TSL-F Test Ship HAYATE
A largest-scale test ship of a hydrofoil-type hybrid ship (TSL-F) named HAYATE was completed in Kobe Works of Kawasaki Heavy Industries, Ltd., and various at-sea tests were conducted in 1994.
Features
1. HAYATE which is a 1/6 scale test ship of an R & D objective TSL-F ship, is composed of an upper hull, a fully submerged lower hull which bears buoyancy, fully submerged foils which generates dynamic lift, and struts which connect the upper hull and the lower hull or the foils.
2. The main propulsion system of HAYATE consists of a water jet propulsor, a reduction gear and a gas turbine.
3. When HAYATE starts to take-off, the dynamic lift generated by the foils is added to support the total load and the upper hull clears out of the water.
When cruising in foilborne condition maintaining the required air gap between the sea surface and the upper hull bottom, HAYATE can avoid the influence of waves because only very thin struts pierce the sea surface.
4. Thus, TSL-F represented by HAYATE has extreme seaworthiness with almost no speed reduction or undue motion in high sea navigation.
Furthermore, the automatic control system can keep the ship's motion exceptionally stable due to very small buoyancy change and less water surface influence in foilborne condition.
5. Various at-sea tests of HAYATE were conducted in 1994 to acquire data unobtainable through laboratory tests and to evaluate and verify the overall performance of TSL-F as well as numerous fundamental research findings.
