In this paper, a numerical analysis of a biomimetic unmanned aerial vehicle (UAV) is
presented. Its wings feature three grids at the tip similar to the primary feathers of birds in …

The wing tip device in this study was to mimic the wing tips of a soaring bird, featuring three
smoothly blended elements. Each such multi-element winglet was integrated into a …

Birds can reduce the induced drag using an elongation of the wings called primary feathers.
In this paper, a numerical analysis of a biomimetic Unmanned Aerial Vehicle (UAV) that …

One of the most important factors affecting the aerodynamic performance of the aircraft is lift-
induced drag caused by wingtip vortices. This study describes the winglet design and …

An unmanned aerial vehicle (UAV) is an unmanned aircraft that can be controlled remotely
or flown automatically. Nowadays, the use of UAVs is extensive, not only limited to the …

Various configurations for airplane wing tip winglets have been investigated by performing
3D aerodynamic analysis. An existing blended winglet has been equipped with a secondary …

Metrologi adalah disiplin ilmu yang mempelajari metode pengukuran, kalibrasi, dan
ketelitian baik dalam bidang industri, ilmu pengetahuan, maupun teknologi di masa depan …

This study aims to compare two small-sized axial fans: one is the classic axial fan (referred
to as" Model A") and the other is an innovative design using the natural pattern of the …

A global multiobjective design optimization method is introduced for optimizing three-
dimensional geometries based on topology optimization. To validate the method's …

Airfoil is an aerodynamic model that is widely used both on aircraft wings, Unmanned Aerial
Vehicle (UAV) and fluid machines such as pumps, compressors, and turbines. The airfoil on …
