Description
Technical field
The utility model relates to a kind of trimarans, belong to hybrid high performance vehicle technical field.
Background technique
Displacement 100~600 tons, design speed 40~50 sections high-speed craft, because speed is higher, overall cost compared with
It is low, thus be all widely used at two aspect of military and civilian.Such high-speed craft is between displacement ship and glider
Between a kind of ship type, referred to as transition ship type.For conventional monomeric ship type in order to meet transverse stability requirement, length-width ratio is typically small, because
And the wave making resistance and Added Resistance in stormy waves are larger, it is poor in the economy of transition stage and safety.Trimaran
Type be exactly be to solve limitation of the single ship body in high speed and occur.
The main hull length and width of trimaran are bigger, are slender bodies structure, and length-width ratio is generally more than 10, the design of main hull front
For sharp cone distal, wave making resistance and Added Resistance are smaller, but transverse stability is insufficient.To enhance its transverse stability, in main hull two sides
The bigger small side hull of two length-width ratios is added, due to the displacement very little of side hull, the main function to trimaran is exactly
The transverse stability for enhancing trimaran influences very little to other performances of trimaran.But conventional tri-body ship type also has its limitation, such as ship
Body is elongated, and in the identical situation of displacement, wetted surface is larger, and then causes frictional resistance larger；For another example slender bodies is vertical
Damping is smaller, thus the rocking tendency in wave is also larger, and pitch metacentric stability is poor.
Patent CN201710403681.X, CN201710190920.8, CN201610343848.3 etc. propose to use hydrofoil
Resistance is reduced, hydrofoil can be lifted hull in high speed, reduce hull and water body contact area, to reduce resistance.Due to
The situation of ship under sail is changeable, and fixed hydrofoil adaptability is poor.The hydrofoil of the variable angle of attack can solve problems, by automatic
Control system constantly adjusts its angle of attack according to parameters such as sea condition, hull posture, speed, accelerations, to obtain different move
Lift, but this structure is complex, and processing cost is high.It is not mentioned in these patents and how to improve longitudinal stability.
