The Effect of Rudder Speed upon Advance and Turning Lag with a Constant Steering Engine Power : With Reference to the Effect of Rudder Aspect Ratio

Abstract

A survey on the effect of rudder speed upon advance and turning lag with a constant steering engine power has been published in the report presented by Nihon Kainan Boshi Kyokai (N.K.B.K.) in 1966. The said report of N.K.B.K., howewer, has paid no consideration for rudder aspect ratio. This paper treats of this subject, taking account of rudder aspect ratio, which varies inevitably with changing the rudder speed with a constant steering engine power.
