Definitions

• the invention relates to the field of shipbuilding and relates to the creation of floating facilities for entertainment and sports, in particular, jet ski boats.
• the jet ski boat is designed for short walks.
• the device has several disadvantages.
• the objective of the proposed invention is to improve seaworthiness. device by improving its stability during sharp maneuvers and providing the possibility of sharp dynamic braking by using the reverse mode.
• the technical result from the use of the proposed proposal is achieved in that in a small-sized high-speed two-seater boat-hydrocycle, which includes a hull, a water-jet propulsion device, a reverse-steering device in the form of a rotary reverse valve and a rudder-a rotary nozzle, a control device for its movement associated with the engine and reverse - steering device, the driver and passenger seats are placed on both sides of the diametrical plane (DP) of the hull of the boat-jet ski, outboard, and have the maximum possible low position in relation to the waterline of the boat - jet ski.
• DP diametrical plane
• the device for controlling its movement is located between the said seats and is made mainly in the form of a joystick lever kinematically connected to the steering wheel and to a control system kinematically connecting the engine control and the reversing device.
• the aforementioned control system is designed in such a way that when the joystick lever is tilted from the neutral position to the “forward” position, the reversing device is set to “forward gear” mode, while the engine speed increases proportionally to the movement of the joystick lever, and when the joystick lever is tilted, neutral position to the “back” position, the reversing device is translated into the “rear-drive” mode, respectively, and the engine speed also increases in proportion to the slope of the joystick.
• the connection of the lever-joystick with the steering wheel is such that when it is tilted in one direction, the jet ski boat is turned in the same direction and, accordingly, vice versa.
• driver and passenger seats on the side, on both sides of the DP hull of the boat-hydrocycle at a level close to the waterline allows you to lower the center of gravity of the device, bringing it as close as possible to the waterline, which leads to great confidence in the movement of people on the boat-jet ski their safe TM when maneuvering.
• control device for the propulsion of the boat-jet ski between By the driver’s and passenger’s movements, it makes it possible to control the movement of one or the other person separately, and the driver can also position himself to control the movement with both his right hand and left hand (left-handed person).
• the implementation of the motion control device in the form of a predominantly joystick lever kinematically connected simultaneously with the steering wheel and with the engine control system and the reversing device ensures the availability of active and dynamic control of the jet ski boat to anyone who is not even trained.
• control system of the reversing device and the engine when, when the reversing device is in the “forward or reverse” mode, the engine speed increases, allows you to carry out sharp maneuvers when the boat-jet ski is moving and use the principle of dynamic braking, which provides a significant increase in braking efficiency without waiting jet ski boat stops
• FIG. 1 is a side view of a jet ski boat
• FIG. 2 is a plan view thereof.
• the small-sized high-speed double boat-jet ski has a hull 1, inside of which seats 3 of the driver and passenger are placed side-by-side on the diametrical plane 2, a water-jet propulsion 4, an engine 5, a switchgear 6, a lever-joystick 7 for controlling the movement of the boat-jet ski.
• the jet propulsion 4 includes a water intake 8 and a rotary nozzle 9.
• the switchgear consists of a rotary reverse valve 10 and a rudder, the function of which is performed by the rotary nozzle 9 of the jet propulsion 4.
• the reverse valve 10 has the ability to rotate around its horizontal axis 1 1.
• the lever-joystick 7 of the motion control is located between the seats 3 of the driver and passenger, kinematically connected to the steering wheel 9 and through the engine control system and the reversing device (not shown) with the latter, and has the ability to tilt along and across the DP of the boat - jet ski.
• the device operates as follows.
• the person controlling the jet ski boat tilts the joystick lever to the forward position to start forward, while using the kinematic connections of the control system, the reversing device of the jet propulsion unit is set to the forward position, and the engine starts to gain speed in proportion to the inclination of the joystick lever .
• the joystick lever is tilted to the “back” position, while the reversing device is brought into the reverse position, respectively, and the engine starts to gain speed also in proportion to the inclination of the joystick lever.
• control maneuvering them At any position of the lever-joystick in the direction of movement of the boat-jet ski forward or backward, control maneuvering them.
• the joystick lever When the joystick lever is tilted to the right or left, the jet ski boat maneuvers respectively to the right or left, regardless of the direction of movement forward or backward. Since the control lever-joystick is located between the driver and the passenger, and is the only means of controlling the jet ski boat, any of them can take control during the movement, without the risk of a dangerous situation on the water.
• the joystick lever is abruptly moved completely from the “forward” position to the “backward” position.
• the engine speed is reset, shifting the reversing device to the “rear run” position, after which the engine speed increases.
• the reversing device begins to operate in reverse mode, but the boat-hydrocycle still maintains its forward progression, and it is at this moment that the maximum reverse thrust is created on the mover.
• the boat-jet ski sharply slows down and goes into a displacement mode of movement (it is immersed as much as possible in water) and, due to the increase in the resistance of its hull, the braking is further enhanced. Due to this, the braking efficiency increases many times.
• the joystick lever is moved to the neutral position and the boat-jet ski stops.
• the lower location of the center of gravity of the complex with people allows for such inhibition without risking human life.
• the joystick lever is moved to the “rear run” position and the hydrocycle after stopping starts moving in this direction.
• the inventive small-sized high-speed double boat-jet ski was made in the form of a prototype.
• the presented structural scheme of the boat-jet ski fully confirmed its main advantages over the prototype in terms of controllability.
• the claimed invention allows to create a new small-sized high-speed double boat-jet ski with increased stability during maneuvering.
