Introduction to Turbomachinery Aerodynamics — Lesson 1

This lesson covers the fundamentals of aero elasticity, its applications, and the problems encountered in this field. It delves into the study of the interaction of aerodynamics, inertia, and elasticity, and how these interactions affect aircraft design. The lesson also discusses the different types of aero elasticity problems such as static aero elasticity, dynamic aero elasticity, and unsteady aerodynamics. It further explores the influence of wing design, aircraft structures, and control theory on aero elasticity. The lesson also touches on the historical development of aero elasticity and its significance in modern aircraft design. For instance, it explains how the Wright brothers' biplane design was successful due to its partial twist, which helped avoid aero elastic problems.
