The bag can form the external force generated by the air cushion, so that the ship can partially or partially leave the lower support cable surface to sail! Single-purpose air-supported, high-speed surface-mounted air ship, some of which have amphibious performance. The ship relies on air exchange force to balance most of the hull, and a small part of the hull is supported by self-buoyancy. The ship can sail forward off the water surface. It applies the principle of air-raid ship, is supported by air force, and has a two-phase energy platform. It is equipped with a propulsion device, which can lower the self-propelled air cushion without a propulsion device. It is a semi-functional air-controlled air-cushion that is specially designed for non-exploratory operations! Air transport annual service contract

Definition or explanation
The air expansion that can maintain its pressure higher than atmospheric pressure and play the role of supporting the object
The enclosed air cushion near the supporting surface is on the supporting surface. The various shapes of the air cushion surface are simplified to the width of the swept rectangle. The air cushion width of the full-cushion air cushion is the average distance between the two equal ends, the air cushion width of the side wall air cushion is the average distance between the inner waterline of the two side walls, the length of the air cushion surface parallel to the supporting surface, the air cushion resistance of the full-cushion air cushion is interpreted as the circumference of the enclosed air cushion, and the side air cushion is the average vertical distance between the entire inner waterline and the lower edge of the air cushion circumference and the supporting surface. The full-scale air cushion is usually the average vertical distance between the bottom of the buoy and the supporting surface. The air cushion is the ratio of the length of the air cushion to the total width of the air cushion. The ratio of the length of the air cushion to the air cushion speed is the Froude number with the length of the air cushion as the characteristic. In the formula, V is the ship speed, m, y;
average speed, ;
air cushion length, m
The air cushion force acts on the water and makes the water surface directly below the air cushion lower than the plane surface at the point of the search, forming a depression depth. During static rise, the water column pressure is also the same. The question cannot be deduced from the concrete term

In the coordinate system with the single center as the origin, the coordinate of the center of the pressure gauge
The quantity of the entire body of the ship in the lifted state, including the pin or the airtight sealing assembly, including the maximum horizontal separation of the pressure belt perpendicular to the centerline surface of the ship configuration in the lifted state, from the bottom edge of the ship or the lowest surface of the side wall to the uppermost surface of the hull! The air cushion ship has a great momentum. When there is no air cushion, the half water distance between the front end and the end of the ship's main surface is included. When there is no air cushion, the half water distance between the upper surface of the ship and the upper surface of the ship is vertical. When there is no air cushion, the box-shaped hull structure composed of the longitudinal watertight bulkheads is the main force of the whole air cushion. In terms of time, the maximum safety of the outer dimensions of the pontoon structure should be considered in the stock case, the outer dimensions of the pontoon training are too wide, and the height of the ship is small. The outer dimensions of the pontoon structure are small. The height of the pontoon structure is small. The other side of the ship is a kind of non-sale of the simulated liquid exchange double body, which provides a closed gas structure to provide a release force. The maximum length of the intersection line between the side hall and the new bottom is formed without pushing the card around this word. beam

When the aerodynamic force is close to the supporting surface , the air is supported by the surface and begins to go crazy, the actual aerodynamic force increases, and the induced drag becomes a phenomenon of small aerodynamic force under the surface effect and the ratio of the lift generated when the surface effect is small. The air cavity occupied by the bottom of the ship under the cushioning state can keep the air inside and outside, and the high-speed jet that plays the role of a closed air cushion. When the air cushion craft is sailing at high speed, when the dynamic pressure of the air flow is increased, the air cushion pressure is increased, and the air curtain is deformed. The compressed air passes through the annular nozzle of the valve brake and continuously flows to the ship at a high speed, forming a near-jet air belt that plays a role, so that it produces air pressure.

The air is continuously and directly filled into the bell-shaped bottom of the book. Due to the influence of the original time change rate under the escape passage section, the flow pressure is balanced with the pressure difference between the inside and outside of the air chamber. When the air is closed, it will form a net pressure in the air chamber, so as to produce a cushion.
The positive air is passed through the inclined throat, which refers to the air shear of the air inside the steel pipe to close the air flow, thereby producing an air cushion.
The air flow around the arc formed by the aerodynamic force of the two jets at the inclined mouth is about the same as the outside world. If the influence of the air station and the jet width is ignored, the flow rate is equal to the jet width.
The pressure of the air given to the air cushion by the jet component is equal to the air flow. condizion

The surrounding jet flow is not based on the principle of the surrounding jet flow. Before it reaches the support surface, it will bend to the outside atmosphere and exit. The air volume in the air cushion will be greatly reduced, and the atmosphere will be opened. The deep flow base is greater than the shrinkage momentum of the air flow. The air flow that is emitted to the support surface is divided into two parts: the bending flow to the outside atmosphere and the air hall. The air flow of the air cushion is not a single flow. The air flow of the air cushion is based on the surrounding jet flow.

Definition and explanation
The air cushion generated by the air cushion is supported by the air cushion. The normal ship speed is zero. The air cushion is under the condition of cushion lift. The pressure and flow rate in the cushion lift system change in the curve. The pressure and flow rate change curve in the cushion lift system includes the cushion lift fan characteristic curve, the air pursuit curve. The combined characteristics of the airway before the wind are practiced, and the air grab characteristic curve. Under full lift, the sailing state of the ship is between lift and water level, without any out-of-order sailing state. In the absence of air cushion, the sailing state of the ship is supported by the buoyancy of water. Due to the action of the radial force, the ship's bow is tilted outward and the air cushion loses its shape, causing it to change from full pressure state to displacement state. The rate of air cushion instability. When the hovercraft is sailing at high altitude on the water, it is affected by aerodynamic forces such as air vortex force and hydrodynamic force, which generates a low force, causing the cylinder to collapse (or the front air to blow), which leads to a sudden deceleration and a large head return phenomenon, and the navigation shock when bowing and returning begins. The speed, wind speed and direction, deflection angle, etc. of the apron are too high. The lower edge of the coaming touches the water and is affected by the hydrodynamic pressure and the pressure change ratio, which causes the displacement of the edge toward the direction of the ship's expansion.

When the hovercraft is sailing at high altitude on the water, it is affected by aerodynamic forces such as air vortex force and hydrodynamic force, which generates a low force, causing the cylinder to collapse (or the front air to blow), which leads to a sudden deceleration and a large head return phenomenon, and the navigation shock when bowing and returning begins. The speed, wind speed and direction, deflection angle, etc. of the apron are too high. The lower edge of the coaming touches the water and is affected by the hydrodynamic pressure and the pressure change ratio, which causes the displacement of the edge toward the direction of the ship's expansion.
