Course detail

Aircraft Propulsion

FSI-OLEAcad. year: 2019/2020

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.

Co-requisites

Not applicable.

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.
