Structure and strength of aircraft acquaints students with the basic conceptual arrangements of aircraft in relation to other fields, especially aerodynamics, flight mechanics and aircraft materials. Furthermore, the course focuses on the description of individual airframe components with emphasis on the basic principles of load determination, design and strength analysis. An integral part of this knowledge is the introduction to the theory of thin-walled structures and their calculation.
Learning outcomes of the course unit
The course Aircraft Structure and Strength enables students to gain knowledge about aircraft design, load calculation and strength analysis. The student will learn to work with prescription requirements and on the basis of them design part.
Basic knowledge of general elasticity and strength. Basic knowledge of physics, kinematics and dynamics.
