공압시스템의 공급능력 예측기법

Pneumatic system is widely applied to ground facility and launcher on-board system. One of the important aspects of pneumatic system is to meet pressure and flow rate requirements of gas consumers. In this paper, a systematic analytical approach for pneumatic system is proposed, which uses and systematically combines previous studies. The proposed analytical method is that pressure/flow calculation using conservation equations are combined with sonic limit check at vena contracta of the components of pneumatic system, which checks the installed components whether they are merely pressure loss elements or flow limiting element of the system. In this paper, gas consumers are categorized and simulated using the proposed method. The results reveal that the feeding performance of general pneumatic system can be properly estimated using the proposed approach.
