Drag
When an aircraft or any other body moves in atmosphere it
experiences air resistance which retards its forward motion. This force is
called drag. Drag occurs when an aircraft or any other object moves in air and
it depends on the shape of the flying object. Aircrafts and other flying objects are
designed in such a manner to reduce the drag, which increases the efficiency of
the aircraft.
Drag is experienced parallel to relative airflow. Drag is
directly balanced by thrust produced by a propeller or an engine. Amount of
thrust required to balance the drag depends of amount of drag, more thrust is
required to balance a greater drag force produced.
If the drag produced by an aircraft is low then the aircraft
consumes less fuel and operating costs are also low. The total drag acting on
an aircraft includes
- Profile drag
- Induced drag
- Interference drag
Profile drag is further divided into
- Form drag
- Skin friction drag
