Helicopters (FSI-OV0)

Academic year 2021/2022
Supervisor: doc. Ing. Miloslav Petrásek, CSc.  
Supervising institute: LÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The course objective is to provide students with the basic knowledge of aerodynamics and design of structures of helicopters.
Learning outcomes and competences:
Students will acquire knowledge necessary for solving basic computational tasks in the field of helicopter performance and strength of basic airframe parts. They will be able to basically assess the qualities of individual types and will be ready for practical training on a specific type of helicopter.
Prerequisites:
Basic knowledge of low speed aerodynamics and basics of flight mechanics , flight performances and properties.
Course contents:
The aim of the course is to provide students with knowledge about helicopters to such an extent that they understand the function of individual parts of aircraft with a rotating carrier. Attention is focused mainly on aerodynamics of the supporting and balancing rotor, helicopter parts design and their functions, flight performance and stability and controllability. The list should also include an introduction to the basic calculation procedures in the field of aerodynamics, performance and helicopter components.
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:
Students will be evaluated according to the participation and quality of work in computational exercises and according to the level of elaboration of the selected semester work.
Controlled participation in lessons:
Attendance at lectures is not obligatory. Controlled participation in lessons: Attendance at seminars is obligatory and checked by the teacher.
