screw압축기는 진동이 적고, 소형이면도 그효율 유지가 용이하다는 특징을 가지고있으며, 왕복압축기와 같은 crank가 없고 원통형 밀폐용기 내에 암,수 로타가 서로 반대 방향으로 맞물려 회전하면서 로타홈과 케이싱 사이에 생기는 공간의 용적이 로타의 회전에 의해서 가스를 연속적으로 흡입, 압축, 배출하는 용적형압축기이다. 본 연구는 screw 압축기의 성능에 큰 영향을 미치는 로타의 치형함수의 기하학적성질 및 제한사항을 서술하였고, 로타의 형상이 특성값에 미치는 영향을 이론적으로 해석 하기 위하여, 임의의 치형을 갖는 로타를 만들고, 이것과 맞물리는 상대로타의 치형을 설계하여 seal line length와 blow hole area을 계산하였다.

This study aims at the optimal design of the screw rotor, its performance analysis, and development of a small screw supercharger which has a low noise compared with the root type supercharger. The basic theoretical equations and the basic design of the screw supercharger have been established. The optical design of the screw rotor's shape has been also performed theoretically. Also, the performance analysis technique of the designed screw rotor has been developed.

This study aims at the optimal design of rotors and the development of screw type Supercharger of CNG-fueled engine for commercial vehicle. Based on the new rotor profile, an advanced oil free type Supercharger has been developed, which can achieve higher adiabatic efficiency and lower manufacturing cost. The performance test of screw type Supercharger has achieved high volumetric efficiency and the durability on the bench of performance test has also been established in the compact body.
