@techreport{oai:jaxa.repo.nii.ac.jp:00043426, author = {平岡, 康一 and Hiraoka, Koichi}, month = {Sep}, note = {KHI (Kawasaki Heavy Industries) CFD system is composed of VP100 computer and 2 and 3 dimensional Euler/Navier-Stokes (NS) analysis. For KHI, this system has become very powerful aerodyamic tool together with the Kawasaki 1-Meter Transonic Wind Tunnel. 2-D Euler/NS software, developed in-house, is fully automated, requires no special skill, and was successfully applied to the design of YXX high lift devices and SST supersonic inlet, etc. 3-D Euler/NS software, developed under joint research with National Aerospace Laboratory (NAL), has an interactively operated Multi-Block type grid generator and can effectively generate grids around complex airplane shapes. Due to the main memory size limitation, 3-D analysis of relatively simple shape, such as SST wing-body, was computed in-house on VP100, otherwise, such as detailed 3-D analyses of "ASUKA" and "HOPE", were computed on NAL VP400, which is 10 times more powerful than VP100, under KHI-NAL joint research. From a total efficiency point of view, NAL is expected to always keep a computer mare than 10 times powerful than those of aircraft industries. These analysis results have very good correlation with experimental results. However, the present CFD system is less productive than wind tunnel and has applicability limitation. Further improvement is required for both software and hardware. To lead this improvement, NAL is expected to have a supercomputer which can solve unsteady NS analysis of a complete airplane. This will require 100 times more power than that of VP400., 資料番号: NALSP0013003, レポート番号: NAL SP-13}, title = {川崎重工業のCFDに対する取り組みと将来展望について}, year = {1990} }
