Description

The invention relates to shipbuilding and for the construction of fully inflatable vehicles with outboard engine. Known inflatable motor boats traditionally contain an inflatable balloon of a closed or horseshoe-shaped type along the contour, bow, stern, bottom and transom mounted on the stern bulkhead connecting the two sides.

From the current level of technology there are known technical solutions for two types of frameless inflatable motor boats with a stationary transom for an outboard motor, which are made as follows:

- the first view - a classic frameless inflatable motor boat with a stationary transom and remote control, consists of a horseshoe-shaped inflatable board of various configurations and sizes, an inflatable or rigid floorboard of various designs with or without a keel, the floorboard is glued along the perimeter of the side, and a transom for fastening outboard motor of various configurations, glued into the board and floor, remote control unit, the crew is placed either on inflatable seats or on banks (a transverse board fixed between the side s), or directly on the bottom ceiling. The design forms a closed loop having an internal volume, providing rigidity and carrying capacity of the vessel;

- the second type - a motor boat of a frameless type catamaran layout with a stationary transom and remote control, consists of two parallel load-bearing inflatable balloons of various configurations and sizes, a floorboard of various designs of an inflatable or rigid type connecting both cylinders glued along the perimeter of the side, a transom for mounting a suspension motor of various configurations, glued into the board and floor, remote control unit. The crew is placed either on inflatable chairs or on banks (a transverse board fixed between the sides), or directly on the floor. The design forms a closed loop having an internal volume, providing rigidity and carrying capacity of the vessel.

An inflatable boat is known from the prior art, comprising a U-shaped main balloon, bow, aft with a transom and a bottom attached to the main balloon, bow and stern, while the boat is supplemented by a block of three independent cylindrical cylinders interconnected throughout the length with the help of flexible fabric hinges, and in the stern with a common overlay, while the lower cylinder block and the main cylinder of the body are interconnected by gluing with the bottom and mechanical fixing of the block overlay to the transom of the body (RU 81469 U1 March 20, 2009).

An inflatable boat is also known, including an open contour of the A-shaped sides of the plan, a transom and a keel-shaped inflatable bottom attached to the sides in their lower part and consisting of the lower and upper sheets of elastic material, interconnected around the perimeter with the formation of a trailing rounded edge inflatable bottom, while the transom is mounted on the rear rounded edge of the inflatable bottom so that the rear surface of the transom coincides with the rear edge of the edge of the inflatable bottom (RU 146255 U1, 10.10.2014).

The disadvantage of all the above designs of inflatable boats is the inconvenience of operation, low level of comfort, insufficient rigidity of the hull as a result of low speed, low safety of the vessel and poor seaworthiness.

The task to which the claimed technical solution is directed is to increase operational characteristics.

The technical result achieved by using the invention is to increase ease of use, increase comfort, increase the rigidity of the hull and increase seaworthiness, creating the possibility of extreme driving and safety. This invention is a vehicle, opening a new class of inflatable ships "inflatable jet ski with a stationary transom for an outboard motor."

The technical result is achieved by using the following set of essential features, namely: an inflatable jet ski with a stationary transom containing a central carrier balloon and a U-shaped side balloon, while one end of the central carrier balloon located on the side of the bow of the jet ski is pointed and beyond the perimeter of the side balloon, and the other end, from the side of the stern, is animated, and an engine transom is attached to it on stringers; along the jet ski, between the central carrier cylinder and the side cylinder, two sections of the floorboard are attached with internal partitions at an angle to the supporting cylinder, while the bearing and side tanks, as well as the floor sections, can be interconnected by air channels that can be inflated simultaneously the whole body of the jet ski.

In the particular case of the invention, on the central carrier cylinder, in the upper part, there are two fins - front and rear, between which the crew is placed when moving. In the underwater part of the side balloon, at its ends, there are cutoffs.

The invention is illustrated graphic materials: Fig. 1 is a side elevational view of the jet ski; FIG. 2 is a rear view of the jet ski; FIG. 2a is a front view of a jet ski, where: 1 is an onboard balloon; 2 - the central bearing cylinder; 3 - section payola; 4 - two cutoffs (left and right); 5 - axial stringer mounting transom; 6 - installation site of the fuel canister; 7 - engine control unit; 8 - transom; 9 - fin front and rear.

An inflatable jet ski contains a hull, which is a U-shaped board in the form of an onboard balloon with a raised nose, a central bearing balloon and a transom. The hull is made according to the axial diagram of the vessel in the form of a central carrier cylinder with two pneumatic wings, which is formed by a side of variable cross-section and a payola with a raised nose (400-600 mm above the waterline) and has a significantly long slope to the water plane (20-40 degrees) along axis for a smooth approach to the wave and air intake to form a dynamic air cushion.

The casing contains an onboard cylinder framing a central carrier cylinder. The central carrier balloon is located under the side cylinders in the bow of the jet ski and protrudes beyond the perimeter of the side balloon by 30-80 cm, forming an elongated nose. One end of the central carrier cylinder, located on the side of the bow of the jet ski, is pointed, and the other end, on the side of the stern, is animated.

The sections of the floor are located between the central carrier cylinder and the side cylinder, form a pneumatic wing. The floor consists of inflatable, narrow sections ranging in size from 200 to 400 mm in width and from 1900 to 2300 mm in length, has internal partitions directed at an angle to the carrier cylinder. The floor sections are placed symmetrically on the sides of the axis of the central bearing cylinder.

The central bearing and side cylinders, as well as the floor sections, can be interconnected by air channels made with the possibility of simultaneous inflation of the entire body of the jet ski.

In parallel with the carrier balloon, two inflatable payols of variable cross section, bordered by an onboard balloon, are actually formed, forming two pneumatic wings. At the ends of the on-board balloon, cut-offs are located below, which ensure that the incoming air flow is kept under the bottom, forming a dynamic pillow. On the bottom of the vessel, the supporting balloon and the side balloon actually form three guides, forming two channels for compressing the incoming air flow during movement, to ensure easy gliding. The transom is adjustable and attached to the axial stringers, located symmetrically along the central bearing cylinder at the mounting point of the floor.

The inflatable jet ski is equipped with a stationary transom for an outboard motor with remote control, power up to 50 hp, it is possible to manufacture a transom with the ability to adjust the height remotely.

The crew is mounted on a central carrier cylinder. Also, two front and rear fins can be placed on the carrier cylinder to facilitate the safety of extreme driving. The jet ski is controlled by a standard steering remote control unit for an outboard motor, both a water jet and a propeller.

The combination of essential features provides a fundamentally new way of forming the hull. The presence of a central bearing cylinder significantly increases the rigidity of the hull, which fundamentally changes all the operational characteristics of the vessel. An increased axial twisting load is provided. The use of the above arrangement of the sections of the floor significantly increase the protection against shock load from the side wave and provides stable gliding. Placing the crew on a carrier cylinder using fins helps to increase safety, axial balance and directional stability and, as a result, increase the maneuverability and safety of the vessel.

The device works as follows: a standard outboard motor is attached to a transom of a special design, fixed to stringers on a central carrier cylinder, a portable fuel canister is placed immediately after the transom in front of the central carrier cylinder, the standard remote engine control is located in the nose on a special panel with a device for adjusting the angle tilt steering, the pilot and passengers are mounted on a central bearing cylinder between two fins.

According to the author, the claimed technical solution meets all the criteria for patentability of the invention and is a new class of watercraft.
