New modeling and simulation methodologies will be developed through two major research axes: (i) advanced flight dynamics and controls applied on rotorcraft and aircraft and ii) active control technologies for aircraft morphing applications using aeroservoelasticity knowledge. In the first axis, flight dynamics modeling for rotorcraft will be developed using new nonlinear optimization algorithms. Aircraft stability analyses, for different flight regimes, based on a minimum amount of aircraft geometrical data, will also be performed. These new methodologies will be validated using available rotorcraft flight test data, as well as geometrical data for business and military aircraft. In the second axis, the wings and other geometrical surfaces of a research aerial system will be equipped with flexible skins that will allow, through various active control systems, their morphing, to improve its aerodynamic performances. A research aircraft flight simulator, a large subsonic blown down wind tunnel and a research aerial system will be used for experimental validation.

新的建模和仿真方法将通过两个主要的研究轴开发：（i）在旋翼飞机和飞机上应用的先进飞行动力学和控制以及ii）使用气流弹性知识进行飞机变形应用的主动控制技术。在第一个轴中，将使用新的非线性优化算法开发转子飞行的飞行动力学建模。还将根据最低数量的飞机几何数据进行飞机稳定性分析。这些新方法将使用可用的Rotorcraft飞行测试数据以及商业和军用飞机的几何数据进行验证。在第二轴上，研究空中系统的机翼和其他几何表面将配备柔性皮肤，通过各种主动控制系统，它们的变形，以改善其空气动力学性能。研究飞机飞行模拟器，大型亚音速吹入风洞和研究空中系统将用于实验验证。
