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.
