The Hinge Moment Optimization of Rudder base on CFD Numerical Simulation

摘要

The paper introduce structured grid division, use CFD numerical simulation and FLUNET software to conduct the simulation calculation for the hinge moment of rudder. To illustrate the problem, we select two unused plane airfoil An axis-symmetric rudder, one for the special design of the plane rudder. Calculated at 0.4～1.8 Ma, different rudder angle, angle of attack different hinge moment value, and compare them ultimately come to a flat airfoil optimization program, making the steering hinge moment to meet the indicators proposed.
