초록

고고도 과학기구는 다양한 과학연구목표를 수행하기 위해 미국, 프랑스, 일본과 같은 항공우주선진국에서 수십 년간 사용되어 왔다. 고고도 과학기구는 초기 개발 및 운용비용이 막대하게 소요되므로 국가연구기관 중심으로 연구개발이 진행되어 왔지만 최근에는 저비용 고성능 오픈소스 소프트/하드웨어 생태계의 출현으로 과학기구 개발 진입장벽이 낮아졌다. 본 연구에서는 상용 기성품을 활용하여 저비용, 사용 용이성, 호환성, 제품 개발신속성을 고려한 소형 영압력기구(Zero Pressure Balloon) 시제품을 제작하였다. 또한, 8회에 걸친 비행시험을 통하여 비행운용기술을 축적하였으며 기구시스템의 작동신뢰성을 검증하여 향후 대형 영압력기구 운용을 위한 기반을 구축하였다.

The high altitude scientific balloon has been used for decades in advanced aerospace countries such as United States, France, and Japan to carry out various research objectives. Since the initial cost for development and operation is enormous, it has been conducted by national research institutes. Recently, the advent of open source software/hardware ecosystems with low-cost yet high-performance have lowered barriers to enter into scientific balloon research and development. In this study, a zero pressure balloon prototype was designed considering the cost, usability, compatibility, and development period by using commercial off the shelf (COTS) items. In addition, the flight operation experience was accumulated through eight times of the flight tests, and operational reliability of the balloon system was verified. Finally, the foundation for the operation of the large zero pressure balloon was established.
