Course detail
Aircraft Propulsion
FSI-OLE-A Acad. year: 2019/2020 Winter semester
The Aircraft Engines course provides a comprehensive overview of the principles of operations, work cycles, and the design of aviation propulsion units. In the course the students will get a knowledge about the work of piston, turbine and ramjet aircraft engines. Construction layout and auxiliary systems are discussed in detail to ensure their operation. Students are acquainted with the technological and physical constraints of various types of propulsion units and the current technologies used in their construction. Part of the course is also a more detailed analysis of environmental and certification requirements for aircraft engines and directions for their future development. The course also focuses on the maintenance of modern propulsion units based on the modularity of their design.

Learning outcomes of the course unit
The course of Aircraft Propulsion gives basic knowledge of principles, design, materials, operating characteristics and maintenance of modern aircraft engines. Students will be able to assess engines according their function, and economical operation.
Prerequisites
Basic definitions, laws and equations of physics, thermodynamics and fluid mechanics. Ideal and real gas, force, energy, work, heat, enthalpy, entropy, gas state equation, changes of gas states, continuity and Bernoulli's equations, basics of heat transfer.
Planned learning activities and teaching methods
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
Attendance at seminars and completing all tasks is necessary for the course-unit credit award.
accreditation. Write and oral examination consists of three parts: 1. Simple computational problem 2. Piston engine theoretical question 3. Jet engine theoretical question. All three parts have the same weight in the resulting evaluation.
Aims
The objective of the course is to inform students of current state and development of aircraft propulsion and to provide them with the knowledge necessary for selecting the proper engine, its economical/ecological operation and maintenance.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars is compulsory. In the case of a justified absence, students are required to work out an alternative individual assignment. Continuous checking is done at seminars.
