| 摘 要： | 由于受机身绕流的影响,后掠机翼翼根的流动非常复杂,翼根气动设计是后掠机翼气动设计的难点.本章发展了基于Kriging代理模型的双层粒子群优化算法,结合雷诺平均N-S方程流场求解器进行了考虑机身干扰的机翼气动外形综合优化研究,在保证机翼相对厚度和容积不减的前提下降低了气动阻力、低头力矩和翼根弯矩.而考虑非设计巡航状态的多...

| Abstract: | Aim.The introduction of the full paper reviews some papers in the open literature and then proposes our better optimization method,which is explained in sections 1 and 2.Section 1 presents the double-layer quantum-behaved particle swarm optimization(QPSO) algorithm that uses the Kriging surrogate model.Considering fuselage interference,section 2 optimzes the aerodynamic shape of a wing,using the Reynolds-averaged Navier-Stokes flow solver;its core consists of:(1) we use the Hicks-Henne analytical function m... |
