Description
Technical Field
The invention relates to the technical field of airships, in particular to a system for non-forming transfer and distribution of an airship on a stratosphere.
Background
As is known, the stratosphere is located at a height of 10km to 50km from the surface in medium-latitude regions, and starts at around 8 km from the surface in polar regions. The atmosphere of the stratosphere is stable in composition, the airflow flows horizontally, weather phenomena such as rain, snow, thunder, electricity and the like are basically avoided, the air density is only 1/14 which is equal to the air density of the ground, and the wind speed is generally 10-25 m/s. The stratosphere is the most calm section in the atmosphere, is hardly influenced by weather and is almost never wet due to the height interval and the unique climate condition, and meanwhile, the stratosphere has stable climate condition and good electromagnetic property. The optimal residence height of the stratospheric airship is 18-25km, and the sight distance coverage radius can reach about 500 km. Because the stratosphere is highly thin and the atmosphere is thin, in order to meet the requirement of large load capacity, the stratosphere airship needs to have enough buoyancy, so that the size of the airship is huge and is generally tens of thousands to tens of thousands of cubic meters. Such bulky airship is usually secured by a hangar of a corresponding size. When the flight task is executed, the airship needs to be moved to an external issuing field from the airship storehouse, issuing operation is carried out after the airship is confirmed to be normal, and the airship is lifted off. In order to reduce control in the rising process of the stratospheric airship and ensure that the airship can safely and stably reach the height of the stratosphere, some stratospheric airships are only filled with buoyancy lifting gas for lifting and staying empty in the ground airship body, and the airships are in an unformed state on the ground; after the airship is distributed, the buoyancy gas in the airship body gradually expands along with the increase of the height of the airship until the airship body is completely formed before the airship reaches the flat flying height.
However, the stratospheric airship which is not formed and distributed is large in ground wind resistance due to the fact that the airship body is not formed, and the unformed airship body cannot bear concentrated loads, so that certain difficulty is brought to transfer and distribution of the airship. Especially, after the airship is transported to the field from the cabin, the ground wind and the net buoyancy of the airship act together, so that the safety constraint of the airship becomes very difficult. When the airship arrives at the distribution area and distribution operation is carried out, airship restriction needs to be removed at the same time, the unshaped airship leaves the transfer platform to accelerate and rise, and the safety and reliability of the whole process are ensured. Therefore, it is a technical problem to be solved urgently to provide a safe and reliable non-forming distribution technology of stratospheric airship.

The length of the stratospheric airship is generally one hundred meters or two hundred meters, although the whole size is large, the total weight of the system is generally only several tons or more than ten tons, and the system is generally in a net light state due to the action of helium floatation force in the airship body.

The embodiment of the invention also provides a non-forming distribution method of the stratospheric airship, as shown in fig. 7, according to the time sequence, the distribution process can be divided into four stages, namely an airship preparation stage before delivery from the warehouse, an airship delivery stage, an airship adjustment stage before distribution and an airship distribution stage.
The method specifically comprises the following steps:
step S1, preparation stage before airship warehouse-out:
inflating an airship 1, restraining a position, which is on the airship 1 and is at a first height from the tail 10 of the airship, of the airship 1 by an active restraining device, restraining a position, which is on the airship 1 and is at a second height from the tail 10 of the airship, by a follow-up restraining device, restraining the tail 10 of the airship by a tail restraining device 8, so that the airship 1 is connected to a transfer platform 2, and adjusting the height, which is on the airship after being inflated and is at the transfer platform 2, to a preset first height by the active restraining device;
it can be understood that when the non-shaped distributed stratospheric airship is used on the ground, only buoyancy gas for lifting is available in the airship body, the whole airship is in a non-shaped state, and the inflated airship is the airship filled with the buoyancy gas for lifting.
The preparation stage before the airship leaves the warehouse is mainly to firmly connect the airship 1 and the transfer platform 2 so as to ensure the safety of the airship when the airship leaves the warehouse and is subjected to ground wind, and the operation is fast and effective when the airship is opened, restrained and released.
Step S2 airship warehouse-out and transferring stage:
moving the transfer platform 2 to transfer the airship 1 to a distribution area.
Step S3 adjusting stage before airship release:
the height of the airship 1 from the transfer platform 2 is adjusted to a preset second height through the active restraint device, and the inclination angle of the airship 1 relative to the vertical direction is adjusted to be within a preset range through the follow-up restraint device and the active restraint device;
step S4 airship issuing stage:
after the airship 1 enters the release window, the airship is released from the restraint of the active restraint device and the follow-up restraint device, and when the tail restraint device 8 is straightened, the tail restraint device 8 is cut off to be separated from the airship tail 10, so that the airship 1 is released.
As an example, in step S1, the adjusting the height of the inflated airship 1 from the transfer platform 2 to the preset first height by the active restraint device includes: the head pull rope of the active lifting mechanism 5 is released or furled by the active lifting mechanism 5 of the active restraining device, and the height of the airship from the transfer platform 2 is adjusted to a preset first height.
Based on the embodiment shown in fig. 2, a first active lifting mechanism 5-1, a second active lifting mechanism 5-2, a third active lifting mechanism 5-3, a fourth active lifting mechanism 5-4 and a back active lifting mechanism 5-5 are controlled simultaneously, a first head pull rope 4-1, a second head pull rope 4-2, a third head pull rope 4-3, a fourth head pull rope 4-4 and a back pull rope 4-5 are respectively drawn in or released, and the height of the airship 1 from the transfer platform 2 is adjusted to a preset first height.
It should be noted that, the restraining manner before the airship 1 leaves the garage is related to the size of the ground wind outside the hangar, that is, the corresponding first height under the ground wind speed outside different hangars is different, and the height of the airship from the transfer platform 2 is adjusted to the corresponding first height according to the different ground wind speeds, specifically including:
step S11, as shown in fig. 3, the airship 1 is set to be in the instability critical state when acted by the ground wind outside the hangar, the head pull ropes 4 in the downwind direction are in the critical loose state, the tension of the two head pull ropes 4 in the upwind direction are the same, the airship 1 does not rotate, and the formula (1) can be obtained
Wherein T is the pull force of the head pull rope, a is the included angle between the head pull rope 4 and the vertical line, CdThe aerodynamic drag coefficient of the airship head at the inflation section, V is the ground wind, V is the volume of the airship head at the inflation section of the airship 1, and FdThe pneumatic resistance of the airship 1 at the inflation section of the airship;
step S12, substituting corresponding parameters under different critical states into the formula (1) to respectively obtain a first speed, a second speed and a third speed;
step S13, if the ground wind speed is lower than the first speed, the head pull rope 4 is released, so that the pod 9 of the airship 1 can be transported in the air without falling on the transfer platform 2, thereby shortening the delivery time after reaching the delivery area.
If the ground wind speed is greater than or equal to the first speed and less than the second speed, the head pull rope 4 is furled, so that the pod 9 of the airship 1 falls on the transfer platform 2, and the waist pull rope 6 is tightened;
if the ground wind speed is greater than or equal to the second speed and less than a third speed, after the pod 9 of the airship 1 falls on the transfer platform 2, the head pull rope 4 is further drawn in to increase a, so that the horizontal component Tsina of the pulling force of the head pull rope 4 is greater than the received ground wind resistance Fd；
If the speed of the ground outside the airship warehouse is greater than or equal to the third speed, the airship 1 is transported and released at a greater risk, and the releasing operation is not implemented.
In the embodiment of the invention, the first speed is 2m/s, the second speed is 4m/s, and the third speed is 6 m/s.
As an example, in step S2, the transfer platform 2 may be started to carry the airship 1 and slowly move from the airship storehouse to the distribution area, and if the airship 1 is influenced by the ground wind during the transfer and the departure of the airship 1 from the airship storehouse, and the hull deflects downward wind direction beyond the preset deflection range, the upwind head pull rope 4 and the waist pull rope 6 are tightened to make the hull deflection within the preset deflection range to resist the ground wind resistance that may be encountered, so as to ensure that the airship 1 is normally transferred.
As an example, the step S3 includes: and the active lifting mechanism 5 of the active restraint device releases the head pull rope 4, the height of the airship 1 from the transfer platform 2 is adjusted to a preset second height, and in the process, the follow-up lifting mechanism 7 of the follow-up restraint device controls the waist pull rope 6 in a follow-up manner, so that the waist pull rope 6 is in a tightening state, and the inclination angle of the airship relative to the vertical direction is controlled within a preset range. The airship 1 is lifted up by performing adjustment before release in step S3, the release speed of the airship 1 can be increased, and the release process can be shortened.
Based on the example shown in fig. 2, step S3 may specifically include: controlling a first active lifting mechanism 5-1, a second active lifting mechanism 5-2, a third active lifting mechanism 5-3, a fourth active lifting mechanism 5-4 and a back active lifting mechanism 5-5, and releasing a first head pull rope 4-1, a second head pull rope 4-2, a third head pull rope 4-3, a fourth head pull rope 4-4 and a back pull rope 4-5 at the same time to enable the height of the airship 1 to rise to a second preset height; meanwhile, the first follow-up lifting mechanism 7-1, the second follow-up lifting mechanism 7-2, the third follow-up lifting mechanism 7-3 and the fourth follow-up lifting mechanism 7-4 are controlled in a follow-up mode, so that the first waist pull rope 6-1, the second waist pull rope 6-2, the third waist pull rope 6-3 and the fourth waist pull rope 6-4 are in a tightened state in the lifting process of the airship. This process continues until the airship tail 10 leaves the transfer platform 2, placing the tail guy rope 8-1 of the tail restraint 8 in tension.
As an example, the step S4 includes:
in step S41, after the airship 1 enters the release window, the restriction of the waist pull rope 6 is released, as shown in fig. 4, and then the restriction of the head pull rope 4 is released, as shown in fig. 5.
Still based on the example shown in fig. 2, wherein if the ground wind is greater than the first speed, the down-wind waist cord 6 restraint is released, then the up-wind waist cord 6 restraint is released, then the down-wind head cord 4 restraint is released, and then the up-wind head cord 4 restraint is released;
if the ground wind is opposite to the advancing direction of the transfer platform 2, after the restraint of the waist pull rope 6 is released, the head pull rope 4 at the front part of the airship with the advancing direction as the reference is released, and then the head pull rope 4 at the rear part of the airship is released, namely, the restraint of the third head pull rope 4-3, the fourth head pull rope 4-4 and the back pull rope 4-5 is released, and then the restraint of the first head pull rope 4-1 and the restraint of the second head pull rope 4-2 are released.
If the ground wind is consistent with the advancing direction of the transfer platform 2, after the restriction of the waist pull rope 6 is released, the head pull rope 4 at the rear part of the airship with the advancing direction as the reference is released, then the head pull rope 4 at the front part of the airship is released, namely, the restriction of the first head pull rope 4-1 and the second head pull rope 4-2 is released, and then the restriction of the third head pull rope 4-3, the fourth head pull rope 4-4 and the back pull rope 4-5 is released.
Step S42, after the head pull rope 4 is released, the slowly descending portion 3 connected to the head pull rope 4 moves in a direction away from the airship and slowly descends, the airship 1 ascends at an accelerated speed, the airship tail 10 leaves the transfer platform 2, the tail pull rope 8-1 of the tail restraint device 8 is straightened, the tail pull rope 8-1 is cut off by the cutting device, the tail pull rope 8-1 is separated from the airship tail 10, and the airship 1 leaves the transfer platform 2 to complete distribution, as shown in fig. 6.
As an example, the step S42 includes: the cutting device cuts off the tail pull rope at the joint of the tail pull rope and the tail of the airship, so that the tail pull rope 8-1 left on the airship 1 is as short as possible, and the distribution speed of the airship 1 is increased.
Specifically, the first head stay 4-1, the second head stay 4-2, the third head stay 4-3, the fourth head stay 4-4 and the back stay 4-5 are constrained to respectively carry the first slowly descending part 3-1, the second slowly descending part 3-2, the third slowly descending part 3-3, the fourth slowly descending part 3-4 and the back slowly descending part 3-5 to move in the direction away from the airship 1 and slowly descend. The airship 1 will rise with higher speed, the airship tail 10 will also leave the transfer platform 2, and the tail pull rope 8-1 is gradually straightened, so that the tail pull rope 8-1 is separated from the airship tail 10 by the cutting device after the airship tail 10 has enough safety height. At this point, all the constraints of the airship 1 are released, the airship 1 leaves the transfer platform 2, namely the distribution is completed, and the ascending stage is entered.
The system provided by the embodiment of the invention has the advantages of simple structure and low cost, and can ensure the safety and reliability of each stage of preparation before the airship leaves the warehouse, transportation before the airship leaves the warehouse, preparation before the airship is issued and the airship is issued, thereby improving the safety and reliability of the unshaped issuing of the airship on the stratosphere.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
