Description

A near-space balloon system and its transportation device

technical field

The utility model belongs to the technical field of near-space aircraft, in particular to a near-space balloon system and a transportation device thereof.

Background technique

The near-space balloon is a kind of aircraft that can perform flight missions in the space area 20-100 km above the sea level for a long time. It mainly includes two types of super-pressure balloons and zero-pressure balloons. High, low cost, long stay in the air and other advantages. Using near-space balloons to carry corresponding workloads can achieve application purposes such as meteorological environment monitoring, regional communications, national land census, urban traffic monitoring, earth exploration, space observation, and high-altitude adventure tourism.

Usually near-space balloons mainly include four parts: airbag, valve assembly, parachute and working load. Among them, the airbag is made of ultra-thin flexible composite material, which has the characteristics of large volume and good airtightness. It is used to fill the buoyant gas to make the balloon system To obtain enough lift to lift off, the valve assembly is composed of deflation valve, safety control device, sensor and emergency power supply. The parachute is centrally connected to the working load and the airbag, and is mainly used for the safe landing and recovery of the working load.

After completing the manufacturing and testing of each component of the balloon, the components of the balloon are reliably stored and transported, and in the process of preparations such as integration and debugging before the release of the balloon, the system integration is quickly completed and the components of the system are avoided. Damage is the key to ensuring the successful launch and long-term stay of near-space balloons.

At present, the storage and transportation of near-space balloons at home and abroad are realized by independent packaging of each part, separate storage, and centralized transportation to the test site. The disadvantages of this storage method are:

1) The system requires more packing boxes, takes up a lot of storage and transportation space, and may easily cause loss and damage of components and materials during storage and transportation.

2) Long-term storage of airbag materials in an open and bright environment will cause a large decline in performance, and non-airtight storage conditions are not conducive to long-term storage of airbags.

3) Before the system is released, the structure and electrical integration assembly needs to be temporarily carried out at the test site, which takes a long time, and the airbag and other components are easily damaged during the assembly process.

It is an effective way to solve the rapid deployment of near-space balloons by first installing and integrating all parts of the manufactured near-space balloons, and then storing or transporting them. However, there are many safety problems in the simple way of first assembling and then packing boxes for storage and transportation, which makes it difficult to be adopted in engineering practice:

1) The area and size of the airbag material of the adjacent space balloon is large, and the disorderly folding method is adopted. The airbag is easily deformed and scattered during the storage and transportation process. The work is easy to cause damage to the airbag.

2) The connection between the valve assembly and the airbag is a combination of rigid and flexible structures. If the two are placed in the same storage and transportation space, there is no proper restraint method. Collision and interference during storage and transportation will cause damage to the structure of the two, or other The butt joint loses its sealing performance.

3) The state of the folded parachute is required to remain stable. Interference and extrusion during storage and transportation may lead to confusion and entanglement of the parachute, which may cause the parachute to fail to open normally during subsequent flights.

4) The working load is generally precision instruments and equipment, which requires a shock-absorbing, well-sealed storage and transportation environment to avoid impact and extrusion by other structures.

In short, the existing technology is difficult to maintain the continuity and stability of the storage and transportation of near-space balloon assemblies, and is not suitable for long-term storage and long-distance transportation, nor is it suitable for the application requirements of rapid deployment of near-space balloon systems.

Therefore, it is necessary to provide a technical means to solve the above shortcomings.
