NA PagesConceptual Aircraft Design Electronic Textbook
The aim of this manual is to briefly state theoretical bases of methods and models used in conceptual airplane design, to develop and consolidate understanding of the relations between the main airplane parameters and characteristics, and to prepare students to perform their graduation projects. This tutorial contains only necessary information for obtaining the first experience in the conceptual airplane design. Also it is supposed that students refer to textbooks and other scientific sources, which seems difficult at first. In this case this tutorial should be used as a guide-book for additional information sources.
