Abstract

Research and aerodynamic testing of BLP-500 and BLP-25 have been conducted in both subsonic and supersonic wind tunnel. Aerodynamic characteristics such as Cl, Cd, and Cm for these types of bomb we obtained. By knowing the aerodynamic characteristics, the stability and trajectory of the bomb can be determined. Both analytical calculation and real tests in the wind tunnel were performed and compared. The results showed that for its static stability, the location of the centre of gravity of BLP-500 and BLP-25 to be less than 115.1 cm and 31.9 cm respectively.

Abstract

Telah dikembangkan metode penentuan parameter awal rotor turbin angin sumbu vertikal tipe Savonius. Dengan daya dan kecepatan angin tertentu, maka kisaran luas, diameter, tinggi, dan kecepatan putar rotor dapat diketahui. Luas rotor sangat dipengaruhi oleh koefisien daya, cP. Kecepatan putar rotor rancangan dapat dihitung setelah diameter rotor dihitung dan Tip Speed Ratio ditentukan. Penelitian ini menggunakan harga koefisien daya (cP), Tip Speed Ratio (TSR), dan rasio diameter terhadap tinggi rotor (D/t) masing – masing 0,1 ; 0,8 ; dan 0,8. Hasil metode ini berupa tabel daya, kecepatan angin, luas rotor, diameter, tinggi serta kecepatan putar, dapat digunakan sebagai rancangan awal turbin angin Savonius bagi para pemula maupun bagi yang awam tentang turbin angin namun ingin membuat, karena turbin angin Savonius dapat dibuat secara sederhana.

Abstract

The type of material used in the fabrication of wind turbine blade is a very important factor so that it will not exceed the allowable maximum deflection. An analysis is conducted to study this deflection effect to that power output and as case study, a 7.6 m blade of 10 kW LPN 10000 E turbine is used. Several assumption as such as deflection due to wind speed at perpendicular to local plane local blade are diameter blade and direction of aerodynamic at aerofoil plane local blade are considered. The distribution of blade deflection along the twisted span is assumed uniform. Calculation is performed for the polynomial order of 2,3 and 4, with variety of deflection of 0.2 m, 0.5m, 1 m and 1.5 m. for design wind speed of 9 m per s it was found that for 0.5 deflection, the losses of 6 percent, 9 percent and 12 percent for blade shape polynomial order 2,3 and 4 consequentively are produced; whereas for 1.5 m deflection, losses are 46 percent, 53 percent, and 56 percent for the same polynomial shape. If a maximum loss of 10 percent is taken, then the max allowable deflection is 0.5 m. Keywords: Defleksi, Sudu, Turbin angin, Keluaran daya, Rugi-rugi.

Abstract

In an effort to improve flow condition and flow speed up to 50 m per s inside LAPAN Subsonic Wind Tunnel, an existing power system and turbine has to be redesigned. Specifications for these requirments have been determined and calculated for the required power and aerofoil type and their dimensions. A method based free vortex design was used to get optimal result. The optimization result produced a turbine with 3 m diameter, with 10 blades, 1.5 m hub diameter. A D RAF PROPELLER aerofoil type was used to produce 230 HP power and 1824 Nm torque, with an efficience 89 percent. This result was considered both technically and economically.

Abstract

Identification of whether aerodynamic performances of a rotor blades has met the criteria according to its design or not, the general procedure is to fabricate and perform a field testing; or testing its model in a windtunnel. Both method require high cost however; therefore, a simulation method using Fluent software had used for obtaining lower cost. The model used in an LS (1)-0417 Mod airfoil having 3 blades and rotor diameter 7.21 m. Simulation test shows a good result with a difference of 4.61 percent for torque and power from design result. Keywords: Sud, Turbin angin, Fluent.

Abstract

An economical electric-small-scale wind turbine is intended for an alternative source of energy for fishermans. For the power requirment of wind turbine with the wind condition in Indonesia, an aerofoil research is needed, in particular for the case of SKEA Nelayan Nila 80, with unknown aerofoil data. The focus of the research concentrated on finding aerodynamics characteristic Cl, Cd and Cm for angle of attack regime from 4 to 16 degrees. The result would be used in the modification of existing wind turbine. With limited engineering data, several integrated softwares had been used such as AutoCad 2004, Gambit and fluent 5.2.1 AutoCad was used to digitise aerofoil geometry, gambit was used for grid generation wich then fed into Fluent 5.2.1. for load analysis. The result was quite similiar to N-60 which gives stall angle at around 13 degree-15 degree and Cl per Cd maximum equal 16.

Abstract

Research on variations of angle of attack turbine blade has been conducted to investigate their correlation with windturbine performances, and for these purposes, AEROFOIL LS (1)-0417 MOD has been selected with 4 angle variations. The first variation is selscted with constant slipstream, the second with Cl max of 0.3, while the third and fouth variations with Cl max of 0.5 and 0.7 respectively. Based on blade element and momentum theory for obtaining efficiency, the following results for all the four variations are 18.15 percent, 16.46 percent, 16.15 percent and 16.26 percent. Hence, it can be concluded that, a highest efficiency is obtained with a constant slipstream as in case 1. In practice, to achieve such configuration, a more accurate blade fabricantion process is required to obtain the highest efficiency. Keywords: Sudu, Sudut serang.

Abstract

A method for determining design characteristics of a wind turbine rotor has been developed. Given the desired power and operational wind speed, the approximate design diameter and rotor rpm can then be determined. The size of the rotor diameter is governed by the blade performance, in which is normally given as power coefficient Cp; designed rotor spedd can be known after calculating the tip spedd ratio. Using this method, the blade and rotor characteristics can be designed quickly as a preliminary design parameter. Keywords: Rancangan awal, Koefisien daya, Tip speed ratio.

Abstract

Structure of the LPN 10000 E wind turbine blade has been manufactured and its structural analysis to find out the strenght of this structure during its operation has also been conducted. The method of aero bending moment and centrifugal bending moment and load has been used while neglegting frcitional and torsional load. The analysis is obtained for composite blade strengthened by high strength carbon unidirectional reinforcement composite. With safety factor of 1.3 minimum, it was concluded that the blade is strong enough to use at its designed operational load.
