Principles of Flight II (FSI-OZ2)

Academic year 2018/2019
Supervisor: doc. Ing. Vladimír Daněk, CSc.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The goal is to familiarize students with basic problems of flying characteristics of an atmospheric aircraft, flight stability and controllability. Students will learn to judge the influence of operating parameters and flight conditions on aircraft flying characteristics.
Learning outcomes and competences:
Familiarizing with basic criteria for evaluating flying characteristics of an atmospheric aircraft. Qualitative and quantitative considering of flight performance and dynamic behaviour regarding piloting and optimal use of aircraft during flying activity.
Prerequisites:
The basics of mathematics - differential and integral calculus, common differential equations. The basics of common mechanics – force effect on a body, kinematics, dynamics.
Course contents:
Static and dynamic longitudinal stability. Neutral point, static margin. Static directional stability. Static lateral stability. Factors affecting static lateral stability - dihedral and sweep angle of wing. Dynamic directional-lateral stability - spiral divergence, stable and unstable Dutch roll motion.
Dynamic stability modes and their influence on aircraft handling. Controllability and maneuvrability. Pitch (longitudinal) control, yaw (directional) control and roll (lateral) control. Trimming. Operating limitations.Aerodynamics of propeller.
Flight mechanics of the basic regimes - straight horizontal steady flight, climb, descent and turns. Asymmetric thrust.
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:
Conditions for obtaining the course-unit credit: participation in the course (80% at the minimum), presentation of calculation tasks records. The credit is necessary to be admitted to examinations. The exam has written form (the essential one) and oral parts. Evaluation process fulfils the University requirements.
Controlled participation in lessons:
Lectures and seminars are compulsory, and the attendance (80% at the minimum) is checked and recorded. The absence (in justifiable cases) can be compensated by personal consultation with the lecturer and elaboration of individually assigned topics and exercises. Individual tasks must be finished and handed in the week credits are awarded at the latest.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Exercise  13 × 1 hrs. compulsory
