Aerodynamics (the study of force) comes from the Greek: water = air and
dynamic = force. Therefore
we can conclude that the aerodynamics is a study of the movement of an object
in the air. Air
force science is a continuation of the older science is the science of the
hydrodynamic force of water or the air force and science are closely connected
with some of the other sciences, namely the natural sciences (physics),
mathematics (math), science style (mechanics), and meteorology
(meteorogia) the supply of information about the still air rights, especially
about the changes experienced by the air if the altitude increases.
In
1810 Sir George Canley argues that the forced air blowing against the direction
of motion of the wings in the air or fluid. Then
in 1871 Pranoim Wenham airfoil plotting a curve like the shape of bird wings. Also
in this year's Wenham who first made wind tunnel which is driven by steam
power. Airfoil
investigation was continued by the brothers Wreight conduct experiments with approximately
150 pieces of foil water beside the steering wheel complements the tools to
steer the aircraft is being terbang.dalam Newton Iaanc investigation has found
that forces air through the moving body lift ( lift and resistance / drag). In the years 1902-1907
kutti N Wilhelm (Germany), NE Janhowaki (Russia), Frederiek W. Launohoster
(England) discovered the theory of how the lift (elevator) on the airfoil.
With
the discoveries in the years above it is clear that the science of aerodynamics
is still new, and not an abstract knowledge such as science and mechanics
because up to now investigations are still ongoing.
Aerodynamics
is actually none other than the one who studies or investigates the properties
of air, the reactions and consequences arising from the movement of objects
through the air by the air or the movement of objects in the air. So
aerodynamics also means knowledge or investigation of object movements in the
air where the terms are closely related denganilmu flight.
The factors that
affect Aerodynamics:
-Temperature (air temperature)
- Air
pressure
-Air velocity
-Density / density of air
To
study the science of aerodynamics, there are some legal diantaramya
Newton's laws
Newton's
Laws I
Said
that the object at rest will remain silent while a moving object will keep
moving in straight lines and velocity tetapkecuali a style that is because of
external circumstances that forced him to change the
Newton's second law
Said
that changes in direct proportion to the amount of movement of the working
style and work along the lines of the style. Newton's
Second Law further says that a moving object will have a slowdown.
Newton's third law
Said
that the action is equal and opposite reactions. This
means that the force carried by the two bodies against each other equal and
opposite direction.
