Although scientific balloons have been used for space researches due to their flexibility and high cost efficiency, the duration of the flights are limited to a few days, since balloons loose their lift at night due to the shrink of the gas volume. It is well known that the super-pressure balloon, which keeps the positive pressure inside the balloon, can solve this problem, though this vehicle has not yet realized. The purpose of this research is to develop this super-pressure balloon based on the previous fundamental studies and also to develop a power supply system using fuel cells and a satellite communication system for the coming long duration flights.Through the three years of the study, we obtained following results.1. We developed the manufacturing technique of the super-pressure balloon including the connection method of the gores and the tendon ropes, the shielding method for the rope against the ultraviolet light, the treatment of the production error, the development of the apex and nadir fittings, the evaluation method using scaled models and the numerical simulations based on the spring and particle method, and the test method at the flight environment using a tandem balloon flight. We successfully demonstrated that a small super-pressure balloon with a volume of 2,000m^3 can withstand the super pressure with a safety factor of 10 in the flight environment.2. We developed a power supply system using fuel cells with a weight of 40 kg and the output power of 100 W without external humidifiers3. We studied the properties of the INMALSAT BGAN as a satellite communication system candidate

尽管科学的气球由于其灵活性和高成本效率而被用于太空研究，但由于气体的收缩，气球在晚上散发出电梯，因此飞行的持续时间限于几天。众所周知，尽管该车辆尚未意识到，但仍可以解决这个问题的超压气球可以解决这个问题。这项研究的目的是根据以前的基本研究来开发这种超压气球，并在未来长期长期飞行中使用燃料电池和卫星通信系统开发电源系统。通过研究的三年，我们获得了以下结果。1。我们开发了超压气球的制造技术，包括戈尔斯和肌腱绳的连接方法，针对紫外线的绳索的屏蔽方法，生产误差的处理，顶点和Nadir配件的开发，使用缩放模型的评估方法以及基于弹簧和粒子方法的数字模拟以及基于飞行的飞行方法，并使用了飞行方法。我们成功地证明了一个体积为2,000m^3的小型超压气球可以承受超级压力，而在飞行环境中，安全系数为10。2。我们使用重量为40千克的燃料电池开发了电源系统，而没有外部加湿器的输出功率为100 W3。我们研究了Inmalsat Bgan作为卫星通信系统候选人的特性
