Principles of Flight I (FSI-OZ1)

Academic year 2023/2024
Supervisor: doc. Ing. Pavel Zikmund, Ph.D.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The goal is to familiarize students with the basic aerodynamics of atmospheric aircraft, the principle of forces and moments emergence on aircraft. Students will learn to apply practically their knowledge of aerodynamics in pilot practice for the purpose of higher flight safety.
Learning outcomes and competences:
The students gain basic knowledge and habits for the aerodynamic application usable for flying from the piloting point of view. They acquire knowledge of flying theory necessary for effective and safe aircraft traffic.
Prerequisites:
The basics of mathematics - differential and integral calculus, common differential equations. The basics of common mechanics – force effect on a body, kinematics and dynamics. The basics of fluid mechanics.
Course contents:
Explaining of aerodynamic force and moment emergence on aircraft. Basic aerodynamic laws –equation of continuity, Bernoulli’s equations. Aerodynamic characteristic of profile and finite aspect ratio wing, drag due to lift. Aircraft aerodynamic characteristic – parasitic drag, interferential drag. High lift and drag devices. Compressibility effect on aircraft aerodynamic characteristic – subsonic, transonic, and supersonic speeds. The swept effect, Mach number, shock waves.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:

The course ends with a classified credit. The condition for granting a classified credit is 95 % physical participation in all forms of teaching. Furthermore, it is necessary to submit completed assignments within exercises and self-study. Demonstration of knowledge takes place in the form of a test. Classification according to the Study and Examination Regulations of the FME.

 

 

 

 
Controlled participation in lessons:
Lectures and seminars are compulsory, and attendance is checked and recorded. The absence (15%-20%) can be compensated by personal consultation with the lecturer and elaboration of individually assigned topics and exercises. All tasks must be finished and handed in the credit week at the latest.
