Fundamentals of Helicopter Aerodynamics

What it is about

You will learn the fundamental aerodynamic principles for helicopter rotor aerodynamics in hover and forward flight. In the end you will be able to apply the relevant theories (Momentum theory, Blade Element and mixed theories), assess power requirements and operating limits, and evaluate the effects of blade geometry and motion on flight performance.

What you will be able to do

• Understand the fundamentals of rotor aerodynamics in hover and forward flight
• Apply Momentum Theory (including Glauert) and Blade Element / BEMT
• Power calculation: induced and parasitic drag, profile drag
• Assess influences: blade twist, planform, surface loading
• Identify rotor limits: compressibility, stall, reverse flow
• Fundamentals of autorotation and its quantification
• Assess when which analysis level or method to apply
