Abstract

In the case of KSLV-II flight test, the retro motor ignition is performed at the same time as the stage separation pyro-lock detonation, and the ignition energy of the retro motor is also supplied by an electrical drive signal from the PYDU(Pyrotechnic Driving Unit). Therefore, in order to verify final reliability prior to the KSLV-II flight test, a retro motor ignition test including a stage separation pyro-lock was performed at the dock of the Naro Space Center on August 11, 2021. The test results are summarized and described in this paper.

한국형발사체 비행시험의 경우 단분리시 단분리 파이로락 기폭과 동시에 역추진모터 점화도 함께 이루어지며 역추진모터 점화 또한 파이로구동장치에서 전기적 구동신호를 공급한다. 따라서 한국형발사체 비행시험에 앞서 최종 신뢰성 확보차원에서 2021년 8월 11일에 나로우주센터 선착장에서 단분리 파이로락을 포함한 역추진모터 점화시험을 수행하였으며 본 논문에서 그 결과를 정리하여 기술한다.
