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研究轴来开发：（i）应用于旋翼机和飞机的先进飞行动力学和控制，以及ii）使用航空伺服弹性知识的飞机变形应用的主动控制技术。在第一轴中，将使用新的非线性优化算法开发旋翼机的飞行动力学建模。还将根据最少量的飞机几何数据，针对不同的飞行状态进行飞机稳定性分析。这些新方法将使用现有的旋翼机飞行测试数据以及商用和军用飞机的几何数据进行验证。在第二轴上，研究航空系统的机翼和其他几何表面将配备灵活的蒙皮，通过各种主动控制系统，它们可以变形，以提高其空气动力学性能。研究飞机飞行模拟器、大型亚音速风洞和研究航空系统将用于实验验证。
