Abstract

Quadrotor is a rotorcraft that has four rotors, usually symmetrical and arranged in some specific configuration, i.e. ‘plus’ and ‘cross’ configuration. To test a new control system for quadrotor, it is necessary to put it on board first and have a flight test. However, controlling a quadrotor is a hard task, hence the risk of crash is high. This risk can be reduced by creating a simulation model that represents the dynamics of quadrotor accurately. This paper aims to provide the simulation model of a quadrotor. To increase accuracy of this model, the disturbance induced by the motion of the quadrotor were also taken int account. The simulation was built in Simulink based on the kinematics and dynamics equation of quadrotor both in linear and nonlinear simulation. In most cases, the attitude response (roll, pitch, and yaw) for both simulations were nearly the same. The most notable difference was for the elevation response in which the linear simulation tended to be unable to capture the deviation, while the nonlinear simulation was able to.

Abstract

Penggunaan wahana udara tanpa awak (UAV) yang semakin meluas mendorong perkembangan perancangan propeler modern ke arah peningkatan performa dan pengurangan tingkat kebisingan. Studi pada winglet propeler dan propeler tipe toroidal dilakukan secara numerik CFD untuk membandingkan gaya dorong, daya dan efisiensinya dengan propeler biasa / konvensional APC 20x10.  Simulasi CFD dilakukan dengan metode Frozen Rotor dan Periodik Rotasional pada putaran 3000 RPM dan 5 kecepatan aliran. Hasil simulasi menunjukkan propeler winglet justru mengalami penurunan efisiensi sebesar 1% dan penurunan gaya dorong sebesar 5% sedangkan propeler toroidal menunjukkan peningkatan efisiensi 6% walaupun gaya dorong turun 10% dibandingkan propeler biasa. Propeler toroidal juga memiliki distribusi tekanan yang lebih merata sepanjang bilah yang mengindikasikan tip vortex yang sangat rendah. Studi pengaruh variasi rancangan winglet atau toroidal terhadap pembentukan tip vortex dan performa propeler dapat dikembangkan lebih lanjut untuk mendukung pengembangan UAV yang ramah lingkungan.
