Designing a kiteplane, and a little on how to control it

Xflr5 stability analysis usually is not accurate. You could make a generic 6dof model and add aerodynamic and inertia data into it.

small unmanned aircraft theory and practice is a good book for that.

Did you do any aerodynamic analysis …?

Hello builders

This online free tool lets you design and build complex wings with ribs and spars. No CAD skills needed!

You can export PDf, DXF or STL for cutting by hand, using cnc/laser or 3D print.

Reddit comment:

This paper develops a more intuitive way of understanding the emergence of lift using conservation principles. To my knowledge its the most up to date theory of lift

Reddit comment:

NASA uses the term “Flow Turning” as a catch-all word to explain the process. Their Guide to Aerodynamics page goes into a fair amount of detail about what actually produces lift, and also explains three commonly stated incorrect theories.

Used open access textbook:

Introduction to Aerospace Structures and Materials

This book provides an introduction to the discipline of aerospace structures and materials. It is the first book to date that includes all relevant aspects of this discipline within a single monologue. These aspects range from materials, manufacturing and processing techniques, to structures, design principles and structural performance, including aspects like durability and safety. With the purpose of introducing students into the basics of the entire discipline, the book presents the subjects broadly and loosely connected, adopting either a formal description or an informal walk around type of presentation. A key lessons conveyed within this book is the interplay between the exact science and engineering topics, like solid material physics and structural analysis, and the soft topics that are not easily captured by equations and formulas. Safety, manufacturability, availability and costing are some of these topics that are presented in this book to explain decisions and design solutions within this discipline.
