概要 When launching a space rocket, cross wind is thought to be one of maojor weather hazards since a rocket experiences wind load and drifting. To develop new types of space rocket optimally, it is essent...ial to understand fully about wind around a launch pad and a rocket itself, considering three-dimensional airflow structure. To simulate wind, large-eddy simulation (LES) technique was applied to Tanegashima Space Center and its launch facilities, structures and buildings. In this paper, comparison evaluation is discussed based on the results from LES technique and data acquired by anemometers in 15 years and the Doppler lidar system in a month. The numerical results showed good consistent with the observational data especially in the airflow locally affected by buildings and the topographical effects.続きを見る
