• Aviation, Semester 1, position 5

1. Introduction to rotary lifting surface vehicles. 2. Introduction to rotor aerodynamic theory. 3. Design of helicopters. 4. Performance of helicopters.

1. Understanding of aerodynamic VTOL schemes. 2. Selection of the aerodynamic scheme in helicopter design. 3. Mastering theoretical foundations of rotary wing aerodynamics. 4. Ability to calculate aerodynamic and performance characteristics of the helicopter. 5. Ability to design rotor blade. 6. Ability to conceptually design helicopter. 7. Ability to apply modern software tools in design of helicopters. 8. Ability to optimize helicopter design parameters.

In theoretical part the following is taught: VTOL aircraft, Theory of ideal rotor, Blade element theory, horizontal flight of a helicopter, vertical flight performances, horizontal flight performances, Stability of a helicopter, design schemes of a helicopter, helicopter control, Design of rotor blade. EASA regulaations for helicopter and transmission design.

Theory is applied to chosen helicopter. Practical work of the student is monitored by MOODLE. Lectures are downloaded using online access. Homework and other materials to master lectures are supplied. Students do projects in a group and finally present results to other students.

Suggested: Aerodynamic design

Lectures in electronic form. Simulations and movies are accessible via MOODLE and internet.
