Definitions
- the invention relates to a side wall air cushion vehicle according to the preamble of patent claim 1.
- a guer-running separating device is also provided between the front and rear aprons, which divides the hovercraft space into two compartments. At least one blower maintains the air cushion in each compartment. An air discharge flap or the like is also provided for reducing the air cushion pressure.
- the separator which is usually designed as an apron, maintains a pressure difference between the compartments. It can be designed so that it is soft and flexible at approximately the same pressure in the compartments, but becomes relatively stiff at a pressure difference. With the aid of such a separating device, there is the possibility of influencing the ramming movements of the ship in the sea by pressure differences in the compartments.
- the invention has for its object to design a side wall hovercraft in such a way that the sea behavior, in particular the tamping behavior, is improved without large air losses.
- a passage device which is adjustable by an actuating device and controllable by the control or regulating device is provided for the separating device, the passage cross section of which depends on the ramming angle, the ramming angular velocity and / or the pressure in the compartments is adjusted. If there are different pressures in the compartments due to the swell, this is an indication of, for example, a pounding movement of the ship. With a suitable pressure situation in the compartments, the ramming movement can be counteracted, as is known per se.
- the invention provides a passage device for the separating device which, depending on the tamping behavior of the ship and / or the pressure difference, accomplishes a more or less large pressure compensation. It is no longer necessary to open an air discharge flap for a pressure build-up in order to build up a pressure again in the next moment with the aid of a blower, which compensates for the tamping movement on the next wave.
- the passage device ensures a distribution of the pressure in the departments in such a way that the desired pressure difference is present in each case, without air losses having to be accepted. It is conceivable to set the passage device to a fixed value.
- the invention provides for the passage cross-section through the passage device to be changed as a function of the swell, ie the measured ramming angle or the ramming angular velocity.
- the passage device has an adjustable flap which is arranged in a channel in the fixed structure above or in the separating device.
- the flap can be adjusted by a suitable actuating device in order to bring the flow cross-section to the desired value. If the channel is in the separator itself, it will preferably provided directly below the solid structure. At this point it is naturally easiest to accommodate a flap and to control it from the fixed structure using an actuator.
- a passage device has at least two inflatable sections, the internal pressure of which determines the flow cross-section between the inflatable sections. It is conceivable to arrange or design the inflatable sections such that the flow cross-section changes automatically at different differential pressures.
- the separating device can have an inflatable separating apron, the internal pressure of which corresponds to the degree of sealing between the compartments. If the internal pressure is low, there is more pressure equalization between the compartments than if the internal pressure is higher. If the internal pressure is therefore made dependent on the measured parameters, such as ramming angle, ramming angular velocity or pressure in the compartments, it can also determine the influence of the compensating flow between the compartments and thus optimize the sea state behavior, in particular the ramming behavior.
- Fig. 1 shows schematically a side wall hovercraft with a device according to the invention.
- Fig. 2 shows another embodiment of the side wall .. hovercraft according to the invention.
- Fig. 3 shows a third embodiment of a side wall hovercraft according to the invention.
- FIG. 4 schematically shows a middle separating apron of the side wall hovercraft according to the invention with a schematically indicated passage device.
- FIG. 5 shows a side view of the separating apron according to FIG. 4 in the direction of arrow 5.
- FIG. 6 shows a section through a middle separating apron of the side wall hovercraft according to the invention with a modified passage device.
- FIG. 7 shows a third embodiment of a passage device for the separating apron of a side wall hovercraft according to the invention.
- a side wall hovercraft 10 according to FIG. 1 has two parallel fuselages, one of which can be seen at 12, which are connected to one another by a fixed structure 14. Between the hulls a front apron 16 extends in the front area and a rear apron 18 in the rear area, each of which can be inflated by blowers 20, 22 for the purpose of sealing the space between the aprons 16, 18. This is divided approximately in the middle by a middle separating apron 24, which therefore forms a front compartment 26 and a rear compartment 28. The separation apron 24 is also through a blower 30 inflated.
- the compartments 26, 28 are assigned a fan 32, 34 with which the compartments 26, 28 can be placed under a predetermined pressure to form air cushions which raise the vehicle 10 in the water.
- a channel 36 is formed below the fixed structure 14 in the region of the separating apron 24, in which a pivotable flap 38 is arranged.
- the flap 38 can be adjusted by an actuator 40 which is controlled by a processor 42. This arrangement is shown enlarged in FIG. 6.
- the compartments 26, 28 are assigned pressure sensors 44, 46 which are connected to the processor 42.
- a gyro 48 and a front motion sensor 50 and a rear motion sensor 52 are also connected to the processor.
- the sensors 50, 52 measure e.g. the pitch angle, and with the help of the gyro 48 the position of the vehicle 10 can also be determined. If the ship 10 is stomping in the water, there are pressure differences between the compartments 26, 28 which, under certain circumstances, still adversely affect the tamping.
- a pressure equalization between the compartments 26, 28 takes place in a metered manner via the channel 36, the cross-sectional limitation in the channel 36 being determined by the position of the flap 38.
- the position occurs as a function of the measured values for the ramming angle or the ramming angle speed, which can be calculated in the processor 42 from the angle values. Furthermore, in addition or independently of this, the setting of the flap 38 can be made dependent on the values determined by the pressure sensors 44, 46.
- the side wall hovercraft of FIG. 2 differs from that according to FIG. 1 in that a single blower 60 supplies the compartments 26, 28 with compressed air via two channels 62, 64, the distribution of the compressed air to the compartments 26, 28 being determined by the position of a flap 66, which is also actuated by the actuator 40.
- the tamping behavior is influenced by pressure equalization between the compartments 26, 28 in the same way as described for FIG. 1.
- each of the channel sections 62, 64 there is a throttle valve 68, 70 which can be actuated by actuators 72, 74.
- the actuators are also controlled by the processor 42, which is also connected to actuators 76, 78 for actuating flaps 80, 82 in outlet shafts 84, 86 for venting the compartments 26, 28.
- the compartments 26, 28 can therefore be assisted of the fan 60 and the vents 84, 86 are specifically ventilated and vented, wherein pressure equalization can also take place via the channel 36 in the separating apron 24.
- the control of these parts by the processor 42 takes place in such a way that an optimal movement behavior of the ship 10 is achieved in adaptation to the respective water movement.
- a middle separating apron 90 is shown, which has a channel 92 below the fixed structure 14, which can be closed with the aid of two flexible hoses 94, 96.
- the pressure within the hoses 94, 96 determines the passage cross section, as can be seen from the dashed and solid lines in FIG. 5, for example.
- the air pressure is controlled in a similar manner as the flap 36 when the 1 to 3 for determining the desired flow cross-section for the pressure equalization to be achieved between the compartments 26, 28th
- a separating apron 100 which has a meandering shape, for example. It is continuous up to the fixed structure 14 and can be bridged by a channel 102 in the fixed structure 14.
- a flap 104 is arranged in the channel 102 and can be actuated in a manner similar to the flap 38 in the embodiments according to FIGS. 1 to 3 and 6.
