Aerodynamics of Flight | Helicopter Instructor

Define and discuss the four forces acting on an aircraft in straight-and-level and unaccelerated flight. Give examples of how the combinations of these forces act on the airframe. Thrust—the forward force produced by a powerplant/propeller or rotor. It opposes or overcomes the force of drag. Drag—a rearward, retarding force caused by disruption of airflow by […]
