The invention discloses an arranging method of an airfoil control surface, and relates to the technical filed of airfoil designs. The arranging method of the airfoil control surface comprises the following steps of step I, obtaining the pressure distribution under a complete flow field state, and obtaining the lift distribution of a lift coefficient in the spanwise direction of an original span airfoil; step II, clipping the original span airfoil so as to obtain a new airfoil, and obtaining the lift distribution of the lift of the new airfoil in the spanwise direction of the new airfoil; step III, amending the high-speed CFD result of the clipped new airfoil; and step IV, arranging new control surfaces at positions where the spanwise lift distribution of the high-speed CFD result of the new clipped airfoil is the same as that of the high-speed CFD result of the original span airfoil, and determining a new control surface width. The arranging method disclosed by the invention has the advantages that the control surface arranging positions obtained by the arranging method can achieve a control surface hinge force moment which is obtained by the measurement and is relatively close to the actual situation; the improvement of the airfoil design is facilitated; the property of the airfoil is improved; and the service life of the airfoil is prolonged.
Description
technical field [0001] The invention relates to the technical field of wing design, in particular to a method for arranging wing rudder surfaces. Background technique [0002] With the continuous increase of society's demand for flight time and range of aircraft, in order to achieve higher aerodynamic efficiency, the aspect ratio of aircraft will also increase accordingly. Therefore, aircraft with super large aspect ratio is an important direction of current development. At present, there are two ways to obtain hinge torque, one is special wind tunnel test, and the other is CFD simulation calculation. However, a wing with a large aspect ratio will have a large elastic deformation in the high-speed wind tunnel test. As far as the current hinge moment measurement balance is concerned, the excessive deformation of the wing will have a greater impact on the accuracy of its measurement or even It affects the normal operation of the balance, making it difficult to obtain accurate...
