Course Objective: Familiarisation with helicopter systems and relevant maintenance procedures.

Course Contents: Introduction. Fundamentals of helicopter aerodynamics and performances. Types of joinings of the main rotor blades (joints – semi-fixed and fixed rotors). Helicopter control (cyclic change of stroke, collective change of stroke, flying by course). Fundamentals of static and dynamic stability. Stabilisers. Main rotor and its head: structure and driving properties. Tail rotor and its head: structure and driving properties. Rotor arms: structure and driving properties. Helicopter fuselage: structure and parts. Helicopter powerplants and power transmission: types of engine and drives, reduction gears. Basic vibration analyses. Co-conical property of the main and tail rotor blades. Static and dynamic balancing of aerodynamic bearing surfaces. Rotor technical maintenance. Effect and significance of icing. .

General and Specific Competencies (Knowledge and Skills): Familiarisation with the feature and role of particular helicopter parts. Recognising the nature and type of load on particular parts of helicopter design. Assessing the effect of possible damage of the design on the helicopter airworthiness. Comprehension of the design maintenance technology. .
