Embodiment Construction

[0090] refer to Figure 1~2 . The specific steps of the aircraft overall follow-up optimization method for reducing the aerodynamic coupling characteristics of the present invention are as follows:

[0091] Step 1: The objective function of the aircraft overall follow-up optimization is established.

[0092] The overall follow-up optimization objective function aimed at improving the aerodynamic coupling characteristics of the aircraft selects the evaluation index of the aerodynamic coupling characteristics of the aircraft—the characterization model of the coupling degree, including the coupling degree of the rudder deflection to the roll channel Coupling degree of rudder deflection to pitch channel Coupling degree of differential rudder deflection to yaw channel Coupling degree of differential rudder deflection to pitch channel which is

Abstract

The invention discloses an air craft universe following and controlling optimization method capable of reducing pneumatic coupling properties, and aims to solve the technical problem that an aircraft universe designed by an existing method is weak in performance. The technical scheme is that building an aircraft universe following and controlling optimized objective function, confirming an aircraft universe following and controlling optimized constraint condition, selecting an aircraft universe following and controlling optimized decision variable, confirming an aircraft universe following and controlling optimized decision variable optimizing boundary, and building an aircraft universe following and controlling optimized complete model and aircraft universe following and controlling optimization based on a genetic algorithm. An obtained aircraft optimized appearance effectively reduces the pneumatic coupling properties of aircrafts.

Description

technical field [0001] The invention relates to an overall follow-up control optimization method for an aircraft, in particular to an overall follow-up control optimization method for an aircraft with reduced aerodynamic coupling characteristics. Background technique [0002] The overall optimization design of the aircraft is mainly based on the multidisciplinary optimization design method. This method divides the disciplines involved according to the optimization goal of the overall design of the aircraft, and decomposes the overall design of the aircraft into multiple disciplines such as engine design, aerodynamic parameter design, shape design, projectile structure design, and ballistic design. For example, the document "Application of multidisciplinary design optimization in the overall design of aircraft ("Journal of Missiles and Guidance" 32 (3), 2012.6.pp.39-43)" regards the multi-objective function composed of the maximum range and the minimum take-off mass as the ai...
