Problems solved by technology

[0007] (3) In this distributing method, the separation of the balloon and the releaser is to adopt the mode of pulling the rope on the ground to control the disengagement of the releaser. Because the height of the balloon is high before it lifts off, it is in an unstable state in the air, and the rope is a flexible structure. It is difficult to transmit the pulling force to the releaser control mechanism in a timely and accurate manner, which makes it difficult to achieve safe and reliable separation of the releaser and the balloon;
[0008] (4) With this release method, during the process of the balloon lifting off the ground, it is necessary to accurately control the status of the balloon (ascending speed, direction of the balloon, etc.), so it is required to have a long period of stable weather conditions, a relatively wide and flat ground, and several skilled personnel. Accurate coordination of operators can avoid balloon or pod damage accidents; in addition, limited by the small mass of motor vehicles equipped with winches, this method is only suitable for no wind or light wind conditions with a total buoyancy of no more than 1 ton Issuance of the balloon system

Embodiment 1

[0055] see Figure 1 to Figure 3 , the near-space balloon system is mainly composed of a balloon 1, a pod 10 and a rope 2 for connecting the balloon 1 and the pod 10, and four descenders 9 are arranged on the top of the pod 10; The mooring rope 4 on the winch 8, the rope cutter 5 installed on the mooring rope 4, and the cable 6 for powering the rope cutter 5 constitute.

[0056] The balloon 1 of the near-space balloon system has a volume of about 20,000 cubic meters, and the weight of the pod 9 is 400kg. After the ground is filled with a specified volume of helium, the net buoyancy is about 150kg, and the length of the rope in the descent device 9 is 35m. The distribution method and steps of the balloon system are as follows:

[0057] (1) The pod 10 is arranged on the central position of the four hoists 8 in the distribution area of ​​the testing ground, and the four slow descenders 9 are fixed on the top of the pod 10;

[0058] (2) Partially take out the balloon 1 from the ...

Embodiment 2

[0068] see Figure 5 to Figure 6 , in order to safely recover the pod, the near-space balloon system in this embodiment is mainly composed of a balloon 1, a pod 10, and a rope 2 for connecting the balloon 1 and the pod 10, which is different from the composition of the balloon system in Embodiment 1 The feature is that a descender 9 is installed at the center of the top of the nacelle 10, and a set of parachutes 13 is also arranged between the bundled end below the rope 2 and the descender 9.

[0069] Since the described descender 9 does not need to consider the expansion effect of the balloon 1 after it is lifted into the air, the length of the rope inside it is set within 3m-10m.

[0070] The dispensing process of the balloon system is basically the same as that of the balloon system in Embodiment 1, except that a parachute 13 needs to be installed between the cluster end below the balloon system rope 2 and the descending device 9 in the deployment phase; the balloon 1 Afte...

Abstract

The invention discloses a near space balloon system safety release method. The method comprises an unfolding stage, an inflation stage and a let-fly stage. By adopting the method, the windward area of a balloon is small in the inflation stage, an obvious wind-catching phenomenon is not caused, a set of hoists is adopted for multi-point constraint, the state of the balloon is controlled, thus the balloon is fixed safely and reliably, the wind resistance ability is high, thus the whole release process of a balloon system can be completely carried out in an external field, and a shelter place or a large-area ground is not needed; a descent control device is adopted, so that the liftoff speed of a nacelle and the relative speed between the nacelle and the balloon are lowered and the balloon system is lifted off safely; in the release process of the balloon, release can be performed only under the condition that rope belts are at a straightened state between the balloon and the nacelle, the balloon can be released without waiting for completely lifting off the ground, one person can complete initiation of all rope cutters in release operation, the operation is quick, and the response is timely and reliable; the release process is safe and smooth, and the method can be surely applied to releasing large-scale near space balloon systems with the load being higher than 100 kg.

Description

technical field [0001] The invention relates to a method for safely releasing a near-space balloon system. Background technique [0002] The near-space balloon system is an aircraft that can work in the near space (space area 19-100 km above sea level) for a long time. Compared with other aircraft, it has the advantages of high flight altitude, low cost, long time in the air, and short preparation period. , easy and flexible implementation and other unique advantages. In the construction of the national economy, the use of near-space balloon systems to carry corresponding workloads can complete meteorological environment monitoring, regional communications, national land surveys, urban traffic monitoring, earth exploration, urban security and high-altitude adventure tourism. In the military field, the near-space balloon system can be used as a regional navigation and positioning platform, a continuous high-resolution earth observation and surveillance platform, a missile ear...
