size and Usage
Military Civil Experimental Model
 Wright Brothers with their FLYER flied for a 39.5 Km Distance
 World War I 1st air force war
 Jet engine invention in Germany and UK between 1918 – 1939
 Commercial Aircrafts after World War II
Aircraft History

3. Introduction
In aircrafts industry forming technology plays a basic role in
manufacturing most of necessary and critical parts such bolts ,
rivets , body , wings.
in this presentation we will seek several applications of forming
technology in aircrafts industry.

5. a. Function :
Creates the left needed for the
aircraft takeoff and balancing the
plane during the flight .
b. forming process :
Its made by stretching and sheet
metal rolling
Wings

6. Spars
a. Function :
Is often the main structural member of the
wing
Ribs may be attached to the spar or spars,
with stressed skin construction
b. Forming process :
Manufactured by Rolling , piercing

7. Ribs
a. Function :
Are forming elements of the structure of a
wing, especially in traditional construction
Usually ribs incorporate the airfoil shape of the
wing, and the skin adopts this shape when
stretched over the ribs
b. Forming process:
Its made by rolling operation and piercing

8. Stringers
a. Function :
is a thin strip of material to which the skin of
the aircraft is fastened.
In the fuselage
b. Forming process :
Manufactured by shape rolling

9. Wing box
a. Function :
It keeps the wing fixed to the fuselage
b. Forming process :
Manufactured by hot forging and sheet
metal stretching

10. Turbine Comp. Blades
a. Function :
Engine blades serves in high temperatures
and with high mechanical loads , if one blade
failed , most
of times it means the failure of the whole
engine
b. Forming process :
Using Isothermal Forging it decreases
the need deformation force for the metal
and less temperature losses also we gain
a uniform deformation

11. Engine Nacelle
a. Function :
Is a housing, separate from the
fuselage , that holds engines ,
fuel, or equipment on an aircraft
b. Forming process:
Manufactured by sheet metal
stretching

12. Leading Edge
a. Function :
Rolling Leading Edge Skin using (farnham Contour
rolls)
To get the shape of the leading edge
b. Forming process:
Its usually made by sheet metal rolling then its bend
by the
Bending process .

13. Farnham Rolls

14. Aircraft Skin
a. Function :
It covers the whole plain structure to provide the
Least air drag resistance , it also carries the wings
weight
b. Forming process:
Using Stretch Forming and rolling
We manufacture the aircraft skin which
Covers the aircraft structure
Also for manufacturing the fuselage
Which is very critical part of the
Aircraft body

15. Aircraft Fuselage
a. Function :
The main body that carry the all
components of the airplane
Manufactured by rolling , stretching
b. Forming process :
The steel section are made by the
shape rolling and bending process
then they are assembled by rivets

16. Jet Engine Nose
a. Function :
a solid of revolution shape that
experiences minimal resistance to rapid
motion through such a fluid medium, which
for aircraft and rockets, below Mach
b. Forming process:
Jet engine nose is manufactured using
Spinning process to ensure
the surface smoothness of that area,
and the presence of any
discontinuities in the shape.

17. Rivets
a. Function :
Used in Connecting any 2 sheets in wings , the
the countersunk headed rivet is chosen to
reduce the turbulence on the jointed parts
b. forming process :
Using Cold Forging , Counter Sank Rivets
Made From Stainless Steel or Aluminum Steel

18. Aircraft cables
a. Function :
This is important for precise control Of the
rudder , elevator and flaps .
b. forming process :
Its made by wire drawing

19. pipes
a. Function :
Transfer fluids in the aircraft between
Internal units
b. forming process :
Manufactured by pipe drawing ,
Hydrostatic drawing
