Here we would like to announce that the construction work on our 50% Wind Tunnel Facility has been completed on the 27th of November. The building which was named Fuuryuu-sya is one of largest in Japan for model road vehicles. It has the newest facilities and to provide further advantage for the development of racing cars in the 21st century it has all the equipment necessary for future experiments we can forsee at this stage. This facility also has the newest security system so that clients may use this facility without worry of their secrets being stolen. ■The Facility in Detail Structure The structure uses steel plates(9mm thick) and steel frames for the horizontal flow Gottingen Type Wind Tunnel. By completely housing this in the building we expect stable wind temperature for the experiments and lower noise effecting the surrounding environment. Data Acquisition Area With a width of 2.75m and a height of 2.5m there is enough area in the cross section for 50% F1 racing car models or similar vehicles. With a length of 8m we are also capable of experimenting with tandem vehicle configurations as well. Main Fan This is an axial flow fan and is capable of producing stable winds of up to 60 m/s. Compression Area With a large compression ratio of 8:3 we are able to achieve stable airflow and uniform temperature distribution. Cooling System Capable of sustaining a temperature of 25 plus minus 3 degrees centigrade with the wind flow at 45m/s, the cooling system for this facility has ample capacity for stable measurement. Moving Belt(Rolling Road) Underneath the measurement area is the Moving Belt(or Rolling Road). It has a width of 2m and a length of 5.5m and has a vacuum system. The maximum belt speed is 60m/s to match the maximum wind speed and has the fastest speed in Japan. The boundary layer suction unit lies just in front of the belt. To enable experiments with a yaw angle of plus minus 5 degrees the whole belt system is on a turn table. There are also tyre arms to suit this type of experiment. Model Support The model will be put on a unit with an upper and lower strut(or sting). The strut system is in turn supported by the solid stage on top of the measurement area. The stage is capable of supporting models in tandem configuration and the strut is capable of accomodating piping and wiring required for air intake and exhaust experiments. Measurement We have decided to use an internal balance. This system is the newest of it's kind and is capable of measuring 3 axes of forces, pitch, roll and yaw moments and is also capable of ride height control. Data Acquisition The system has automated data acquisition and processing software enabling quick and accurate experiments. ■Additional Facilities Measuring Room Located right next to the Moving Belt System, the layout itself is stepped to allow for easy viewing. The all-glass wall between the Measuring Room and the Measurement Area together with the large doors allow for easy viewing and ease of use. Together with the three large overhead monitors, CAD facilities with Pro/E or Catia there are ample facilities to enable efficient experimentation. Assembly Room From the functional layout of the toolboxes and working surfaces to the layout machines and surface plate which are indispensable for the preparation of accurate model adjustment and assembly and further to the storerooms located next door, the Assembly Room can be said to be amply equipped. The bright spacy interior should add some comfort to hard work required during the experiments. Others The Meeting Room with it's audio visual capabilities the Work Shops with the machine tools support the various other activities required together with experiments are also provided. |
