creates compression air for thrust. The design and configuration of an EDF is not complicated as a jet engine, but it could generate high thrust for highspeed flying like highspeed UAV needs. The preliminary design of an EDF yields a design and performance estimation. The design needs validation by experimental tests for real performance data. The test needs test tools and EDF itself. The aim of this research is experimental testing of an EDF for real performance data as validation of the existing design. The performance test is done by EDF test bed hence the manufacturing process of EDF is done by 3D printing. Test results show differences in performance of EDF with estimation results by analytical approach. The thrust of EDF from the experimental test is lower than the estimation calculation from the preliminary design, so the EDF does not fill the design criteria yet and needs refinement design.

Abstract

In aviation, electric propulsion has long been applied, one of which is the electric ducted fan (EDF). In Indonesia, initially, EDF was mostly used for the propulsion of aeromodelling aircraft for hobby purposes. LAPAN initiated the use of EDF as a drone propulsion which flown since 2013. In addition, EDF is also used in the Indonesian Rocket and Rocket Payload Competition (KOMURINDO). KOMURINDO is an annual competition for the design of rocket payloads and Electric Ducted Fan (EDF) rockets at the university level which has been held by LAPAN since 2009. In the EDF rocket competition, EDF is a secondary part of the competition because it is not required to design and build so the participants prefer products ready to use all of which come from abroad. This limits the participants in designing the EDF rocket because, in the design, the EDF specifications must be following the initial design requirements specified. Therefore, this research needs to be carried out as a first step in understanding the design process for the development of EDF. The fan is the main part of the rotating EDF or also called the rotor. Fan plays a vital role in generating thrust through accelerating airflow, so it is necessary to design to produce a fan that suits your needs. The design method used in this research is a combination of the thrust equation for the rotor and the blade element theory. The CFD method is used to analyze the performance of the designed fan which is compared with the experimental test results with the EDF test bed. The results of the design obtained that the EDF fan geometry which produces a thrust based on CFD analysis is much smaller than an initial estimate using the analytical method, it is necessary to carry out an optimization process in the process of determining the fan geometry with a better method so that the resulting thrust is following the initial estimate. The results of the EDF test show that the thrust produced by the EDF is smaller than the results of the CFD analysis, this can be due to the less optimal distance between the fan tip and the duct wall on the EDF being tested due to manufacturing results, causing the appearance of a tip vortex which reduces fan performance. In addition, the flow resistance of the duct surface is not smooth due to the manufacturing process. The CFD method can be the first step to determine the performance of the fan or EDF before proceeding to the prototype testing process because the CFD results are close to the test results.

Abstract

The vertical axis wind turbine (VAWT) with helical-blade has been developed, manufactured and applied in almost all developed countries. In Indonesia, vertical axis wind turbines are still not widely applied compared to horizontal axis wind turbines. Vertical axis wind turbines with helical-blade are still very rare in Indonesia. Research and development of the vertical axis wind turbine are needed because of its advantages compared to horizontal axis wind turbine. The advantages are: can operate in various wind directions, lower noise due to smaller tip speed ratio (TSR) and for large-scale, mechanical and electrical systems of turbine can be placed on ground. The aim of this research is to design a vertical axis wind turbine rotor with helical-blade that can be applied at low speeds and changing direction wind condition, such as urban wind characteristics. Performance analysis of wind turbine rotor is done by using double-multiple stream-tube (DMS) model approach. This research yields a rotor of vertical axis wind turbine with helical-blade with rotor length and diameter are 2m and 1m respectively, the rotor blade airfoil is DU-06-W-200 with chord length is 0.2m. From analysis, the optimum tip speed ratio of the rotor is 2.6 with a maximum power coefficient is 0.57.

Abstract

Entrepreneurship is one of the main focuses of Karang Taruna’s activities in an effort to improve community welfare. Karang Taruna in Jaden Village, Mranggen, Jatinom, Klaten, offers a variety of programs that the community can participate in. However, aeromodeling has not yet been included as part of the development activities in Karang Taruna of Jaden Village, Mranggen, Jatinom, Klaten, due to a lack of knowledge and information about aeromodeling, even though Klaten is very close to the Adisutjipto Airport and the Indonesian Air Force Base, both of which frequently hold aeromodelling events and activities. A training program on making simple aeromodelling planes, such as foam chuck gliders, could become a source of independence and a foundation for further understanding of aeromodelling, which has the potential to develop into a wider business field. In this training, the OID (Observe-Imitate-Do) method is applied to accelerate and strengthen the learning process. The results of the training demonstrate the effectiveness of the activity through indicators such as: participants showing great enthusiasm in following the entire program, as evidenced by their active participation and high level of involvement in all activities, the application of the OID method providing effective and comprehensive learning experiences for the participants, and the training successfully sparking participants’ interest in exploring entrepreneurship.
