In this paper, a nounal test with table L9(34) has been ed for a new type of flap rudders, and put forward some regression formulae of hydrodynamic performance,such as rudder normal force derivahve fa, the critical angle of attack ah and rudder nounal force coefficient CN, these formulae had been validated by the flap rudder in 9000t cement - carrier ship.
本文通过对新型襟翼舵舵模的L9（34）正交试验研究，给出一套包括襟翼舵法向力导数fα、临界攻角α(kp)和法向力系数CN的回归公式，并经9000吨自卸式水泥船新型襟翼舵舵力试验验证，表明计算公式对同类型的襟翼舵是完全适用的。
