Facilities and Equipment in Yokosuka Headquarters

Multipurpose experiment tank


  1. The tank
    This tank is provided with ferro-concrete walls, one side of which has five one-meter square viewing windows for observing underwater motions of the experimental model.
    Dimensions:40m (length) × 4m (width) × 2m (depth)
  2. Gauge trolley
    The gauge trolley slides over the tank. A variety of models can be attached to the trolley. Running the trolley at different speeds allows monitoring and analysis of characteristics such as water resistance to various motions.
    Item Explanation
    Model Analog uniaxial two-wheel drive
    Speed 0.2~2.0m/s
    Acceleration rate within ±3%F・S


Tests of flow and wave effects on various marine structure models
Tests of the kinematic characteristics of mobile underwater objects
