파이로테크닉 분리 너트의 설계 개념 연구

Research for design concept of pyrotechnic separation nut has been carried out prior to design a pyrotechnic separation nut with resettability and reduced pyroshock which may cause damage to surrounding structures. As a reference, previously proposed separation nut design has been investigated and based on the investigation, possible design parameters are determined. Equations of motion for combustion gas and components is derived and analysis framework has been established with those.
