Problems solved by technology

[0003] At present, the rudder effect estimation method based on the force analysis of individual rudder surface components is generally used. This method is suitable for the situation where the flow near the rudder surface is less disturbed by other parts such as the body. The influence of missile body interference cannot be taken into account by using the existing method, and the accuracy of the estimated rudder effect data is low

Abstract

The invention relates to the technical field of aircrafts, and discloses a rapid rudder effect estimation method. The method comprises the steps that CFD calculation is carried out based on the zero-rudder-deviation reference state of the aircraft to obtain the aerodynamic coefficient Cy of a rudder surface under each missile body attack angle alpha under the zero-rudder-deviation reference state;carrying out center interpolation on the aerodynamic coefficient Cy to obtain an aerodynamic coefficient Cy, alpha of the control surface under each missile body attack angle; and based on the binaryarray (alpha, Cy, alpha), calculating aerodynamic coefficient increment caused by control surface deflection delta under any missile body attack angle alpha 0, and estimating the control effect basedon the aerodynamic coefficient increment, so that the high-precision rapid estimation of the control effect can be realized by considering the missile body interference influence.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a method for quickly estimating rudder effect. Background technique [0002] In the demonstration stage of the aircraft overall plan, the layout form of the control surface and the evaluation of the control rudder effect are indispensable key links, which are directly related to the success or failure of the overall aircraft plan. However, there are many design variables in the stage of program demonstration, and the detailed CFD calculation of control rudder surfaces with various dimensions (such as different sweep angles, aspect ratios, and root-to-shoot ratios) to obtain rudder effect data requires a huge amount of work and a period of time. Too long is not conducive to the rapid iterative optimization of the overall plan. Therefore, there is an urgent need for a rapid estimation method to obtain the control rudder effect in the scheme demonstration stage. [0003] At prese...
