Unmanned Aerial Vehicle adalah pesawat yang tidak membutuhkan operator manusia didalamnya. Salah satu faktor desain yang penting dalam perancangan UAV adalah bentuk geometri dari pesawat tersebut. Pada daerah sayap pesawat yang memiliki panjang yang terba... see more

In order to maintain the competitive advantage of the medium short take-off and landing transport aircraft, the task must be solved of ensuring take-off and landing on the ground runways with a length of 600?800 m when installing a turbojet engine.Wh... see more

Winglet attached on the tip of aircraft wings to increase lift. Mainly, winglet used for increasing aerodynamic efficiency, it decreases induced drag caused by vortex on wings tip. The phenomenon of vortex is collision of high-pressured air below the wing... see more

In this paper, the efficiency of the vertical-axial wind power plant   at various wind speeds depending on the angle of attack of the rotor blades was investigated. The object of the investigation was a three-bladed Darrieus rotor. During the mo... see more

In flapping underwater vehicles the propulsive performance of harmonically sinusoidal heaving and pitching foil will be degraded by some awkward changes in effective angle of attack profile, as the Strouhal number increases. This paper surveys different a... see more
