内容記述 | The lobed-pumpkin shaped super-pressure balloon is able to withstand high pressure due to its small local curvature of the film being independent of the balloon size. It yields the small local curvature as a bulge among adjacent load ropes connected between the top and the bottom fittings. The small curvature is also expected if the balloon is covered by a diamond-shaped net with vertically elongated shape. In addition to the merit of the small curvature, the method using the daimond-shaped net has following merits; 1. the weight of the film is reduced since a weak but light film is able to be used by covering the balloon with a fine mesh net which mesh size is determined without depending on the gore width, 2. the deployment problem known for the lobed-pumpkin balloon can be solved due to its lack of additional films, 3. the capacity of resist pressure is not reduced due to the manufacturing error, since the local distortion of the mesh size does not affect the global balloon shape. We made a small balloon with a 3 m diameter using a 20 microm polyethylene film and a Kevlar net, and performed an inflation test which showed an expected burst pressure. We are going to make larger balloons for the ground inflation tests and launch a larger super-pressure balloon as a part of a tandem balloon system in 2011. | |||||
