研究了刚性和柔性飞机的多学科飞行动力学模型， 用于飞机设计过程的各个领域和阶段，例如飞行载荷 分析和飞行控制律设计。这些模型必须足够准确，但 允许在合理的时间内进行数千次模拟（即“可循环”）。 根据不同的应用，飞行动力学模型需要在不同的环境中可用。 形式，如用于非线性仿真的ODE，用于控制分析的线性状态空间模型， 等多学科飞行动力学模型开发中的一个主要挑战是 处理和整合来自各种来源的数据，消除重叠，并填充 在具体数据缺失的情况下，在过去十年中，德国航空航天中心的 机器人和机电一体化已经为这些任务开发了方法和工具，以及 适用于飞机设计分析的各种形式的模型实现。最近， 这些方面已经被集成在标准化的有效模型集成过程中， DAMIP（DLR Aircraft Model Integration Process）DAMIP使用数据结构 VarLoads是与空中客车公司合作开发的，并得到了适当的支持。 方法和工具。本文将给出DAMIP的概述，以及一些 最近的应用实例。
Multi-disciplinary flight dynamics models for rigid and flexible aircraft are used in various areas and stages of the aircraft design process, like for example flight loads analysis and flight control law design. These models must be sufficiently accurate, but also allow for thousands of simulations in a reasonable amount of time (i.e. ’loop-capable’). Depending on the application, flight dynamics models need to be available in various forms, like ODEs for nonlinear simulation, linear state space models for control analysis, etc. A major challenge in development of multi-disciplinary flight dynamics models is the handling and integration of data from various sources, removing overlaps, and filling in gaps in case specific data is missing. During the last decade, the DLR Institute of Robotics and Mechatronics has developed methods and tools for these tasks, as well as for model implementation in various forms suitable for aircraft design analysis. Recently, these aspects have been integrated in a standardized efficient model integration process, called DAMIP (DLR Aircraft Model Integration Process). DAMIP uses the data structure of VarLoads, which is developed in cooperation with Airbus, and is backed by appropriate methods and tools. In this paper an overview of DAMIP will be given, as well as some recent application examples.
