Abstract

Results of a numerical simulation of a flowing of the underwater vehicles hull with the pump-jet nozzle are presented. It was calculate velocity distributions coefficients of the lift force the longitudinal moment of the hull with the pump-jet nozzle and isolated hull for some values of angle of attack. It was shown that the area of the influence of the nozzle on the velocities distribution of the hull and character of changing of coefficients of the lift force and the longitudinal moment and their derivatives depending on angle of attack.

본 논문에서는 펌프 노즐이 부착된 잠수 선형의 유동에 관해 수치해석 결과를 보여준다. 이는 속도분포, 양력계수, 영각의 값을 갖는 펌프젯 노즐이 선체와 부착되었을 때와 부착되지 않았을 때의 종강도 모멘트 등의 값들을 계산한다. 선형의 속도 분포에 따른 노즐의 영향면적과 양력계수(변호의 특성요인) 종강도 모멘트, 영각에 따른 도함수 등을 보여준다.
