Abstract

KSLV-I (Korea Space Launch Vehicle-I) upper stage KM (Kick Motor) is a solid propulsion system which consists of igniter, SAD (Safety Arming Device), composite case, and submerged nozzle capable of TVC (Thrust Vector Control) actuation. Each subsystem of KM fulfilled development requirements for achieving a flight mission successfully. We confirmed the successful development of KM from the $3^{rd}$ flight test results of NARO on January 30, 2013. This article deals with the requirements of KM and the results on configuration management, mass variation, thrust axis alignment, and major test results and so on.

KSLV-I (Korea Space Launch Vehicle-I) 상단 킥모터는 고체 추진기관으로 점화기와 점화안전장치로 구성된 점화구동부, 복합재 케이스부, 추력벡터제어가 가능한 잠입형 노즐부, 그리고 추진제로 구성되어 있다. 킥모터를 구성하는 각 서브시스템들은 비행 임무 달성을 위한 개발 요구조건을 만족시켰으며, 2013년 1월 30일 나로호 3차 비행 시험 결과로부터 성공적으로 개발이 완료되었음을 확인할 수 있었다. 본 논문에서는 킥모터에 대한 요구조건, 요구조건을 만족하기 위한 형상관리, 중량 변화, 추력 축 정렬 결과 및 주요 시험 결과 등에 대해 다루었다.
