About

FM 1-51 CHAPTER 2 BASIC HELICOPTER AERODYNAMICS Section I. DYNAMICS AND AERODYNAMICS 2-1. General An aviator needs to understand the physical laws related to dynamics and aerodynamics and how they apply to the helicopter and its control. This section defines, explains, and illustrates basic dynamic and aerodynamic principles which a rotary wing aviator would be required to know. For additional information on basic helicopter aerodynamics, see FAA Advisory Circular (AC) 61-13, Basic Helicopter Handbook. 2—2. Types of Airfoils An airfoil is any surface designed to produce a lift or thrust reaction when air passes over it. Airfoils include airplane wings, helicopter rotor blades, and propellers. Airplane wings and helicopter rotor blades have airfoil sections with upper and lower surfaces carefully engineer- designed for a specific set of flight characteris- tics.
