AERODYNAMICS
Wing Design
The wings of a fixed wing aircraft provide the necessary lift for take-off and cruise flight. Wing geometry affects every aspect of an aircraft’s flight.
Fuselage
The fuselage is the part of the aircraft that contains the cockpit, passenger cabin or cargo hold.
Propulsion
Aircraft propulsion may be achieved by specially designed aircraft engines, adapted auto, motorcycle or snowmobile engines, electric engines or even human muscle power. The main parameters of engine design are:
Maximum engine thrust
Fuel consumption
Engine mass
Engine geometry
MASS
The weight of the aircraft is the common factor that links all aspects of aircraft design such as aerodynamics, structure, propulsion together. An aircraft's weight is derived from various factors such as empty weight, payload, useful load, etc.
STRUCTURE
The aircraft structure focuses not only on strength, but also on fatigue, fail-safety, corrosion, maintainability and ease of manufacturing.
WEIGHT AND LIFT
Weight's opposing force is lift, which holds an airplane in the air. This feat is accomplished through the use of a wing.
As air speeds up, its pressure drops. So the faster-moving air moving over the wing exerts less pressure on it than the slower air moving underneath the wing. The result is an upward push of lift. In the field of fluid dynamics, this is known as Bernoulli's principle.
