aerodynamics of a rotary wing type aircraft

[attachment=18736]

Introduction to basic aerodynamics

Newton's Laws of Motion

Fluid flow and Airspeed measurement. (Bernoulli’s

Principle)

Airfoils in general

Applications:

Sustentation (A Wing or Rotor Blade)

For Stability (As a Fin)

For Control (A Flight Surface, such as a Rudder)

For Thrust (A Propeller or Rotor Blade)

aerodynamic forces necessary to keep any body aloft

are produced when air passes about the rotor blades

and this is known as “Lift”

Centrifugal force & Centripetal Force

Because of its rotation and weight, the rotor system is

subject to forces and moments peculiar to all rotating

masses. One of the forces produced is Centrifugal

Force.

It is defined as the force that tends to make rotating

bodies move away from the centre of rotation.

Centripetal Force. It is the force that counteracts

centrifugal force by keeping an object a certain radius

from the axis of rotation.
