Near space balloon system safety release method

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...

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
