SIBULKIN根据流量连续和动量定律导得了皮托型进气道附加阻力的显函数分析式。但是,在给定的截取面积比时,实际使用却很困难。本文介绍一种附加阻力近似式,它用截取面积比及进气道前的静压系数与总压系数等几个较简单的项来定义。
SIBULKIN derived the explicit function analysis of the additional drag of the Pitot inlet based on the laws of flow continuity and momentum. However, practical use can be difficult at a given intercept area ratio. This paper presents an approximate formula for additional resistance, which is defined by a few simple items such as the cut-off area ratio and the static pressure coefficient and total pressure coefficient before the intake port.
