Aircrafts and aerodynamics
The main parts of an aircraft are: the fuselage, the wings, the horizontal stabilizer,the vertical stabiliser, the landing gear, and of course the engine(s) Control Surfaces: Right and Left Aileron, Elevator, Rudder, and Trim Tabs
Four Forces on an Airplane
The four forces which act upon an aircraft are:
- LIFT acts upwards at right angles to the airflow through the centre of pressure.
- DRAG is the backward force which opposes the forward motion of the aircraft and and acts parallel and in the reverse direction to the aircraft movement.
- THRUST is the forward propulsive force provided by the engines.
- WEIGHT is the total weight which acts vertically downwards through the centre of gravity.
- LIFT<up and down>WEIGHT
- THRUST<forward and back>DRAG
NASA's Beginners Guide to Aerodynamics - Supplement your of study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance; the three forces (lift, drag, and weight) that act on a glider; and finally, the four forces that act on a powered airplane. There are many interactive pages designed to illustrate aerodynamics.
