Description
Technical Field
The utility model relates to an airship technical field especially relates to a pull airship and stratosphere airship.
Background
The stratospheric airship has very wide military and civil values, and has great application values in the aspects of communication, remote sensing, space observation, atmospheric measurement and the like. An airship, one type of aerostat, is an aircraft that uses a lighter-than-air gas to provide lift. The lift obtained by the airship mainly comes from lighter-than-air gas filled inside the airship, such as hydrogen, helium and the like.
Because the stratospheric airship which is being developed needs to be conformal in the descending process, the stratospheric airship can be conformally descended only after the weight of the stratospheric airship is increased by inputting air into the airship to form gravity which is larger than buoyancy. During the descent process of the stratospheric airship, the stratospheric airship can be blown away by a strong wind and deviate to a far area from a preset descent point when passing through a turbulent layer. The air blower for inputting air needs to consume a large amount of energy, and the energy is remained when the stratospheric airship descends to be close to the ground. The remaining energy of the system (including the capacity of the solar cell and the energy storage battery) is not enough to provide the stratospheric airship with low-altitude return field. In addition, because stratospheric airships are bulky, transport to the hangar from areas that are far from the intended drop point is difficult.
In the prior art, an initiating explosive device is used for blasting and tearing an outer capsule of an airship on a stratosphere, and the airship is broken and falls after helium is released, so that the airship returns to the field in a preset area. However, after the stratospheric airship made of heavy metal falls from high altitude, impact force is generated to seriously damage equipment, battery packs, bag body materials and the like on the airship, so that the airship cannot be reused, and great waste is caused.
Therefore, it is desirable to provide a towed airship and a stratospheric airship that can ensure safe and complete return of the stratospheric airship.

According to the utility model discloses a first embodiment, the utility model provides a pull airship 1, as shown in fig. 1 and fig. 2, the airship that fig. 1 is located the upper left side is for pulling airship 1, pulls airship 1 and includes: the airship comprises an air bag 14, a nacelle 113, a towing rope winch 111, a towing rope 110, a collar 18, an elastic damper 19, a towing airship heading vector propulsion system 11, a towing airship nose cone 12, a towing airship local reinforcing frame 15, a plurality of towing airship pitch vector lateral thrust systems 13, a plurality of nacelle towing lateral thrust systems 112, a first observer 16, a towing airship tail wing rudder 17, a plurality of bowknots 114, a plurality of tying ropes 115, a towing airship tail cone 116 and a reinforcing frame 117.
The balloon 14 is an approximately ellipsoidal body.
The gondola 113 is fixed under the middle of the airbag 14. On either side of the pod 113, a plurality of pod towing side thrusting systems 112 are provided for generating power for flying the towed airship 1 forward. In the scheme, two pod dragging side-pushing systems 112 are symmetrically arranged at two sides of a pod 113, and as the dragging airship 1 needs to provide power to fly, the dragging airship 2 needs to drag a stratospheric airship, and in order to increase the power, a plurality of groups of pod dragging side-pushing systems 112 can be arranged.
The towing airship tail cone 116 is fixed to the tail (rear) of the air bag 14 of the towing airship 1 and is located on the central axis of the air bag 14. As shown in fig. 1, since the stratospheric airship 2 is towed by the tail cone 116, the point of force is aft rather than at the pod, requiring the addition of a reinforcing frame 117 between the aft and the pod, cradle and aft point of force at which the engine is mounted.
The tow rope winch 111 is located at the rear of the tow airship tail cone 116. As shown in fig. 13, the tow rope winch 111 and tow airship tail cone 116 are connected by a truss structure. The tow rope 110 is wound around a tow rope winch 111, and a collar 18 is provided at the tail, i.e., the distal end, of the tow rope 110, and an elastic damper 19 is provided between the tow rope 110 and the collar 18. The collar 18 is preferably self-locking, with automatic opening and closing being achieved by the collar motor 18-3. As shown in fig. 3 and 4, the collar 18 includes: an outer ring housing 18-2, an inner ring rack 18-1, a collar gear 18-4 and a collar motor 18-3. An inner ring rack 18-1 and a collar gear 18-4 are provided within the outer ring housing 18-2, the inner ring rack 18-1 and the collar gear 18-4 being in mesh. The lantern ring motor 18-3 drives the lantern ring gear 18-4 to rotate, and further drives the inner ring rack 18-1 to rotate. The outer ring housing 18-2 is of an arcuate configuration. Both ends of the outer ring housing 18-2 are provided with collar openings. The inner ring rack 18-1 is of an arc-shaped structure.

When the inner ring rack 18-1 extends out of the outer ring shell 18-2 from one collar opening and extends into the outer ring shell 18-2 from the other collar opening, the inner ring rack 18-1 and the outer ring shell 18-2 form a complete ring structure, and the collar 18 is in a closed ring state. When the lantern ring 18 is changed from the closed ring state to the open ring state, only the inner ring rack 18-1 needs to rotate into the outer ring shell 18-2, so that the structure formed by the outer ring shell 18-2 and the inner ring rack 18-1 is an arc-shaped structure.

In the inner container 19-9, one side of the piston 19-5 close to the pull rod channel is provided with hydraulic oil, and the other side is provided with air.
The working principle of the elastic damper 19 is as follows:
when the elastic damper 19 is under tension: the pull rod 19-1 pulls the piston 19-5 to gradually approach a pull rod channel, the piston 19-5 compresses the first pressure spring 19-3, the sliding of the piston 19-5 compresses hydraulic oil, so that the hydraulic oil enters the outer container 19-11 through the second one-way damping oil valve 19-4, the hydraulic oil entering the outer container 19-11 extrudes the oil ring piston 19-10, the oil ring piston 19-10 compresses the second pressure spring 19-6, and the air is sucked into the air inlet and outlet 19-7 of the inner container.
When the elastic damper 19 is not under tension: the first pressure spring 193 releases pressure, the piston 195 gradually gets away from the pull rod channel, the second pressure spring 19-6 releases pressure, the oil ring piston 19-10 is pushed to approach the pull rod channel, hydraulic oil enters the inner container 19-9 from the outer container 19-11 through the first one-way damping valve 19-2, and air in the inner container 19-9 is exhausted through the inner container air inlet and outlet 19-7.
