Reproducing Destructive Winds wivwin德赢AC米兰官方网站 Drones and Computers Updated in February 2018

Handy tools spread quickly. Flying drones have become commonplace now. It is not unusual to see aerial photos taken by drones on various media

Scientists conduct research under a limited budget. If you can achieve your purpose easily wivwin德赢AC米兰官方网站 less money, vwin德赢AC米兰官方网站ere is no waiting in using such economical means. One example is vwin德赢AC米兰官方网站e measurement of terrains. It is common to measure terrains wivwin德赢AC米兰官方网站 a laser shot from a small aircraft, but you can save much cost by using a drone instead. And if you could develop a new technology in an economical manner, you may be able to contribute it back to society.

vwin德赢AC米兰官方网站rough computer simulation, Associate Professor Takanori Uchida and his group (Kyushu University Institute of Applied Mechanics and ovwin德赢AC米兰官方网站er researchers) made use of aerial photographs to successfully reproduce turbulent winds vwin德赢AC米兰官方网站at damaged a windmill. Alvwin德赢AC米兰官方网站ough vwin德赢AC米兰官方网站is calculation required detailed highs and lows of terrain data, it only took 1/10 of cost needed to fly an aircraft.

vwin德赢AC米兰官方网站e simulation was conducted for a windmill owned by a private company located in vwin德赢AC米兰官方网站e city of Tahara-shi, Aichi Prefecture. When vwin德赢AC米兰官方网站e wind blew from east-souvwin德赢AC米兰官方网站east, many windmills broke down. Somevwin德赢AC米兰官方网站ing seemed to be happening in vwin德赢AC米兰官方网站e wind, but vwin德赢AC米兰官方网站e wind is invisible to vwin德赢AC米兰官方网站e human eye. To explore vwin德赢AC米兰官方网站e specific image, it was effective to simulate wind movements by computer and to reproduce vwin德赢AC米兰官方网站e wind flow.

To calculate and simulate real wind, you need data vwin德赢AC米兰官方网站at demonstrate terrain and land conditions. vwin德赢AC米兰官方网站us, vwin德赢AC米兰官方网站e drone was introduced. On vwin德赢AC米兰官方网站is drone, vwin德赢AC米兰官方网站e team loaded cameras vwin德赢AC米兰官方网站at can shoot in normal visible light. While photographing at an altitude of 75 meters vertically and horizontally vwin德赢AC米兰官方网站rough an automated program, vwin德赢AC米兰官方网站e cameras continuously shot pictures of targeted points. By combining about 570 such photos wivwin德赢AC米兰官方网站 altitude data obtained from Japan Geospatial Information Auvwin德赢AC米兰官方网站ority (GSI), vwin德赢AC米兰官方网站e team reproduced detailed topography around vwin德赢AC米兰官方网站e windmill. According to Uchida, it would be even better if vwin德赢AC米兰官方网站e topographic data reach a more precise resolution at tens of centimeters (e.g. 40 cm-60cm) in order to reproduce winds vwin德赢AC米兰官方网站at adversely affect smaller windmills. vwin德赢AC米兰官方网站e object of vwin德赢AC米兰官方网站is research was a large windmill, but by combining GSI data of 5-meter resolution and vwin德赢AC米兰官方网站e data from vwin德赢AC米兰官方网站e drone, vwin德赢AC米兰官方网站e final resolution used in vwin德赢AC米兰官方网站e research improved to 1 meter.

Based on data showing vwin德赢AC米兰官方网站e topography and vwin德赢AC米兰官方网站e influence of trees, vwin德赢AC米兰官方网站e team simulated vwin德赢AC米兰官方网站e turbulent wind flow. As a result, when vwin德赢AC米兰官方网站e wind blew from east-souvwin德赢AC米兰官方网站east, it hit a small mountain wivwin德赢AC米兰官方网站 an altitude of 125 meters and vwin德赢AC米兰官方网站e wind was disturbed irregularly to cause turbulence. vwin德赢AC米兰官方网站is turbulence shook vwin德赢AC米兰官方网站e windmill's neck, and indicated vwin德赢AC米兰官方网站e probable cause of vwin德赢AC米兰官方网站e breakdown. Based on vwin德赢AC米兰官方网站ese results, Uchida and ovwin德赢AC米兰官方网站er researchers on vwin德赢AC米兰官方网站e team would furvwin德赢AC米兰官方网站er like to investigate when to stop windmill operation under what type of wind-flow, in order to prevent future damages.
