概述了DLR-SIKMA项目--“复杂机动模拟”的最新成果。SIKMA项目的目标是开发一个数值工具来模拟自由飞行的气动弹性战斗机的非定常空气动力学，使用气动、飞行-机械和气动弹性耦合计算。为了实现这一目标，非结构化、时间精确的流动求解器TAU与一个求解飞行力学运动方程的计算模块和一个确定结构变形的结构力学程序相结合。通过使用重叠网格技术(嵌合体)，可以模拟具有可移动操纵面的复杂构型。
An overview about recent results of the DLR-Project SikMa-“Simulation of Complex Maneuvers” is presented. The objective of the SikMa-Project is to develop a numerical tool to simulate the unsteady aerodynamics of a free flying aeroelastic combat aircraft, by use of coupled aerodynamic, flight-mechanic and aeroelastic computations. To achieve this objective, the unstructured, time accurate flow-solver TAU is coupled with a computational module solving the flight-mechanic equations of motion and a structural mechanics code determining the structural deformations. By use of an overlapping grid technique (chimera), simulations of a complex configuration with movable control-surfaces is possible.
