This course is a combination of aircraft performance and basic flight mechanics. It also includes the basics of the aerodynamic build-up of an aircraft to determine aerodynamic coefficients and the so-called stability and control derivatives. Except for takeoff and landing rolls, aircraft performance analyses entail analysis of steady flight conditions. Flight mechanics deals more with the trim and static stability of the aircraft for the steady flight conditions. Steady flight conditions are typically the starting point for small-perturbation dynamics and stability analyses.

Aeroelasticity deals with interactions between aerodynamic loads and elastic static and/or dynamic deformations, as well as the influence of the interactions on aircraft performance. The performance of interest may include stability of structures immersed in an airflow (e.g., divergence, buffeting, and flutter), rejection of external disturbances (e.g., gust alleviation), and controllability of flight vehicle trajectory (attitude or motion). Structural mass and stiffness are often tailored to change the aerodynamic load distributions on lifting surfaces. Aeroelasticity is not just fluid mechanics or solid mechanics. Its major emphasis is the fluid-structure interaction. This course focuses on understanding the phenomenology of aerodynamic and structural interactions, instead of the complicated modeling processes. The material is relatively self-contained as we will introduce concepts such as mass and stiffness matrices, shear centers, aerodynamic coefficients, and aerodynamic centers, and then build on these concepts. The students will have access to some simple models, which may become complicated when the fluid-structure interaction is considered. With the study in the class, the students will be able to analyze fundamental aeroelastic phenomena and solve the problem by using a numerical tool. Students should learn the concept of aeroelastic tailoring and structural designs with aeroelastic constraints.
