Title of the invention Vertical control of vertical control of airship

`` Technical field J

The fundamentals of the airship's basic mechanism are fundamentally reformed, and the mechanism and operation control of the new airship.

"Background technology"

The conventional airship mechanism principle has the following defects. Airships currently in use do not have a vertical ascent / descent maneuvering function with static control.

Since the airship's envelope consists of a combination of a helium gas chamber for Junji and a front and rear paronet for adjusting the pressure of the envelope and adjusting the front and rear buoyancy, the helium gas chamber is raised due to the rise in atmospheric temperature. When inflated, the air in the front and rear parones is discharged and contracted, becoming stiff and increasing the buoyancy of the airship. When the helicopter gas chamber contracts due to a decrease in the atmospheric temperature, air is blown from the air blower to the front and rear paronets and expands and becomes heavy, reducing the buoyancy of the airship. As described above, the pressure of the envelope is kept constant by the pressure control function of the front and rear ports by the pressure control system, but on the other hand, the superheat due to the change of the atmospheric temperature. There are fatal flaws that cannot be addressed. In addition to the drawbacks of being unable to cope with changes in altitude due to ascending and descending air currents when being caught in turbulence during flight, landing is difficult if the airship is too light because there is no vertical cone landing function due to static adjustment. Because it is not possible to take off if it is too heavy, it is necessary to keep the difference in weight within a certain limit, so weight adjustment by ballast is an important inspection work for airships. As mentioned above, while the mechanism principle of airships is often flawed and the necessity of vertical lifting and lowering control by static buoyancy adjustment is recognized, it has long been considered that static adjustment is impossible in principle. Other mechanisms, such as the HealthTat® Tiller-ball-type airship, are being researched because of the shelving and the fundamental mechanism principle has not been reformed.

In order to overcome the shortcomings of the conventional airship mechanism, Static buoyancy by installing a lithium gas chamber (2) in addition to the lithium gas chamber (1) and the front and rear paronets (I1A, 1iB) to accumulate pressure and adding a compression / expansion ring device for a Helium gas The vertical ascent / descent control system with the adjustment function enables the airship to take off and land vertically, eliminating the need for inspection work for weight adjustment and super-heat.It can deal with altitude fluctuations due to ascending and descending airflow. -This clarifies the mechanism principle of the new type airship due to the fundamental mechanism principle reform.

"Disclosure of the invention"

The present invention will be described with reference to FIGS. 1 and 2. The static contact required for the vertical takeoff and landing of an airship is calculated by using the amount of real gas to the floating helium gas chamber (ガス) of the envelope (15). Then, from the negative state to the maximum positive buoyancy (pressure altitude), the floating helium gas chamber (1) to the solenoid valve (5A) and the solenoid valve (5 From A) to compressor (4), from compressor (4) to cooler (3), from cooler (3) to check valve (10A), from reverse it valve (1OA) A pipe (16) is connected to the accumulator helium gas chamber (2), and from this accumulator helium gas chamber (2) to the solenoid valve (5B), and from the solenoid valve (5B) to the temperature controller. To (6), from the temperature controller (6) to the check valve (i0B), from the iterator (10B) to the buoyant helium gas chamber (I), via pipe (16). The vertical lift with a vertical lifting motion effect is enhanced by the static buoyancy adjustment function that enables the expansion of the capacity of the helium gas chamber (1) by compressing and expanding by operating the connected helium gas compression and expansion circulation device. It is a vertical control device.

The buoyancy of the airship at the time of landing is a negative condition when the helium gas chamber (1) contracts to the minimum and the front and rear nets (11A, 1IB) expand to the maximum. The maneuvering operation releases the gas in the accumulator helium gas chamber (2) to the helium gas (1). The maximum buoyancy (pressure altitude) at which the air in the front and rear paronet (11A, 11Β) is exhausted by the expansion of the cell (1) and rises due to the increase in static force to take off vertically In this case, the floating gas chamber (ί) expands to the maximum and the front and rear paronets (11A, 11B) contract to the minimum. If the helium gas in the floating helium gas chamber (1) is compressed and sent to the accumulating helium gas chamber (2), the pressure control and system are activated as the helium gas chamber (1) contracts. Air is blown from the air blower (13) to the front and rear paronet (ίiA11B), and descends with a decrease in static buoyancy to enable vertical landing.

In addition, a solenoid valve (5A) for adjusting suction and a compressor (5A) for sucking and compressing the helium gas in the floating helium gas chamber (1), cooling it, and storing it in the accumulator helium gas chamber (2). 4) and the control circuit of the control unit (7) for controlling the cooler (3) are connected to the altitude designated sensor unit (8), and the accumulator helium gas chamber (2) is connected to the altitude designated sensor unit (8). Control of a control unit (9) that controls a solenoid valve (5B) and a temperature controller (6) for emission control for releasing and circulating helium gas to the helium gas chamber (1) It is an automatic altitude adjustment device in which the circuit is connected to an altitude designation sensor unit (8).

The vertical lift control device of the airship combines an automatic altitude adjustment device that automatically adjusts the buoyancy required at the specified altitude with the signal detected by the altitude designation sensor and the vertical lift control device.

When a stationary airship is trying to ascend under the influence of the atmosphere due to the effect of the atmosphere, a solenoid valve (δA) for intake and compression, a compressor (4) and a cooler ( 3) works, and the helium gas in the helium gas chamber (1) is stored in the helium gas chamber (2). The helium gas chamber (2) is pumped to the air blower (13) by the contraction of the helium gas chamber (2). Air is pumped to σ nets (1IΑ, 11 1), and the rise of the airship is prevented because the static buoyancy decreases with expansion of the front and rear paronets (11A, 11B). You. Conversely, when the airship is about to descend, a signal sensed by the altitude sensor (1B) and a solenoid valve (5B) for emission control and a temperature controller

(6) works, and the helium gas in the accumulator helium gas chamber (2) is released to the floating helium gas chamber (i), and the air valve is expanded by the expansion of the helium gas chamber (1). (12A, 12B) open and the front and rear paronets (11A, 1A)

The airship in 1 B) is discharged and the static buoyancy increases, preventing the airship from descending. In this way, the system of the automatic altitude adjusting device has an effect of maintaining a fixed altitude because the static altitude is adjusted to maintain the specified altitude.

"Best Mode for Carrying Out the Invention" and "Industrial Applicability" To explain the present invention in detail with reference to FIG. 1 and FIG. The best mode is an airship vertical ascent / descent control device that combines a vertical ascent / descent control device by operating a circulation device and an automatic altitude adjustment device. In addition, the cooler (3) and the temperature controller (6) were removed from the steam gas compression and expansion system S, and the control unit system of the automatic altitude adjustment device was also removed. The simplest simple vertical helium gas compression / expansion loop device eliminates the vertical lifting and lowering control device. Instead of the accumulator helium gas chamber (2), an accumulator tank can be installed outside the envelope (15) or on the gondola (Γ · 4). Further, the simple helium gas compression / expansion circulator is suitable for adjusting the buoyancy of a helium gas balloon.

The pressure difference between the internal pressure of the airship envelope (15) and atmospheric pressure is kept within a specified range, and the static buoyancy required for vertical landing of the airship is reduced from the negative state to the positive maximum buoyancy (pressure Control the static buoyancy required for vertical ascent and descent from negative to positive maximum buoyancy, and from positive maximum to negative buoyancy so that control can be performed within the range of altitude. The helium gas chamber (1), which has a large volume depending on the amount of helium gas, and a helium gas storage using a gas barrier material for the coating material and a fiber material having a high specific strength for the strength material Cover the entire pressure-resistant ball with a cover net for capture, suspend the upper part of the cover net with a cable, and connect the lower part of the cover net to the lower part of the envelope (15) (lower abdomen of the hull) with a cable. , Pressure accumulator helicopter due to the pressure difference ゥThe breakdown voltage sphere bag volume hardly changes by increasing or decreasing the amount of gas is obtained by partitioning using the accumulator helicopter Umugasu tuft (2). From the helium gas chamber (1) to the solenoid valve (5A), from the solenoid valve (5A) to the compressor (4), from the compressor (4) to the cooler (3), From the cooler (3) to the reverse Lh valve (1 OA), from the reverse it valve (10A) to the accumulator to the lithium gas chamber (2), each is connected by a pipe (〖6), and then connected to the accumulator. From the Umgas chamber (2) to the solenoid valve (5B), from this solenoid valve (-5B) to the temperature controller (6), from this temperature controller (6) to the check valve (10: B, The check valve (10B) is connected to the floating gas (1) by the solenoid valve (5A) of the vacuum gas expansion / compression device connected by a pipe (16). The control unit (7) of the compressor (4) and the cooler (3) is connected to the altitude designation sensor unit (8), and the solenoid valve ( 5 B) and temperature controller (6) control unit C9) to altitude specification sensor * Combination of automatic altitude adjustment device connected to unit (8) and vertical elevation operation device Vertical elevation operation control The details of the device Sakuina will be described in detail.

When an airship that is altitude set in the air is trying to ascend due to rising air temperature or ascending air currents, the signal detected by the altitude sensor sends a signal from the altitude sensor to the altitude sensor unit (8). The solenoid valve (5 mm), the compressor (4) and the control of the cooler (3) are sent to the control unit (7), and the solenoid valve (5 mm) and the compressor (4) are sent to the solenoid valve (5 mm). The operation of the cooler (3) and the operation of the cooler (3) cause the pumping of the helium gas in the floating gas chamber (1) to the accumulating helium gas chamber (2). Control system works, air is blown from the air blower (13) to the front and rear paronets (11A, 11Β) and expands and becomes heavier, raising the airship due to reduced airship buoyancy. Is prevented.

Also, when the airship is about to descend due to a decrease in atmospheric temperature or a downdraft, the signal sensed by the altitude sensor is output from the altitude designated sensor unit. (8) is sent to the control unit (9) of the solenoid valve (5B) and the temperature controller (6), and is operated by the operation of the solenoid valve (5B) and the temperature controller (6). Helium gas in the accumulating helium gas chamber (2) is released to the floating helium gas chamber (1), and the air valves (12A, 12B) are expanded with the expansion of the helium gas chamber (1). , The air in the front and rear paronets (11A, 11B) is discharged and shrinks, and the buoyancy of the airship increases, which prevents flying and the descent of the ship. In this way, the signal detected by the altitude sensor is transmitted from the altitude designation sensor unit (8) to the solenoid valve (5A) of the helium gas suction / compression section of the helium gas compression / expansion / circulation device and the compressor ( 4) Control of the cooler (3) * Control unit (7) and control of the solenoid valve (5B) and temperature controller (6) of the accumulator helium gas discharge section Automatic altitude adjustment to be sent to the unit (9). The system of the equipment is specified to adjust the static altitude so that the altitude of the airship is maintained at the specified altitude due to atmospheric changes. It has the effect of maintaining altitude.

The vertical takeoff and landing of the airship is performed by operating the vertical lift control system at will. At the time of landing, the airship is in a negative state without buoyancy, with the 撬 helium gas chamber (1) contracted to a minimum and the front and rear paronets (〖〖A, 11 1) expanded to a maximum. . During vertical take-off, the solenoid valve (5 mm) for release adjustment and the temperature controller (6) are activated by maneuvering operation, and the helium gas in the accumulator helium gas chamber (2) is transferred to the floating helium gas chamber (1). The air valves (12A, 12B) are opened by the expansion of the Chunpo Hembo Gas Chamber (I), and the air of the front and rear paronets (〖1A, 1iB) is discharged, and the airship Ascends by increasing static buoyancy. In addition, there is an effect that the levitation force increases due to a synergistic effect between the increase in the static buoyancy and the tilt structure thruster.

The maximum buoyancy (pressure altitude) of the airship is such that the floating gas chamber (1) expands to its maximum and the parones (11A, 11B) before and after are minimized. It is in the state of contraction. In a vertical landing, the solenoid valve (5 mm), compressor (4) and cooler (3) in the suction / compression section are operated by maneuvering operation, and the helium gas in the levitation helium gas chamber (1) is stored. The pressure is sent to the baffle (2), and the pressure-control system is activated by the contraction of the levitation air-gas baffle (1), and the air blower (13) receives the front and rear outlets (1).空気 Air is pumped to A, 11 B) and expands and becomes heavier, descends with a decrease in static buoyancy, and makes vertical landing. In addition, the descent speed increases due to the static buoyancy and the riding effect of the tilt structure propulsion. The illustration of the pressure control system, the tilt propulsion device, and the trim adjustment, which are not directly related to the present invention, are omitted. The airship in the text is a drinking airship, but it can also be used for rigid airships.

The airship of the present invention has a smaller absolute pay port than conventional airships, but does not require a ballast for hull weight adjustment and has a function to deal with the weight. There is a characteristic that the code shows. Tilt structure The dynamic buoyancy of the propulsion unit and the vertical buoyancy effect of the static buoyancy overcome the fatal flaws of conventional airships to enhance maneuvering stability with the vertical take-off and landing function. It clarifies the fundamental mechanistic reform of an airship that simplifies work and changes the way it operates.
