초록

스피닝 공정은 축대칭의 얇은 두께를 가지고 있는 속이 빈 실린더형 단면을 가지고 있는 부품에 일반적으로 사용된다. 전통적인 스피닝 제작 기술은 컨벤셔널 스피닝과 파워 스피닝(전단 스피닝과 유동성형)으로 구분된다. 액체추진로켓의 연소기의 재생냉각 챔버와 확대노즐부에서 적용된 스피닝에 대한 문헌조사를 수행하였다. 연소실과 노즐의 제작에 사용되는 스피닝은 대부분 맨드럴을 사용하였다. 최근에는 전통적인 냉간 스피닝에 비해 열간 스피닝도 많이 사용되고 있었다.

Spinning process is generally used for manufacturing axisymmetrical, thin-walled thickness and hollow circular cross-section parts. Traditional spinning technology is classified to conventional spinning and power spinning(shear spinning and flow forming). Literature surveys of spinning application for regenerative cooling chamber and divergent nozzle of liquid propellent rocket thrust chamber have been conducted. Most spinning technology has been used mandel for manufacturing chamber and nozzle. Recently, hot spinning has been used much compared to traditional cold spinning.
