Students will be exposed to a number of topics in rotorcraft engineering. Basic helicopter configurations, such as co-axial, tandem and autogiro, are compared. Course starts with actuator disc theory and moves to more sophisticated blade element techniques for both vertical and forward flight. Special cases include autorotation and flight in ground effect. Students are introduced to the use of dimensional analysis to reduce rotorcraft flight test data and standardise test results. Design considerations such as ground resonance, crash worthiness and fatigue safe life will also be discussed. Linearised models of helicopter dynamics are developed proceeding to useful conclusions regarding helicopter stability and flight control.
