ABSTRACT: The plane is an aerodyne equipped with a flat bearing surface ensures
sustentation due speed. Travel speed can be achieved either by the action of powertrains or
action component weight (for flight or flight descent without engine).
KEY WORDS : electrical erosion, materials, construction of aircraft speed.

1.INTRODUCTION

Occurred in the early 20th century, the first
aircraft requires much courage and skill to
fly them. In that time, they were neither
fast nor spacious. First controlled flight
powered with a heavier than air they did on
December 17, 1903 Wright brothers first
effective self-propelled flight was made by
Traian Vuia on March 18, 1906 and the
first official flight was made by Alberto
Motor Santos-Dumont on November 12, 1906.Inventor Henri Coanda aircraft
without the propeller, which is powered by
a jet engine. Louis Blériot was the first
pilot to cross the English Channel in 1909.
Charles Lindbergh made the first crossing
of the Atlantic alone and without stopping
in 1927. In 1933, Wiley Post was the first
airline pilot who has done one tour the
world. He traveled 25 000 km 27 days, 54
hours and 78 minutes
.

4.CONCLUSIONS.

On an aircraft in flight four acting forces
have to be balanced. A force in general can
be interpreted as a push or pull on an
object in a certain direction. Drag (the
motion) is the aerodynamic force that
opposes any body moving in a fluid. The
size of this force is influenced by several factors: the shape of the aircraft, the
density and composition of the air speed.
Direction of this force is always opposite
to the direction of flight and we believe
that her "focus" in a single point called the
center of pressure.
