Introduction to aircraft aerodynamics
This introductory course in English is designed to help you understand the relationship between the geometry and aerodynamic performance of subsonic aircraft. The course includes theoretical and applied parts, as well as additional materials.
The first part covers those topics of subsonic aerodynamics that are necessary for effective work with the applied part of the course: the flow models, some fundamental equations, concepts, and theories of aerodynamics. The key topic of the theoretical section is the development of low-fidelity numerical methods used for aerodynamic analysis at the initial design stages.
The applied portion of the course covers some general trends in the aerodynamic design of aircraft parts and an aircraft as a whole, with the goal of optimizing aircraft aerodynamic performance. The objective of this course’s part is to show how, using the tools of theoretical and applied aerodynamics, one can design an aerodynamically better aircraft.
In addition to video lectures with presentations, we have included in the course the lecture notes with the list of references, as well as the equation and designation sheets (for convenience, the designations adopted in both English and Russian technical literature are given).
The course also includes interviews with experts of the Central Aerohydrodynamic Institute, a video exploring the MAI aerodynamic laboratory, including its history, and a video tour of the MAI aircraft hangar.
The material in this course assumes:
- some knowledge of technical English;
- familiarity with differential and integral calculus, vector analysis, and;
- the usual physics background.
To work on the course, students need the following software:
- MS Office;
- any CAD program;
- X-Foil or similar codes for aerodynamic analysis
- optional: any CFD package.
